■The area where F1245PC 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 elim-
inate 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. The panels do not need to be
removed during service, all service on F1245PC 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
transmission of vibrations.

System diagram
F1245PC consists of a heat pump, water heater, elec-
trical module, circulation pumps and a control system.
F1245PC 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 the water
heater. If there is a greater need for heating/hot water
than the compressor can provide there is an integrated
immersion heater.
The brine can also be circulated via a mixing valve to a
heat exchanger. There the brine cools the heating sys-
tem's water so that comfort cooling can be maintained
during the hotter periods of the year.

Applies to PEM hose 40x2.4 PN 6.3.
These are rough example values. At installation the
correct calculations must be made according to local
conditions.
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).
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.
As the temperature of brine system can fall below 0 °C
it must be protected against freezing down to -15 °C.
1 litre of ready mixed brine per meter of collector hose
(applies when using PEM-hose 40x 2.4 PN 6.3) is used
as a guide value when making the volume calculation.
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).
* Can be angled for side connection.
17Chapter 4 | Pipe connectionsNIBE™ F1245PC

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 supplied safety valve under the level vessel
as illustrated. The entire length of the overflow water
pipe from the safety valves must be inclined to pre-
vent water pockets and must also be frost proof.
■Install shut off valves as close to the heat pump as
possible.
■Fit the supplied particle filter on the incoming pipe.
In the case of connection to an open groundwater
system, 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 F1245PC
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.
■The safety valve must have a maximum 0.25 MPa (2.5
bar) opening pressure and be installed on the heating
medium return as illustrated. The entire length of
the overflow water pipe from the safety valves must
be inclined to prevent water pockets and must also
be frost proof.
■When connecting to a system with thermostats on
all radiators, a relief valve must be fitted, or some of
the thermostats must be removed to ensure sufficient
flow.

Water heater
Connecting the hot water heater
■The hot water heater in the heat pump must be
supplied with necessary set of valves.
■The mixing valve must be installed if the setting is
changed so that the temperature can exceed 60 °C.
■The setting for hot water is made in menu 5.1.1.
■The safety valve must have a maximum 1.0 MPa (10.0
bar) opening pressure and be installed on the incom-
ing domestic water line as illustrated. The entire
length of the overflow water pipe from the safety
valves must be inclined to prevent water pockets and
must also be frost proof.
Docking alternatives
F1245PC can be connected in several different ways,
some of which are shown below.
Further option information is available at www.nibe.eu
and in the respective assembly instructions for the ac-
cessories used. See page 64 for a list of the accessories
that can be used with F1245PC.
NIBE™ F1245PCChapter 4 | Pipe connections18

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.
UKV
P
Extra electric hot water heater
The heat pump should be supplemented with an elec-
tric water heater, for example NIBE COMPACT, if a
whirlpool or other significant consumer of hot water
is installed.
■The valve connection on COMPACT can be separated.
The mixing valve remains on COMPACT and the re-
maining valve connector can be used for incoming
cold water in F1245PC.

HW
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
suitable value to prevent freezing in the heat ex-
changer.
Ventilation recovery
The installation can be supplemented with the exhaust
air module 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 (CM3). If there is a level vessel (CM2)
this should be replaced.

Two or more climate systems
When more than one climate system, with a lower
temperature, is to be heated up, the following connec-
tion can be used. The shunt valve lowers the temperat-
ure to, for example, the under floor heating system.
The ECS 40/ECS 41 accessory is required for this con-
nection.
Pool
Charging of the pool is controlled by the pool sensor.
In the case of low pool temperatures, the shuttle valve
reverses direction and opens towards the pool ex-
changer. The POOL 40 accessory is required for this
connection.
