Climate Control Simplex
Operation
Factory calibrated snap-acting DPST pressure electric
switches provide automatic cut-in and cut-out. Overpressure
protection is provided by an ASME safety relief valve. Receiver
tanks have a condensate drain valve with an extension for
easy access. All mounting bases are slotted for V-belt tension
adjustment to aid in maintaining proper compressor and
motor alignment.
All units are run through the factory break-in and are tested
for air delivery, leakage and power consumption.
Units are shipped with a proper fi ll of compressor oil in the
crankcase and are furnished with an intake fi lter/silencer with
a replaceable cartridge. This fi lter/silencer combination is
designed to remove contaminates in the inlet air and provide
quieter operation.
LUBRICATION
Check lubricating oil level at gauge. Refi ll if necessary. See
Figure 1.
Change oil according to maintenance schedule. Before
draining oil, remove oil supply cap and loosen oil drain cap to
release trapped air. Use Mobil Rarus 427
®
or Mobil DTE heavy
oils.
NOTE:
All pump models operate turning clockwise opposite
the motor shaft / pump fl ywheel / belt guard side of the unit.
Improper rotation will cause oil to spray out of the breather
vent opening.
Dispose of oil in accordance
with state or local codes.
