3. FOR THE USER
3.1 Instructions for use
3.1.1 Advice
Installingandputtingintooperationtheheaterfortherst
time will have to be done by an authorised installer.
3.1.2 Filling of the heater
Operating procedure:
I. Checkwhethertheheaterislledwithwater.
2. Open the cold water tap in the direction of the heater,
as well as all the taps of hot water drains, for the
purposeofventilation.Theheaterwillbelled,as
soonascoldwaterisowing,ateverydraintap.
3. Again, turn off all the taps of hot water drain taps.
3.2 Putting into operation
Operating procedure:
1. Checkwhethertheheaterislledwithwater.
2. Turnonthemainswitch,wheneverthereisaxed
connection or put the plug into the socket.
3.3 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.
Temperature in °F Temperature in °C
90 32
100 38
110 43
120 49
130 54
140 60
150 66
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tted,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.
3.4 Putting out of operation
Operating procedure:
I. For short periods: Remove the plug from the socket
or,withax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.
3.5 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, wheter 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.
Important advises:
The heater must NEVER be put into operation,
with the cold water supply being shut off.
In the course of maintenance, the heater must
not be under tension.
