INSTALLATION
Check Equipment and Job Site
Unpack Unit
Move to final location. Remove carton taking care not to damage
unit.
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,
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. 2
to determine base pan size and knockout hole location,
For hurricane tie downs, contact distributor for details and PE
Certification (Professional Engineer), if required,
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 (8,05 kin/h)
may require wind bafiles. Consult the Service Manual -
Residential Split System Air Conditioners and Heat Pumps for
wind bafi]e construction,
NOTE: Unit must be level to within -2°(-3/8 in./ft,-9.5 nm:/m.)
per compressor manufacturer specifications.
Clearance Requirements
When installing, allow sufficient space for airflow clearance,
wiring, refrigerant piping, and service. Allow 24 in. (609.6 ram)
clearance to service end of unit and 48 in. (1219.2 mm) (above
unit. For proper airflow, a 6-in. (152.4 ram) clearance on 1 side of
unit and 12-in. (304.8 ram) on all remaining sides must be
maintained. Maintain a distance of 24 in. (609.6 ram) 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. (152.4 ram)
above roof surface.

Operating Ambient
The n:ininmm outdoor operating ambient in cooling mode is 55°F
(12.78°C), and the maximum outdoor operating ambient in cooling
mode is 120°F (48.89°C). The n:axinmm outdoor operating
ambient in heating mode is 66°F (18.89°C).
NOTE: Units operating at high stage operation, 208v (or below)
line voltage, and at an outdoor ambient of 120°F (48.9°C) (or
greater), may experience compressor thermal trip.
Check Defrost Thermostat
Check defrost thermostat to ensure it is properly located and
securely attached. There is a liquid header with a brass distributor
and feeder tube going into outdoor coil. At the end of the one of
the feeder tubes, there is a 3/8 in. O.D. stub tube approximately 2
in. long. (See Fig. 3.) The defrost thermostat should be located on
stub tube. Note that there is only one stub tube used with liquid
header, and on most units it is the bottom circuit.

Failure to follow this caution may result in equipment
damage or improper operation.
Do not allow water and/or ice to build up in base pan.
Elevate unit per local climate and code requirements to provide
clearance above estimated snowfall level and ensure adequate
drainage of unit.
