3. ELECTRICAL CONNECTION
For electrical connection, refer to drawing section 3 pages 75-76.
- The water heater can be connected and operated only on AC 220-240 V. Connect the heater
with a rigid cable with conductors 2,5 mm². Use a standardised channeling (rigid or flexible
conduit) until the calibrated housing cover.
- Directly connect devices with a cable or plug. In France, a product with plug is strictly
prohibited and cannot be installed.
- Always connect the earth conductor of the cable to the earth ground wire or connect the
earth conductor to the appropriate terminal identified by the symbol . This connection
is compulsory for safety reasons. The earth wire green - yellow must be longer than those
of phases. The installation must be 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 connexions are in insulated material, electrical circuits shall be protected by
a differential circuit breaker 30 mA adapted to local standards.
Thermal circuit breaker (see drawing section 3 pages 75): 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 and 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. POWER ON LIGHT This light indicates that there is power in the active parts in the
appliance. The power light is not dependent on the status of the safety thermostat. Whenever
there is electricity supplied to the device, this light will stay on.
2. HEATING LIGHT This light indicates that the water heater is heating water and that the
heating element is in operation.
