Split System Models

Refrigerant charge requirements: Total refrigerant charge will be required only if units are evacuated during installation or maintenance. Total refrigerant charge = evaporator + lines + condensing unit.

NOTE

All condensing units and 3-ton evaporator units are fully charged with refrigerant. All 5 ton evaporator units include a nitrogen holding charge only. See Table 21 for field charge required. If field-supplied refrigerant piping is installed, refrigerant must be added to the system.

Once all piping is complete, check for leaks and dehydrate the field piping as follows:

1.Pressurize the field piping to 150 PSIG (1034 kPa) using dry nitrogen with a trace of refrigerant. Check system for leaks with a suitable leak detector.

2.After completion of leak testing, release the test pressure (per local code) and pull a deep vacuum on the field piping with a suitable pump.

3.After 15 minutes, check the pressure readings and, if they have not changed, break vacuum with dry nitrogen. Pull a second vacuum to 250 microns or less. Recheck the pressure after 15 minutes.
