* Installation
When installing your new compressor, you may need additional copper fittings and tubing in some older model compressors when retro-fitting to new upgraded compressor models.
* Compressor Performance:
BtuH Ratings are based 0n 45 F evaporating temperature 130 F, condensing temperature, 65 F return gas temperature and 95 F, liquid temperature.

* IMPORTANT!!! - PLEASE NOTE: IDENTIFYING COMPRESSOR FAILURES
Most compressors fail due to system malfunctions, which must be corrected to prevent repeat failures. After a compressor fails, field examination of the failed compressor often will reveal symptoms of system problems. Proper corrections will help eliminate future failures.
* SINGLE PHASE BURN
Two phases of a three-phase motor overheated or burned as a result of the contactor opening only one of its contacts.
Correction:
(1) Replace contactors with properly sized contactors.
(2) Check for proper motor protection.
* HALF WINDING SINGLE PHASE BURN
In a two contactor application, two phases of one half of a three phase motor overheated or burned as a result of one contactor opening only one contact.
Correction:
(1) Replace contactors with properly sized contactors.
* HALF WINDING BURN
Half of all phases on a two contactor three phase motor are overheated or burned due to only one contactor opening.
Correction:
(1) Replace contactors with properly sized contactors.
(2) Check for feed back circuit holding one contactor closed.
* PRIMARY SINGLE PHASE BURN
Only one phase of a three phase motor is overheated or burned as the result of opening one phase on the primary side a delta to wye transformer.
Correction:
(1) Check primary side of a delta to wye main power transformer.
* START WINDING BURN
The start winding only of a single-phase motor is uniformly overheated or burned.
Correction:
(1) Check for proper wiring of compressor.
(2) Check starting capacitor and/or starting relay.
(3) Correct compressor overloading.
* SPOT BURN
A localized burn within a winding, between windings, or from windings to ground. If not the result of mechanical problems, check for spikes or surges of high current flow.
* SHORTED TERMINALS
A break down of the insulation between terminals and compressor body generally the result of over torque terminals.
