Maintenance and periodic controls
WARNING: All operations described in this chapter MUST ALWAYS BE CARRIED OUT BY QUALIFIED
PERSONNEL. Before carrying out any operation on the unit or accessing internal parts, make sure that
power supply is disconnected. The heads and the delivery pipe of the compressor are usually at quite high
temperature. Pay special care while working near the batteries. Aluminium tabs are very sharp and can
cause serious injury. After maintenance operations, close the panels by securing them with fixing screws.
It is forbidden to refill cooling circuits with a refrigerant different from the one indicated in the nameplate.
The use of a different refrigerant can seriously damage the compressor.
It is forbidden to use oils different from those specified in this manual. The use of a different oil can
seriously damage the compressor
It is good practice to carry out periodic controls to check the correct operation of the unit:

Water circuit filling.
x
Presence of bubbles in water circuit.
x
Check the correct operation of control and safety devices.
x
Check that no oil leaks from the compressor occur.
x
Check that no water leaks in the hydraulic circuit occur.
x
Check that the flow switch operates correctly.
x
Check that casing resistances are powered and operational.
x
Clean metallic filters of hydraulic circuit.
x
Clean the battery with tabs using compressed air or jet of water.
x
Check that the electric terminals both inside the electric panel and in the terminal boxes of the
compressor are properly fixed.
x
Tightening of hydraulic connections.
x
Check fan fastening and balancing.
x
Correct electric voltage.
x
Correct power consumption.
x
Check of refrigerant charge.
x
Check of working pressure, overheating and subcooling.
x
Circulation pump efficiency.
x
Check of expansion reservoir.
x
If the unit is not used for a long period, drain water from pipes and from heat exchanger. This
operation is essential if, during the period of inactivity, ambient temperatures lower than the freez-
ing point of the fluid used are expected.
