Ingersoll Rand Compressor SSR-MM37

To check condition of separator element, run compressor in full load mode and at rated pressure and select "SEPARATOR PRESSURE DROP" in display table. If display says "XX PSI", then no maintenance is required. If warning light is on and display says "CHG SEPR ELEMENT" then the separator should be replaced.

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.

Use a suitable wrench and remove the bolts that hold the tank cover in position. Remove cover by lifting up and away.

Carefully lift the separator element up and out of the tank. Discard the faulty element.

Clean the gasket surface on both the tank and its cover. Exercise care to prevent pieces of the old gasket from falling down into the tank.

Check the tank to be absolutely certain that no foreign objects such as rags or tools have been allowed to fall into the tank. Install replacement element down into the tank after checking the new element gaskets for possible damage. Center the element up within the tank.

Place the tank cover in its correct position and install bolts. Tighten the bolts in a cross-pattern to prevent over-tightening one side of the cover. An improperly tightened cover will likely result in a leak.

Choose the type of coolant used

Enter the hours of operation of the unit

Is the coolant filter element available?

If the coolant filter element is not available, order one and stop the procedure

Is the coolant drain hose available?

If the coolant drain hose is not available, order one and stop the procedure

If the unit is not shut down, shut it down and wait for the coolant to heat up

Warning: This procedure requires trained personnel with PPE!

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. A graduated cylinder showing cubic centimeters (cc) may be used, or a 35mm film canister can give a close approximation for 2 cubic inches when filled.

Add the recommended volume of the recommended lubricant.

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

Run motor for about 30 minutes before replacing outlet plugs or reliefs.

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.
