Compressor Replacement - Liebert nteleCool 2 User Manual

Mechanical Failure
A mechanical compressor failure will not be indicated by a burned odor. The motor will attempt to
run. If you have determined that a mechanical failure has occurred, the compressor must be replaced.
Electrical Failure
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.
NOTICE
Risk of contaminated system. Can cause equipment damage.
Damage to a replacement compressor caused by improper system cleaning constitutes abuse
under the terms of the warranty, and the WARRANTY WILL BE VOIDED.
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.
CAUTION
!
Risk of caustic material. Can cause personal injury.
Avoid skin contact with the refrigerant and oils. Severe burns will result. Use long rubber
gloves when handling contaminated parts.

Compressor Replacement

Replacement compressors are available from your Emerson supplier. They will be shipped in a reus-
able 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.
CAUTION
!
Risk of explosive discharge of refrigerant. Can cause personal injury or equipment damage.
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.
Refrigerant must be recycled or discarded in accordance with federal, state, and local
regulations.
