2. Open the hot tap in the bathroom or
kitchen with pre-selecting mixing taps or
single lever fittings set to hot.
3. Switch on power for water pump (control
panel). Leave the tap open to let air
escape while the water heater is filling.
The heater is filled when water flows out
of the tap.
Residues of frozen water can prevent
filling if there is a frost. The water heater
can be defrosted by switching on the
heater for a short period (max 2 mins).
Frozen pipes can be defrosted by heating
the room.
Note: If just the cold water system is being
used, without water heater, the heater tank
is also filled up with water. In order to avoid
damage through frost, the water contents
must be drained by actuating the
safety/drain valve, also when the heater has
not been used. As an alternative, two shut-
off valves, resistant to hot water, can be
fitted in front of the cold and hot water
connection.
Draining the water heater
1. Disconnect power for water pump
(control panel).
2. Open hot water taps in bathroom and
kitchen.
3. Open safety/drain valve: Lever in vertical
position, position (f).
4. The water heater is now drained directly
to the outside via the safety/drain valve.
Check that the water contents have been
completely drained (10 litres).
Gas operating instructions
Attention: Never operate the water heater
without water in it!
If the wall cowl is positioned close to an
opening window (or hatch) - in particular
directly under it - it must remain closed
when the water heater is in use (see
warning plate).
1. Remove cowl cover.
2. Open gas cylinder and open quick-acting
valve in the gas supply line.
3. Switch the water heater on at the rotary
switch (a) of the control panel, and the
green monitor lamp will light up. Set the
desired water temperature at the rotary
knob (c) (steplessly adjustable from about
30°C to 70°C).
4. If there is air in the gas supply line, it may
take up to a minute before the gas is
available for combustion. If the appliance
switches to “Failure“ during this period,
switch off the appliance - wait 5 minutes -
and switch on again!
