You can find a list of compatible products in the section
"Compatible indoor modules (VVM) and control modules
(SMO)".
Caution
There is a difference between connection to a
control module compared with connection to an
indoor module.
See the Installer Manual for the indoor module/con-
trol module.
Vent the heat pump by the "heating medium supply" con-
nection (XL1) using the venting nipple on the enclosed flex-
ible hose.
Install as follows:
• expansion vessel
• pressure gauge
• safety valves
• drain valve
For draining the heat pump during prolonged power fail-
ures.
• non-return valve
Installations with only one heat pump: a non-return valve
is only required in those cases where the placement of
the products in relation to each other can cause self-cir-
culation.
Cascade installations: each heat pump must be fitted with
a non-return valve.
• charge pump
• shut-off valve
To facilitate any future servicing.
• enclosed filterball (QZ2)
Installed before connection "heating medium return" (XL2)
(the lower connection) on the vacuum pump.
• reversing valve.
When connecting to the control module, and if the system
is to be able to work with both the climate system and the
hot water heater.
