WATER CONNECTIONS
A new safety device which conforms to current standards (in Europe EN 1487), pres-
sure 7 bar - 0,7 MPa - and size 3/4" (1/2" for 500 L) in diameter must be fitted. The
safety valve must be protected from frost.
Connect the safety device to an unpressurised outlet pipe in a frost free environ-
ment, with a continuous slope for the evacuation of the water during heating up or
draining the water heater.
A discharge pipe connected to the safety unit must be installed in a frost-free aera,
on a continuous downward slope.
Operates once a month the discharge of water security to prevent scaling and verify
that it is not blocked.
A pressure reducer (not supplied) is required when the water supply pressure ex-
ceeds 5 bar - 0,5 MPa.
Connect the safety device to an unpressurised outlet pipe in a frost free environ-
ment, with a continuous slope for the evacuation of the water during heating up or
draining the water heater.
DRAIN : Turn off the power and the supply of cold water, open the hot water faucets
and manipulate the safety valve before performing these operations.
ELECTRICAL CONNECTIONS
Before removing the cover, switch off the power.
The installation must be equipped, upstream of the appliance, with a bipolar cut-out
device ( fuse, breaker switch.) (30 mA earth-leakage breaker)
If the power cable is damaged, it must be replaced by the manufacturer, the after-
sales service or similarly qualified persons in order to avoid any danger.
