3. FOR THE USER
Installing and putting into operation the
heater for the first time will have to be done
by an authorized installer.
3.1 Instructions for use
Operating procedure:
1. Check whether the heater is filled with
water.
2. Turn on the main switch, whenever there
is a fixed connection or put the plug into
the socket.
3.2 Use
The heater is under the pressure of the water
supply (max. 8 bar). The quantity of cold
water being supplied, will exactly correspond
to the one of the consumption of hot water.
The regulating thermostat will switch on the
electric supply, automatically. This implies
that the electric circuit will be shut and heat
supplied to the water, whenever the
temperature is inferior to the demanded one.
The electric circuit will be interrupted again,
at the moment the demanded temperature
will be reached.

In view of the limitation of the precipitation of
calcium, it will be recommendable to adjust
the temperature at 60 °C. Besides, a safety
thermostat will be fitted, interrupting
completely the electric circuit, the water
temperature having reached 95 °C. After this
temperature will have fallen by 20 °C, the
thermostat can be reset, again. In the case of
another intervention of the safety thermostat,
with the regulating thermostat being adjusted
at a high temperature, this last one will have
to set at a lower temperature. If there will still
be another intervention of the safety
thermostat, the regulating one will probably
be out of order.
3.3 Putting out of operation
Operating procedure:
1. For short periods: Remove the plug from
the socket or, with a fix connection, turn
off the main switch.
2. For longer periods it will be
recommendable, in view of the danger of
frost, not only take the measures
indicated sub 1, but also turn off the
water supply pipe and, after the heater
will have cooled down, drain the water
(connect a drain hose on the drain tap
and open it). Also, open the nearest hot
water tap drain, so that the tank can be
ventilated. If there is the intention to
totally empty the heater, uncouple it and
let it slope in the direction of the drain
tap.
3.4 Maintenance
Regularly test the inlet combination by
discharging it (activate the discharge button).
The water must come out of it as a thick jet:
Check, whether the drain pipe is open. It will
be recommendable to sign a contract, based
on a maintenance, once a year.
When ordering spare parts, it will be
necessary to specify the type of apparatus
and the complete serial number. Thereby, the
data of the spare parts can be determined.
3.5 In case of failures
Whenever there is a failure, do switch off the
water heater by means of turning the main
switch and call for help by an authorized
service engineer.
