Round saggar

Saggars are recommended when working with zirconium oxide. A saggar consists of the sintering bowl as the

bottom part and the spacer ring with ventilation

openings. The material is very resistant to temperature

changes and can also be used with short heating and

cooling times.

Rectangular saggars

For optimum utilization of the furnace chamber, the

material is placed in ceramic saggars. Up to three saggars

can be stacked in the furnace. The saggars have slits to

allow the air to circulate. The top saggar can be closed

with a ceramic lid.

Over-temperature limiters with manual reset/with automatic reset to protect against over-

temperature in the furnace chamber are available for Nabertherm GmbH furnaces either as

a standard feature (depending on the model series) or as additional equipment (customized

design).

The over-temperature limiter with manual reset/with automatic reset monitors the furnace

chamber temperature. The display shows the most recently set cut-off temperature. If the

furnace chamber temperature rises about the pre-set cut-off temperature the heating is shut

down to protect the furnace, the charge and/or the operating equipment.

DANGER

• Danger caused by incorrectly entered cut-off

temperature at the over-temperature limiter with

manual reset/over-temperature limiter with automatic

reset.

• Mortal danger

• If, as a result of over-temperature from the charge and/or the

operating equipment, a charge is likely to be damaged at this pre-

set cut-off temperature of the over-temperature limiter with

manual reset/over-temperature limiter with automatic reset, or if

the charge itself becomes a source of danger for the furnace or its

surroundings, the cut-off temperature must be reduced at the over-temperature limiter with manual reset/automatic reset to the

maximum permissible value.

Read the operating instructions of the over-temperature limiter with manual reset/with automatic reset before starting the furnace. The safety sticker must be removed from the

over-temperature limiter with manual reset/with automatic reset. Any time a change is

made in the heat treatment program, the maximum permissible cut-off temperature (alarm

trigger temperature) at the over-temperature limiter with manual reset/with automatic reset

must be checked or re-entered. Pos: 33 / TD/Bet rieb _Bedie nun g/die maxi male S olltem per atu r des Wär mep rog ra mms C ontr oller zwische n 5 °C u nd 3 0 °C ( TWB-TWW ) @ 3 9\m od_ 136 378 461 0371 _51 .docx @ 2 185 00 @ @ 1

We recommend setting the maximum setpoint temperature of the heating program in the

limiter between 5 °C and 30 °C, depending on the physical characteristics of the furnace, below the trigger temperature of the over-temperature limiter with manual reset/with

automatic reset. This prevents an unwanted triggering of the over-temperature limiter with

manual reset/with automatic reset.

Caution

Operating the furnace with explosive gases or mixtures, including explosive gases or

mixtures created as a result of heating/drying, is prohibited.

This furnace features no safety technology for processes which produce combustible

mixtures, for example debinding.

If the furnace is still used for such processes despite this fact, the concentration of organic gas mixtures in the furnace must never exceed 3% of the lower explosion limit (LEL). This

pre-requisite applies not only to normal operation but, in particular, to exceptional

situations such as process disruptions (caused, for example, by the failure of a power unit).

You must ensure that the furnace is adequately ventilated and vented.

Nabertherm offers a broad range of furnaces which were especially developed for processes involving the use of combustible gas mixtures.

The set-up instructions and safety regulations must be followed, otherwise the furnace will be deemed to have been used improperly, effectively cancelling any claims against

Nabertherm GmbH.

This level of safety when operating the furnace can be achieved only if all the necessary

measures have been taken. It depends on the furnace operator's diligence in planning these

measures and controlling how they are carried out.

The operator must ensure that

all harmful gases are removed from the workplace, for example by an extraction

system,

the extraction system is switched on,

the workplace is properly ventilated,

the furnace is operated only in a perfect operating condition and, in particular, that the

functions of the safety components are checked regularly.

the required personal protective equipment is available for and used by the operating,

maintenance, and repair personnel.

these operating instructions, including the supplier documentation, are kept near the

furnace. These instructions must be available at all times for anyone working with or on the furnace;

all the safety and operating instruction signs on the furnace can be read properly.

Damaged or unreadable signs must be replaced immediately,

furnace personnel are informed regularly about all issues involving occupational

safety and environmental protection and are familiar with all the operating

instructions, especially those involving safety,

a risk assessment is carried out (in Germany, covered of the Occupational Safety Act)

to determine any other hazards that may result from the working conditions particular

to the furnace's location,

17

all other instructions and safety guidelines that have been determined in a risk

assessment for the workplace are compiled in an operation manual (in Germany,

covered of the Ordinance Regulating the Use of Operating Equipment).

Only sufficiently qualified and authorized personnel may operate, maintain and repair

the system. This personnel must be trained in how to operate the furnace and must confirm their participation in the training with a personal signature. The training

program must be documented in detail. In case an operator is replaced, additional

training must also take place. The additional training may only be performed by

authorized, trained individuals familiar with the system. The additional training must

be painstakingly documented and participation must be evidenced by the names and

signatures of the participating employees. Pos: 67 / TD/Sich erh eit/De r Einsatz von Fä rbel ösun gen k ann zu ei nem üb erp rop ortio nale n Versc hleiß de r Heizel eme nte füh ren. .. @ 43\m od_ 137 111 529 958 8_51 .docx @ 2 335 30 @ @ 1 it

Risks during normal operation

Before switching the furnace on, check and ensure that only authorized persons are in the

working area of the furnace and that no one can be injured as a result of operating the

furnace.

Each time, before starting production check and ensure that all the safety equipment

functions as intended (for example, that the contact safety switch switches the heating off when the lid is opened).

Before starting production each time, check the furnace for obvious damage and ensure that

it is operated only in a perfect condition. Report any defects to Nabertherm Service

immediately.

19

Before starting production each time, remove all materials and objects that are not needed

for production from the working area.

At least once every day (see also Servicing and Maintenance) check the following:

Check the furnace for obvious external damage (visual check), for example insulation,

heating elements, power cable, exhaust gas system, if applicable.

Check that all safety equipment is functioning (for example, that the contact safety

switch switches the heating off when the door is opened).

Warning! General Hazards!

Risk of burning on the furnace housing

The door handle/grip can become very hot during operation; wear gloves.

Risk of crushing on moving parts (door hinge)

The switchgear cabinet (if present) and the terminal boxes on the system contain dangerous

electrical voltages.

Do not insert any objects into the openings on the furnace housing, exhaust air holes, or

cooling slots on the switchgear or furnace (if present). This poses a risk of electric shock.

Fire hazard if an extension cable is used:

25

With 230 V furnace models make sure that:

The distance between the circuit breaker and the power socket that the furnace is connected

to is as short as possible.

NO power board or extension cable is used between the power socket and the furnace.

Warning – Influence on implants from electromagnetic fields

It can be assumed that there is no risk from electromagnetic fields. Deviating from this,

there may be a risk for people with active implants (such as a pacemaker, insulin pump) and

passive implants, as the function of the implant may be affected also with a field strength

below the permissible threshold. Proper function must be ensured on the basis of the

technical specifications of the implant through an individual assessment by a suitable expert

(for example, an occupational physician).

DANGER

• Danger from electrocution

• If there is no earth connection, or the

earth connection is poorly connected, the

result may be a deadly electrical shock.

• Do not insert any metallic objects such as thermocouples, sensors or tools into the

furnace chamber without having previously

ensured that the plant has been correctly

earthed. Entrust the job of making a earth

connection between the object and the

furnace housing to a qualified electrical

technician. Any objects inserted into the

furnace must be inserted only through those

openings intended for this purpose.

Immediately notify the carrier and Nabertherm GmbH of any missing or damaged parts, as

complaints at a later date cannot be acknowledged.

Danger of Injury

When the furnace is being lifted, parts of the furnace or the furnace itself could topple over,

slip, or fall. Before the furnace is lifted, make sure no one is in the working area. Wear

safety footwear and a hard hat.

Safety Instructions

Forklifts must be operated only by authorized personnel. The operator bears sole

responsibility for safe operation and the load.

When the furnace is being lifted, make sure that the ends of the forks or the load do

not catch on neighboring goods. Use a crane to move tall parts, such as control

cabinets.

Use only lifting equipment with sufficient load-bearing capacity.

Lifting gear must be attached only to positions that have been designated for this

purpose.

Attachments, piping, or cable conduits must never be used to affix lifting gear.

Unpackaged parts should only be lifted with ropes or straps.

Attach transportation equipment only to positions intended for this purpose.

Lifting and securing equipment must conform to the provisions contained in accident

prevention regulations.

Consider the weight of the furnace when choosing lifting and securing equipment. (see Specifications)

Stainless steel parts (including mounting elements) must always be kept separate from

unalloyed steel parts.

Do not remove corrosion protection until immediately prior to assembly.

27

Risks during Normal Operation!

Symbols:

The international standard symbols for handling packaging are defined in ISO R/780

(International Organization for Standardization) and in DIN 55 402 (German

Institute for Standardization).

Description Symbol Explanation

Fragile

This symbol is to be attached to fragile goods. Goods marked like this are to be handled carefully and must

not be thrown or tied up.

28

Description Symbol Explanation

This side up

The freight must be transported, transshipped, and

stored in such a way that the arrows point upward. The

freight must not be rolled, folded, or stored on edge.

However, the package does not have to be packed on

top of other freight.

Keep dry

Products with this symbol must be protected against

high air moisture, hence, they must be stored under cover. If particularly heavy or bulky packages cannot

be stored in halls or sheds, they must be covered

carefully with a tarpaulin or similar.

Sling here

The symbol shows only where the sling should be

attached, not the method of slinging. If the symbols

are at an equal distance from the middle or center of

gravity of the package, the package hangs straight if the slings are the same length. If this is not the case,

the sling on one side has to be shortened.

Installation Location

The operator is responsible for adequate ventilation by installing the appropriate systems to supply fresh air and to vent exhaust air. If a batch emits gases or vapors,

adequate ventilation of the installation site must be provided as well as a suitable

exhaust air venting system. A suitable vent for combustion exhaust must be supplied

by the customer

Make sure that the heat radiated by the furnace is vented (consult a ventilation expert, if necessary)

Although the furnace is well-insulated, the exterior surfaces of the furnace radiate

heat. If necessary, this heat must be dissipated (a ventilation technician may need to

be consulted). In addition, a minimum clearance (S) of 0.5 m on all sides and 1 m

above the furnace must be maintained to flammable materials. In individual cases,

more space must be chosen in order to match the local conditions. For nonflammable

materials, the minimum side clearance can be reduced to 0.2 m.

The furnace must be protected against weather and caustic atmospheres. Nabertherm

accepts no liability or warranty claim for any corrosion damage as a result of

installation in damp surroundings or for similar reasons. Pos: 133 /TD/ Tr ansp ort _Mo nta ge_I nbet rieb nah me/Er stinb etrie bna hme /Min destsic her heitsa bsta nd zu br enn bar en Mate rialien -LH T 0 3/17 D ( Mod ell 20 15) - G rafik @ 11 9\mo d_1 462 347 835 812 _51. docx @ 46 949 6 @ @ 1

• Mortal danger posed by electrocution through wetness,

suffocation caused by extinguishing gas, etc.

• If automatic extinguishing systems are in place to fight fires and

protect the building, e.g. sprinkler systems, care must be taken

during their planning and installation that no additional hazards are

created, for example by extinguishing a pilot light, mixing hardening oil and extinguishing water, the disablement of

electrical equipment, etc.

We recommend connecting an exhaust air pipe to the furnace to remove the exhaust gases.

For this purpose you can use a commercially available, metal exhaust gas pipe with NW80

to NW120. It must be installed continuously rising and fastened to the wall or ceiling.

Center the pipe over the furnace vent.

The exhaust gas pipe must not be installed with a tight fit to the furnace vent pipe since this

would prevent any bypass effect. This is necessary so that not too much fresh air is sucked

in by the furnace.

We recommend feeding the exhaust air through a flue.

The furnace may be put into operation only by qualified persons and in compliance with the

safety instructions.

Read the section on "Safety". When the furnace is put into operation, the following safety

information must also be observed to prevent serious injury, damage to the furnace, and

damage to other property.

Make sure that the instructions and information in the controller instructions are observed

and followed.

The furnace may be used only for its intended purpose.

Ensure that only authorized persons remain in the working area of the furnace and that no

other persons are put at risk when the furnace is put into operation.

Before starting the furnace for the first time, make sure that all tools, foreign parts, and

transportation securing equipment have been removed.

Activate all safety equipment (power switch, emergency stop button if applicable) before

putting the furnace into operation.

Incorrectly wired connections may destroy electric/electronic components.

35

Observe the special protective measures (e.g. grounding, …) for components that are at

risk.

Faulty connections can cause the furnace to start unexpectedly.

Before you switch on the furnace, make sure that you know what to do in case of faults or

emergencies.

Before starting the furnace for the first time, check the electrical connections and control

displays.

Before placing materials in the furnace, check whether they could harm or destroy the

insulation or the heating elements. Materials that could damage the insulation include:

alkalis, alkaline earths, metal vapors, metal oxides, chlorine compounds, phosphorous

compounds, and halogens.

To generate a protective oxidated layer on the heating elements the furnace must be heated

to below the maximum temperature 100 °C (212 °F) for approx. 5 hours (Example: The

furnace is designed for a maximum temperature of approx. 1750 °C (3182 °F), hence a

temperature of approx. 1650 °C (3002 °F) should be entered on the controller. But this

temperature musst be reached over the full period of five hours).

The entered temperature (example: 1650 °C (3002 °F)) should be held for approx. 5 hours.

This process should be executed during the start-up, after replacing the heating elements or

to regenerate the oxide layer.

When the furnace is heated up for the first time, annoying odors may result, these are do to

the escape of binding agents from the insulation material. We recommend that the furnace

location be well ventilated during the first warm-up phase. Let the furnace cool down

naturally to room temperature.

Furnaces heated with molybdenum disilicide elements (MoSi2) are available for max.

furnace chamber temperatures of 1600, 1750 and 1800 °C. The max. furnace chamber

temperature refers to operation in air. At temperatures of over 800 °C, a layer of silicon

oxide occurs on the surface of the heating element, protecting it against further oxidation.

Such a protective layer is not formed at low temperatures. If the surface of the element is not protected, molybdenum and silicon oxidation can take place at temperatures of around

550 °C. This leads to the occurrence of a yellowish powder consisting primarily of

molybdenum oxide (MoO3). This chemical reaction has no disadvantageous effects on the

performance of the heating element.

In an oxidizing atmosphere, the majority of metals form scale on the surface (oxide formation occurs due to a thermal influence in an oxidizing atmosphere). This metal oxide

may react with the silicon oxide of the heating element and shorten its service life. If the

36

furnace is used to melt metals, it must be ensured that the furnace chamber is protected

against metal splashes, soiling and vapors which occur during the melting process

(particularly due to fluxing agents). Metal oxides also strongly corrode the insulation of the

If glass is melted, the furnace atmosphere contains contaminants, the composition of which depends on the relevant glass product. These components usually act as a fluxing agent on

the silicon oxide layer. As a result, its viscosity is reduced and the silicon oxide flows

slowly down the heating element. However, new silicon oxide is immediately formed

again, with the result that the service life is not noticeably shortened. The insulation may

also be severely corroded depending on the type of glass.

Note

When the fresh air lever is opened fresh air is guided in the furnace chamber for drying or

forced cooling. Please make sure that the fresh air lever is closed after drying in order to

achieve a good temperature uniformity during sintering.

The application notes of the zirconia manufacturer should be generally taken into

consideration in order to avoid damages at the charge e.g. due to fast cooling times.

When charging the furnace it must be ensured that the lower charge carrier is generally resting on the spacer ring. This provides for air-circulation under this carrier and improves

the temperature uniformity. It is recommended to cover upper saggar with another sintering

dish as lid. Pos: 212 /TD/B etrie b_Bedi enu ng/ Zum Schutz des Ofen bod en_Dist anz ring - LH T 03 /17 D - Text -Gr afik @ 46\ mod_ 137 778 317 201 4_5 1.doc x @ 2 436 90 @ @ 1

For the protection of the sensitive furnace floor we

recommend that you make it a

general rule to leave the lowest

spacer ring in the furnace. The

spacer ring must be positioned

in the middle of the floor. This

ensures uniform heating of the

charge. When setting

down/lifting the sintering

dishes/spacer rings, they must

always be raised slightly to prevent any unwanted sideways movement of the sintering dishes/spacer rings.

Cleaning, lubrication, and maintenance tasks may only be performed by authorized experts

following the maintenance instructions and accident protection guidelines. We recommend

that maintenance and repair be performed by Nabertherm GmbH Service. Failure to comply

runs the risk of bodily injury, death, or significant property damage!

Warning - Danger due to Electrical Current!

Work on the electrical equipment may only be performed by qualified, authorized

electricians!

During maintenance work, the voltage supply to the furnace and/or switching system must

be switched off to prevent unintentional commissioning. Disconnect the mains power

connector due to reasons of safety.

Operators may only correct malfunctions which are obviously due to operational error!

Wait until the furnace chamber and attaching parts have cooled to room temperature.

The furnace must be visually inspected at regular intervals for damage. The interior of the

furnace must also be cleaned as required (e.g. vacuuming out) Attention: Do not bang

against the heating elements to avoid breaking them.

While work is being performed on the furnace, the furnace and work room must additionally be ventilated with fresh air.

Safety systems removed during maintenance tasks must be replaced after the work.

Warning of swinging loads in the workshop (e.g. crane systems). Work under a lifted load

(e.g. a lifted furnace or switching system) is not permitted.

Safety switches and any limit switches present must be checked for function periodically

(DGUV V3) or according to the national guidelines of the country of operation.

To ensure proper temperature regulation of the furnace, the thermocouple must be checked

for damage before every process.

If necessary, retighten the element holders (see chapter "Replacing the Heating Element").

Before carrying out this work, the voltage supply to the furnace and/or switching system

must be switched off (disconnect mains power connector). The regulations (DGUV V3) or

corresponding national regulations in the relevant country of operation must be observed.

There are one or more contactors in the control system. The contacts of these circuit

breakers are wearing parts and must therefore be serviced and/or replaced regularly

(DGUV V3) or according to the national guidelines of the country of operation.

The switching system cabinet (if available) contains vent grilles with integrated filter mats.

These must be cleaned and/or replaced at regular intervals in order to ensure sufficient

45

intake and outflow of air from the switching system. During melting operation, the

switching cabinet door must always be firmly closed.

When repairs are made or demolition work is performed, silicon dust may be released.

Depending heat-treated materials contained in the furnace, further contaminants may be contained in the insulation. To exclude possible health risks, dust concentrations must be

kept to a minimum during any work performed at or near the insulation. In many countries

there are specific occupational safety limits. You can acquire more relevant information by

investigating the relevant legal specifications in your country.

Dust concentrations should be kept as low as possible. Dust must be removed using a suction device or a vacuum cleaner with a high-performance filter (HEPA – category H).

Strong air currents such as drafts, for example, must be prevented. Pressurized air or brush

must not be used for cleaning. Piles of dust must be sprinkled. Pos: 232 /TD/Allg em eine Hinw eise (fü r alle Anl eitun gen )/Isoli eru ng (kF )_Bei Arb eite n an de r Isolie run g sollt e ein At emsc hutz mit FFP2 ... - Teil 3 @ 86\ mod _14 258 994 437 68_5 1.d ocx @ 366 364 @ @ 1

During work on the insulation a respirator mask with an FFP2 filter or an FFP3 filter must

Monitoring

04-01 No heat output No temperature increase in

does not equal 100% for 12

minutes and if the temperature

setpoint is greater than the current furnace temperature

Acknowledge the error (deenergize if necessary)

and check the safety contactor, door switch,

heating control and controller.

04-02 Over-temperature The temperature of the guide

zone exceeds the max. program

setpoint or the maximum furnace temperature by 50°

Kelvin (200 °C or higher)

The equation for the shutdown

threshold is:

maximum program setpoint +

zone offset of the master zone +

batch control offset [max] (if

batch control is active) + over-

temperature shutdown threshold

(P0268, e.g. 50 K)

Check the solid state relay

Check the thermocouple

Check the controller

A program has started at a

furnace temperature that is

greater than the maximum

setpoint in the program

Wait until the temperature of the furnace has

dropped before starting the program.

If this is not possible, add a wait time as a start

segment, followed by a ramp with the desired

temperature (STEP = 0 minute duration for both

segments)

Example:

700 °C -> 700 °C, time: 00:00

700 °C -> 300 °C, time: 00:00

The normal program then starts here.

In version 1.14 and later, the actual temperature is

also taken into account at the start.

The temperature rises

faster than the controller

setting allows

The switch element of the heating unit

(semiconductor relay, thyristor or switch contactor) is defective.

Individual defective components inside a

furnace cannot be completely ruled out in

advance. That is why the controllers and the

switchgear units must be equipped with

safety facilities. For example, the furnace shuts down the heating unit in response to

error message 04 - 02 via an independent

contact element.

Have the switch element tested by a

qualified electrician and replaced as necessary.

The gas supply system must be inspected to ensure it is in perfect condition before each use. If a defect is discovered the furnace must be shut down immediately.

During operation toxic gases and vapors can be released. They must be appropriately

vented out of the building. Ignoring this warning can be dangerous to your health.

Only use gases whose characteristics are known. If something unexpected happens in the

furnace (for example, build up of dense smoke or noxious smells) it must be shut down

immediately and you must wait until the furnace has cooled down naturally.

74

The use of the gas supply system in connection with combustible gases is only permissible

with additional "safety devices".

You must ensure that the installation room is well ventilated and that protective gas

emissions do not present any danger.

It is the user's responsibility to ensure compatibility with local safety and installation

regulations.

The use of the furnace for the purposes for which is was designed also requires

observing the instructions contained in this operating manual for installation, start-up

and maintenance.

You must be aware of the real or potential combustibility and explosiveness of gases when they are when operating the furnace. Make sure in particular that no corrosive or

health endangering substances are generated and escape into the surrounding air.

Operating the system is prohibited with power sources, products, operating

equipment, auxiliary materials, etc., which are listed as hazardous or which may in

any way harm the health of the personnel operating the furnace.

Make sure the hose connection is perfectly tight before each use.

The gas supply system must be checked for leaks and deposits in the flow meter (use a

leak detection spray if necessary).

The functionality of the ball valve and the solenoid valve must be checked at regular

intervals.

Warning - Danger of Suffocation

There is a danger of suffocation when process/purge or exhaust gases escape, e.g. as a

results of leaks (e.g. at doors, pipes, valves, etc.).

Due to their specific weight gases can displace oxygen. This poses a danger of suffocation.

Measures: Switch on the extraction system.

Compressed gas containers may be operated only by persons familiar with their handling. Before performing their duties, employees must be respectively instructed

in the operation of the compressed gas containers,

on the special hazards of handling compressed gas containers and

on the actions to be taken in case of accidents or malfunctions. This instruction must be

repeated at appropriate intervals.

Compressed gas bottles may be stood up in work rooms only in the absolutely necessary

quantities and in the smallest possible sizes, and only for immediate use.

Storage of compressed gas bottles in work rooms is impermissible.

Gas bottles should be kept in suctioned gas bottle cabinets if possible.

When no gas is being taken, always keep the main valve on the gas bottle closed. Gas

bottles without screwed-on pressure reducers must not be stood up without protective caps. Gas hoses must be regularly checked for fractured or porous areas and if necessary

immediately replaced.

Safety measures and appropriate conduct

Secure compressed gas containers against falling over, against jarring, shock and

heating (e.g. from heater or furnace system).

At the workplace only keep ready the number of compressed gas bottles required for

continuing the work.

Transport only with bottle transport vehicles and with protective caps firmly screwed

on.

Wear suitable gloves and if necessary goggles.

When changing bottles always check leaktightness of the valves of filled and empty

bottles.

Refilling bottles is prohibited.

Do not use force to open valves.

Sufficiently ventilate areas.

Smoking and open flames are prohibited.

Keep fire extinguisher ready.

The operator must produce operating instructions stating the hazards occurring in the

work room for people and the environment as well as stating the generally required

protective measures and rules of conduct. The operating instructions must be written

in an understandable form and kept available in the work room. The operating

instructions must also contain instructions on conduct in case of danger and on first-

aid measures.

12.1 Transportation/Return Transportation

If you still have the original packaging, this is the safest way to send a furnace.

Otherwise:

Choose suitable, adequately sturdy packaging. During transportation, packages are often

stacked, bumped, or dropped; the packaging acts as external protection for your furnace.

+45 °

-5 °C

- Drain all piping and containers before transportation/return transportation

(e.g. cooling water). Pump off operating materials and dispose of properly.

- Do not subject the furnace to extreme cold or hot temperatures (direct sunlight).

Storage temperature -5 °C to 45 ° (-23 °F to 113 °F)

Humidity 5 % to 80 %, non condensing

- Place the furnace on a level floor to prevent distortion.

- Packaging and transportation may be carried out only by qualified and

authorized persons

If your furnace has transportation securing equipment (see "Transportation Securing

Equipment"), use this.

79

Otherwise, in general:

"Fix" and "secure" (adhesive tape) all moving parts and cushion and protect any projecting

parts against breakage.

Protect your electronic equipment against moisture and make sure that no loose packaging

material can get inside it.

Fill gaps in your packaging with soft but adequately firm material (e.g. foam mats) and

make sure that the equipment cannot slide around in the packaging.

If the goods are damaged during return transportation due to inadequate packaging

or some other breach of duty, the costs will be borne by the customer.

As a rule:

The furnace is sent without accessories, unless the technician expressly requests them.

Enclose a detailed description of the malfunction along with the furnace – this saves the

technician time and costs.

Don't forget to enclose the name and phone number of a contact in case there are any

questions.

Note

Return transportation may only be carried out according to the information given on the

packaging or in the transportation documents.

Note

Transportation and return transportation not covered by a warranty claim are paid for by

the customer.
