IMPORTANT
Water supply uti lity must have necessarily installed
safety valve which will protect against excessive in-
crease of pressure.
IMPORTANT
Do not use the heater if there is a blockage of the safe-
ty valve.
IMPORTANT
Installation of any narrowing (e.g. reducers, filters etc.)
and shut-off valves between the heater and the safety

The HT 6Split / HT 12Split unit is not equipped with a
shut-off valve for the central heating system, hot water
system or electric additional heat; these must be in-
stalled on the outside of the indoor unit to facilitate any
future servicing.
The hot water tank should be connected to a water
supply system with water pressure of min. 1 bar,
max. 10 bar. If the pressure at the cold water inlet to
the tank is higher than the permissible level, use a
pressure reducer. During heating of the water in the
tank, the pressure increases, which is why each tank
must be equipped with the appropriate safety valve,
installed on the cold water supply, which will protect
the tank against an excessive increase in pressure.
If using hot water circulation, see subsection “DHW
circulation”.
