3 - ELECTRICAL CONNECTION
Warnings 7/8/9 and 15 p.10 & 11)
The water heater can be connected and powered only by a single-phase 220 - 240V~ mains supply. Connect the water
heater via a fixed duct with a cross section of 2.5 mm
calibrated receptacle in the cover. For appliances supplied with a cable or a plug (prohibited in France and Singapore)
connect up directly.
The earthing conductor must be connected to earth or lead the earth wire to the terminal provided indicated by the
symbol . This connection is absolutely necessary for safety reasons. The green/yellow earth lead must be longer
than the two live wires. Installation must include upstream of the appliance, an all pole cut-out device (contact opening
at least 3 mm: fuse, breaker switch). When the water pipes are made of insulating material, the electrical contacts must
be protected by a 30 mA earth-leakage breaker conforming to the standards in force.
Thermal circuit breaker: 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. Warning: If the safety trips a) switch
off the power before taking any further action, b) remove the cover, c) check the electrical connections, d) reset the
thermal circuit breaker. If the circuit breaker keeps tripping, replace the thermostat or/and thermal circuit breaker. Never
short circuit the safety cut out or the thermostat. Connect the power supply only via the terminal.
4 - SETUP & OPERATION
WARNING: Never switch on the water heater without water. Before switching on, open the hot water taps, vent the
pipes of air and fill the appliance.

Check the water tightness of the pipe work and the door seal below the cover. In case of a leak, tighten slightly.
Check that the water safety devices are working and fill the drain.

Switch on the appliance. The orange light B1 (see fig. B for square product p.2) or light 2 (see fig. A/B p.4 for
horizontal product)) will come on. It will switch off when the water has been heated to the set temperature.
Note: After 15 – 30 minutes, depending on the capacity of the appliance, water should drip from the drain hole. This
phenomenon is due to water expansion and is normal. Check the water tightness of the joints and the seal.
During heating and depending on water quality, room-sealed water heaters can produce a boiling noise; this is normal
and does not indicate any defect on the appliance. To avoid the development of bacteria (legionella...) ensure that a
temperature of 60°C minimum is reached every day. The thermostat is set at the factory at the stop (65°or 75C±5°C).

Adjusting the temperature: for models equipped with a regulation knob B2 (see fig. B square product) or light
1 (see fig. A/B p.4 for horizontal product), it is possible to adjust the temperature set point by rotating the
external knob. The minimum position corresponds to the anti-freeze function.
IMPORTANT: If steam or boiling water emerges continuously from a supply tap or a drain valve, switch off the electricity
to the water heater or boiler and call a professional plumbing contractor.
5 - MAINTENANCE
(See General Warnings 9, 11,15 and 17 p.10 & 11)
CAUTION: Before removing the plastic cover, make sure the power is turned off to avoid any risk of injury or electric
shock
 User maintenance: Operates once a month the discharge of the water safety device to prevent scaling and
verify that it is not blocked. If this is not done, damage may be caused and the guarantee invalidated. For an
installation with a booster pump; before starting up, after a long period of disuse, turn the rotor following the advice in
the manufacturer's instructions.
 Maintenance by a qualified person:
1/ Remove the scale sludge. Do not scrape or hammer the lime scale deposited on the casing, as this may damage
the lining.
2/ Change the magnesium anode every 2 years or when its diameter is lower than 10 mm.
3/ Changing the shielded heating element or the anode requires the water heater to be drained and the joint changed.
DRAIN: Switch off the power and cold water and open the hot water taps before carrying out these operations. Refit
the heating element and tighten the screws smoothly (opposite screws in sequence), check for leaks the next day and
tighten if required.
If the supply cord is damaged, it must be replaced by a special cord or assembly available from the manufacturer or
its service agent.
Spare parts list: thermostat, thermal circuit breaker, joint, heating element, pilot light, the magnesium anode, the
connection cable. The guarantee requires genuine manufacturer's parts to be used.
Advice to the user: When the water has a TH > 20°f, it is recommended that this be treated. When a softener is used,
the water hardness must remain above 15°f. In case of prolonged absence, especially in winter, drain your appliance
following the procedure.
