4.10 MOTOR LUBRICATION (Continued)

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.

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

2)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.

3)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.

4)Run motor for about 30 minutes before replacing out- let plugs or reliefs. BE SURE TO SHUT MOTOR

DOWN, DISCONNECT POWER, LOCK OUT AND TAG, AND REPLACE THESE DRAIN FITTINGS TO PRECLUDE LOSS OF NEW GREASE AND ENTRANCE OF CONTAMINANTS!

Recommended Motor Grease

60 Hz motors require:

Mobilith SHC 220 (39218193)

Use the grease as indicated on a special grease information nameplate on the motor. Use of alternative greases can result in shortened motor life due to incompatibility of greases. If there is not a grease nameplate on the motor use:

Chevron Black Pearl #2 (39204292) (Preferred)

Chevron SRI 2 (39161641)

50 Hz motors require

Esso Unirex N3 (92844729)

!WARNING

Hazardous voltage. Can cause severe injury or death.

Disconnect power before servicing.

Lockout/Tagout machine.

MOTOR BEARING MAINTENANCE (STORED UNITS)

To ensure that complete contact is maintained between the motor bearings and the bearing grease on units to be placed in storage for extended intervals, the following motor maintenance procedure should be adhered to:

1)Prior to placing a unit in storage, rotate the motor several revolutions by hand in the proper direction of rotation.

2)Thereafter, rotate the motor as described in Step 1 at three month intervals until such time as the unit is placed in service.

3)If the storage time is to exceed a total of nine (9) months duration, the compressor must be ordered with long term storage option.
