Fastening
Horizontal 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.
Horizontal water heaters may be fastened to a wall or the ceiling. In
either case, the connections may be placed to the left or right-hand
side of the heater.
Electrical connections
Horizontal 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.
Grounding the metal parts (with the special terminal on the unit) is
compulsory. The section of the line, the omnipole breaking device
and the protection system (fuses or circuit-breakers) shall be selec-
ted in keeping with applicable standards, depending upon the input
intensity, 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 hea-
ted 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.
