Hot water tank
Connections overview
The scalding fuse is delivered together with the unit and must be installed by a plumber.
Connection “RS”
The efficient foam insulation protects against unnecessary heat loss.
All connection nozzles for water are 3/4" threaded and are located in the bottom of the tank.
The hot water tank is equipped with a 1.5 kW supplemental electric heating which is deactivated by default and must be activated via
the control panel if required.

If there is a desire to install an expansion vessel to prevent the
safety valve from draining water from the tank during heating, in-
stall it on the cold water side - remove the flanged blanking plug (8)
and connect.
This expansion vessel must have a pre-pressure of 5 bar and must
be suited for domestic water. It is also possible to mount the ex-
pansion vessel on the hot water side.
ATTENTION
All work must be carried out by qualified personnel and in compliance with existing legislation and regulations.
ATTENTION
The supplemental electric heating must not be activated before the water tank is filled with water.
