13 4 Pipe and ventilati cnectis General pipe cnectis Pipe installati must be carried out in accordance with current norms and directives. The system requires the radiator circuit to be designed for a low temperature heating medium. At the lowest dimensied outdoor temperature (DOT) the highest recommended temperatures are 55 C the supply line and 45 C the return line. Overflow water from the evaporator collecti tray and safety valves goes via overflow cup to a drain so that hot water splashes cannot cause injury. The entire length of the overflow water pipe must be inclined to prevent water pockets and must also be frost-proof. The pipe system needs to be flushed out before the heat pump is cnected so that any debris cannot damage compent parts. Cauti Ensure that incoming water is clean. When using a private well, it may be necessary to supplement with an extra water filter. System diagram F750 csists of a heat pump, water heater, buffer vessel, immersi heater, fan, circulati pump and ctrol system.f750 is cnected to the ventilati system and heating medium circuits. When the exhaust air at room temperature passes through the evaporator, the refrigerant evaporates because of its low boiling point. In this way the energy in the room air is transferred to the refrigerant. The refrigerant is then compressed in a compressor, causing the temperature to rise csiderably. The warm refrigerant is led to the cdenser. Here the refrigerant gives its energy to the heating system water, whereup the refrigerant changes state from gas to liquid. The refrigerant then goes via filters to the expansi valve, where the pressure and temperature are reduced. The refrigerant has now completed its circulati and returns to the evaporator. Extract air Exhaust air Maximum boiler and radiator volumes The volume of the pressure expansi vessel (CM1) is 10 litres and it is pre-pressurised as standard to 0.5 bar (5 mvp). As a result, the maximum permitted height "H" between the vessel and the highest radiator is 5 m, see figure. If the standard initial pressure in the pressure vessel is not high enough it can be increased by adding air via the valve in the expansi vessel. The initial pressure of the expansi vessel must be stated in the inspecti document. Any change in the initial pressure affects the ability of the expansi vessel to handle the expansi of the water. The maximum system volume excluding the boiler is 260 litres at the above pre-pressure.

17 Installati alternative F750 can be installed in several different ways, some of which are shown below. Further opti informati is available at and in the respective assembly instructis for the accessories used. See page 51 for a list of the accessories that can be used with F750. More informati about the optis is available at Separated/e unit F750 is delivered as e unit and can be installed as e unit or separated. For separate installati the accessory DKI 10 is required. The images in this manual show F750 installed as e unit. Extra hot water heaters The heat pump should be supplemented with an extra water heater, if a large bath tub or other significant csumer of hot water is installed. Water heater without immersi heater In water heaters without an immersi heater, the water is heated by the heat pump's compressor. The water heater is best positied to the left of F750. cw kv hw vv LEK One unit Separated installati Water heater with immersi heater If it is possible to use a water heater with an immersi heater, NIBE COMPACT or EMINENT type water heaters can be used. If the valve cnector is to be installed externally, moved out or separated, it must be replaced with a separable cnector Ø 22 mm. HW from F750 Chapter 4 Pipe and ventilati cnectis 17

18 Cnecting hot water circulati To reduce the risk of bacterial growth in systems with hot water circulati, the temperature of the circulating water should not fall below 50 C. There should not be any n-circulatory hot water pipes. Adjust the hot water system so that the temperature does not fall below 50 ー C at the extremities of the system. The circulati pump for hot water circulati can be ctrolled by the heat pump. The HWC return can be cnected to XL5 or a freestanding water heater. If an electric water heater is cnected after the heat pump, the HWC return must be cnected to the water heater. Two or more climate systems When more than e climate system is to be heated, the following cnecti can be used. The ECS 40/ECS 41 accessory is required for this cnecti. 18 Chapter 4 Pipe and ventilati cnectis

19 General ventilati cnecti Ventilati installati must be carried out in accordance with current norms and directives. To prevent fan noise being transferred to the ventilati devices, it may be a good idea to install a silencer in the duct system. This is especially important if there are ventilati devices in noise sensitive rooms. Cnectis must be made via flexible hoses, which should be installed so that they are easy to replace. The extract air duct must be provided with diffusi-tight insulati (PE30) over its entire length. Ensure that the cdensati insulati is sealed at any joints and/or at lead-in nipples, silencers, roof cowls or similar. Provisi must be made for inspecti and cleaning of the duct. Make sure that there are no reductis of cross-sectial area in the form of creases, tight bends etc., since this will reduce the ventilati capacity. The air duct system must be a minimum of air tightness class B. The extract air duct must be a maximum of 20 m lg with a maximum of six bends. The ventilati ducts should be installed in such a way that it is easy to open the inverter box. The extract air duct should, if possible, be routed up through the roof. If the duct is to be routed out through an external wall, avoid having a 90 degree bend backward, as this can cause noise and poorer capacity. F750 has a very low extract air temperature. To avoid damaging the product and/or the house, it is therefore important that the extract air ducts are insulated with diffusi-proof material (PE30) alg their entire length. TIP If additial cdensati insulati (PE30) dimensi Ø 200 is installed the outside of the existing exhaust line between the heat pump and the inner roof, the noise in the installati area is reduced by 1-2 db(a). Extract air Exhaust air Ventilati flow LEK Cnect F750 so that all exhaust air except kitchen duct air (kitchen fan) passes the evaporator (EP1) in the heat pump. The lowest ventilati flow must comply with the applicable natial standards. For optimum heat pump performance, the ventilati flow should not be less than 31 l/s (110 m³/h). Ensure that the ventilati openings are not blocked. Set the ventilati capacity in the heat pump's menu system (menu 5.1.5). If the exhaust air temperature falls below 16 C, the compressor is blocked and electric additial heat is permitted. Heat is not recovered from the exhaust air when the compressor is blocked. 350 Adjusting ventilati To obtain the necessary air exchange in every room of the house, the exhaust air devices must be correctly positied and adjusted and the fan in the heat pump adjusted. Immediately after installati adjust the ventilati so that it is set according to the projected value of the house. Incorrect ventilati adjustment may lead to reduced installati efficiency and thus poorer operating ecomy, and may result in moisture damage to the house Exhaust air duct /kitchen fan Exhaust air duct (kitchen fan) must not be cnected to F750. To prevent food vapour being transferred to F750 the distance between the kitchen fan and the exhaust air device must be csidered. The distance should not be less than 1.5 m, but this can vary between different installatis. Always use a kitchen fan when cooking. A duct in a masry chimney stack must not be used for extract air.

20 5 Electrical cnectis General All electrical equipment, except the outdoor sensors, room sensors and the current sensors are ready cnected at the factory. Discnect the heat pump before insulati testing the house wiring. Electrical installati and service must be carried out under the supervisi of a qualified electrician. Cut the current with the circuit breaker before carrying out any servicing. Electrical installati and wiring must be carried out in accordance with the stipulatis in force. F750 is not switchable between 3x230V and 3x400V. If the building is equipped with an earth-fault breaker, F750 should be equipped with a separate e. FD1 FD1-S2 If a miniature circuit breaker is used, this should have at least motor characteristic C. See page 55 for fuse size. For the heat pump wiring diagram, see page 61. F750 Communicati and sensor cables to external cnectis must not be laid close to high current cables. The minimum area of communicati and sensor cables to external cnectis must be 0.5 mm² up to 50 m, for example EKKX or LiYY or equivalent. When cable routing in F750, cable grommets UB1and UB2, (marked in image) must be used. In UB1 and UB2 the cables are inserted through the heat pump from the back to the frt. For dimensis diagram see page 22. FA1 LEK Miniature circuit breaker (FA1) Operati (230V), fan, circulati pumps etc. are internally fused by a miniature circuit breaker (FA1). Cauti UB1 F750 UB2 Check the miniature circuit-breaker (FA1). It may have tripped during transportati. Temperature limiter (FD1) The temperature limiter (FD1) cuts the current supply to the electric additial heat if the temperature rises between 90 and 100 C and can be manually reset. LEK Switch (SF1) must not be moved to " " or " " until F750 has been filled with water. Otherwise the temperature limiter, thermostat and the immersi heater may be damaged. Resetting The temperature limiter (FD1) is accessible behind the frt cover. Reset the temperature limiter by carefully pressing the butt (FD1-SF2) using a small screwdriver. LEK / APH Check the cnectis, main voltage and phase voltage before the machine is started, to prevent damage to the heat pump electrics. If the supply cable is damaged, ly NIBE, its service representative or similar authorised pers may replace it to prevent any danger and damage. 20 Chapter 5 Electrical cnectis

22 Cnectis To prevent interference, unscreened communicati and/or sensor cables to external cnectis must not be laid closer than 20 cm from high voltage cables. Power cnecti F750 must be installed via an isolator switch with a minimum breaking gap of 3mm. Minimum cable area must be sized according to the fuse rating used. Supplied cable (length approx. 2 m) for incoming supply electricity is cnected to terminal block X1 the immersi heater board (AA1). The cnecti cable can be found the back of F750 (see dimensis diagram below) F750 is not switchable between 3x230V and 3x400V. Cnecti 3x400V Tariff ctrol If the voltage to the immersi heater and/or the compressor disappears for a certain period, there must also be blocking via the AUX-input at the same time, see "Possible selecti for AUX inputs". Cnecting external operating voltage for the ctrol system Only applies to power cnecti of 3x400V. Mark up any juncti boxes with warnings for external voltage. If you wish to cnect external operating voltage for the ctrol system to F750 the immersi heater circuit board (AA1) the edge cnector at AA1:X2 must be moved toaa1:x9 (as illustrated). When cnecting external operating voltage for the ctrol system with separate earth-fault breaker, discnect the blue cable from terminal block X7:24 the immersi heater circuit board (AA1) and cnect in the enclosed top clamp together with the incoming operating zero. Cnect a blue cable (min 0.75 mm 2 ) between the top clamp and X11:N the immersi heater circuit board (as illustrated). Operating voltage (230VAC) is cnected to AA1:X11 (as illustrated).

23 F750 LEK F750 LEK Outside sensor Install the outdoor temperature sensor (BT1) in the shade a wall facing north or north-west, so it is unaffected by the morning sun for example. Cnect the sensor to terminal block X6:1 and X6:2 the input board (AA3). Use a twin core cable of at least 0.5 mm² cable area. If a cduit is used it must be sealed to prevent cdensati in the sensor capsule. AA3-X6 External BT1 F AA3-X6 Room sensor F750 is supplied with a room sensor enclosed (BT50). The room sensor has up to three functis: 1. Show current room temperature in F750's display. 2. Opti of changing the room temperature in C. 3. Makes it possible to change/stabilise the room temperature. Install the sensor in a neutral positi where the set temperature is required. A suitable locati is a free inner wall in a hall approx. 1.5 m above the floor. It is important that the sensor is not obstructed from measuring the correct room temperature by being located, for example, in a recess, between shelves, behind a curtain, above or close to a heat source, in a draft from an external door or in direct sunlight. Closed radiator thermostats can also cause problems. The heat pump operates without the sensor, but if e wishes to read the accommodati's indoor temperature in F750's display, the sensor must be installed. Cnect the room sensor to X6:3 and X6:4 the input board (AA3). If the sensor is to be used to change the room temperature in C and/or to change/stabilise the room temperature, the sensor must be activated in menu If the room sensor is used in a room with underfloor heating, it should ly have an indicatory functi, not ctrol of the room temperature. External RG 05 F750 F AA3-X6 BT50 AA3-X6 Cauti Changes of temperature in accommodati take time. For example, short time periods in combinati with underfloor heating will not give a noticeable difference in room temperature. Chapter 5 Electrical cnectis 23

The heat pump has integrated load mitors that ctrol the electrical steps for the electrical additi by redistributing the power between the different phases or disengaging in event of overload in a phase. Recnecti occurs when other current csumpti is reduced. NIBE Uplink Cnect the network cnected cable (straight, Cat.5e UTP) with RJ45-ctact (male) to RJ45 ctact (female) the rear of the heat pump. Cnecting current sensors The building's phases can have different loads. If the inverter is cnected to a heavily loaded phase, there is a risk of the compressor shutting down and the electrical additi operating lger than expected. This means that savings will not be as expected. A current sensor should be installed each incoming phase cductor in to the distributi box to measure the current. The distributi box is an appropriate installati point. Cnect the current sensors to a multi-core cable in an enclosure next to the electrical distributi unit. The multi-core cable between the enclosure and the heat pump must have a cable area of at least 0.5 mm². Cnect the cable to the input board (AA3) terminal X4:1-4 block - where X4:1 is the comm terminal block for the three current sensors. The size of the property's main fuse is set in menu Incoming Inkommande electricity PEN L1 L 2 L 3 External cnecti optis F750 has software ctrolled inputs and outputs the input card (AA3), for cnecting the external switch functi or sensor. This means that when an external switch functi or sensor is cnected to e of six special cnectis, the correct functi must be selected to the correct cnecti in the software in F750. Cauti If an external switch functi or sensor is cnected to F750, the functi to use input or output must be selected in menu 5.4, see page 44. Selectable inputs the input card for these functis are AUX1 (X6:9-10), AUX2 (X6:11-12), AUX3 (X6:13-14), AUX4 (X6:15-16) and AUX5 (X6:17-18).

27 Cauti Some of the following functis can also be activated and scheduled via menu settings. Possible selecti for AUX inputs Switch for external blocking of additi and/or compressor Blocking for additi heat and compressor is cnected two different AUX inputs. If external blocking of additial heat and/or compressor is wanted, this can be cnected to terminal block X6 the input board (AA3), which is positied behind the frt cover. The additial heat and/or the compressor are discnected by cnecting a potential-free switch functi to the input selected in menu 5.4, see page 44. External blocking of additi and compressor can be combined. A closed ctact results in the electrical output being discnected. Blocking via AUX input is required during tariff ctrol Ctact for external tariff blocking In those cases where external tariff blocking is used, it can be cnected to terminal block X6 the input board (AA3), which is positied behind the frt cover. Tariff blocking means that the additial heat, the compressor, the heating and hot water are blocked by cnecting a potential-free switch functi to the input selected in menu 5.4, see page 44. Closed switch means that tariff blocking is activated. When tariff blocking is activated, the min. supply line does not apply. Switch for "SG ready" This functi can ly be used in mains networks that support the "SG Ready"-standard. "SG Ready" requires two AUX inputs. In cases where this functi is required, it must be cnected to terminal block X6 the input card (AA3). "SG Ready" is a smart form of tariff ctrol where your electricity supplier can affect the indoor and hot water temperatures or simply block the additial heat and/or the compressor in the heat pump at certain times of the day (can be selected in menu after the functi is activated). Activate the functi by cnecting potentialfree switch functis to two inputs selected in menu 5.4 (SG Ready A and SG Ready B), see page 44. Closed or open switch means e of the following: Blocking (A: Closed, B: Open) "SG Ready" is active. The compressor in the heat pump and additial heat is blocked like the day's tariff blocking. Normal mode (A: Open, B: Open) "SG Ready" is not active. No effect the system. Low price mode (A: Open, B: Closed) "SG Ready" is active. The system focuses costs savings and can for example exploit a low tariff from the electricity supplier or over-capacity from any own power source (effect the system can be adjusted in the menu 4.1.5). Overcapacity mode (A: Closed, B: Closed) "SG Ready" is active. The system is permitted to run at full capacity at over capacity (very low price) with the electricity supplier (effect the system is settable in menu 4.1.5). (A = SG Ready A and B = SG Ready B ) Switch for +Adjust Using +Adjust, the installati communicates with the underfloor heating's ctrol centre* and adjusts the heat curve and calculated supply temperature according to the underfloor heating system's recnecti. Activate the climate system you want +Adjust to affect by highlighting the functi and pressing the OK butt. *Support for +Adjust required +Adjust must first be selected in menu 5.4 soft inputs/outputs. Circuit board AA3 in the installati must have at least "Input versi 34 and the software versi must have "display versi 5539 or later for +Adjust to work. The versi can be checked in menu 3.1 under input versi respectively display versi. New software can be downloaded for free from In systems with both under floor heating and radiators, NIBE ECS 40/41 should be used for optimum operati. Chapter 5 Electrical cnectis 27

28 Switch for external blocking of heating In those cases where external blocking of heat is used, it can be cnected to terminal block X6 the input board (AA3), which is positied behind the frt cover. Heating operati is discnected by cnecting a potential-free switch functi to the input selected in menu 5.4, see page 44. A closed switch results in blocked heating operati. When heat blocking is activated, the min. supply line does not apply. Switch for external blocking of hot water In cases where external blocking of hot water is used, this can be cnected to terminal block X6 the input board (AA3), which is positied behind the frt cover. Hot water operati is discnected by cnecting a potential-free switch functi to the input selected in menu 5.4, see page 44. A closed switch results in blocked hot water operati. Ctact for activati of temporary lux" An external switch functi can be cnected to F750 for activati of the hot water functi "temporary lux". The switch must be potential-free and cnected to the selected input (menu 5.4, see page 44) terminal block X6 the input board (AA3). "temporary lux" is activated for the time that the ctact is cnected. Ctact for activati of external adjustment" An external ctact functi can be cnected to F750 to change the supply temperature and the room temperature. When the switch is closed the temperature changes in C (if the room sensor is cnected and activated). If a room sensor is not cnected or activated, the desired change of "temperature" (heating curve set) with the number of steps selected is set. The value is adjustable between -10 and +10. climate system 1 The switch must be potential-free and cnected to the selected input (menu 5.4, see page 44) terminal block X6 the input board (AA3). The value for the change is set in menu 1.9.2, "external adjustment". climate system 2 to 8 External adjustment for climate systems 2 to 8 requires accessories (ECS 40 or ECS 41). See the accessory s installer handbook for installati instructis. Ctact for activati of fan speed An external ctact functi can be cnected to F750 for activati of e of the four fan speeds. The switch must be potential free and cnected to the selected input (menu 5.4, see page 44) terminal blockx6 the input circuit board (AA3). When the switch closes, the selected fan speed is activated. Normal speed is resumed when the ctact is opened again. Level mitor for the drip tray The level sensor for the overflow cup is cnected to the selected input (menu 5.4, see page 44) terminal block X6 the input card (AA3). The input must be closed during normal operati. Possible selecti for AUX output (potential free variable relay) It is possible to have an external cnecti through the relay functi via a potential-free variable relay (max 2 A) the input circuit board (AA3), terminal block X7. Optial functis for external cnecti: Indicati of buzzer alarm. Ctrol of circulati pump for hot water circulati. External circulati pump, for example external pump and shunt group.

Cauti Check the miniature circuit-breaker (FA1) in the heat pump. It may have tripped during transportati. Venting the climate system 1. Set the switch (SF1) in mode and wait approx. 30 secds. 2. Turn the power supply to the heat pump. 3. Vent the heat pump via the vent valves (QM20), (QM22), (QM23), (QM24) and the rest of the climate system via the relevant vent valves. 4. Keep topping up and venting until all air has been removed and the pressure is correct. Filling and venting The vent hoses from the ctainer must be drained of water before air can be released. This means that the system is not necessarily vented despite the flow of water when the vent valves (QM20), (QM22), (QM23), (QM24) are opened. Filling the hot water heater 1. Open a hot water tap in the house. 2. Open the filling valve (QM10). This valve should then be fully open during operatis. 3. When water comes out of the hot water tap, the hot water heater is full and the tap can be closed. F750, copper QM10 QM11 FL2 QM31 QM24 FL1 Filling the climate system 1. Check that the shut valve for the heating system (QM31) is open. 2. Open the vent valves (QM20), (QM22), (QM23) and (QM24). 3. For F750, stainless steel: Check if the flexi hose supplied is cnected between cnecti (QM11) and cnecti (QM13). Adjust the hose if this has not been de. 4. For F750, copper: Open the filling valve (QM11). The boiler secti and the rest of the climate system are filled with water For F750, stainless steel: Open the filler valves (QM11) and (QM13).

Maintenance Inform the user of necessary maintenance acti. Cleaning the overflow cup/floor drain Regularly check that the overflow cup and any floor drains are not blocked; water must be able to run through freely. Clean, if necessary. If the overflow cup or floor drain is blocked, water can run over to the floor of the installati area. To prevent damage to the building the floor coating must be csidered. A waterproof floor or floor membrane is recommended. Service actis Emergency mode Emergency mode is used in event of operatial interference and in cjuncti with service. Emergency mode is activated by setting switch (SF1) in mode " ". This means that: The status lamp illuminates yellow. The display is not lit and the ctrol computer is not cnected. The temperature at the immersi heater is ctrolled by the thermostat (FD1-BT30). It can be set either to 35 or 45 C. The compressor is switched and ly the fan, heating medium pump 2 and the electric additial heat are active. The additial heat power in emergency mode is set in the immersi heater board (AA1). See page 25 for instructis. Draining the water heater The water heater can be drained via the safety valve (FL1) or via the overflow cup (WM1). 1. Discnect the overflow pipe from the safety valve (FL1) and cnect a hose to a draining pump instead. If a draining pump is not available, the water can be released into the overflow cup (WM1). 2. Open the safety valve (FL1). 3. Open a hot water tap to let air into the system. If this is not sufficient, detach the pipe cnecti (XL4) the hot water side and ensure that air is entering. There may be some hot water when draining the heating medium side/climate system. There is a risk of scalding. The hot water can be tapped through safety valve (FL2) via the overflow cup (WM1) or through a hose that is cnected to the safety valve's (FL2) or the drain valve's (XL10) outlet. 1. Open the safety valve (FL2) or the drain valve (XL10). 2. Set the vent valves for the climate system (QM20), (QM22), (QM23), (QM24) in the open positi for air supply. The heat pump should not, after draining, be exposed to risk of freezing because a certain of water remains in the coil. Helping the circulati pump to start (GP1) 1. Shut, F750 by setting the switch ((SF1)) to " ". 2. Remove the frt cover 3. Loosen the venting screw (QM5) with a screwdriver.

49 10 Disturbances in comfort In most cases, the heat pump notes operatial interference (operatial interference can lead to disturbance in comfort) and indicates this with alarms and shows acti instructis in the display. Info-menu All the heat pump measurement values are gathered under menu 3.1 in the heat pump menu system. Looking through the values in this menu can often simplify finding the source of the fault. See help menu or user manual for more informati about menu 3.1. Manage alarm alarm info / acti reset alarm aid mode Low pressure alarm In the event of an alarm, some kind of malfuncti has occurred, which is indicated by the status lamp changing from green ctinuously to red ctinuously. In additi, an alarm bell appears in the informati window. Alarm In the event of an alarm with a red status lamp a malfuncti has occurred that the heat pump cannot remedy itself. In the display, by turning the ctrol knob and pressing the OK butt, you can see the type of alarm it is and reset it. You can also choose to set the heat pump to aid mode. info / acti Here you can read what the alarm means and receive tips what you can do to correct the problem that caused the alarm. reset alarm In most cases it is enough to select reset alarm to correct the problem that caused the alarm. If a green light illuminates after selecting "reset alarm" the alarm has been remedied. If a red light is still visible and a menu called alarm is visible in the display, the problem that caused the alarm remains. If the alarm disappears and then returns, see the secti "Troubleshooting". aid mode aid mode is a type of emergency mode. This means that the heat pump produces heat and/or hot water despite there being some kind of problem. This can mean that the heat pump's compressor is not running. In this case the immersi heater produces heat and/or hot water. To select aid mode an alarm acti must be selected in the menu Cauti Selecting "aid mode is not the same as correcting the problem that caused the alarm. The status lamp will therefore ctinue to be red.
