WARNING

PERSONAL INJURY AND ENVIRONMENTAL

HAZARD

Failure to follow this warning could result in personal

injury or death.
Relieve pressure and recover all refrigerant before

system repair or final unit disposal Use all service

ports and open all flow--control devices, including

solenoid valves.

CAUTION

!

UNIT DAMAGE HAZARD

Failure to follow this caution may result in equipment

damage or improper operation.
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

ends of tubing sealed during installation.

CAUTION

!

UNIT DAMAGE HAZARD

Failure to follow this caution may result in equipment

damage or improper operation.
If ANY refrigerant tubing is buried, provide a 6 in. vertical

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

may be buried without further special consideration. Do

not bury lines longer than 36 in.

CAUTION

!

UNIT DAMAGE HAZARD

Failure to follow this caution may result in equipment

damage or improper operation.
To prevent damage to unit or service valves observe the

following:

S

Use a brazing shield.

S

Wrap service valves with wet cloth or use a heat sink

material.

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 80 ft., substantial capacity and performance losses can

occur. Following the recommendations in the Application
Guideline and Service Manual--Residential Split--System Air

Conditioners and Heat Pumps Using Puron Refrigerant will

reduce these losses. Refer to Table 1 for field tubing diameters.
Refer to Table 2 for accessory requirements.
There are no buried--line applications greater than 36 in.
If refrigerant tubes or indoor coil are exposed to atmosphere, they

must be evacuated to 500 microns to eliminate contamination and
moisture in the system.

OUTDOOR UNIT CONNECTED TO FACTORY
APPROVED INDOOR UNIT:

Outdoor unit contains correct system refrigerant charge for
operation with factory approved ARI rated indoor unit with

highest sales volume when connected by 15 ft. of field--supplied

or factory--accessory tubing, and factory supplied filter drier.
Check refrigerant charge for maximum efficiency.
