Ingersoll Rand Compressor SSR-HP20

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

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

SSR Ultra Coolant is a polyglycol base coolant. Change Ultra Coolant after every 8000 hours or every two years, whichever comes first.

SSR Food Grade Coolant is a polyalphaolefin base coolant. Change after every 1000 hours or every 6 months whichever comes first. Do not operate unit beyond this 1000 hour lubricant change interval, as lubricant degradation will occur.

In addition to the tools normally found in any reasonably equipped serviceman’s toolbox, the following items should be available at the work site:

1) Suitable drain pan and container to hold lubricant drained from unit.

2) A quantity of proper lubricant sufficient to refill the compressor.

Warning: This procedure requires trained personnel with PPE!

Disconnect tubing at each end of check valve/screen/orifice assembly

Check orifice and clean if required

Press screen retainer orifice from its mating fitting without damaging flared end of fitting or O-ring

Wash screen and housing in safety solvent and blow dry

Press the check valve/screen/orifice into fitting block

Assemble the check valve/screen/orifice assembly to the tubing lines

Sign off on the separator cleaning

Warning: Improper lubrication can be a cause of motor bearing failure. The quantity of grease added should be carefully controlled.

The smaller motors must be greased with a lesser amount of grease than larger motors.

When regreasing, stop motor. Disconnect power; lock out and tag.

Remove outlet plugs (or spring-loaded grease relief plugs if present).

The outlet plug may not be accessible on the fan end of some TEFC 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.

Warning: This procedure requires trained personnel with PPE!

Is the operating environment clean?

Is the inlet filter changed at prescribed intervals?

Is the operating environment extremely dirty?

Enter the current hours of operation

If the operating environment is dirty, change the filter more frequently.

Did you use a suitable device to loosen the old element?

Did you use a drain pan to catch any leakage during removal?

Did you discard the old element?

Inspect sheave grooves for foreign material or rubber build-up.

Clean and degrease sheaves before installing new belts.

Install new belts in the reverse order of disassembly.

When installing a new belt, ensure not to pry or force the belt over the sheave grooves.

At the center of the sheave span, apply a force (perpendicular to the span) by use of a tension gauge or other calibrated spring.

If the belt tension is incorrect, loosen the nut on the pivot bolt located on the left side (nearest the separator tank) on the airend. Then loosen the locknut on the tensioning bolt located on the right side of the airend.

Rotate the belt tensioning bolt clockwise until the proper belt tension is achieved, as measured by a belt tension gauge.
