Delivery and handling

Transport
F2050 should be transported and stored vertically in a dry place.
NOTE
Ensure that the heat pump cannot fall over during transport.
Check that F2050 has not been damaged during transport.
LIFT FROM THE STREET TO THE SET UP LOCATION
If the surface allows, the easiest method is to use a pallet truck to move the heat pump to the installation area.
If the heat pump needs to be transported across soft ground, such as a lawn, we recommend using a crane truck that can lift it to the installation location. When the heat pump is lifted with a crane, the packaging must be intact. If a crane truck cannot be used, the heat pump can be transported on an extended sack truck. The heat pump must be taken hold of from its heaviest side and two people are required to lift it.
LIFT FROM THE PALLET TO FINAL POSITIONING
Before lifting remove the packaging and the securing strap to the pallet. Place lifting straps around each foot. It is recommended that two people perform the lift from the pallet to the base.
SCRAPPING
When scrapping, remove the heat pump in reverse order. In this case, lift by the base plate rather than the pallet!
Assembly
· Place the heat pump in a suitable location outdoors to prevent any risk of the refrigerant flowing in through ventilation openings, doors or similar openings in the event of a leak. It must also not constitute a hazard to people or property in any other way.
· If the heat pump is placed in a location where any refrigerant leak could accumulate, for example below ground level (in a dip or low-lying recess), the installation must satisfy

the same requirements that apply for gas detection and the ventilation of engineering rooms. Requirements regarding sources of ignition must be applied where appropriate.
· Place F2050 outdoors on a solid level base that can take the weight, preferably a concrete foundation. If concrete slabs are used they must rest on asphalt or shingle.
· The lower edge of the evaporator must not be lower than the level of the average local snow depth, or at least 300 mm above ground level. The base should be at least 70 mm tall.
· F2050 should not be positioned next to noise sensitive walls, for example, next to a bedroom.
· Also ensure that the placement does not inconvenience the neighbours.
· F2050 must not be placed so that recirculation of the outdoor air is possible. Recirculation entails reduced power and impaired efficiency.
· The evaporator must be sheltered from direct wind / , which negatively affects the defrosting function. Place F2050 protected from wind / against the evaporator.
· Large amounts of condensation, as well as melt water from defrosting, may be produced. Condensation must be led off to a drain or similar (see section “Condensation water”).
· Care must be exercised so that the heat pump is not scratched during installation.

  • The space behind must not exceed 500 mm in locations that are exposed to the wind.

Condensation
The condensate drain pan collects and leads away the condensation water.
NOTE
It is important to the heat pump function that condensation water is led away and that the drain for the condensation water run off is not positioned so that it can cause damage to the house.
Condensation run-off should be checked regularly, especially during the autumn. Clean if necessary.
· The condensation water (up to 50 litres / 24 hrs) must be routed away by a pipe to an appropriate drain, it is recommended that the shortest outdoor length possible is used.
· The section of the pipe that can be affected by frost must be heated by the heating cable to prevent freezing.

DRAIN PAN HEATER, CONTROL
The drain pan heater is supplied with power when one of the following conditions is met: 1. The compressor has been in operation for at least 30
minutes after last start. 2. The ambient temperature is lower than 1 °C.
DRAINAGE OF CONDENSATION
Caution
If none of the following recommended alternatives is used, good drainage of condensation must be provided.
Stone caisson

TIP
Pipe with heating cable for draining the condensation water trough is not included.

TIP
To ensure this function, the accessory KVR should be used.

Frost proof Frostfridttedpjtuhp

· Route the pipe downward from the heat pump.
· The outlet of the condensation water pipe must be at frost free depth.
· Use a water trap for installations where air circulation may occur in the condensation water pipe.
· The insulation must seal against the bottom of the condensation water trough.

LEK
If the house has a cellar the stone caisson must be positioned so that condensation water does not affect the house. Otherwise the stone caisson can be positioned directly under the heat pump.

F2050 can only operate up to a return temperature of about 55 °C and an outgoing temperature of about 58 °C from the heat pump.

F2050 is not equipped with shut-off valves on the heating medium side, rather these must be installed to facilitate any future servicing. The return temperature is limited by the return line sensor.

WATER VOLUMES
When docking with F2050 free flow in the climate system is recommended for correct heat transfer. This can be achieved by use of a bypass valve. If free flow cannot be ensured, it is recommended that a buffer tank (NIBE UKV) is installed.

Following water volumes are recommended

Caution
There is a difference between connection to a control module compared with connection to an indoor module. See the Installer Manual for the indoor module/control module.
Vent the heat pump by the “heating medium supply” connection (XL1) using the venting nipple on the enclosed flexible hose. Install as follows: · expansion vessel · pressure gauge · safety valves · drain valve
For draining the heat pump during prolonged power failures. · non-return valve Installations with only one heat pump: a non-return valve is only required in those cases where the placement of the products in relation to each other can cause self-circulation. Cascade installations: each heat pump must be fitted with a non-return valve. · charge pump · shut-off valve To facilitate any future servicing. · enclosed filterball (QZ2) Installed before connection “heating medium return” (XL2) (the lower connection) on the vacuum pump. · reversing valve.

Compressor heater
F2050 (does not apply to F2050-6) is equipped with a compressor heater that heats the compressor before startup and when the compressor is cold.
NOTE
The compressor heater must have been connected for 6 ­ 8 hours before the first start, see the section “Start-up and inspection” in the Installer Manual for the indoor section
30 Chapter 6 | Commissioning and adjusting

NIBE F2050

Start-up and inspection
1. The compressor heater (CH) must have been operational for at least 6 – 8 hours before the compressor start can be initiated. This is done by switching on the control voltage and disconnecting the communication cable.
2. F2050 must be addressed, if it is to have an address other than 1. See chapter “Addressing via cascade connection”.
3. The communication cable on the terminal block AA23X4 must not be connected.
4. Turn the isolator switch on.
5. Ensure that the F2050 is connected to the power source.
6. After 6 ­ 8 hours, connect the communication cable (W2) to the terminal block AA23-X4.
7. Restart the indoor module. Follow the instructions for “Start-up and inspection” in the installation manual for the indoor module.
The heat pump starts 30 minutes after the outdoor unit has been powered up and the communication cable (W2) has been connected, if necessary.
If scheduled silent operationis required, it must be scheduled in the inner section or control unit.
NOTE
Do not start any electrical work until at least two minutes after cutting the power.
Caution
Silent mode should only be scheduled periodically because the maximum output is limited to approx. the nominal values.

Readjusting, heating medium side
Air is initially released from the hot water and venting may be necessary. If bubbling sounds can be heard from the heat pump, the circulation pump and radiators the entire system will require further venting. When the system is stable (correct pressure and all air eliminated) the automatic heating control system can be set as required.
Adjustment, charge flow
Instructions for adjusting hot water charging are in the Installer Manual for the relevant indoor module. See section Accessories for a list of the indoor units and accessories that can be connected to F2050.

Disturbances in comfort

In most cases, the indoor module/control module notes a malfunction (a malfunction can lead to disturbance in comfort) and indicates this with alarms and action instructions in the display.
Troubleshooting
NOTE
In the event of action to rectify malfunctions that require work within screwed hatches, the incoming supply electricity must be isolated at the safety switch by or under the supervision of a qualified electrician.
Caution
Alarms are acknowledged on the indoor module / control module.
If the operational interference is not shown in the display the following tips can be used:
BASIC ACTIONS
Start by checking the following: · All supply cables to the heat pump are connected. · Group and main fuses of the accommodation. · The property’s earth circuit breaker. · The heat pump’s fuse / automatic protection. (FC1 / FB1,
FB1 only if KVR is installed.) · The indoor module’s/control module’s fuses. · The indoor module’s/control module’s temperature lim-
iters. · That the air flow to F2050 is not blocked by foreign ob-
jects. · That F2050 does not have any external damage.
F2050 DOES NOT START
· There is no demand. ­ The indoor module/control module does not call on heating, cooling or hot water.
· Compressor blocked due to the temperature conditions. ­ Wait until the temperature is within the product’s working range.
· Minimum time between compressor starts has not been reached. ­ Wait for at least 30 minutes and then check if the compressor has started.
· Alarm tripped. ­ Follow the display instructions.

F2050 NOT COMMUNICATING
· Check that the addressing of F2050 is correct. · Check that the communication cable is correctly connec-
ted and working.
LOW HOT WATER TEMPERATURE OR A LACK OF HOT WATER
Caution
The setting for the hot water is always performed on the indoor module or the control module.
This part of the fault-tracing chapter only applies if the heat pump is docked to the hot water heater. · Large hot water consumption.
­ Wait until the hot water has heated up. · Incorrect hot water settings in indoor module or control
module. ­ See the Installer Manual for the indoor module/control
module. · Clogged filterball.
­ Switch off the system. Check and clean the filterball.
LOW ROOM TEMPERATURE
· Closed thermostats in several rooms. ­ Set the thermostats to max in as many rooms as possible.
· Incorrect settings in indoor module or control module. ­ See the Installer Manual for the indoor module/control module.
· Air-filled radiators/underfloor heating coils. ­ Bleed the system.
HIGH ROOM TEMPERATURE
· Incorrect settings in indoor module or control module. ­ See the Installer Manual for the indoor module/control module.
LARGE AMOUNT OF WATER BELOW F2050
· The accessory KVR 10 is required. · If KVR 10 is installed, check that the water drainage can
flow freely.

Sound levels

LEK

F2050 is usually placed next to a house wall, which gives a directed sound distribution that has to be taken into consideration. Accordingly, when setting up, you should always attempt to select the side that faces the least sound-sensitive neighbouring area.
The sound pressure levels are further affected by walls, bricks, differences in ground level, etc and should therefore only be seen as guide values.
F2050 adjusts the fan speed depending on the ambient temperature and evaporation temperature.
