The boiler is equipped with a power
cable, boiler installation requires elec-
tric al connection to the mains power
supply. This connection must be made
up to standard, as required the regula-
tions in force.
Remember that a bipolar switch must
be installed on the boiler power line
with over 3 mm between contacts, easy
to access, making maintenance quick
and safe.
The power cable must be replaced
by technical personnel authorised by
UNICAL AG S.p.A., using original spare
parts only. Failure to comply with the
above can jeopardise the safety of the
appliance.
If necessary the shield of the sensor
cable, can be connected to the termi-
nal. (Ground connections - modulation
board).
