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.

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.

CHARGE PUMP
The charge pump (not included in the product) is powered and controlled from
the indoor module/control module. It has a built-in frost protection function
and, for this reason, must not be switched off when there is a risk of
freezing.
At temperatures below +2 °C the charge pump runs periodically, to prevent the water from freezing in the charge circuit. The function also protects against excess temperatures in the charge circuit.

Commissioning and adjusting
Preparations
· Before commissioning, check that the charge circuit and climate system are
filled and well vented.
· Check the pipe system for leaks.
Filling and venting
Filling and venting the heating medium system. 1. The heating medium system is
filled with water to the
required pressure. 2. Vent the system using the venting nipple (QM20) on the
enclosed flexible hose and possibly the circulation pump.
QM20
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.

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.
