Caution
Make sure that the water heater is filled with water before you turn on the water heater.
Switch the isolator between the water heater and the mains power supply on to start the
water heater.

Temperature setting

Warning
Only qualified service engineers are allowed to change the set temperature.

Turn off the water heater

Turn off for a short period

To turn off the water heater for less than 2 months, set the water heater in the OFF mode
(see 3.2.1).
Note
If the water heater stays in the OFF mode for more than 2 months and no water is
drained, air bubbles may be formed in the water heater. This can lead to air in the water
pipes.

Turn off for a long period

When the water heater needs to be turned off for more than 2 months, contact your
service and maintenance engineer to decommission the water heater.
