B. Inspect Equipment

File claim with shipping company prior to installation if shipment is damaged or incomplete. Locate unit-rating plate on unit-corner panel. It contains information needed to properly install unit. Check rating plate to be sure unit matches job specifications.

II. INSTALL ON A SOLID, LEVEL MOUNTING PAD

If conditions or local codes require the unit be attached to pad, tie-down bolts should be used and fastened through knockouts provided in unit base pan. Refer to unit-mounting pattern in Fig. 3 to determine base-pan size and knockout-hole location.

On rooftop applications, mount on level platform or frame. 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.

Roof-mounted units exposed to winds above 5 mph may require wind baffles to achieve adequate defrost. Consult Low-Ambient Guideline for wind-baffle construction.

NOTE: Unit must be level to within ± 2 ° (± 3/8 in./ft) per compressor manufacturer specifications.

III. CLEARANCE REQUIREMENTS

When installing, allow sufficient space for airflow clearance, wiring, refrigerant piping, and service. Allow 30-in. clearance to service end of unit and 48 in. above unit. For proper airflow, a 6-in. clearance on 1 side of unit and 12 in. on all remaining sides must be maintained. Maintain a distance of 24 in. between units. 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.

IV. OPERATING AMBIENTS

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

V. CHECK INDOOR CHECK-FLO-RATER™ 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.

CAUTION: Remove indoor-coil piston if unit is to be installed on system with a TXV-metering device.

VI. MAKE PIPING CONNECTIONS

WARNING: 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.

CAUTION: If ANY refrigerant tubing is buried, pro- vide a 6-in. vertical rise at service valve. Refrigerant- tubing lengths up to 36 in. may be buried without further consideration. For lengths above 36 in., consult your local distributor.

CAUTION: 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.

Outdoor units may be connected to indoor unit using accessory- tubing package or field-supplied refrigerant-grade tubing of cor- rect size and condition. For tubing requirements beyond 50 ft, substantial capacity and performance losses can occur. Following the recommendations in the Residential Split-System Long-Line Application Guideline will reduce these losses. Refer to Table 1 for field-tubing equivalent-line length. Refer to Table 2 for accessory requirements.
