Ingersoll Rand Air Compressor SSR-EP75

CAUTION! Shut down the compressor, close the service air line isolation valve and open the main electrical disconnect switch. Confirm all air pressure is relieved from receiver.

Differential pressure across the element reaches three times the initial pressure drop or a maximum of 15 psi at full load?

Differential pressure dropped to zero?

Disconnected the scavenge tube at the airend?

Loosened the fitting that holds the scavenge tube into the tank and withdrawn the tube assembly?

Disconnected the piping from the receiver cover?

Removed the bolts that hold the tank cover in position and removed cover by lifting up and away?

Lifted the separator element up and out of the tank and discarded the faulty element?

Cleaned the gasket surface on both the tank and its cover?

Induction-type squirrel cage motor lubrication

The motor has anti-friction ball or roller bearings front and rear. At extended intervals they require relubrication.

The periods between re-greasings of the motor bearings can vary, primarily with the severity of the service conditions under which the motor operates.

For severe duty - Dusty locations - High Ambients, reduce time intervals in table above to 1/3 the listed value.

Enter the hours of operation since last lubrication

Was the lubrication successful?

Sign off on the motor lubrication

With the unit not running, coolant should appear in the sight glass.

With the unit running unloaded and the coolant at operating temperature.

The coolant level should be at midrange in the sight glass.

Sign off on the coolant level check

CAUTION! Grease should only be added when the motor is stopped and power disconnected.

Motor stopped and power disconnected?

When regreasing, stop motor and remove inlet and outlet plugs.

Inlet and outlet plugs removed?

Inlet grease gun fittings and spring-loaded outlets are arranged at each end on the motor housing. Use a hand lever type grease gun.

Hand lever type grease gun used?

Determine in advance the quantity of grease delivered with each stroke of the lever. Add grease in the following quantity: 3/4 cu. in. or 0.6 oz. (13.0 c.c. or 18 grams)

Quantity of grease delivered with each stroke of the lever

Do not expect grease to appear at the outlet, but if it does discontinue greasing at once.

Warning: Care should be exercised during these lamp checks because of the electrical hazards that will be present when the electrical box is open.
