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
Remote controls
Check that the remote controls (ON-OFF etc) are connected and,
if necessary, enabled with the respective parameters as indicated
in the “electrical connections” section.
Check that probes and optional components are connected and
enabled with the respective parameters (“electrical connections”
section and following pages).
