Compressor Lubrication, Filling Procedures

connected to the same circuit, the total electrica! load must be considered in selecting the proper wire size DO NOT USE UNDERSIZE WIRE

FUSES., Refer to the National Electric Code to determine the proper fuse or circuit breaker rating required. When selecting fuses, remember the momentary starting current of an electric motor is greater than its full load current Time-delay or "slow-blow" fuses are recommended.

COMPRESSOR LUBRICATION

CAUTION Do not operate without lubricant or with inadequate lubricant. Ingersoll-Rand fs not responsible for

compressor failure caused by inadequate lubrication

SYNTHETIC LUBRICANT. We recommend thgersolI-Rand synthetic compressor lubricant from start-up See the WARRANTY section for extended warranty information

ALTERNATE LUBRfOANTS. 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 fieshpoint of 440°F (227°C) or higher, and has an

auto-ignition polnt 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 viscosities,, Refer specific operating conditions to _our dealer for recommendations

you use a petroleum-based compressor lubricant at start-upand

decide to convert to Ingersoll-Rand synthetic compressor lubricant

later on, the compressor valves must be thoroughly decarbonized

and the crankcase must be flushed before conversion

FILLING PROCEDURES:

t,, Unscrew and remove the ell fill plug (A)

2.Slowly flit the crankcase with lubricant until the lubricant reaches the top thread of the sit filI opening and the top of the sight glass Crankcase capacity for the SS3 Is one-half (0 5) Iiter Crankcase capacity for the SS5 is one (1) liter.,

3.Replace the oil fill plug HAND TIGHT ONLY

Filling Procedures

INITIAL START-UP

Follow this procedure before putting the unit into service for the first time:

t.Set the pressure swffch lever to "OFF"..

Pressure Switch Lever

OFF"ON/AUTO

2.Open the service valve fully to prevent air pressure from building in the tank. (A=Open, B=Closed)

Service Valve

3.Move the pressure switch lever to "ON/AUTO _ The unit will start

4.Run the unit for 30 minutes Ensure the service vaive is fully open and there is no tank pressure build up

CAUTION Unusual noise or vibration indicates a problem Do not continue to operate until you identify and

correct the source of the problem., IF EMERGENCY CONDITIONS ARE ENCOUNTERED, SHUT OFF THE MAIN POWER IMMEDIATELY,

5., After 30 minutes, close the service valve fully. The air receiver will fill

to cut-out pressure and the motor will stop The unit is now ready for

use

GENERAL

Your air compressor was designed for f 00% continuous duty operation with the use of Ingersoll-Rand synthetic compressor lubricant and 60% continuous duty operation with the use of petroleum lubricant In other words, synthetic lubricant allows the compressor to pump continuously without cycling Petroleum lubricant limits the compressor to a maximum of 36 minutes of pumping time per hour The compressor should not cycle more than 10 times per hour
