Fastening

Vertical wall-mounted water heaters are fastened with 4 bolts, dia.

10, sealed into the wall.
A drilling template is supplied with the unit to make it easier to mark

the drilling holes without any need to take measurements.
Two clamps fitted with notches (supplied with the unit) allow easy

fastening. The heater is packed upside down and placed on a poly-

styrene packing piece. In this way, the various parts are kept acces-

sible and it is easier to fit the clamps.

(*) Note: 50 L and 75 L heaters are fastened with only two bolts. The lower
clamp is replaced by a stop.

Stand:  75, 100, 150 and 200 L Standard vertical wall-mounted
water heaters may be placed on the floor on a stand designed for
standard vertical models which is available as an option. We recom-
mend that you fasten the upper clamp to the wall.

Electrical connections

Vertical wall-mounted water heaters are designed for a single-

phase 230 VAC power supply. The coupling of multiple voltage hea-

ters is user-modifiable, and may also be set for three-phase 230 V

or 400 V power supplies.

The metal parts must be grounded (with the special terminal on the

unit). The section of the line, the omnipole breaking device and the

protection system (fuses or circuit-breakers) shall be selected in

keeping with applicable standards, depending upon the input inten-

sity, voltage and power.

Note: The heaters must necessarily be connected to a fixed piping system. In prin-
ciple, power will be supplied to the heater at night, manually or automatically with the
help of a clock supplied by the electricity company. In this way, the water is heated
when the reduced off-peak rate is charged for electricity. The unit may be fitted with a
switch for supplying power in the daytime, when the full rate is charged.

Hydraulic connections

The connections are marked with blue (cold water) and red (hot
water) discs. Fitting a stop valve on the cold water supply pipe is
compulsory.

Safety rules require that a lead-sealed safety valve calibrated to 7
bar must necessarily be fitted on the cold water supply pipe (for the
guarantee to operate). We recommend the use of diaphragm type
hydraulic safety units bearing the NF mark. 

A pressure reducing

valve must be fitted if the supply pressure is greater than 5.5 bar.

Note : The composite material connecting piece (supplied in a bag) is to be
fitted on the hot water outlet of the heater. It is used to prevent the formation
of a galvanic couple, which can lead to the corrosion of the connection
threads when the heater is connected directly to copper or brass.
