8 Maintenance

All maintenance must be operated by a quali ed personnel.
Before contacting the customer service, make sure the suspected failure
is not caused by a temporary lack of water.
To discharge the water completely from the tank, remove the safety valve
from the water heater. Before removing the valve, the power of the heater
should be switched o so that the tank can cool down (outlet connection
must also be disconnected).
The magnesium rod is cosumable. We suggest having a check every six
months and replace it if needed.

9 Electrical connection

The electrical connection must be done by a quali ed electrician.
The electrical supply is connected directly to the connector with the
earth connection. The ground wire must be green/yellow in colour
and attached to the terminal marked by the symbol.
The heater must be connected to the electricity supply which is out of
reach from the person using the shower.
All wiring must conform to local requirements. If any doubts, please consult
a quali ed electrician.
Note: All plumbing must be connected before electrical connections. Fill the
tank with water and then turn on the tap to release water out of the tank
until all the air has been expelled out. Plug in after the water tank is full of
water again.
