Maintenance

Safety valve
The safety valve must be checked about four times a year.
When the knob for the safety valve is turned anti-clock-
wise, water must stream out of the waste pipe. If this does
not happen then the safety valve is defective and must be
replaced.
The safety valve sometimes releases a little water after hot
water has been used. This discharge is caused by the ex-
pansion through heating of cold water entering the water
heater, resulting in a pressure increase, whereby the safety
valve opens.
Emptying
Empty the water heater as follows:
1. Switch off the current to the water heater by setting
the circuit breaker (2) to "0".
2. Open the shut-off valve (22) (turn anticlockwise).
3. Open the mixer valve (25) fully (turn anticlockwise).
4. Open the safety valve (23) (turn slowly anticlockwise
until it remains in the raised position).
NOTE
Draining is through the safety valve overflow
pipe. Beware of any water splashes.
5. Open a hot water tap, preferably the closest and low-
est, to let air into the system. If this is not sufficient,
loosen a pipe coupling marked HW on the mixer valve.
For faster drainage slacken off the vacuum valve (84) a
couple of turns. Some water will run out at the valve.
Dealing with malfunctions
NOTE
Electrical installation and service must be carried out
under the supervision of a qualified electrician.
If the power cable is damaged, in order to prevent a
hazard it must be replaced by the manufacturer, its
authorised service agent or other qualified person.
Check the installation's fuses as well as the thermostat and
mixer valve settings.
Check the external solar panel equipment.
Wait a few hours without hot water usage and then check
whether the temperature level has risen. If there is still no
hot water, contact the installation engineer.
