35. Install manifold gauges (WP 0014, Service).
36. Start refrigeration unit in cool mode and run for 10 minutes (TM 10-8415-222-10, Operating Procedures).
Check refrigerant charge by blocking off airflow to condenser coil until discharge pressure can be maintained
at 210 psig. Charge system with refrigerant as required (WP 0014, Service).
37. Shut down refrigeration unit (TM 10-8415-222-10, Operating Procedures).
CAUTION
A new compressor needs to be checked for oil level after usage. As compressor
operates for the first time, oil will migrate to various internal compressor passages.
As a result, oil level may need to be adjusted.
38. Check compressor oil level and service as required (WP 0016, Service).
39. Operate refrigeration unit to verify refrigeration cycles are operational after compressor replacement (TM 10-
