This ensures the operational reli-
ability of your equipment!
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 turned to 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 sup-
ply 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.
In the process, 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.
