NOTICE
▪ Air in the water circuit can cause malfunctioning. 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 "6 Commissioning" on
page 20 . This function should be used to purge the
heat exchanger coil of the domestic hot water tank.
4.4.3 To fill the domestic hot water tank
For installation instructions, see the installation manual of the
domestic hot water tank.
4.4.4 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 insulation materials should be at
least 20 mm to prevent condensation on the surface of the
insulation.
When the drain pan is installed, make sure to insulate the water
piping up to the drain pan to avoid condensation.
