IMPORTANT:
In the event of installation of battery appliances, it is imperative to install a safety valve specific to
each appliance.
Safety units for the whole of the range (as option) to be installed on each appliance.
These valves must be calibrated at 7 bar maximum and comply with NF.
NB:
Generally, with regard to combating the proliferation of Legionnaire’s Disease, it is
necessary to comply with the recommendations of the Conseil Supérieur d’Hygiène
Publique de France, and more particularly the conformity of materials and equipment
implemented in respect of the compatibilities defined on pages 59 & 61 of the risk
management guide linked to Legionella of November 2001
The quality of the water distribution pipes is very important.
Beware of connections between different metals; we advise you to comply with the
instructions of DTU 60-1.
Provide a dielectric insulating connection near to the appliance on each pipe connecting to
the water network.
Verify that the pressure of the distribution network does not exceed 5 bars.
Otherwise, install a pressure reducer upstream of the appliance and its safety
systems.
EN 12 Document ref.: 428016 03
To enable the expansion of the water in the water heater, the safety valve must be
fitted with a pipe which will allow this expansion to overflow into a funnel connected
to the drain. Under no circumstances must you reduce its diameter or close this pipe
with a plug or a stop valve. Plugging will invalidate the warranty of the appliance.
Fitting of a filter on the cold water inlet is strongly recommended in order to
eliminate foreign matter such as sand, gravel, sludge, etc.
It is imperative to install a T-square on the low pipe of the appliance enabling a direct
transition valve to be fitted in order to carr out shunts ad eliiate sludge
stagnating at the bottom of the tank.
Provide a degasser with air drain on the hot water outlet (evacuation of dissolved
gas).
Equip the water heater with a domestic circulating system for proper
homogenisation of the water volume
For the purposes of combating Legionella, it is imperative that any thermostatic
mixer is installed as close as possible to the supply points, in order to minimise the
water circuit to 40°, temperature for maximum proliferation of Legionella
There must be no cutout or regulation system between the tank and the safety valve
4. HYDRAULIC TESTS
Upon first filling with water, it is down to the installer to verify the seal of the upper flange
and the manhole, and to tighten the bolts if necessary.
After hydraulic connection of all pipes, and before carrying out the electrical cabling,
completely fill the appliance and pressurise it.
Check and rectify the watertightness of each connection.
After each intervention on the hydraulic installation, it is imperative to carry out a
hydraulic seal test
EN 13 Document ref.: 428016 03
5. ELECTRICAL CONNECTION
Before connecting the appliance, check that the power is off, that the appliance is full of
water and that it is watertight.
Recommendations for installation:
The electrical installation must comply with national regulations in force in the
country of installation. For France, see standards NF C 732OO and NFC 15100.
Install a general circuit breaker and calibrated protection upstream on the electrical
supply.
Use correctly sized ires refer to the aufacturers’ alues ad esure all
connections are fully tightened.
The components mentioned on the electrical diagrams are provided with the
electrical kits.
Each component and the tank must be connected to earth (via the sleeves situated
on the flange of the tank).
The resistances must be supplied using an electromagnetic switch (not provided).
Connect its electrical circuit and the loop pump using terminals C1 and C3 of the
terminal block.
Never block it manually.
Do not install manual override switches.
It must be sufficiently sized.

IMPORTANT
Every installation MUST comprise a correctly sized hydraulic safety device against:
Overpressure in the distribution network.
Overpressure due to temperature rises (expansion during heating).
Overpressure due to failure of a thermostat or a contact switch.
The sizing of a hydraulic safety device varies according to:
the capacity of the appliance,
the power of the appliance installed.
A hot water expansion vessel and a anti hammer can also be connected to protect the entire
installation. The implementation of these devices will take into account regulatory
recommendations and those of their manufacturers
In the event of installation of battery appliances, it is imperative to install a safety valve specific to
each appliance.
Safety units for the whole range (as option) to be installed on each appliance.
These valves must be calibrated at 7 bar maximum and comply with NF.

15. COMMISSIONING
15-1 CHECK THAT THE TANK IS FULL OF WATER
To do this:
Fill the water heater (by opening the water inlet valve and a hot water
supply tap to evacuate the air from the tank).
The water heater is full when the water flows normally at this tap.
NB The appliance must never be connected to the mains when it is empty;
the electrical components (if existing) may become damaged.
VERY IMPORTANT
15-2 CHECK:
That the connections are suitable for the specifications of the current
distributed and the heating components.
That all connection terminals are securely tightened.
That the element or the thermostat is not short circuited.
The free flow of the safety valve(s) and their correct sizing.
The good watertightness of the seals, the flange and any electrical
components.
15-3 CONNECTING TO THE MAINS
Connect to the mains and monitor the first rise in temperature in order to
check the thermostat cuts in properly.
15-4 WATERTIGHTNESS
After a few days of operation, check that all seals are watertight.
16. SHUTDOWN OF THE SYSTEM
NORMAL
(less than 3 months, no risk of frost)
Shut off the power to the water heater.
Close the cold water inlet.
PROLONGED
(over 3 months)
Shut off the power to the water heater.
Drain the appliance: Close the cold water shutdown tap
Open a tap on the hot water circuit

With regard to the water temperature:
The distribution temperature of 65 °C is the ideal temperature for most
needs. However, in the event of hard water the water temperature must be
below 60 °C to limit the scaling of the heating elements.
In the event of boiling in a water heater and emission of steam jets at the
supply taps, immediately switch off the power, open a hot water tap and
notify your installer.
To define an average water temperature via the thermostat, refer to the table
below. (The temperatures on the table are only guidelines and need to be
checked by the user. They cannot be considered as formal and remain
dependent on the thermostat).
With regard to the expansion of the water volume in the tank
Normal dripping of water occurs upon each heating by the safety unit. This
normal phenomenon is inevitable following expansion of the heated water.
:
REMINDER: It is essential to connect the system or the valve to a visible
permanent discharge.
Quality of the water
I order to esure a aiu life epectac of our ater heater and benefit
from the warranty, certain rules must be respected:
:
Hard water: provide an effective anti-scale device
Soft water: Have: - a TH between 12 and 30° F,
NB: Our warranty will not apply if, in the event of incident, these
instructions have been neglected or if the water quality does not allow
correct treatment within the framework of the legislation.
- a pH between 6.8 and 7.3
- resistance between 2200 and 4500 ohm/cm.
EN 32 Document ref.: 428016 03
18. MAINTENANCE AND CLEANING
SWITCH OFF THE ELECTRICAL SUPPLY BEFORE ANY WORK ON THE APPLIANCE
The frequency of interventions depends on the quality of the water stored and
the output. However, it is recommended to check the condition of the heating
elements and the inside of the tank twice a year. These water heaters have an
enamelled internal coating. This protection is completed with two or three
magnesium anodes accessible from the front. Check the anodes three months after
filling.
These anodes will wear according to the quality and consumption of water and
its temperature. The anodes must be checked regularly and replaced when their
diameter is below 10 mm.
The internal corrosion protection warranty shall only apply if the anodes have been
checked and changed at the appropriate times.
Nevertheless, for soft water and for regions where the water is very aggressive
or acidic, it is essential to have the water neutralised with an appropriate treatment.
Failure to observe this rule will invalidate the warranty (see Water Quality chapter).
Monthly operation
Check the correct operation of the safety valve (or safety unit) by manoeuvring
the lever that lifts the heating reset flap valve, to check that the water is
expanding normally. A slight drip may manifest during operation of the
appliance.
Carry out shunts via the quick drain valve to eliminate any sludge stagnating at the
bottom of the tank.
Half-yearly operation
Dismantle the heating elements (resistances and sheath) and clean them carefully
of any deposit.
Descaling
In regions where the water is rich in calcium, it is recommended to frequently
check the inside of the tank and remove the scale with a water jet.
If the tank is too scaled, carry out chemical descaling.
As this operation is tricky, you are strongly advised to use a specialised company.
Important note:
Before reassembling each element comprising a seal, change the seals.
EN 33 Document ref.: 428016 03
Annual operation (mandatory)
Dissemble the flange and the heating elements (resistances and sheath)
Check the inside of the tank; descale if necessary
Change the seal
Dismantle the heating elements (resistances and sheath) and clean them
carefully of any deposit.
As this operation is tricky, you are strongly advised to use a specialised company.
Our warranty will not apply if, in the event of incident, this operation has been
neglected.
19. TROUBLESHOOTING
This appliance has been designed to give you full satisfaction. However, here are a
few examples of possible malfunctions and the related solutions.
SWITCH OFF THE POWER BEFORE ANY INTERVENTION ON THE
No hot water at all
a) The appliance has not yet worked:
First check that the safety thermostat is not activated. Press the black button
on the outside of the unit to reset it. Incident often caused by transport.
Check, using a voltmeter, that the current is reaching:
1 - the thermostat, otherwise check the circuit breaker, the fuses, the EDF
eter or a other reote cotrol prograed to “TOP.
2 - the switch, otherwise check the thermostat and its adjustment, which
may be too low.
3 - the resistances, otherwise check that the switch is not abnormally stuck
in the open position.
4 - check:
the connection of each resistance
that it corresponds to the type of current
the cabling diagram of the instructions.
5 - Lastly, replace the resistances
b) The appliance has worked before:
If the safety device is not at issue, check the power supply with a voltmeter, in the
order of points 1 to 5 above.
APPLIANCE
EN 34 Document ref.: 428016 03
Insufficient hot water
Check successively:
the adjustment of the thermostat, and modify it if it is not in the stop position,
the correct tightening of the connections,
the power of the resistances on the three phases and the type of current used,
use an ohmmeter to check for faulty elements whose values are too far from the
averages read,
change the resistances in question.
Evaporation or water much too hot
Check
:
the condition of the thermostat and its adjustment temperature,
that the switch is not blocked and that its cutout power is adapted to the power
consumed,
that no remote control is shunting the thermostat.
descaling of the thermowell of the thermostat
Losses of earth perceived on the taps and pipes
:
Check
that the appliance and its components are properly connected to earth and that
this is effective,
the tightening of the connections,
the condition of the components (resistances, thermostat) to detect any
accidental earthing.
Water leaks
A dripping flow in the discharge of the safety valve is normal; it is caused by the
expansion of the water in the heating periods.
On an ongoing basis
Check the pressure of the cold water; if this is greater than 4 bars, install a
pressure reducer upstream of the safety valve.
Check the hot water and cold water connections and the flange seals. Tighten
them or change them.
Lastly, implicate the tank and contact the supplier.
