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.

Reading the objective operating conditions is useful for checking
the unit over time.
With unit of full load, namely in stable conditions and close to
those of work, take the following data:
•
Voltage and general absorptions with unit at full load
•
Absorption of varied electrical loads (compressors, fans,
pumps etc)
•
Temperatures and capacities of different liquid (water, air) in
the inlet and outlet of the unit.
•
Temperature and pressures on the characteristic points of the
refrigerating circuit (compressor discharge, liquid, intake).
The readings should be stored and made available during
maintenance .
