Part
Isolation of water inside the house when there is a power
c
interruption. Normally closed valves (located indoors near the
piping entry/exit points) can prevent that all water from indoor
piping is drained when the freeze protection valves open.
▪ When there is a power interruption: The normally closed valves
close and isolate the water inside the house. If the freeze
protection valves open, only the water outside the house is
drained.
▪ In other circumstances (example: when there is a pump failure):
The normally closed valves remain open. If the freeze protection
valves open, the water from inside the house is also drained.
NOTICE
When freeze protection valves are installed, set the minimum cooling setpoint
(default=7°C) at least 2°C higher than the maximum opening temperature of the
freeze protection valve. If lower, freeze protection valves can open during cooling
operation.
To fill the water circuit, use a field supply filling kit. Make sure you comply with the
applicable legislation.
NOTICE
The unit contains an automatic air purge valve. Make sure it is open. All automatic air
purge valves in the system (in the unit, and in the field piping – if any) must remain
open after commissioning.
See the installation manual of the domestic hot water tank.
The piping in the complete water circuit MUST be insulated to prevent
condensation during cooling operation and reduction of the heating and cooling
capacity.
Outdoor water piping insulation
NOTICE
Outside piping. Make sure the outside piping is insulated as instructed to protect
against hazards.
For piping in free air, it is recommended to use the insulation thickness as shown in
below table as a minimum (with λ=0.039 W/mK).
