1 - INSTALLATION
(See General Warnings 1 to 6 p.7)
Installation of vertical wall mounted water-heater: to enable the heating element to be replaced, leave free space in
the front of the water heater.
Installation must be done by qualified / approved personal.
Installation (p3) : Above sink models: see fig. C and fig. 2, Under sink models: see fig. C and fig.3
2 - HYDRAULIC CONNECTION
All water supply pipes must be thoroughly cleaned before connection. The connection of the hot water outlet must be
made using a cast iron or steel sleeve of a dielectric union in order to avoid corrosion of the tubes (due to direct contact
between iron and copper). A brass union must not be used.
Unvented installation (see. fig 9.1 & 9.2): A new safety device complied with the current standards (in Europe EN
1487) must be fitted with a rated pressure of 6 or 9 bar (0,6 or 0.9 Mpa), and dimension 1/2''έ The safety valve must
be protected from frost. No water accessory must be installed between the safety device and the cold water inlet to
the appliance. Connect the safety device to an unpressurised outlet pipe in a frost free environment, with a
continuous slope for the evacuation of the water during heating up or draining the water heater).
Attention: Do not use the safety valve included in this packaging in France (home country and French overseas...)
Vented installation (see fig. 10.1 & 10.2): (Supply for a single water drawing point). The installation must be
equipped with a special mixer tap (not supplied).
Attention: each time the unit heats up, water will flow from the tap. Do not block this flow.
3 - ELECTRICAL CONNECTION
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) 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 applianceέ 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), 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.
