Safety devices
The domestic hot water tank relief valve connections
may not be used for other purpose.
This domestic hot water tank can only be used with an
RKHBRD indoor unit.
Thermal protector — The RKHBRD indoor unit is equipped with
a thermal protector. The thermal protector is activated when the
temperature becomes too high. When activated, the protector
has to be reset on the indoor unit by pressing the red button (for
access, remove the decoration panels like indicated in the
manual of the indoor unit).
Switch off the power supply before opening the
decoration panels of the indoor unit.
Pressure relief valve — A pressure relief valve (field supply) in
accordance with relevant local and national regulations, and with
an opening pressure of maximum 10 bar must be connected to
the pressure relief valve connection.
If a discharge pipe is connected to the pressure relief device it
must be installed in a continuously downward direction and in a
frost-free environment. It must be left open to the atmosphere.
