Draining The Apliance; Filling Up; Failures During Operation; The Water Is Cold - ACV GLASS BL Série Notice D'utilisation

DRAINING THE APLIANCE

When it is necessary to drain the appliance:
- Close stopcock A,
- Open the hot water tap (at the wash-bowl or the bath),
- Open the draining tap B and the water will flow out by the draining.

FILLING UP

Close the draining tap B.
Open the stopcock A and where the water is flowing out through the water tap, close it.

FAILURES DURING OPERATION

This appliance has been designed in order to provide you with satisfaction. However, some failures
may occur.

THE WATER IS COLD

Have a professional verify whether the current arrives to the terminals of the thermostat, if not,
please, verify the circuit breakers and the disconnecting switch.
Have the security device on the thermostat verified which is composed of a rearmable system on
the control cabinet, by means of a small-blade flat screwdriver.
Have the heating element verified.
If the boiler is used in the system of "peak hours", have the timer controlled by the competent
service-provider.

THE WATER IS BOILING

(steam is expelled at the taps),
Cut the current immediately and slowly open the hot water taps.
Have the setting and the proper functioning of the thermostat verified.
If the appliance is old, have an electrician to verify whether there is scale deposited.

INSUFFICIENT FLOW OF THE HOT WATER

Make sure that there is no pressure fall in the cold water supply, which, if the check valve does not
close correcly, would let the hot water flow back into the cold water tube.
Have the heating element verified, if it is present, and the proper functioning of the timer within
and outside the "peak hours".

THE SAFETY GROUP LEAKS VIA THE DRAIN HOLE

This flowing out is not an anomaly at the time of heating. Make sure that the evacuation hole of
the valve is properly connected to a draing pipe.

NEVER BLOCK THIS HOLE

If the flowing out is continuous or not during heating, have the supply pressure verified.
If the water is very hard, annually have the heating element cleaned and have the thermostats set
o
to 65 by your installation technician.

WHEN REMOVING THE SCALE FROM THE APPLIANCE

Never remove the scale by means of chemical agents (hydrochloric acid or similar).
Wash the external walls of the buffer tank in order to take off all traces of limestone but never use
metal objects for removing the limestone.
