NOTES:

1.Tube diameters are for lengths up to 50 ft. For tubing lengths greater than 50 ft, consult the Application Guideline and Service Manual — Residential Split-System Air Conditioners and Heat Pumps Using Puron® Refrigerant.

2.Refrigerant tubes and indoor coils must be evacuated to 500 microns to minimize contamination and moisture in the system.

ADAPTER

Do not leave system open to atmosphere any longer than

 

minimum required for installation. POE oil in compressor is

extremely susceptible to moisture absorption. Always keep

SEAL

ends of tubing sealed during installation.

 

If ANY refrigerant tubing is buried, provide a 6 in. vertical

PISTON

rise at service valve. Refrigerant tubing lengths up to 36 in.

 

may be buried.

To prevent damage to unit or service valves observe the

 

following:

Outdoor units may be connected to indoor section using accessory tubing package or field-supplied refrigerant grade tubing of correct size and condition. For tubing requirements beyond 50 ft, substan- tial capacity and performance losses can occur. Following the recommendations in the Application Guideline and Service Manual for Residential Split-System Air Conditioners and Heat Pumps using Puron® Refrigerant to minimize losses. Refer to Table 1 for field tubing diameters. Refer to Table 2 for accessory requirements.

Refrigerant tubes and indoor coil must be evacuated to 500 microns to minimize contamination and moisture in the system.
