INSTALLATION

I. CHECK EQUIPMENT AND JOB SITE

A. UNPACK UNIT

Move to final location. Remove carton, taking care not to damage unit.

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.

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.

CAUTION: Do not allow POE lubricant to come into contact with roofing material. POE may deteriorate cer- tain types of synthetic roofing.

Roof mounted units exposed to winds above 5 mph may require wind baffles. Consult the Application Guideline and Service Manual for Residential Split System Air Conditioners and Heat Pumps using Puron® Refrigerant 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 AMBIENT

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

V. ELEVATE UNIT

CAUTION: Accumulation of water and ice in base pan may cause equipment damage.

Elevate unit per local climate and code requirements to provide clearance above estimated snowfall level and ensure adequate drainage of the unit. Fig. 4 shows unit with accessory support feet installed. Use accessory snow stand in areas where prolonged freezing temperatures are encountered. Refer to separate Installa- tion Instructions packaged with accessories.
