Operation Instruction for the user and the qualied installer

2. First Operation

Before turning on the water
heater to start operation open all
of water valves fully at every point, so that
water is able to ow through the heater
and expel air from the pipe and the tank,
until the water ow is constant. Please
ensure that the water heater is functioning
correctly, and close the valve again.

WARNING:
When selecting an appropriate
water temperature, the temperature may
be dangerously high, especially for children.
Keep away from the hot water outlet, as it
may cause a potential scalding hazard.

- The indicator light will show.

- The DHCE.../50 Water Heater fea­tures a temperature control knob at the
front of the unit, whereby 3 temperature
levels may be selected.

2.1 Adjusting Water Flow

If the required temperature is not
reached, you may adjust the ow rate by
turning the combination valve or water
ow control device (Fig. 2, No.12).

This appliance is designed for
domestic use. It can be used safely by
untrained persons. The appliance can also
be used in a non-domestic environment,
e.g. in a small business, as long as it is used

in the same way.

Warning Injury
The appliance may be used by

children aged 8 and up and persons with
reduced physical, sensory or mental
capabilities or a lack of experience provided
that they are supervised or they have
been instructed on how to use the
appliance safely and have understood the
resulting risks. Children must never play
with the appliance. Children must never
clean the appliance or perform user main­tenance unless they are supervised.

The hot water temperature
depends on the power of the
unit, the cold water temperature and the
ow volume.
