Electric Motor/ Petrol Engine:
W32 Series of compressors can be driven by electric motor or petrol engine. They
are belt-driven. They have an hourmeter which shows the working hours of the unit
on the electric motor on W32 Mariner Electric models and on the control panel on
W32 Canopy models. There is no hourmeter on the petrol engine driven units.
Note
SEE THE INSTRUCTION MANUAL FOR THE ELECTRIC MOTORS OR PETROL
ENGINES SUPPLIED ALONG WITH THE COMPRESSOR.
Pressure Switch (Available on W32 Canopy and Automatic Start/Stop Controlled Mariner
Models):
Pressure Switch enables the compressor stop and restart automatically between the adjusted upper and
lower pressure limits. SEE THE ADJUSTMENTS PART FOR THE PRESSURE SWITCH
ADJUSTMENTS.
Automatic Drain Valve: (Available on W32 Canopy and Automatic Drain Controlled Mariner Models):
Springs inside the drain valves are on the top in high pressure drain valves while they are at the
bottom in low pressure drain valves. Thus, surface where low pressure acts on is larger than the
surface where the high pressure effectively acts on the piston. Therefore force on the top is larger
and causes the piston to sit and seal the high pressure vent port. Automatic drain valves take their
control air from a solenoid. It takes compressed air from the inlet to the 2nd stage valve and sends it
onto 2 drain valves forcing them to close. When the solenoid is deenergised, it does not let the air goes on the top
of the drain valve pistons, allows the high pressure acting from the bottom of the pistons, to open and perform
drain operation.

Inter Coolers and After Cooler:
These are the cooling tubes cooling the warm air compressed in stages which are located interstages and at the
discharge of the final stage of the compressor.
INTERCOOLERS AND AFTER COOLER ARE NOT NECESSARILY REPLACED UNLESS A
WEARING, CRACKING OR BREAKING OCCURS.
Water Separators:
Condensate in the compressed air occured in stages during the compression is removed from air by water
seperators.
Note
REPLACE WATER SEPARATOR FILTERS PERIODICALLY AS MENTIONED IN THE
MAINTENANCE TABLE.
