2.5 – Electrical supply
The electrical connections must be done by
Qualified service engineering
. Before
beginning this operation, cut off the electrical supply.
1.
Check that the voltage supply is 240/50Hz single-phase
2.
Carry out the electrical connections accordino to the installation wiring diagram
3.
When connecting, censure that the earth wire is longer than the live wires, so that i
twill be the last wire to break if the supply cable is stretched, thus ensuring a good
earth continuità.
)
The electrical safety of the unit attained only when the unit itself is correctly
connected and efficiently grounded according to the exhisting safety standards.
4.
The unit should be connected to the electric supply line by means of an omnipolar
switch with a minimum contact opening of 3 mm. An omnipolar switch ia a “Double
pole isolating switch”, i.e. a switch capable of disconnecting both on phase and
neutral. This means that when the switch is opened, both contacts are disconnected.
2.6 - Water
The cooler must be supplied with fresh,
mains water to maintain hygienic and
efficient operation. It is connected to the
underside of the cooler using a 1/2” bsp
connection. The water pressure must a
minimum of 1 bar and a maximum of 7 bar
with a total flow rate of 500l/hr.
It is recommended that a ‘double check’
valve is fitted. All water installations
should conform to local regulations.
A flexible connection pipe is provided.
It is recommended that this used to
prevent stress on the water solenoid valve
fitting
