Warning: Do not use oxygen or a mixture of R-22 and air to build up pressure as an explosion can occur causing serious personal injury.

Enter the initial pressure of the system in psig

Enter the pressure after adding refrigerant in psig

Enter the pressure after adding dry nitrogen in psig

Leak test with an electronic leak detector passed?

Water flow through the vessels maintained during the procedure?

Any leaks found in welded or brazed joints?

Is it necessary to replace a gasket?

If any leaks are found in welded or brazed joints, or it is necessary to replace a gasket, relieve the test pressure in the system before proceeding.

At every inspection, the oil, suction, and discharge pressures should be noted and recorded, as well as condenser and chiller water temperatures.

The suction line temperature at the compressor should be taken at least once a month.

Warning: Only fully qualified technicians must attempt service.

Power factory correction capacitors disconnected?

1) Re-sample after 500 hours of unit operation.

a) If content increases less than 10%, change oil and oil filter and re-sample at normal interval (usually annual).

b) If content increases between 11% and 24%, change oil and oil filter and re-sample after an additional 500 hours of operation.

c) If content increases more than 25%, inspect compressor for cause.

2) Re-sample after 500 hours of unit operation.

a) If content increases less than 10%, change filter-drier and re-sample at normal interval (usually annual).

b) If content increases between 11% and 24%, change filter-drier and re-sample after an additional 500 hours of operation.

c) If content increases more than 25%, monitor for a water leak.
