Pipe installation
General
Pipe installation must be carried out in accordance with
current norms and directives. HM 8-12 SPLIT can work at
a temperature up to 65 C. For best savings, we recommend
that the climate system be dimensioned for max 55 C.
HM 8-12 SPLIT is not equipped with shut-off valves. These
must be installed outside the indoor module to facilitate
any future servicing.
HM 8-12 SPLIT can be connected to the radiator system,
floor heating system and/or fan convectors.
Overflow valve
NOTE
A free flow is required for all docking options, which
means that an overflow valve must be installed.
System requirements
This is required for minimum configuration:
For correct function the volume of the climate system must
comply with the installation requirements, see page 29.
If this is not fulfilled a volume vessel needs to be installed.
WPSK 40SPLIT/WTPSK 100SPLIT.
For more options, see the docking description on page 29.
