Refer to National Electric Code or applicable local codes to
determine proper fusing or circuit breaker rating. If using fuses,
time–delay or slow–blow fuses are recommended.
COMPRESSOR LUBRICATION
A. Oil fill plug
B. Low oil level switch
C. Oil drain plug
CAUTION
Do not operate without lubricant or with inadequate lubricant.
Ingersoll–Rand is not responsible for compressor failure caused by
inadequate lubrication.
We recommend ALL SEASON SELECT synthetic compressor
lubricant.
You may use a petroleum–based lubricant that is premium quality,
does not contain detergents, contains only anti–rust, anti–oxidation,
and anti–foam agents as additives, has a flashpoint of 440
_
F (227

or higher, and has an auto–ignition point of 650
_
F (343
_
C) or higher.
See the petroleum lubricant viscosity table below. The table is
intended as a general guide only. Heavy–duty operating conditions
require heavier oil viscosity. Refer specific operating conditions to your
dealer for recommendations.

NOTE
If you use a petroleum–based compressor lubricant at start–up and
decide to convert to ALL SEASON SELECT lubricant later, the
compressor valves must be thoroughly decarbonized and the
crankcase must be flushed before conversion.
Filling Procedures:
1. For enclosed compressors, remove the front panel.
2. Unscrew and remove the oil fill plug.
CAUTION
Do not remove the oil fill plug while the compressor is running.
3. Slowly fill the crankcase with lubricant until the lubricant reaches the
top thread of the oil fill opening and the top of the sight glass.

4. Replace the oil fill plug HAND TIGHT ONLY.
LOW OIL LEVEL SWITCH
A float activated low oil level switch may be installed to protect your
unit against damage due to insufficient compressor level oil. Low oil
level in the compressor crankcase causes the switch contacts to close,
thus energizing the shunt coil in the combination pressure switch. This
in turn shuts the pressure switch off. Once proper oil level has been
restored the pressure switch (control panel) lever needs to be turned
to Auto to start the unit.
Proper protection against low oil level depends on proper
adjustment of the low oil level switch. During the initial run, stop the unit
and drain one quart (0.946L) of oil from the compressor crankcase into
a suitable clean container. Listen for the switch to click or check the
switch with a continuity tester.
NOTE
On enclosed compressors, the front panel must be removed to
access the low oil level switch.
