2. INSTALLATION
- Refer to the corresponding diagrams p.1 & 2 (see table on
right):
- Make sure to keep free space of 300 mm below pipes for the
exchange of the heating element.
3. HYDRAULIC CONNECTION
- It is necessary to clean the supply piping prior to the hydraulic connection. The connection to the hot water outlet is to be
carried out with a cast iron or steel sleeve or a dielectric connector, to avoid corrosion of the pipe (direct contact iron /
copper). The use of brass fittings is prohibited.
INSTALLATION PRESSURISED: See fig. ❸, p.2. Always install a new safety device on the cold water pipe of the
water heater.
- During heating up, water dripping may occur at the valve, do not obstruct the dripping. The safety device if
supplied does not meet the criteria for installation on French territory (Mainland and Overseas territories), do not use
it.
4. ELECTRICAL CONNECTION
Refer to the corresponding diagrams p.3 (See fig. ❹ & ❺
-
- The water heater can be connected and operated only on AC 230V or on AC 220-240V in accordance with the rating
plate of the appliance. Connect the heater with a rigid cable with conductors 2,5mm². Use a standardised channeling
(rigid or flexible conduit) until the calibrated housing cover.
- Directly connect devices with a cable , or plug. (Forbidden in French territory)
- 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
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
connections are in insulated material, electrical circuits shall be protected by a differential circuit breaker 30 mA
adapted to local standards.
- Thermal circuit breaker: All products are equipped with a thermostat including a thermal circuit breaker with manual
reset, which cuts the power in case of overheating. In case the security trips A: Cut the power before any operation.
B: remove the plastic cover. C: Check the electrical connection. D: Reset security. In case of repetitive tripping, replace
the thermostat. Never bypass safety or regulation thermostat. Connect the power only on the sockets or thermostat
input.
5. STARTING UP
- 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 of 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.
If you see a continuous release of steam or hot water from the drain or when opening a faucet, turn off
immediately the power to the water heater and call a professional.
