INSTALLATION
Connection of external brine pump
(only 40 and 60 kW)
Install the brine pump (GP16) according to the circulation pump
manual for connection of incoming brine (EP14-XL6) and (EP15-
XL6) between the heat pump and shut off valve (see image).
60kW 60kW
GP16
Pipe connection (heating medium)
Connecting the climate system
A climate system is a system that regulates indoor comfort with
the help of the control system in F1345 and for example radiators,
underfloor heating/cooling, fan convectors etc.
The pipe connections are on the rear of the heat pump.
Install the necessary safety equipment and shut off valves
(installed as close to the heat pump as possible so that the flow
to individual cooling modules can be shut off).
Fit the supplied particle filter on the incoming pipe.
The safety valve must have a maximum 0.6 MPa ( 6.0 bar)
opening pressure and be installed on the heating medium return.
The entire length of the overflow water pipe from the safety
valves must be inclined to prevent water pockets and must also
be frost-free.
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.
Fit the supplied non-return valves on the outgoing pipe.
Install the vent valves in the climate system if necessary.
CAUTION! When necessary you should install
venting valves in the climate system.
CAUTION! The heat pump is designed so that
heating production can occur with one or two
cooling modules. This however entails different
pipe or electrical installations.
Pipe connection (water heater)
• Any docked hot water heater must be fitted 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 opening pressure in
accordance with the water heater manual and be installed on
the incoming domestic water line. The entire length of the
overflow water pipe from the safety valves must be inclined
to prevent water pockets and must also be frost-free.
CAUTION! The heat pump/system is
designed so that hot water production can
occur with one or several cooling modules.
This however entails different pipe or electrical
installations.
Fixed condensing
If F1345 is to work towards the water heater with fixed condensing you
must connect an external flow sensor (BT25) according to the descrip-
tion in the installer handbook In addition, menu settings must be made
(see installer handbook).
