* = For Models 2000 and 2000P, use Ingersoll-Rand
XL-740HT Compressor Oil in temperatures above 100°F
(37.7°0).
If you use a petroleum-based compressor lubricant at start-up and
decide to convert to All Season T30 Select later on, the pump must
be decarbonized and flushed before conversion. Contact
Ingersoll-Rand for more information.
FILLING PROCEDURES:
1. Unscrew and remove the oil fill plug.
2. Fill the crankcase with lubricant.
3. Replace the oil fill plug HAND TIGHT ONLY.
/_ CAUTION Do not remove the oil fill plug while the compressor
is running,
Refer to the following table for crankcase capacity.
Model Crankcase Capacity
2340 28 oz.(827 ml.)
2475 41 oz.(1212 ml.)
2545 73 oz.(2158 ml.)
7100 80 oz.(2365 ml.)
15T, 2000,2000P 144 oz.(4258 ml.)
Use one of the following methods illustrated to determine when the
crankcase is full,
A
E F
A = FULL level at bottom thread of oil fill opening on units without
sight glass or dipstick.
B = ADD level below bottom thread of oil fill opening on units
without sight glass or dipstick.
C = FULL level on units with sight glass.
D = ADD level on units with sight glass.
E = ADD level on units with dipstick.
F = FULL level on units with dipstick.
LOW OIL LEVEL SWITCH
A float activated low oil level switch may be installed to protect your
unit against damage due to insufficient compressor oil level. Low oil
level in the compressor crankcase causes the switch contacts to
open, thus shutting the unit down until the proper oil level has been
restored.
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 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.
The float sometimes gets cocked or stuck during shipping. If the
float is cocked or stuck, open the disconnect switch, drain the
remaining oil, remove the crankcase cover and then free the float.
Reassemble and then reuse the same oil.
NOTE
If the float is cocked in the low position, the unit
cannot start.
INTERMITTENT DUTY FORMULA
Units operating above 200 PSIG are to be operated according to the
"Intermittent Duty Formula."
INTERMITTENT DUTY FORMULA
Pump-up time should not ordinarily exceed thirty (30)
minutes or be less than ten (10) minutes. Shutdown
periods between cycles of operation should be at least
equal to the pump-up time. Note: When the compressor
is regulated by constant speed control, the shutdown
period is the time the compressor is operating
unloaded.
A pump-up time limit with the following cool-down period is
recommended to protect the valves and heads against stabilized
high operating temperatures, which could rapidly build up carbon in
these areas.
All inquiries for high-pressure compressor application where the
"use" cycle differs from the "Intermittent Duty Formula" should be
referred to Ingersoll-Rand.
START-UP (ELECTRIC MOTOR DRIVEN MODELS) __
