SAFETY PRECAUTIONS
The precautions listed here are divided into the following four types.They all cover very important topics, so be sure to follow themcarefully.
■ After completing installation, test the unit to check for installationerrors. Give the user adequate instructions concerning the useand cleaning of the unit as included in the operation manual ofthe indoor unit.
Danger■ Before touching electric terminal parts, turn off power switch.
■ When service panels are removed, live parts can be easilytouched by accident.
Never leave the unit unattended during installation or servicingwhen the service panel is removed.
■ Do not touch water pipes during and immediately after operationas the pipes may be hot. Your hand may suffer burns. To avoidinjury, give the piping time to return to normal temperature or besure to wear proper gloves.
Warning■ Ask your dealer or qualified personnel to carry out installation work.
Do not install the machine by yourself.Improper installation may result in water leakage, electric shocksor fire.
■ Perform installation work in accordance with this installationmanual.Improper installation may lead to water leakage, electric shocksor fire.
■ Consult your local dealer regarding what to do in case ofrefrigerant leakage. When the unit is to be installed in a smallroom, it is necessary to take proper measures so that theamount of any leaked refrigerant does not exceed theconcentration limit in the event of a leakage. Otherwise, this maylead to an accident due to oxygen depletion.
■ Be sure to use only the specified accessories and parts forinstallation work.Failure to use the specified parts may result in water leakage,electric shocks, fire, or the unit falling.
■ Install the unit on a foundation that can withstand its weight.Insufficient strength may result in the fall of equipment andcausing injury.

Installation manual
1
■ Carry out the specified installation work in consideration of strongwinds, typhoons, or earthquakes.Improper installation work may result in accidents due to fall ofequipment.
■ Make certain that all electrical work is carried out by qualifiedpersonnel according to the local laws and regulations and thisinstallation manual, using a separate circuit.Insufficient capacity of the power supply circuit or improperelectrical construction may lead to electric shocks or fire.
■ Make sure that all wiring is secure, using the specified wires andensuring that external forces do not act on the terminalconnections or wires.Incomplete connection or fixing may cause a fire.
■ When wiring between the indoor and outdoor units, and wiringthe power supply, form the wires so that the side panel can besecurely fastened. Install covers over the wires.If the side panel is not in place, overheat of the terminals,electric shocks or a fire may be caused.
■ If refrigerant gas leaks during installation work, ventilate thearea immediately.Toxic gas may be produced if refrigerant gas comes into contactwith fire.
■ Do not touch the refrigerant pipes during and immediately afteroperation as the refrigerant pipes may be hot or cold, dependingon the condition of the refrigerant flowing through the refrigerantpiping, compressor, and other refrigerant cycle parts. Yourhands may suffer burns or frostbite if you touch the refrigerantpipes. To avoid injury, give the pipes time to return to normaltemperature or, if you must touch them, be sure to wear propergloves.
■ After completing the installation work, check to make sure thatthere is no leakage of refrigerant gas.Toxic gas may be produced if refrigerant gas leaks into the roomand comes into contact with a source of fire, such as a fanheater, stove or cooker.
■ When planning to relocate former installed units, you must firstrecover the refrigerant after the pump down operation. Refer tochapter "Pump down operation" on page 10.
■ Never directly touch any accidental leaking refrigerant. Thiscould result in severe wounds caused by frostbite.
■ Be sure to install an earth leakage circuit breaker in accordancewith relevant local and national regulations. Failure to do so maycause electrical shock and fire.
■ Electrical work must be carried out in accordance with theinstallation manual and the national electrical wiring rules orcode of practice.Insufficient capacity or incomplete electrical work may causeelectrical shock or fire.
■ Be sure to use a dedicated power circuit. Never use a powercircuit shared by another appliance.
■ For wiring, use a cable long enough to cover the entire distancewith no connection. Do not use an extension cord. Do not putother loads on the power supply, use a dedicated power circuit.Failure to do so may cause abnormal heat, electric shock, or fire.
■ During pump down operation, stop the compressor beforeremoving the refrigerant piping.If the compressor is still running and the stop valve is openduring pump-down, air will be sucked in when the refrigerantpiping is removed, causing abnormal pressure in the freezercycle which will lead to breakage and even to injury.
■ During installation, attach the refrigerant piping securely beforerunning the compressor.If the compressor is not attached and the stop valve is openduring pump-down, air will be sucked in when the compressor isrunning, causing abnormal pressure in the freezer cycle whichwill lead to breakage and even to injury.
Caution■ Earth the unit.
Earthing resistance should be according to national regulationsDo not connect the earth wire to gas or water pipes,lightning conductor or telephone earth wire.Incomplete earthing may cause electric shocks.
■ Gas pipe.Ignition or explosion may occur if the gas leaks.
■ Water pipe.Hard vinyl tubes are not effective earths.
■ Lightning conductor or telephone earth wire.Electric potential may rise abnormally if struck by a lightningbolt.
■ Install drain piping according to this installation manual toensure good drainage, and insulate the pipe to preventcondensation. See combination table in "Possible options" onpage 3.Improper drain piping may cause water leakage, and make thefurnitures get wet.
■ Install the indoor and outdoor units, power wire and connectingwire at least 1 meter away from televisions or radios to preventimage interference or noise.(Depending on the radio waves, a distance of 1 meter may notbe sufficient to eliminate the noise.)
■ Do not rinse the outdoor unit. This may cause electric shocks orfire.
■ Do not install the unit in places such as the following:
■ Where there is mist of mineral oil, oil spray or vapour forexample a kitchen.Plastic parts may deteriorate, and cause them to fall out orwater to leak.
■ Where corrosive gas, such as sulphurous acid gas, isproduced.Corrosion of copper pipes or soldered parts may cause therefrigerant to leak.
■ Where there is machinery which emits electromagneticwaves.Electromagnetic waves may disturb the control system, andcause malfunction of the equipment.
■ Where flammable gases may leak, where carbon fiber orignitable dust is suspended in the air or where volatileflammables, such as thinner or gasoline, are handled.Such gases may cause a fire.
■ Where the air contains high levels of salt such as that nearthe ocean.
■ Where voltage fluctuates a lot, such as that in factories.
■ In vehicles or vessels.
■ Where acidic or alkaline vapour is present.
■ Do not allow a child to mount on the outdoor unit or avoidplacing any object on the unit. Falling or tumbling may result ininjury.
■ For use of units in applications with temperature alarm settings itis advised to foresee a delay of 10 minutes for signalling thealarm in case the alarm temperature is exceeded. The unit maystop for several minutes during normal operation for "defrostingthe unit", or when in "thermosta-stop" operation.
■ Tighten the flare nut according to the specified method such aswith a torque wrench.If the flare nut is tightened too hard, the flare nut may crack aftera long time and cause refrigerant leakage.

INSTALLATION GUIDELINES
Precautions for selecting the location
■ The equipment is not intended for use in a potentially explosiveatmosphere.
■ Choose a place solid enough to bear the weight and vibration ofthe unit, where the operation noise will not be amplified.
■ Choose a location where the hot air discharged from the unit orthe operation noise will not cause a nuisance to the neighboursof the user.
■ Avoid places near a bedroom and the like, so that the operationnoise will cause no trouble.
■ There must be sufficient space for carrying the unit into and outof the site.
■ There must be sufficient space for air passage and noobstructions around the air inlet and the air outlet.
■ The site must be free from the possibility of flammable gasleakage in a nearby place.
■ Locate the unit so that the noise and the discharged hot air willnot annoy the neighbours.
■ Install units, power cords and inter-unit cables at least 3 m awayfrom television and radio sets. This is to prevent interference toimages and sounds.
■ Depending on radio wave conditions, electromagneticinterference may still occur even if installed more than 3 m away.
■ In coastal areas or other places with salty atmosphere of sulfategas, corrosion may shorten the life of the outdoor unit.
■ Since drain flows out of the outdoor unit, do not place anythingunder the unit which must be kept away from moisture.
1 Select an installation site where the following conditions aresatisfied and that meets with your customer's approval.
- Places which are well-ventilated.- Places where the unit does not bother next-door neighbours.- Safe places which can withstand the unit's weight and
vibration and where the unit can be installed level.- Places where there is no possibility of flammable gas or
product leak.- The equipment is not intended for use in a potentially
explosive atmosphere.- Places where servicing space can be well ensured.- Places where the indoor and outdoor units' piping and wiring
lengths come within the allowable ranges.- Places where water leaking from the unit cannot cause
damage to the location (e.g. in case of a blocked drain pipe).- Places where the rain can be avoided as much as possible.- Do not install the unit in places often used as work place.
In case of construction works (e.g. grinding works) where alot of dust is created, the unit must be covered.
- Do not place any objects or equipment on top of the unit (top plate).
- Do not climb, sit or stand on top of the unit,- Be sure that sufficient precautions are taken, in accordance
with relevant local and national regulations, in case of refrigerant leakage.
2 When installing the unit in a place exposed to strong wind, payspecial attention to the following.
Strong winds of 5 m/sec or more blowing against the outdoorunit's air outlet causes short circuit (suction of discharge air),and this may have the following consequences:- Deterioration of the operational capacity.- Frequent frost acceleration in heating operation.- Disruption of operation due to rise of high pressure.- When a strong wind blows continuously on the face of the
unit, the fan can start rotating very fast until it breaks.Refer to the figures for installation of this unit in a place wherethe wind direction can be foreseen.
3 Prepare a water drainage channel around the foundation, todrain waste water from around the unit.
4 If the water drainage of the unit is not easy, please build up theunit on a foundation of concrete blocks, etc. (the height of thefoundation should be maximum 150 mm).
5 If you install the unit on a frame, please install a waterproof platewithin 150 mm of the underside of the unit in order to prevent theinvasion of water from the lower direction.
NOTE ■ An ERLQ0*BA outdoor unit can only beconnected to an EKHBH/X008BA indoor unit(bottom plate heater at outdoor unit has to becontrolled by indoor unit).
■ An ERHQ0*BA outdoor unit can be connected toan EKHBH/X008BA indoor unit or to anEKHBH/X008AA indoor unit (if a bottom plateheater kit is required, see "Possible options" onpage 3).

Selection of copper and heat insulation materials
When using commercial copper pipes and fittings, observe thefollowing:
■ Insulation material: polyethylene foamHeat transfer rate: 0.041 to 0.052 W/mK (0.035 to 0.045kcal/mh°C)Refrigerant gas pipe's surface temperature reaches 110°C max.Choose heat insulation materials that will withstand thistemperature.
■ Be sure to insulate both the gas and liquid piping and to provideinsulation dimensions as below.
■ Use separate thermal insulation pipes for gas and liquidrefrigerant pipes.
Purging air and checking gas leakage
When all piping work is completed and the outdoor unit is connectedto the indoor unit, it is necessary to purge the air and check for gasleakage.
■ If using additional refrigerant, perform air purging from therefrigerant pipes and indoor unit using a vacuum pump, thencharge additional refrigerant.
■ Use a hexagonal wrench (4 mm) to operate the stop valve rod.
All field piping must be installed by a licensed refrigerationtechnician and must comply with relevant local andnational regulations.
CAUTION
■ Do not use mineral oil on flared part.Mineral oil getting into the system would reduce thelifetime of the units.
■ Never use piping which has been used for previousinstallations. Only use parts which are delivered withthe unit.
■ Do never install a drier to this R410A unit in order toguarantee its lifetime. The drying material maydissolve and damage the system.
■ Incomplete flaring may cause refrigerant gas leakage.

Charging additional refrigerant
If the total length of refrigerant piping exceeds 10 m in length,additionally charge with 20 g of refrigerant (R410A) for eachadditional meter of piping.
Determine the weight of refrigerant to be charged additionally and fillin the amount in the service sticker on the rear side of the stop valvecover.
Precautions when adding R410A■ Be sure to charge the specified amount of refrigerant in liquid
state to the liquid pipe.Since this refrigerant is a mixed refrigerant, adding it in gas formmay cause the refrigerant composition to change, preventingnormal operation.
■ Before charging, check whether the refrigerant cylinder isequipped with a siphon tube or not (the cylinder should bemarked with "liquid filling siphon attached" or something similar).
■ Be sure to use tools exclusively for R410A to ensure requiredpressure resistance and to prevent foreign materials from mixinginto the system.
Wiring
Equipment complying with EN/IEC 61000-3-12(1)
Charge the liquid refrigerant with the cylinder in upright position.
Charge the liquid refrigerant with the cylinder in up-side-down position.
DANGER
■ Before obtaining access to terminal devices, all supplycircuits must be interrupted.
■ High voltageTo avoid electrical shock, make sure to disconnect thepower supply 1 minute or more before servicing theelectrical parts. Even after 1 minute, always measurethe voltage at the terminals of main circuit capacitorsor electrical parts and, before touching, make surethat those voltages are 50 V DC or less.
To persons in charge of electrical wiring work:
Do not operate the unit until the refrigerant piping iscomplete. (Running it before the piping is ready will breakthe compressor.)
