● The steel plate tank is designed to resist a
pressure that is higher than the working
pressure.
Its corrosion protection is provided by a
layer of vitrified enamel and an impressed
current anode.
● The heating element consists of a ceramic
element that heats the water inside the
tank.
- The ceramic element protected by an ena-
mel-coated sheath, which makes it unne-
cessary to empty the heater when replacing
the element.
● The thermostat controls the water tempe-
rature.
It is preset in the factory to the "upper stop
gauge", about 65°C +/- 5.
● A temperature circuit breaker is provided
for safety if the water temperature should
rise abnormally.
● The tank is protected against corrosion by
a very low voltage impressed electrical cur-
rent.
- The electronic panel permanently provi-
des the necessary current for this protec-
tion, both in peak hours and in off-peak
hours.

Installation of the heater
IMPORTANT
● Put the water heater where it is protected from
frost.
● Position it as close as possible to the most fre-
quently used taps.
● If it is installed in an uninhabited room (store-
room, cellar, garage) the pipes should be insula-
ted. The continuous ambient temperature
around the water heater must not exceed 40°C.
● Make sure that the wall-bracket is strong
enough to carry the weight of the water heater
when full of water.
● Allow 500 mm of space in front of each elec-
trical equipment for periodic maintenance of the
heating element.
●
Install a retention tank under the water heater
if it is placed inside a false ceiling, in the attic, or
above inhabited rooms. An outlet connected to
a drainpipe is necessary.
● The applicable standards and national regula-
tions on fitting, plumbing and electrical connec-
tions must be implemented on installation.
Example
Installing a vertical wall-mounted water heater (VM)
Handles are built into both ends to facilitate handling.
Several attachment types are possible depending on the nature of the wall :
A) Thin walls (plasterboard partition).
ø 10 mm threaded rods passing through the wall connected by sections or plywood panels.
B) Thick hard walls (concrete, stone, brick)
Grout in ø 10 mm bolts or drill holes to fit ø 10 mm MOLY type inserts.
C) Vertical wall-mounted water heaters may be placed on a tripod when the partition can-
not support the weight of the heater. An additional upper stirrup attachment is compulsory.
Use the tripod recommended by the manufacturer.
Use the attachment template printed on the packaging box for both types of walls
and check the centre distance of the holes.
