the sewer is required.
LOCATION
INSTALLATION OF A VERTICAL WATER HEATER (Figure 2)
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)
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 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)
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

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 6/7 D and E)
The water heater can be connected and powered only by a single-phase 220-240 V
AC or a three-phase 380-400 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
overheated. If the safety device is tripped, cut the power before any
operation and have the circuit breaker reset by a professional.
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 output greater than or equal to 1800 W,
it is possible to switch to three-phase 400V using the Facilitri 400V kit. The
modification must be made by a professional.
For products which are equipped with a mechanical thermostat and compatible
with single-phase and three-phase connections, the wiring must be modified by
a professional and only using the equipment supplied by the manufacturer.
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).
If steam or boiling water emerges continuously from the drain plug or drain
tap, switch off the electricity and call a professional.
When first powered, a smoke and an odor may be released from the heating
element. This is normal and it disappears after a few minutes.
MAINTENANCE
User maintenance:
Operates once a month the discharge of water security to prevent scaling and
verify that it is not blocked. If this is not done, damage may be caused and
the guarantee invalidated.
Maintenance by a qualified person:
- Remove the scale sludge. Do not scrape or chip at lime scale deposited on the casing because this may damage the lining
- Change the magnesium anode every 2 years or when its diameter is less than 10 mm. Changing the shielded heating element or the anode requires the water heater to be drained and the seal changed.
Drain:
Turn off the power and the supply of cold water, open the hot water faucets
and manipulate the safety valve before performing these operations. Refit the
heating element and tighten the screws gently (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.
Replaceable parts:
The thermostat, seals, heating element, boiler shell, the indicator light, the
magnesium anode, the connection cable. The guarantee requires genuine
manufacturer’s parts to be used.
Do not dispose your water heater in the garbage, but hand it to a place
assigned for this purpose (collection point) where it can be recycled.
