N No otte e:: These service procedures require working with
refrigerant. Do not release refrigerant to the
atmosphere! The service technician must
comply with all federal, state, and local laws.
When leak-testing refrigerant systems, observe all
safety precautions. Leak test only one circuit at a time
to minimize system exposure to potentially harmful
moisture in the air.
Field Piping (Air-cooled Discharge and Liquid
Lines)
1. Ensure all required field-installed piping pressure
tests are completed in accordance with national
and/or local codes.
2. Close liquid line angle valve.
3. Connect R-410A refrigerant cylinder to high side
charging port (at Remote Condenser or field-
supplied discharge line access port). Add
refrigerant to reach pressure of 12 to 15 psig.
4. Disconnect refrigerant cylinder. Connect dry
nitrogen cylinder to high side charging port and
increase pressure to 150 psig. Do not exceed high
side (discharge) unit nameplate design pressure.
Do not subject low side (suction) components to
high side pressure.
5. Check all piping joints, valves, etc. for leaks.
Recommend using electronic detector capable of
measuring 0.1 oz/year leak rate.
6. If a leak is located, use proper procedures to
remove the refrigerant/nitrogen mixture, break
connections and make repairs. Retest for leaks.
7. Make sure all service valves are open.
