3.5.3Dehydration/Leak Test and Charging Procedures for R22 (Standard) or R407C (Optional) Lee-Temp Control Type Condenser

! CAUTION

All local codes for handling refrigerant must be followed.

NOTE

As R22 and R407C are similar in properties, proper safety equipment and proper refrigeration tools are required on both types. Check unit nameplate for correct refrigerant type before topping off or recharging a system.

NOTE

Refrigerant R407C uses a POE (polyol ester) lubricant. The R407C refrigerant must be introduced and charged from the cylinder only as a liquid.

NOTE

When installing field piping, care must be taken to protect all refrigerant lines from the atmosphere, especially when using refrigerants with POE oils. Do not allow the piping to stand open to air for more than 15 minutes. Units designed for R407C have a compressor which contains POE oil that is very hygroscopic; that is, it quickly absorbs water from the air. The longer the compressor piping is left open to air, the harder it will be to fully evacuate. If left open too long, the POE oil may need to be replaced before achieving the required vacuum level.
