3.4.3 To fill the domestic hot water tank
For installation instructions, see the installation manual of the
domestic hot water tank.
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.

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 the chapter Commissioning. This function
should be used to purge the heat exchanger coil of the
domestic hot water tank.
DANGER: RISK OF ELECTROCUTION
WARNING
Always use multicore cable for power supply cables.
INFORMATION
When installing field supply or option cables, foresee
sufficient cable length. This will make it possible to
remove/reposition the switch box and gain acces to other
components during service.
