Installation manual
INSTALLATION (Figure 1 page A)
It is compulsory to fit a sump below the water heater if mounted in a suspended ceiling, under the roof or above living area. A drain connected to the
sewer is required.
LOCATION
INSTALLATION OF A VERTICAL WATER HEATER (Figure 2 page A)
To enable the heating element to be replaced, leave free space below the ends of the tubes of the appliance. The appliances can be mounted on a tripod
(optional) if the wall is not strong enough. It is, however, obligatory for the upper bracket of the water heater to be attached to the wall to prevent
it tilting.
INSTALLATION OF A STABLE WATER HEATER (Figure 3 page A)
The water heater must be installed absolutely vertically in such a way as to ensure perfect stability with access to its electrical parts and safety devices.
Allow for access to parts which may need replacing.
INSTALLATION OF A HORIZONTAL WATER HEATER (Figure 4 page A)
Various ways to install ; when the water heater is in place, the water connections MUST be absolutely vertical below the appliance. Allow for access to
parts which may need replacing.
WATER CONNECTIONS (Figure 5 page B)
All water supply pipes must be thoroughly cleaned before connection. The connection to the hot water outlet must be made using a cast iron or steel
sleeve or 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:
A new safety device which conforms to current standards (in Europe EN 1487), pressure 0,7 and 0,9 MPa (7 and 9 bar) and size 3/4'' in diameter must
be fitted. The safety valve must be protected from frost.
Hydraulic accessories should not be located between the safety valve and the cold water inlet. A pressure reducer (not supplied) is required when
the water supply pressure exceeds 0,5 MPa (5 bar) and will be fitted on the main supply.
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. The pipes used must support 1 MPa (10 bar) and 100°C.
If using PER pipes, we strongly recommend that a thermostatic regulator be fitted to the water heater outlet. It will be set according to the performances
of the equipment used.
ELECTRICAL CONNECTIONS (Figure 6 page D and E)
The water heater can be connected and powered only by a single-phase 230 V AC or a three-phase 400 V mains supply according to model. Connect
the water heater via a fixed duct with a cross section of 2.5 mm². Use a standard duct (fixed or ring reinforced sheath) to the calibrated receptacle
in the caver. In the case of appliances fitted with a cable or a plug (not allowed in France), connect up directly.
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 a vital safety feature. The green-yellow earth wire must be longer than the phase wires. The installation must be equipped, upstream
of the appliance, with a bipolar cut-out device (contact opening at least 3 mm ; fuse, breaker switch.) If the ducts are made of insulating material,
the electrical contacts must be protected by a 30 mA earth-leakage breaker conforming to the applicable standards. Adapt the connection to the power
supply (see diagrams and table).
Before removing the cover, switch off the power.
Thermal circuit breaker:
All our products are equipped with a thermal circuit breaker with manual resetting which shuts off the power to the water heater if it becomes overhea-
ted.
If the circuit breaker keeps tripping,
a) switch off the power before taking any further action, b) remove the caver, c) check the electrical connections, d) reset the thermal circuit breaker.
If the circuit breaker continues to trip, replace the thermostat. Never by-pass the safety device or the thermostat. Connect the power supply only
via the terminal.
For electronic products with a power higher or equal to 1800 W, it is possible to switch in Tri Phase 400W using the facilitri Kit 400V.
COMMISSIONING / USE
Never switch the water heater on without it being filled with water.
Before switching on, open the hot water taps, bleed the pipes until no air is present and fill the appliance.
Check that the pipes and the door seal under the caver are not leaking. If there are any leaks tighten gently. Check that the water safety devices are
working and fill the appliance. Switch on the appliance. After 5 to 20 minutes according to the capacity of the appliance, water should start dripping
from the drain outlet. This is normal and results from the expansion of the water. Check that joints and seals are watertight. In the course of heating up,
shielded water heaters may make a boiling noise ; this is normal and does not indicate any fault with the appliance.
To avoid the development of bacteria (legionella...) ensure that a temperature of 60°C is reached every day. The thermostat is set at the factory at (65°C+-
5°C. or 78+-3°C according to model).
