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.
