Product Manual

Polar Air Rotary Screw Compressors
23
Use only Polar Air oil, model
no.Oil003. For food manufacturing applications,
use model no. Oil001. Use of any other product
causes product damage and voids the warranty.
Refer to warranty statement for oil requirements.
Failure to perform regular oil
changes may cause equipment damage and will
void warranty. Oil must be changed annually
regardless of hours used.
Belts
To avoid serious personal
injury, be sure to relieve all
system pressure then lock out
power and tag compressor to
prevent unexpected movement
of the unit.
Inspect belt tension after first 30 hours of
operation then at every 1,000 hours.
1. Check belt tension on each individual belt
in the center of each pulley, and should
have ¼”deflection up and ¼” deflection
down, for ½” total.
2. Always replace all belts with the same
brand, at the same time. Make sure belts
are unimatched. Do not replace belts
independently.
3. Do not splash lubricating oil on belts or
pulleys when adjusting or replacing belts.
System Pressure
System pressure is factory set but can be regulated
depending on operating conditions. Refer to
computer control specifications for setting
adjustments or PLC operating manual.
Safety Valve
TO AVOID SERIOUS
INJURY OR DEATH, NEVER
ATTEMPT TO REGULATE
OR TAMPER WITH SAFETY
VALVE. VALVE IS SEALED
AND CERTIFIED BY ASME CODE AND IS
DESIGNED TO RELIEVE SYSTEM
PRESSURE WHEN NECESSARY.
Air/Oil Separator Filter
Air/Oil Separator tank is a
pressurized component. To
avoid serious injury, be
sure system pressure is
relieved before removing
filter. Be aware oil
temperature may be very hot. Use caution
when changing filter.
1. Relieve all air pressure from air/oil
separator tank, then wait approximately
5-10 minutes before replacing filter.
2. Replace air/oil separator filter. Do not
attempt to clean.
OPTIONAL: Cabinet Intake Filter(s)
Current rotary screw compressors can now be
ordered with air-intake filters which reduce the
amount of airborne debris being pulled into the
unit, thus reducing the frequency of maintenance
and cleaning of the interior of the cabinet.
These filters are easily changed or installed on
current models; Number of filters (1 to 3) varies
with model. Typical filter installation is shown
below.
Remove 4 Phillips-head
screws on small panel
to access or install
Remove 2
Phillips-
head
screws on
large panel
to access
or install
filter.
Use only OEM filters. Other filters may create air
restrictions, causing overheating issues.
