Connecting the water piping
3.4.1 To connect the water piping
NOTICE
Do NOT use excessive force when connecting the piping.
Deformation of the piping can cause malfunctioning of the
unit.
To facilitate service and maintenance, 2 shut-off valves are provided.
Mount the valves on the water inlet and on the water outlet. Mind their
the position. Orientation of the integrated drain and fill valves is
important for servicing.
1
Install the shut-off valves on the water pipes.

NOTICE
It is recommended to install shut-off valves to domestic cold
water in and domestic hot water out connections. Shut-off
valves are field supplied.
2
Screw the indoor unit nuts on the shut-off valves.

3.4.2 To fill the water circuit
1
Connect the water supply hose to the fill valve.
2
Open the fill valve.
3
Make sure that the automatic air purge valve is open (at least 2
turns).
INFORMATION
For location of the air purge valve, see Installer reference
guide, Components: Indoor unit.
4
Fill the circuit with water until the manometer indicates a
pressure of ±2.0 bar.
5
Purge as much air as possible from the water circuit.
NOTICE
Air in the water circuit can cause malfunctioning of the
backup heater. During filling, it may not be possible to
remove all the air from the circuit. Remaining air will be
removed through the automatic air purge valves during
the initial operating hours of the system. Additional filling
with water afterwards may be required.
To purge the system, use the special function as
described in To perform an air purge. This function
should be used to purge the heat exchanger coil of the
domestic hot water tank.
6
Close the fill valve.
7
Disconnect the water supply hose from the fill valve.
3.4.3 To fill the domestic hot water tank
1
Open every hot water tap in turn to purge air from the system
pipe work.
2
Open the cold water supply valve.
3
Close all water taps after all air is purged.
4
Check for water leaks.
5
Manually operate the field installed pressure relief valve to
ensure that free water flow through the discharge pipe.
3.4.4 To insulate the water piping
The piping in the complete water circuit must be insulated to prevent
condensation during cooling operation and reduction of the heating
and cooling capacity.
If the temperature is higher than 30°C and the humidity is higher than
RH 80%, the thickness of the sealing materials should be at least
20 mm to prevent condensation on the surface of the sealing.
