COMMISSIONING

Before the device is switched on electrically, the storage tank must be filled with water.

The expansion water produced in the interior tank during heating must drip from the safety valve (pressure

resistant connection), respectively from the overflow mixer tap (pressureless connection).

Caution: First-time heating must be performed and supervised by a licensed professional. The hot

water drainpipe and parts of the safety fitting may get hot.

After heating, the set temperature and the actual temperature of the retrieved water should be approxi-

mately the same.

DECOMMISSIONING, DRAINING

If a water heater is shut down or not used for an extended period of time, it must be emptied and com-

pletely disconnected from the electrical power supply. Switch off supply line switch or circuit breakers.

In rooms where there is a permanent risk of frost, the water heater has to be emptied before the start of

the cold season if the device is not used for several days and if it is not operated in frost protection mode.

Once the stop valve in the cold water supply line has been closed, the water is drained through the drain

valve of the safety valve combination. Simultaneously, all hot water valves of the connected fittings are

opened. Draining is also possible through the safety valve into the expansion water funnel (drip catcher).

To do this, the safety valve wheel must be brought to "test" position.

Caution: Hot water may flow out during the draining procedure.

If there is a risk of frost, do not forget that not only the water in the water heater and in the hot water

lines may freeze, but also in all cold water supply lines to the fittings and to the device itself. Therefore,

it makes sense to drain all water-carrying fittings and pipelines (including the heating circuit = bare-tube

heat exchanger) all the way back to the frost-proofed part of the domestic water system (domestic water

connection).

If the storage tank is re-commissioned, it is absolutely necessary to ensure that it is filled with water

and that bubble-free water comes from the hot water valves.

CHECKING, MAINTENANCE, CARE

a) During heating, the expansion water must drip visibly from the drain of the safety valve (in case of a

pressureless connection, the expansion water drips from the valve of the mixer tap). If the device is fully

heated (approximately 85°C), the volume of the expansion water is approximately 3.5% of the content

of the storage tank.

The function of the safety valve must be checked regularly. When the safety valve check button is lifted

or turned to the "test" position, the water must flow freely from the body of the safety valve into the

drain funnel.

Caution: The cold water inlet and parts of the storage tank connection fitting may get hot in the pro-

cess. If the water heater is not heated, no water should drip from the safety valve. If water does drip

from the safety valve, either the pressure in the water line is too high (above 5.5 bar: fit a pressure re-

ducing valve), or the safety valve is defective. Please call the installation expert immediately!
