NOTES :

1. Hot gas lines should rise above refrigerant level in

condenser circuit. Double riser may be required

; check compressor minimum capacity.

2. Trap should be installed on hot gas lines to

prevent condenser oil and refrigerant vapor

migration from accumulating on compressor heads

during off cycle.

3. Pitch all horizontal lines downward in the direction

of refrigerant flow.

4. For piping length greater than 50 ft, provide support

to liquid and gas lines near connection to coil.

5. All piping must follow standard refrigerant piping

practices.
