Step 3ÐClearance Requirements

 

 

Step 6ÐMake Tubing Connections

 

 

When installing, allow sufficient space for airflow clearance, wiring, refrigerant piping, and service. Common clearances are 6 in. on 1 side, 12 in. on 2 sides, and 30 in. on service side of unit. Allow 24 in. between units. Discharge air must be unobstructed and must not recirculate.

Position so water, snow, or ice from roof or eaves cannot fall directly on unit.

On rooftop applications, locate unit at least 6 in. above roof surface. Place unit above a load-bearing wall and isolate unit and tubing set from structure.

Arrange supporting members to adequately support unit and minimize transmission of vibration to building. Consult local codes governing rooftop applications.

Step 4ÐOperating Ambients

The minimum outdoor operating ambient in cooling mode is 55°F, and the maximum outdoor operating ambient in cooling mode is 125°F.

Step 5ÐMetering Device

If unit is being installed with piston, check indoor coil piston to see if it matches the required piston shown on outdoor unit rating plate. If it does not match, replace indoor coil piston with piston shipped with outdoor unit. The piston shipped with outdoor unit is correct for any approved indoor coil combination.

Relieve pressure and recover all refrigerant before system repair or final unit disposal to avoid personal injury or death. Use all service ports and open all flow-control devices, including solenoid valves.

To prevent compressor damage DO NOT bury more than 36 in. of refrigerant tubing. If ANY tubing is buried, provide 6 in. vertical rise at service valve.

To prevent damage to unit or service valves observe the following:

·Use a brazing shield.

·Wrap service valves with wet cloth or use a heat sink material.

Connect outdoor unit to indoor sections using accessory tubing package or field-supplied tubing of refrigerant grade, correct size, and condition. Refer to Fig. 4 for refrigerant tube dimensions and connections. For tubing requirements beyond 50 ft, consult your local distributor or the Long-Line Application Guideline.

SWEAT CONNECTION

1.Consult local code requirements.

2.Connect tubing to fittings on outdoor unit vapor and liquid service valves.

3.Service valves are closed from factory and ready for brazing.
