HYDRAULIC CONNECTIONS WARNINGS
It is mandatory to screw on to the appliance's water intake pipe a suitable device against
overpressure (not supplied). In countries which acknowledge EN 1487, the appliance's water intake
pipe must be equipped with a safety device compliant with previously mentioned standard.
It must be new, with 3/4" dimensions and calibrated to a maximum pressure of 0.7 MPa, including
at least a cock, check valve, safety valve and hydraulic load cut-out.
This safety device must not be tampered with and must be made to operate frequently in order to
check that it is not blocked and to remove any limescale.
The water may drip from the discharge pipe of the pressure-relief device and the pipe must be
left open to the atmosphere. The discharge pipe connected to the pressure-relief device is to be
installed in a continuously downward direction and in a frost-free environment.
A pressure reducer (not supplied) is required when the inlet water pressure is greater than 0.7 MPa
(7 bar), which must be attached to the water mains.
The minimum inlet water pressure for the correct operation of the appliance is 0.15 MPa (1.5 bar).
Connect a rubber pipe to the condensate drain, taking care not to force too much so as not to break
the drain pipe and refer to par. "6.6.1".
Use only connecting pipes (not supplied), rigid and resistant to electrolysis both at the inlet of cold
water and at the outlet of hot water from the device.
For models that incorporate a heat exchanger (solar coil), the circuit must not exceed 1.0 MPa (10
bar) and its temperature must not exceed 80°C.
Refer to description and illustrations in the "Hydraulic connections" paragraph 6.6 and "Integration
with solar thermal system" paragraph 6.7.
ELECTRICAL CONNECTIONS WARNINGS
The appliance shall be installed in accordance with national wiring regulations.
The electrical installation must include an all-pole disconnection with a separation of the contacts
on all poles capable of guaranteeing complete disconnection in the overvoltage category III
upstream of the appliance, complying with local installation rules in force .
The device must be protected by an adequate differential switch (max 30 mA). The type of
differential switch should be selected by assessing the type of electrical devices used by the
system as a whole.
Earth connection is mandatory. The manufacturer of the appliance shall not be held liable for any
damage caused by failure to earth the system or due to anomalies in the electric power supply.
It is strictly forbidden to connect the appliance at the AC mains through extensions or by a power strip.
Before taking off the cover, make sure that the power is turned off to prevent injury or electric shock.
Refer to description and illustrations, respectively, in the "Electrical connections" paragraph 6.8 and
"Wiring diagram" paragraph 6.9.
