Ingersoll Rand Compressor SSR-MH37

Warning: This procedure requires trained personnel with PPE!

All 60 Hz ODP drive motors and all fan motors.

Grease relief along shaft can occur, precluding necessity of removing this plug if inaccessible.

The inlet grease gun fittings and outlet plugs (or spring-loaded reliefs) are located at each end of the motor housing.

The drive end reliefs protrude out the circumference of the lower portion of the end bell near a flange bolt.

The drive end outlet plugs are located just behind the flange in the air intake area at about the 5 or 6 o’clock position.

Free drain hole of any hard grease (use piece of wire if necessary).

Use a hand lever type grease gun.

Determine in advance the quantity of grease delivered with each stroke of the lever.

Tools Required: Open end wrench, Pliers

The screen/orifice assemblies are similar in appearance to a straight tubing connector and will be located between two pieces of 1/4 inch O.D. scavenge line tubing.

The main body is made from 1/2 inch hexagon shaped steel and the diameter of the orifice and a direction-of-flow arrow is stamped in flat areas of the hexagon.

A removable screen and orifice is located in the exit end of the assembly and will require cleaning.

To remove the screen/orifice, disconnect the scavenge line tubing from each end. Hold the center section firmly and use a pair of pliers to gently grasp the exit end of the assembly that seals against the scavenge line tubing.

Pull the end out of the center section while using care to prevent damage to the screen or sealing surfaces.

Clean and inspect all parts prior to reinstallation.

When the assembly is installed, confirm the direction of flow to be correct. Observe the small arrow stamped in the center section and ensure the direction flow to be from the separator tank to the airend.

Sign off on the separator cleaning

Clean cooler cores if discharge air temperature is excessive or if unit shutdown occurs on high air temperature.

Ensure that the compressor is isolated from the compressed air system by closing the isolation valve and venting pressure from the drip leg.

Ensure that the main power disconnect switch is locked open and tagged.

■ Air hose equipped with approved O.S.H.A. nozzle.

On units sold outside the U.S.A. consult local codes.

In very clean operating environments and where inlet filter is changed at the above prescribed intervals.

In extremely dirty environments change coolant, filters, and separator elements more frequently.

The coolant filter should be changed after the first 150 hours of operation and every 2000 hours thereafter, or when the coolant is being changed. In dirty operating environments the filter should be changed more frequently.

Use a suitable device and loosen the old element. Use drain pan to catch any leakage during removal. Discard old element.

Wipe the sealing surface of the filter with a clean, lint-free rag to prevent the entry of dirt into the system.

Remove the replacement element from its protective package. Apply a small amount of clean lubricant on the rubber seal and install the element.

Screw element/s on until the seal makes contact with the head of the filter assembly. Tighten approximately one-half turn additional.

Start unit and check for leaks.

Run compressor in full load mode and at rated pressure

Enter the display message from the 'SEPARATOR PRESSURE DROP'

If warning light is on and display says 'CHG SEPR ELEMENT', proceed with the following steps

Loosen the fitting that holds the scavenge tube into the tank and withdraw the tube assembly

Disconnect blowdown valve from elbow in tank cover

Disconnect tube from fitting on minimum pressure check valve

Loosen tube nut on same tube at aftercooler inlet then swing tube away from tank cover

Remove the bolts that hold the tank cover in position and remove cover

Lift the separator element up and out of the tank and discard the faulty element
