■The area where F110 is located must be equipped
with floor drainage.
■F110 must be positioned with the back towards a
wall. Install F110 with its back to an outside wall,
ideally in a room where noise does not matter, in
order to eliminate noise problems. If this is not pos-
sible, avoid placing it against a wall behind a bed-
room or other room where noise may be a problem.
■Wherever the unit is located, walls to sound sensitive
rooms should be fitted with sound insulation.
■Route pipes so they are not fixed to an internal wall
that backs on to a bedroom or living room.

11Chapter 3 | The Heat pump designNIBE™ F110
General pipe connections
Pipe installation must be carried out in accordance with
current norms and directives.
F110 is only designed for be installed vertically. The
water heater is equipped with compression ring
couplings for copper or plastic pipes. Internal support
bushes must be fitted when a plastic pipe or annealed
copper pipe is used. The mixer valve is set for the de-
sired hot water temperature. Turn the mixer knob anti-
clockwise to increase hot water temperature. Setting
range 40–65 °C.
Overflow water from the evaporator collection tray
and safety valves goes via non-pressurised collecting
pipes 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 safety valve (FL1) must be checked regularly, about
four times a year.
1. Turn the safety valve anticlockwise.
2. Check that water flows through the safety valve
overflow pipe.
3. If no water comes out, contact the installer to re-
place the safety valve immediately.
The safety valve sometimes releases a little water after
hot water has been used. This discharge is caused by
the expansion of cold water entering the water heater,
resulting in a pressure increase, whereby the safety
valve opens.
NOTE
The pipe systems need to be flushed out be-
fore F110 is connected so that any debris can-
not damage component parts.

System diagram
F110 consists of heat pump module, water heater, im-
mersion heater and control system.
When the air passes through the evaporator, the refri-
gerant evaporates because of its low boiling point. In
this way the energy in the air is transferred to the refri-
gerant.
The refrigerant is then compressed in a compressor,
causing the temperature to rise considerably.
The warm refrigerant is led to the condenser. Here the
refrigerant gives off its energy to the hot water,
whereupon the refrigerant changes state from gas to
liquid.
The refrigerant then goes via filters to the expansion
valve, where the pressure and temperature are reduced.
The refrigerant has now completed its circulation and
returns to the evaporator.

Installation alternative
F110 must be connected according to the instructions
in this manual.
Installation must be carried out in accordance with
current standards and directives.
Exhaust air
Connecting the exhaust air
With an exhaust air connection the heat in the build-
ing's ventilation air is used to heat the hot water while
the house is ventilated.
The hot air is transferred from the rooms to the heat
pump via the house ventilation system.
NOTE
An air filter (HQ12) (enclosed), minimum clas-
sification G2, is required on the exhaust air
duct of this connection. The filter must be
cleaned regularly.
Caution
Noise from the fan can be transferred via the
ventilation ducts.
Outdoor air
Connecting the outdoor air
With outdoor air connection the heat in the outdoor
air is used to heat up the hot water.
■It is important that the pipe for the incoming air is
positioned so that exhaust air is not sucked into the
heat pump, for example by bending one of the pipes.
A combination device with grille can be used.
■The pressure drop across the system must not exceed
60 Pa. The pressure drop is affected by things like the
air pipe dimension, the number of bends and the
lengths of the pipes. Example: In a system with 160
mm air ducts and 7 bends the pipes must be a max-
imum of 8 m long.
■If incoming air to F110 contains a lot of particles and
there is a high hot water demand the heat pump
must be equipped with a filter (supplied), minimum
class G2.
■Incoming and outgoing air for the heat pump can
be cold and the ventilation pipes must therefore be
insulated along their entire length.
■The heat pump operates at outdoor temperatures
down to -10 °C.
■Attempt to find a location for F110 on the side of the
house that faces the least sound sensitive neighbour-
ing area.
Caution
Noise from the fan can be transferred via the
air ducts.
NIBE™ F110Chapter 4 | Pipe and air connections14
Surrounding air
Connecting surrounding air
With surrounding air connection the heat in the room air
is used to heat up the hot water. The outgoing air can be
used to cool a room.
■If the incoming air is taken from the same room where
the outgoing air is released it is important that the pipe
for incoming air is not located so that the outgoing air
is sucked into the heat pump. This can be prevented by
the putting a bend in one of the air pipes.
■Have sufficient ceiling height so that recirculation of the
air is avoided.
■If incoming air to F110 contains a lot of particles and
there is a high hot water demand the heat pump must
be equipped with an air filter (HQ12) (supplied), minim-
um class G2.
■Noise from the fan can be transferred to the room via
the air pipes.
■In installations where air is taken from one room and
released into another, there can be over pressure if the
room is not ventilated correctly. This can lead to damp
in the building.
Caution
Outgoing air from F110 is cold and can therefore
cool the room when it is released.
Take incoming air from one room and release the
outgoing air to the same room.
Take incoming air from one room and release the outgoing air to another room or outdoors.
15Chapter 4 | Pipe and air connectionsNIBE™ F110
General air connections
Air installation must be carried out in accordance with
applicable directives.
To prevent fan noise being transferred to the ventila-
tion devices, it may be a good idea to install a silencer
in the duct, alternatively mount the enclosed silencer
in F110.
Connections must be made via flexible hoses, which
must be installed so that they are easy to replace. Ducts
that may become cold must be insulated with diffusion-
proof material (PE30) along their entire lengths. Ensure
that the condensation insulation is sealed at any joints
and/or at lead-in nipples, silencers, roof cowls or similar.
Provision must be made for inspection and cleaning of
the duct. Make sure that there are no reductions in the
cross-sectional area in the form of kinks, tight bends
etc., since this will reduce the capacity. The air duct
system must be a minimum of air tightness class B.
If there is a high hot water demand and incoming air
to F110 contains a lot of particles the heat pump
module must be equipped with an air filter (HQ12)
(enclosed).

Install the filter cartridge
The filter cartridge has two sizes of connector, 125 mm
or 160 mm.
1. Check the diameter of the air channel for inlet air.
2. When the air duct has a large diameter (Ø 160 mm)
the inner ring must be cut out of the upper section
of the filter cartridge.
3. Cut just inside the inner edge of the outer ring us-
ing a sharp knife. The plastic is prepared for easy
cutting.
4. Press the filter cartridge into place in the connec-
tion for incoming air (XL43).

Install the connector
If the filter cartridge is not installed, the enclosed con-
nector is installed in the connection for incoming air
(XL43).
Install the silencer
1. Remove the plugs from the silencer enclosed.
2. Install the silencer in the connector for outgoing
air (XL44).
NIBE™ F110Chapter 4 | Pipe and air connections16
Exhaust air duct /kitchen fan
Exhaust air duct (kitchen fan) must not be connected
to F110.
To prevent food vapour being transferred to F110 the
distance between the kitchen fan and the exhaust air
device must be considered. The distance should not be
less than 1.5 m, but this can vary between different
installations.
Always use a kitchen fan when cooking.
NOTE
A duct in a masonry chimney stack must not
be used for extract air.
Ventilation flow (exhaust air)
Connect F110 so that all exhaust air except exhaust air
duct air (kitchen fan) passes the evaporator (EP1) in
the heat pump. For optimum heat pump performance,
the ventilation flow should not be less than 25 l/s (90
m³/h). When the exhaust air temperature is lower than
20 °C (for example at start-up and when there is no
one at home) the minimum value is 31 l/s (110 m3/h).
Ensure that the ventilation openings are not blocked.
Set the ventilation capacity in the heat pump's menu
system (menu 5.1.5).
NOTE
If the exhaust air temperature falls below 10
°C, the compressor is blocked and electric ad-
ditional heat is permitted. Heat is not re-
covered from the exhaust air when the com-
pressor is blocked.
Adjusting ventilation (exhaust
air)
To obtain the necessary air exchange in every room of
the house, the exhaust air devices must be correctly
positioned and adjusted and the fan in the heat pump
adjusted.
Immediately after installation adjust the ventilation so
that it is set according to the projected value of the
house.
A defective ventilation installation may lead to reduced
installation efficiency and thus poorer operating eco-
nomy, and may result in moisture damage to the house.
