Freezing protection:
When the water heater is not in use for longer periods of time, it should be protected from
freezing by setting the temperature to
. Do not disconnect the power. Thus the temperature
of water is maintained at about 10°C. Should you choose to disconnect the power, the water
heater should be thoroughly drained before the onset of freezing conditions.
Discharging water from the water heater:
Water is discharged from heater via the inlet pipe. To this purpose, a special fitting (T-fitting)
must be mounted between the relief valve and the heater inlet pipe, or a discharge tap.
The heater can be discharged directly through the relief valve, by rotating the handle or the
rotating valve cap to same position as for checking the operation. Before discharge, make
sure the heater is disconnected from the power supply, open the hot water on the connected
mixer tap. After discharging through the inlet pipe, there is still some water left in the water
heater. The remaining water will be discharged after removing the heating flange, through
the heating flange opening
MAINTENANCE
The external parts of the water heater may be cleaned with a mild detergent solution. Do not
use solvents and abrasives.
Regular preventive maintenance inspections ensure faultless performance and long
life of your heater. The first of these inspections should be carried out by the authorized
maintenance service provider about two years from installation in order to inspect the
wear of the protective anticorrosion anode and remove the lime coating and sediment as
required. The lime coating and sediment on the walls of the tank and on the heating element
is a product of quality, quantity and temperature of water flowing through the water heater.
The maintenance service provider shall also issue a condition report and recommend the
approximate date of the next inspection.
Never try to repair any possible faults of the water heater by yourself, but inform
about it the nearest authorized service provider.
