If the standard initial pressure in the expansion vessel
is too low, this can be increased by filling it via the
installed valve. The expansion vessel’s standard initial
pressure must be entered in the checklist on page 5.
Any change in the initial pressure affects the ability of
the expansion vessel to handle the expansion of the
heating medium.
CAUTION
In order to obtain the minimum undisturbed flow in
the climate system, use the appropriate hydraulic solu-
tions (e.g. relief valve, low loss header, parallel buff-
er and/or open heating loops). Remember to always
maintain the minimum required flow in the system -
see the subsection “Minimum system flow”.
CAUTION
The term “climate system” which is used in this instal-
lation and user manual signifies heating and cooling
operation systems that are supplied with heat or cold
using heating or cooling medium from the HM 6Split /
HM 12Split unit, for heating or cooling purposes.

Minimum climate system volumes
The heat pump installation requires an appropriate
volume of heating medium (approx. 10l/kW heat
pump power) and a minimum, undisturbed flow.
In case of an insufficient amount of heating medium
in the installation, an additional buffer vessel must be
used, which will ensure adequate system volume,
see subsection “Minimum climate system volumes”.
An insufficient flow in the central heating system will
cause malfunction of the heat pump installation and
could lead to serious damage of the product.
