OPERATIONAL SEQUENCE
Refrigerant Charge
Liquid refrigerant should be charged into the condenser before compressor starting to
ensure that refrigerant is present at compressor start-up.
Crankcase Heater
The mains supply to the crankcase (oil) heater should be switched on at least 8 hours
prior to compressor starting to avoid refrigerant migration.
CAUTION
A separately fused, locally isolated, permanent single phase and neutral supply
MUST BE FITTED
for the compressor sump heater, evaporator trace heating and
control circuits, FAILURE to do so could INVALIDATE WARRANTY
.
Pre-Start-Up Check
Before compressor start-up, make sure that an oil level is showing in the compressor
sight glass, and that all refrigerant ball valves are opened.
Checks at Compressor
Start-up
As soon as the compressor starts, make sure that the solenoid valve for liquid injection
opens, and that the suction and liquid/discharge pressure gauges are showing low and
high pressures respectively.
If there is no liquid present or no differential pressure occurs, isolate immediately.
CAUTION
Check phase rotation by connecting pressure gauges to the suction and
discharge ports.
Liquid Injection - Never shut down the liquid injection circuit whilst the compressor
is still running, at any loading condition as this may permanently damage
the compressor.
