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 said standard.
It must be new, with 3/4" dimensions and calibrated to a maximum pressure of 0.7 MPa (7 bar), 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 that this 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. "6.5.1 Condensate drain connection" on page 94.
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 "6.5 Hydraulic connections" on page 93
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 "6.6 Electrical connections" on page 94 and "6.7 Wiring
diagram" on page 97.
