Install compressor access panel and route manifold hoses through refrigerant gauge access holes.

Turn on power to the unit and allow the system to run for 5 to 10 minutes to stabilize operating conditions.

Measure airflow across the indoor coil and compare with fan performance data.

Compare discharge pressure and liquid temperature to the Charging Charts.

Add or remove refrigerant (liquid only) as required to obtain correct discharge pressure and liquid temperature.

Check suction line superheat and condenser sub-cooling to ensure proper operation.

Ensure only dry nitrogen with a pressure regulator is used for pressurizing unit.

Confirm no use of acetylene, oxygen, or compressed air for pressure testing.

Verify no use of open flame for gas leak detection.

Complete brazing operation of refrigerant lines to both outdoor and indoor units.

Pressurize the system through the service valve with dry nitrogen to 200 psi.

Check all field joints for leaks using soap bubbles or other methods.

If leaks are found, release pressure, repair, and repeat leak test.
