General warnings

HYDRAULIC CONNECTION

• A new safety unit, set to 0.8 MPa (8 bar) (not provided with the water heater) with a
minimum dimension of 1 / 2 '', and which complies with the standard EN 1487, must be
connected directly to the water heater's cold water inlet. It must be placed in a location
not at risk of frost (4 °C - 5 °C minimum).
• A pressure reducer (not supplied) is required if the supply pressure is greater than
0.5 MPa (5 bar). It must be installed on the cold water inlet, downstream of the meter.
• Your pipes must be rigid (copper) or fl exible (stainless steel woven hoses) and be able
to withstand 100 °C and 1 MPa (10 bar). Otherwise, a temperature limiter must be used.
• Connect the safety unit to a discharge pipe, kept uncovered, in an environment not
at risk from frost (min. 4 °C to 5 °C), continuously sloping downwards to drain off the
heat-expanded water or to allow for drainage of the water heater.
• The drainage device for the safety unit must be activated periodically (at least once
a month). This operation checks that the device is not blocked, and ensures any scale
deposits are removed.
• To drain the appliance, switch off the power and shut off the cold water supply, then
turn on a hot water tap and drain using the safety unit lever.
• Check that the water heater is fi lled correctly before it is powered on; when a HOT
WATER tap is turned on, COLD WATER should fl ow out.
• A small amount of smoke may be emitted when heating starts; this is completely
normal.

ELECTRICAL CONNECTION

Make sure to turn off the power before removing the cover to prevent any risk of injury
or electric shock.
The electrical installation must include an all-pole cut-out device (fuse holder, circuit
breaker with a minimum contact opening gap of 3 mm, 30 mA differential circuit
breaker) upstream of the water heater.
If the power cable is damaged, it must be replaced with a cable with the same
characteristics or a special pack available from the manufacturer or the after-sales service.
Grounding is mandatory. A special terminal marked is provided for this purpose.
Connecting the resistors directly to the network is prohibited.
This appliance is not designed to be installed at an altitude exceeding 3000 m.
The manual for this appliance is available from customer services (details at the back
of the manual).
