EXTRACTING THE COOLING MODULE
To simplify transport and service, the heat pump can be
separated by pulling the cooling module out from the
cabinet.
See page 61 for instructions about the separation.
Assembly
• Place F1145 on a solid foundation indoors that can
take the heat pump's weight. Use the product's ad-
justable feet to obtain a horizontal and stable set-up.
30 - 50 mm
30 - 50 mm
15 - 40 mm
20-55 mm
• Because water comes from F1145, the area where
the heating pump is located must be equipped with
floor drainage.
•Install 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 possible, avoid placing
it against a wall behind a bedroom 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.
INSTALLATION AREA
Leave a free space of 800 mm in front of the product.
Approx. 50 mm free space is required on each side, to
remove the side panels (see image). The panels do not
need to be removed during service. All service on F1145
can be carried out from the front. Leave space between
the heat pump and the wall behind (and any routing of
supply cables and pipes) to reduce the risk of any vibra-
tion being propagated.

General
Pipe installation must be carried out in accordance with
current norms and directives. F1145 can operate with
a return temperature of up to 58 °C and an outgoing
temperature from the heat pump of 70 (65 °C with only
the compressor).
F1145 is not equipped with external shut off valves;
these must be installed to facilitate any future servicing.
Caution
Ensure that incoming water is clean. When
using a private well, it may be necessary to
supplement with an extra water filter.
Caution
Any high points in the climate system, must
be equipped with air vents.
NOTE
The pipe systems need to be flushed out be-
fore the heat pump is connected so debris
cannot damage component parts.
NOTE
Water may drip from the safety valve’s over-
flow pipe. The entire length of the overflow
water pipe must be routed to a suitable drain
and be inclined to prevent water pockets, and
must also be frost-proof. The overflow pipe
must be at least the same size as the safety
valve. The overflow pipe must be visible and
its mouth must be open and not located close
to electrical components.

SYSTEM DIAGRAM
F1145 consists of heat pump, immersion heater, circu-
lation pumps and control system. F1145 is connected
to the brine and heating medium circuits.
In the heat pump evaporator, the brine (water mixed
with anti-freeze, glycol or ethanol) releases its energy
to the refrigerant, which is vaporised in order to be
compressed in the compressor. The refrigerant, of which
the temperature has now been raised, is passed to the
condenser where it gives off its energy to the heating
medium circuit and, if necessary, to any docked water
heater. If there is a greater need for heating/hot water
than the compressor can provide there is an integrated
immersion heater.

Brine side
COLLECTOR
Caution
The length of the collector hose varies depend-
ing on the rock/soil conditions, climate zone
and on the climate system (radiators or under-
floor heating) and the heating requirement of
the building Each installation must be sized in-
dividually.
Max. length per coil for the collector should not exceed
400 m.
In those cases where it is necessary to have several
collectors, these should be connected in parallel with
the possibility for adjusting the flow of the relevant coil.
For surface soil heat, the hose should be buried at a
depth determined by local conditions and the distance
between the hoses should be at least 1 metre.
For several bore holes, the distance between the holes
must be determined according to local conditions.
Ensure the collector hose rises constantly towards the
heat pump to avoid air pockets. If this is not possible,
airvents should be used.
Because the temperature of the brine system can fall
below 0 °C, it must be protected against freezing down
to -15 °C. When making the volume calculation, use 1
litres of ready mixed brine per metre of collector hose
(applies when using PEM-hose 40x2.4 PN 6.3) as a guide
value.
SIDE CONNECTION
It is possible to angle the brine connections, for connec-
tion to the side instead of top connection.
To angle out a connection:
1. Disconnect the pipe at the top connection.
2. Angle the pipe in the desired direction.
3. If necessary, cut the pipe to the desired length.
CONNECTING THE BRINE SIDE
• Insulate all indoor brine pipes against condensation.
•The level vessel must be installed as the highest point
in the brine system on the incoming pipe before the
brine pump (Alt. 1).
If the level vessel cannot be placed at the highest
point, an expansion vessel must be used (Alt. 2).
NOTE
Note that condensation may drip from the level
vessel. Position the vessel so that this does
not harm other equipment.
• Details of the antifreeze used must be shown on the
level vessel.
•Install the enclosed safety valve below the level vessel
as illustrated.
• Install shut off valves as close to the heat pump as
possible.
• Fit the enclosed particle filter on the incoming brine.
TIP
If filling connection KB25/KB32 is used, the
enclosed filterball does not need to be fitted.
In the case of connection to an open groundwater sys-
tem, an intermediate frost-protected circuit must be
provided, because of the risk of dirt and freezing in the
evaporator. This requires an extra heat exchanger.

CONNECTING THE CLIMATE SYSTEM
A climate system is a system that regulates indoor
comfort with the help of the control system in F1145
and for example radiators, underfloor heating/cooling,
fan convectors etc.
• Install all required safety devices, shut-off valves (as
close to the heat pump as possible), and supplied
particle filter.
17Chapter 4 | Pipe connectionsNIBE F1145

• Fit safety valve on heating medium return as illus-
trated. Recommended opening pressure is 0.25 MPa
(2.5 bar). For information about max opening pressure,
see technical specifications.
• When connecting to a system with thermostats on all
radiators (or underfloor heating coils), either a bypass
valve must be fitted or some of the thermostats must
be removed to ensure there is sufficient flow.
P
XL1
XL2
Cold and hot water
CONNECTING THE HOT WATER HEATER
• Fit shut-off valve, non-return valve and safety valve as
illustrated.
•The safety valve must have a maximum 1.0 MPa (10.0
bar) opening pressure and be installed on the incoming
domestic water line as shown.
• A mixer valve must also be installed, if the factory
setting for hot water is changed. National regulations
must be observed.
• Hot water production is activated in the start guide or
in menu 5.2.

FIXED CONDENSING
If F1145 is to work towards a water heater with fixed
condensing, you must connect external supply temper-
ature sensor (BT25) according to the description on page
24. In addition, you must make the following menu
settings.

Docking alternatives
F1145 can be connected in several different ways, some
of which are shown below.
Further option information is available at nibe.eu and in
the respective assembly instructions for the accessories
used. See page 68 for a list of the accessories that can
be used with F1145.
BUFFER VESSEL
If the climate system volume is too small for the heat
pump output, the radiator system can be supplemented
with a buffer vessel, for example NIBE UKV.
GROUND WATER SYSTEM
An intermediate heat exchanger is used to protect the
heat pump's exchanger from dirt. The water is released
into a buried filtration unit or a drilled well. See page 29
for more information about connecting a ground water
pump.
If this docking alternative is used, "min. brine out" in
menu 5.1.7 "br pmp al set." must be changed to a suit-
able value to prevent freezing of the heat exchanger.

NIBE F1145Chapter 4 | Pipe connections18

VENTILATION RECOVERY
The installation can be supplemented with the exhaust
air module NIBE FLM to provide ventilation recovery.
• Pipes and other cold surfaces must be insulated with
diffusion-proof material to prevent condensation.
• The brine system must be supplied with a pressure
expansion vessel. If there is a level vessel this should
be replaced.
P
FREE COOLING
The accessory PCS 44 allows the connection of passive
cooling, for example with fan coils. The cooling system
is connected to the heat pump brine circuit, whereby
cooling is supplied from the collector via a circulation
pump and shunt valve.
• Pipes and other cold surfaces must be insulated with
diffusion-proof material to prevent condensation.
• Where the cooling demand is high, fan convectors
with drip trays and drain connection are needed.
• The brine system must be supplied with a pressure
expansion vessel. If there is a level vessel this should
be replaced.
