MACHINES WITH WATERCOOLED CONDENSER
To make the machine run, a watercooled machine must be connected to running water supply,
or to a cooling tower.
Water must have a pressure of 0.1 MPa and 0.5 MPa (1-5 bar) at least, and a delivery at least
equal to the estimated hourly consumption.
Connect inlet pipe marked by plate "Water Inlet" to water supply installing a shut-off valve, and
outlet pipe marked by plate "Water Outlet" to a drain pipe, installing a shut-off valve.
2.4.1 Water valve adjustment
IMPORTANT
If water valve needs be reset, this operation will have to be carried out by skilled personnel,
only.
Valve adjustment must be carried out in such a way that no water flows when machine is off and
lukewarm water flows when machine is on.
NOTE:
Water consumption increases if temperature of entering water is above 20°C.
ATTENTION:
Do not leave the machine in a room with temperature below 0°C
without first draining water from the condenser.
2.5 ELECTRICAL CONNECTIONS
The power supply system must comply with the national regulations in force in the place of
installation and provided with an efficient ground connection.
The manufacturer is not responsible for any malfunction or for injury to persons and/or damage
to property resulting from connection to a non-compliant electrical system.
The appliance must be installed according to the current regulations for electrical installation,
by competent and qualified technical personnel meeting the technical and professional require
-
ments provided for by the legislation in force in the country of installation.
Before connecting the machine to the mains, check that the mains characteristics meet those of
the machine specified in the identification plate applied to the machine itself.
Check that the power supply network is provided with a disconnection device, in compliance
with the installation rules, ensuring complete disconnection from the mains for each pole (dif-
ferential circuit breaker), in the conditions of overvoltage category III. The opening distance of
contacts must be at least 3 mm.
Check that the trip level of the differential circuit breaker is ≤ 30mA.
The machine is supplied with power cable; in case of three-phase machine with neutral, the
blue conductor of the power supply cable must be connected to the system neutral.
WARNINGS
The machine is fitted with an electric supply cable including a yellow/green cable, which
MUST be connected to an appropriate grounding of the electric system.
2.5.1 Equipotential connection
Connection to external equipotential terminal is indicated by symbol .
It is present on the side or on the back of the machine, not to be connected to the protection
ground.
The conductor to be used has a cross-section at least equivalent to the one of the connected
conductor with greatest cross-section.
2.5.2 Replacing the power cable
If the machine power cable is damaged, replace it immediately with a cable with the same
features. Replacement must be carried out by qualified personnel only.
