Compressor casing resistances
Connect the compressor oil heating resistances at least 8 hours
before the compressor is to be started:
at the first unit start-up
after each prolonged period of inactivity
1 Power the heaters: isolator switch on 1 / ON.
2 Check the power consumption of the resistances to make sure
that they are functioning.
3 Start-up the compressor only if the crank-case temperature on
the lower side is be higher than the outside temperature by
at least 10°C .
4 Do not start the compressor with the crankcase oil below
operating temperature.
Voltage
Check that the air and water temperatures are within in the
operating limits.
Start-up the unit.
While the unit is operative, i.e. in stable conditions nearing
operating ones, check:
Power supply voltage
Total absorption of the unit
Absorption of the single electric loads
