Emerson 2 User Manual

An electrical failure will be indicated by a distinct pungent odor. If a severe burnout has occurred, the 

oil will be black and acidic. If a burnout does occur, correct the problem that caused the burnout and 

clean the system thoroughly using the proper procedure. It is important to note that successive burn-

outs of the same system are usually caused by improper cleaning.

There are two kits that can be used with a complete compressor burnout: Sporlan System Cleaner and 

Alco Dri-Kleener. Whichever kit is used, follow the manufacturer’s procedure.

Replacement compressors are available from your Liebert supplier. They will be shipped in a reusable 

crate to the job site as required by the service contractor.
Upon shipping a replacement compressor, the service contractor will be billed in full for the compres-

sor until the failed compressor has been returned to the factory.
The compressor should be returned in the same container used for shipping to the job. The possible 

damage causes or conditions that were found should be recorded by marking the compressor return 

tag.
1. Disconnect power.
2. Attach suction and discharge gauges to access fittings.
3. Recover refrigerant using standard recovery procedures and equipment. Use a filter drier when 

charging the system with recovered refrigerant.

4. Disconnect all electrical connections.
5. Remove failed compressor.

6. Install replacement compressor and make all connections.
7. Pressurize and leak test the system at approximately 150 PSIG (1034 kPa) pressure.
8. Follow manufacturer’s instructions for cleanout kits.

Damage to a replacement compressor caused by improper system cleaning constitutes 

abuse under the terms of the warranty, and the WARRANTY WILL BE VOIDED.

Avoid skin contact with the refrigerant and oils. Severe burns will result. 

Use long rubber gloves when handling contaminated parts.

Do not loosen any refrigeration or electrical connections before relieving system pressure from 

both sides of the compressor.

NOTE
Release of refrigerant to the atmosphere is harmful to the environment and is unlawful. 

The optional three-phase scroll compressor must rotate in the correct direction to ensure 

proper system operation. Wiring must be phased and connected as shown:
• PHASE “A” to T1 or Ll
• PHASE “B” to T2 or L2
• PHASE “C” to T3 or L3
