This will ensure that your
equipment always operates
reliably!
NOTE
■ Regularly check the function
of the safety valve.
The expansion water amount
at maximum heat (approx. 80°C)
represents approx. 3.5% of the tank
capacity.
When the safety valve test knob is lifted
or in the “Test” position, the water must
flow unhindered out of the safety valve
body into the drainage funnel.
! ATTENTION
This can cause the cold water
supply and parts of the storage
tank connection fitting to become
hot!
1. . Remove the heating flange.
2. Clean the tank.
3. Refit the flange, using a new seal.
Tighten the bolts in a crosswise
pattern to a torque of 20 Nm.
The special enamelled inner tank of
the water heater must not come into
contact with scaling solvent.
Do not use a descaling pump!
4. Thoroughly rinse out the unit.
5. Observe the heating process as per
initial operation.
The installed false anode must
be checked by a specialist at least once
every 2 years of operation and this
inspection must be documented.
If servicing tasks are performed,
the cleaning and servicing flange should
be opened, and the tank inspected for
any infiltration or soiling.
Only with the use of an external current
anode: The control lamp of the external
current anode must be monitored
regularly.
The following applies:
green = system OK
red flashing = malfunction (in this case
contact customer service).
For a faultless function, the tank must
be filled with water.
If the tank is not heated or when warm
water is removed, no water should
be dripping from the safety valve.
If this does occur, either the pressure
in the water pipe is greater than
the permitted value or the safety valve
is defective. If the pressure in the water
pipe is higher than permitted, a pressure
relief valve must be used.
In hard water areas, the limescale which
forms in the tank internal boiler and
the floating deposits of limescale must
be removed by a specialist after one
to two years of operation. Cleaning is
performed through the flange opening.
