2. Operation Instruction for the user and the qualied installer
2.5 First Operation
The water heater should first be oper-
ated by an expert technician only.
Before turning on the water
heater to start operation, turn
the ELCB Reset knob to the ”off” posi-
tion, and open all of water valves fully
at every point, so that water is able to
flow through the heater and expel air
from the pipe and the tank, until the
water flow is constant. Please ensure
that the water heater is functioning
correctly, and close the valve again.
- Turn the ELCB Reset knob to the “on”
position to start operating the water
heater.
- The indicator light will show.
- The DHC_EC / EL Water Heater fea-
tures a temperature control knob at the
front of the unit, whereby 3 tempera-
ture levels may be selected.
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 scald-
ing hazard.
The appliance is not to be installed
in locations where freezing can
occur.
If the supply cord is damaged,
it must be replaced by the
manufacturer, its service agent or
similarly qualified persons in order to
avoid a hazard.
2.6 Adjusting Water Flow
If the required temperature is not
reached, you may adjust the flow rate
by turning the combination valve or
water flow control device (Fig 7 No.8).
The hot water temperature
depends on the power of the
unit, the cold water temperature and
the flow volume.
