Connecting the climate system
■
Connect HM 8-12 SPLIT pipe connections (XL1) and (XL2)
to the climate system.
NOTE
The term "Climate system" which is used in these in-
stallation and maintenance instructions regards
heating or cooling systems from HM 8-12 SPLIT for
heating or cooling.
Connecting the hot water heater
The water heater (WWS 300 SPLIT/WWS 500 SPLIT) must
be supplied with the necessary set of valves.
■
There must be a mixer valve if the temperature exceeds
60 °C.
■
The safety valve must have a maximum 10.0 bar opening
pressure and be installed on the incoming domestic
water line according to outline diagram. The entire
length of the overflow water pipe from the safety valves
must be inclined to prevent water pockets and must also
be frost proof.
■
See section Dockings on page 29 for outline diagram.
Extra water heater with immersion heater
The heat pump should be supplemented with an electric
water heater, if a hot tub or other significant consumer of
hot water is installed.
If the water heater is equipped with a valve connector Ø
15 mm this should be replaced with a corresponding Ø 22
mm.
