1 Important information

Safety precautions

CautionInstall the system in full accordance with this installationmanual.Incorrect installation can cause bursts, personal injury, water leaks,refrigerant leaks, electric shocks and fire.

Observe the measurement values before working on thecooling system, especially when installing in small rooms, sothat the limit for the refrigerant's density is not exceeded.Consult an expert to interpret the measurement values. If the refri-gerant density exceeds the limit, lack of oxygen can occur in theevent of any leak, which can cause serious accidents.

Use original accessories and the stated components for theinstallation.If parts other than those stated by us are used, water leaks, electricshocks, fire and personal injury may occur as the unit may not workproperly.

Ventilate theworking areawell – refrigerant leakagemayoccurduring service work.If the refrigerant comes into contact with naked flames, poisonousgas is created.

Install the unit in a location with good support.Unsuitable installation locations can cause the unit to fall and causematerial damage and personal injury. Installation without sufficientsupport can also cause vibrations and noise.

Ensure that the unit is stable when installed, so that it canwithstand earthquakes and strong winds.Unsuitable installation locations can cause the unit to fall and causematerial damage and personal injury.

The electrical installation must be carried out by a qualifiedelectrician and the system must be connected as a separatecircuit.Power supply with insufficient capacity and incorrect function cancause electric shocks and fire.

Use the stated cables for the electrical connection, tighten thecables securely in the terminal blocks and relieve the wiringcorrectly to prevent overloading the terminal blocks.Loose connections or cable mountings can cause abnormal heatproduction or fire.

Check, after completed installation or service, that no refriger-ant leaks from the system in gas form.If refrigerant gas leaks into the house and comes into contact withan aerotemp, an oven or other hot surface, poisonous gases areproduced.

Use types of pipe and tools stated for this type of refrigerant.Using existing parts for other refrigerants can cause breakdownsand serious accidents due to process circuit bursts.

Switch off the compressor before opening/breaching the refri-gerant circuit.If the refrigerant circuit is breached /opened whilst the compressoris running, air can enter the process circuit. This can cause unusuallyhigh pressure in the process circuit, which can cause bursts andpersonal injury.

Switch off the power supply in the event of a service or inspec-tion.If the power supply is not shut off, there is a risk of electric shocksand damage due to the rotating fan.

Do not run the unit with removed panels or protection.Touching rotating equipment, hot surfaces or high voltage partscan cause personal injury due to entrapment, burns or electricshocks.

Cut the power before starting electrical work.Failure to cut the power can cause electric shocks, damage and in-correct function of the equipment.

CareCarry out the electrical installation with care.Do not connect the ground lead to the gas line, water line, lightningconductor or telephone line's ground lead. Incorrect groundingcan cause unit faults such as electric shocks due to short-circuiting.

Use main switch with sufficient breaking capacity.If the switch does not have sufficient breaking capacity, malfunc-tions and fire can occur.

Always use a fusewith the correct rating in the locationswherefuses are to be used.Connecting the unit with copper wire or other metal thread cancause unit breakdown and fire.

Cables must be routed so that they are not damaged bymetaledges or trapped by panels.Incorrect installation can cause electric shocks, heat generationand fire.

Do not install the unit in close proximity to locations whereleakage of combustible gases can occur.If leaking gases collect around the unit, fire may occur.

Donot install the unitwhere corrosive gas (for example nitrousfumes) or combustible gas or steam (for example thinner andpetroleum gases) can build up or collect, or where volatilecombustible substances are handled.Corrosive gas can cause corrosion to the heat exchanger, breaksin plastic parts etc. and combustible gas or steam can cause fire.

Do not use the unit for specialist purposes such as for storingfood, cooling precision instruments, freeze-conservation ofanimals, plants or art.This can damage the items.

Do not install and use the system close to equipment thatgenerates electromagnetic fields or high frequency harmonics.Equipment such as inverters, standby sets, medical high frequencyequipment and telecommunications equipment can affect the unitand cause malfunctions and breakdowns. The unit can also affectmedical equipment and telecommunications equipment, so thatit functions incorrectly or not at all.

Take care when carrying the unit by hand.If the unit weights more than 20 kg, it must be carried by twopeople. Use gloves to minimize the risk of cuts.

Dispose of any packaging material correctly.Any remaining packaging material can cause personal injury as itmay contain nails and wood.

Do not touch any buttons with wet hands.This can cause electric shocks.

Do not touch any refrigerant pipes with your hands when thesystem is in operation.During operation the pipes become extremely hot or extremelycold, depending on the method of operation. This can cause burninjuries or frost injuries.

Donot shut off the power supply immediately after operationhas start.Wait at least 5 minutes, otherwise there is a risk of water leakageor breakdown.

Do not control the system with the main switch.This can cause fire or water leakage. In addition, the fan can startunexpectedly, which can cause personal injury.

5Chapter 1 | Important informationNIBE F1345

Especially for units intended for R407C andR410A- Do not use other refrigerants that those intended for the unit.

- Do not use charging bottles. These types of bottles change thecomposition of the refrigerant, which makes the performance ofthe system worse.

- When filling refrigerant, the refrigerant must always leave thebottle in liquid form.

- R410A means that the pressure is about 1.6 times as high as forconventional refrigerants.

- The filling connections on units with R410A are different sizes, toprevent the system being filled with the incorrect refrigerant bymistake.

Serial numberThe serial number can be found at the bottom right ofthe front cover, on the type plate PF1, (see chapter HeatPump Design for location) and in the info menu (menu3.1).

Serial number

Caution

Always give the product's serial number (14 di-gits) when reporting a fault.

RecoveryLeave the disposal of the packaging to the in-staller who installed the product or to specialwaste stations.

Do not dispose of used products with normalhousehold waste. It must be disposed of at a

special waste station or dealer who provides this type ofservice.

Improper disposal of the product by the user results inadministrative penalties in accordance with current legis-lation.

Lift from the street to the set up locationIf the base allows, the simplest thing is to use a pallettruck to move the F1345 to the set up location.

NOTE

The centre of gravity is offset to one side (seeprint on the packaging).

F1345 must be lifted on the heaviest side and can bemoved on a sack truck. Two people are required to liftF1345.

Lift from the pallet to final positioningBefore lifting, remove the packaging and the load anchorto the pallet as well as front and side panels.

Before lifting, the heat pump must be separated bypulling the cooling modules out from the cabinet. Seethe service chapter in the operating manual for instruc-tions about the separation.

Carry the heat pump by the upper cooling module's sliderails, use gloves.

NOTE

The heat pump must not be moved when onlythe lower cooling module has been pulled out.If the heat pump is not secured in position theupper cooling module must always be removedbefore the lower one can be pulled out.

ScrappingFor scrapping, remove the product in reverse order.

Assembly■ Position F1345 on a fixed foundation that can take the

weight of the heat pump. Use the product's adjustablefeet to obtain a horizontal and stable set-up.

■ Because water comes from F1345, the area where theheating pump is located must be equipped with floordrainage.

■ Install with its back to an outside wall, ideally in a roomwhere noise does not matter, in order to eliminatenoise problems. If this is not possible, avoid placing itagainst a wall behind a bedroom or other room wherenoise may be a problem.

■ Wherever the unit is located, walls to sound sensitiverooms should be fitted with sound insulation.

■ Route pipes so they are not fixed to an internal wallthat backs on to a bedroom or living room.

Installation areaLeave a free space of 800 mm in front of the product.Approx. 50 mm free space is required on each side, toremove the side panels (see image). The panels do notneed to be removed during service. All service on F1345can be carried out from the front. Leave space betweenthe heat pump and the wall behind (and any routing ofsupply cables and pipes) to reduce the risk of any vibra-tion being propagated.

GeneralPipe installation must be carried out in accordance withcurrent standards and directives. F1345 can operate witha return temperature of up to 58 °C and an outgoingtemperature of 65 °C.

F1345 is not equipped with internal shut off valves; thesemust be installed to facilitate any future servicing.

NOTE

The pipe installations must be flushed beforeF1345 is connected, so that any contaminantsdo not damage the components parts.

NOTE

Do not solder directly on the pipes in F1345,because of internal sensors.

Compression ring coupling alternatively pressureconnection should be used.

NOTE

The heating system's pipes must be earthed toprevent a potential difference between themand the building's protective earth.

System diagramF1345 consists of two heat pump modules, circulationpumps and control system with possibility of additionalheat. F1345 is connected to the brine and heating medi-um circuits.

In the heat pump evaporator, the brine (water mixedwith anti-freeze, glycol or ethanol) releases its energy tothe refrigerant, which is vaporised in order to be com-pressed in the compressor. The refrigerant, of which thetemperature has now been raised, is passed to the con-denser where it gives off its energy to the heating medi-um circuit and, if necessary, to any docked water heater.If there is a greater need for heating/hot water than thecompressors can provide it is possible is to connect anexternal immersion heater.

Applies to PEM hose 40x2.4 PN 6.3.

These are rough example values. At installation the cor-rect calculations must be made according to local condi-tions.

Caution

The length of the collector hose varies depend-ing on the rock/soil conditions, climate zoneand on the climate system (radiators or under-floor heating).

Max length per coil for the collector should not exceed500 m.

The collectors must always be connected in parallel withthe possibility of adjusting the flow for the relevant coil.

For surface soil heat, the hose should be buried at adepth determined by local conditions and the distancebetween the hoses should be at least 1 metre.

For several bore holes, the distance between the holesmust be determined according to local conditions.

Ensure the collector hose rises constantly towards theheat pump to avoid air pockets. If this is not possible,airvents should be used.

Because the temperature of the brine system may fallbelow 0 °C, it must be protected against freezing downto -15 °C. When making the volume calculation, 1 litreof ready mixed brine per meter of collector hose (applieswhen using PEM-hose 40x2.4 PN 6.3) is used as a guidevalue.

Caution

Because the temperature of the brine systemvaries depending on the heat source, the 5.1.7“br pmp al set.” menu must be set to a suitablevalue.

Connecting the brine side■ The pipe connections are on the rear of the heat pump.

■ Insulate all indoor brine pipes against condensation.

NOTE

Condensation may drip from the expansionvessel. Position the vessel so that this does notharm other equipment.

Caution

When necessary you should install ventingvalves in the brine system.

■ Mark the brine system with the antifreeze that is used.

■ Install the supplied safety valve at the expansion vesselas illustrated in the outline diagram. The entire lengthof the overflow water pipe from the safety valves mustbe inclined to prevent water pockets and must also befrost-free.

■ Install shut off valves as close to the heat pump aspossible so that the flow to individual cooling modulescan be shut off. Extra safety valves between the particlefilter and shut off valves (according the outline dia-gram) are required.

■ Fit the supplied particle filter on the incoming pipe.

■ Fit the supplied non-return valves on the outgoingpipe.

In the case of connection to an open groundwater sys-tem, an intermediate frost-protected circuit must beprovided, because of the risk of dirt and freezing in theevaporator. This requires an extra heat exchanger.

The heat pump (EB100) prioritises charging of hot waterwith half the power (cooling module EP14) via a revers-ing valve (EB100-QN10). When the water heater/accu-mulator tank (CP10) is fully charged, (EB100-QN10)switches to the heating circuit. When there is a demandfor heat, cooling module (EP15) starts in heat pump(EB101) first. For greater demand, cooling module (EP14)also starts in (EB101) for heating operation.

Additional heat (EB1) is connected automatically, whenthe energy requirement exceeds the heat pump capacity.

If the water heater/accumulator tank (CP10) is fittedwith a peak heater (EB10) plus accessories board (AA5),the "temporary lux" function can be used.


GeneralAll electrical equipment, except the outdoor sensors,room sensors and the current sensors are already connec-ted at the factory. For 40 and 60 kW the brine pump issupplied (does not apply to all countries, see list of sup-plied items) and must be installed outside the heat pump.■ Disconnect the heat pump before insulation testing

the house wiring.

■ If the building is equipped with an earth-fault breaker,each F1345 should be equipped with a separate one.

■ If a miniature circuit breaker is used this should haveat least motor characteristic “C”. See page 44 for fusesize.

■ Electrical wiring diagram for the heat pump, see page52.

■ Communication and sensor cables to external connec-tions must not be laid close to high current cables.

■ The minimum area of communication and sensorcables to external connections must be 0.5 mm² up to50 m, for example EKKX or LiYY or equivalent.

■ When cable routing in F1345, cable grommets (e.g.UB2, power cables and UB3, signal cables, marked inimage) must be used. Secure the cables in the groovesin the panel using cable ties (see image).

Load monitorWhen many power consumers are connected in theproperty at the same time as the electric additional heatis in operation, there is a risk of the property’s main fusestripping. F1345 has an integrated load monitor thatcontrols the power steps for the electric additional heatby disconnecting step by step in event of overload in aphase. Reconnection occurs when other current consump-tion is reduced.

Connecting current sensors

A current sensor (BE1 - BE3) must be installed on eachincoming phase conductor into the electrical distributionunit, to measure the current. The electrical distributionunit is an appropriate installation point.

Connect the current sensors to a multi-core cable in anenclosure next to the electrical distribution unit. Useunscreened multi-core cable of at least 0.5 mm², fromthe enclosure to F1345.

Connect the cable to terminal block -AA101-X10:15 to-AA101-X10:16 and -AA101-X10:17 as well as to thecommon -AA101-X10:18 terminal block for the threecurrent sensors.

There is an option to change the size of the property'smain fuse and the current sensor's transformer ratio;these are set in menu 5.1.12.

Enclosed current sensors have a transformer ratio of 300and, if these are used, the incoming current must notexceed 50 A.

NOTE

The voltage to the input board must not exceed3.2 V.

Room sensorF1345 can be supplemented with a room sensor (BT50).The room temperature sensor has up to three functions:1. Show current room temperature in the heat pump's

display.2. Option of changing the room temperature in °C.3. Makes it possible to change/stabilise the room

temperature.

Install the sensor in a neutral position where the settemperature is required. A suitable location is on a freeinner wall in a hall approx. 1.5 m above the floor. It isimportant that the sensor is not obstructed from meas-uring the correct room temperature by being located,for example, in a recess, between shelves, behind a cur-tain, above or close to a heat source, in a draft from anexternal door or in direct sunlight. Closed radiator ther-mostats can also cause problems.

F1345 operates without the sensor, but if you want toread off the home’s indoor temperature in the display,the sensor must be installed. Connect the room sensorto -AA3-X6:3 and -AA3-X6:4.

If the sensor is to be used to change the room temperat-ure in °C and/or to change/stabilise the room temperat-ure, the sensor must be activated in menu 1.9.4.

If the room sensor is used in a room with under floorheating it should only have an indicatory function, notcontrol of the room temperature.

Step controlled additional heat

NOTE


External step-controlled additional heat can be con-trolled by up to three potential-free relays in F1345 (3step linear or 7 step binary). With the AXC 50 accessory,a further three potential-free relays are used for addition-al heat control, which then gives max 3+3 linear or 7+7binary steps.

Step in occurs with at least 1 minute interval and stepouts with at least 3 seconds interval.

Connect the common phase to terminal block -AA101-X7:1.

Step 1 is connected to terminal block -AA101-X7:2.



The settings for step controlled additional heat are madein menu 4.9.3 and menu 5.1.12.

All additional heat can be blocked by connecting a po-tential-free switch function to AUX input on terminalblock -AA3-X6 and -AA101-X10. The function must beactivated in menu 5.4.

Shunt controlled additional heat

NOTE


This connection enables an external additional heater,e.g. an oil boiler, gas boiler or district heating exchangerto aid with heating.

The connection requires that the boiler sensor (BT52) isconnected to one of the AUX inputs in F1345, see section“External connection options (AUX)” on page 31. Thesensor is only selectable when “shunt controlled add.heat” is selected in menu 5.1.12.

F1345 controls a shunt valve and start signal to the addi-tional heating using three relays. If the installation doesnot manage to keep the correct supply temperature, theadditional heat starts. When the boiler sensor (BT52)displays approx. 55 °C, the F1345 transmits a signal tothe shunt (QN11) to turn on the additional heat. Theshunt (QN11) adjusts, so the true supply temperatureagrees with the control system’s theoretical, calculated,set point value. When the heating demand drops suffi-ciently, so the additional heat is no longer required, theshunt (QN11) closes completely. Factory set minimumrun time for the boiler is 12 hours (can be set in menu5.1.12).

The settings for shunt controlled additional heat aremade in menu 4.9.3 and menu 5.1.12.

Connect the shunt motor (QN11) to terminal block-AA101-X7:4 (230 V, open) and 3 (230 V, close).

To control switching the additional heat on and off,connect it to terminal block -AA101-X7:2.

Post adjustment and venting

Pump adjustment, automatic operation

Brine side

The brine pump must run at the correct speed for thecorrect flow in the brine system. F1345 has a brine pumpthat can be automatically controlled in standard mode.Certain functions and accessories may require that theyare run manually and the correct speed must then beset, see section Pump adjustment, manual operation.

If several F1345 are installed in a master/slave configur-ation, all F1345 must be the same size (e.g. 60 kW) forthe automatic control to work. If the installation contains,e.g. one 60 kW and one 40 kW, manual operation adjust-ments must be made, see page 37.

The automatic control occurs when the compressor isrunning and it sets the speed of the brine pump to obtainthe optimal temperature difference between the supplyand return lines. For passive cooling operation, for ex-ample, the brine pump must run at a set speed, whichis set in menu 5.1.9

Heating medium side

The heating medium pump must run at the correct speedfor the correct flow in the heating medium system, F1345has a heating medium pump that can be automaticallycontrolled in standard mode. Certain functions and ac-cessories may require that they are run manually andthe correct speed must then be set, see section Pumpadjustment, manual operation.

This automatic control occurs when the compressor isrunning and sets the speed of the heating mediumpump, for the present operating mode, to obtain theoptimal temperature difference between the supply andreturn lines. During heating operation, the set DOT (di-mensioned outdoor temperature) and temperature dif-ferential in menu 5.1.14 are used. If necessary, the max-imum speed of the circulation pump can be limited inmenu 5.1.11.

Pump adjustment, manual operation

Brine side

To set the correct flow in the brine system, the correctspeed must be set for the brine pumps. F1345 has brinepumps that can automatically controlled, but if manualspeed is wanted they must be set according to the fol-lowing information. For manual operation, “auto” mustbe deactivated in menu 5.1.9.

The flow must have a temperature difference betweenbrine out (BT11) and brine in (BT10) of 2 - 5 °C when thesystem is balanced (suitably 5 minutes after compressorstart). Check these temperatures in menu 3.1 "serviceinfo" and adjust the brine pump (GP2) speed until thetemperature difference is achieved. A high differenceindicates a low brine flow and a low difference indicatesa high brine flow.

Set the speed of the brine pump in menu 5.1.9, see theOperating Manual.

Read off what speed the brine pump should have duringmanual operation from the diagram below.
