RECOMMENDATIONS
· Fit burn out suction line drier /filter (temporary assemblies available)
· Use of acid neutralizing products is not recommended.
· Replace liquid line drier.
· Ensure oil failure switch operates-Remove compressor motor fuses and turn on control- to check DO not rely on SUCTION ACCUMULATOR to clean up liquid flood back – SUCTION SUPERHEAT must be calculated.
( most compressor failures are caused by liquid
refrigerant in the compressor.)
· System dryness and acid levels are most important particularly with polyester oils - change liquid line drier after approx 12 Hr COMPRESSOR running
check sight glass indicators and oil samples until satisfactory
(Oil analyzing available.)
· If the compressor failed and corrective measures have not been made the next compressor WILL fail – it is cheaper to fix the problem than keep replacing compressors.
INFORMATION
PLEASE READ BEFORE INSTALLING COMPRESSOR.
## Inspect compressor for damage and
missing components – if damaged
report it on the delivery docket and
advise Ganley Refrigeration.
## Check motor insulation and winding resistances’
## Check electrical connections are correct
for the application
SEE SKETCH BELOW
## Check correct oil is charged into
compressor for the application.
All compressors are supplied with Polyolester
as standard unless requested otherwise
SEE LABEL ON COMPRESSOR
## Check if oil cooler connection or head
cooling fan is required.
Some compressors must have the oil
cooler connected to enable lubrication of
the running gear
AFTER INSTALLING
## Check motor electrical connections ,contactors,
and controls
Note. DWM and Copemetic have different
Thermister control relay units and part
winding configuration.
CONTACT GANLEY REFRIGERATION
## Check oil pressure(pump models) min
200kpa differential ( pump-suction)
## Check motor current draw
SEE NAME PLATE AMPS
## Check oil level-1/4 to 1/2 sight glass
## Check suction superheat(suction pressure
at compressor + 10Kpa converted to Temperature
subtract away suction line temperature at
the compressor inlet) use insulated probe of
known accuracy-
NOT LESS THAN 12oC
