equipped, upstream of the appliance, with a bipolar cut-out device (minimum
contact distance of 3 mm fuse, breaker switch). In the case where hydraulic
connections are in insulated material, electrical circuits shall be protected by
a differential circuit breaker 30 mA adapted to local standards.
Thermal circuit breaker
(see drawings section 3 page 93): All our products are
equipped with a thermostat with thermal circuit breaker and manual resetting which
cuts off the power supply to the water heater in case of overheating. If the safety trips:
switch off the power before taking any further action,
remove the cover,
check the electrical connections,
reset the thermal circuit breaker.
If the circuit breaker keeps tripping, replace the thermostat. Never short circuit the
safety cut out or the thermostat. Connect the power supply only via the terminal.
SET-UP & OPERATION
EN
-
CAUTION!
NEVER POWER THE WATER HEATER WITHOUT WATER: Models
with an electric heating element will be certainly damaged.
- Fill the tank completely. Before powering up, open the hot water taps, drain
the pipes in order to empty the air.
- Check the tightness of the tubes and of the flange seal under the plastic cover. In case
of leaking tighten moderately. Check the operating of the hydraulic components
and of the safety valve.
- Turn the power on. After 15 to 30 minutes, depending on the capacity of the
device, the water should drip from the drain. This is normal and due to the
expansion of water. Check connection leaks and seal. During heating and
according to the water quality, hot water tanks can make a bubbling noise.
This noise is normal and does not indicate any defect of the unit.
1. SETTING KNOB
(See drawings A and C page 94): Manual selection of
temperature setpoint. Position of reference. C is the maximum position of
temperature setting.
2. FROST FREE MODE
(See drawing B page 94): Automatic regulation at frost-
free temperature (7°C), in order to reduce the electric consumption during the
periods of absence of the user.
3. HEATING LIGHT INDICATOR
(See drawing D page 94): Illuminates when
the heating process is on.
