Installation
IMPORTANT:
Effective January 1, 2015, all split system and packaged
air conditioners must be installed pursuant to applicable regional
efficiency standards issued by the Department of Energy.
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.
Rig and Mount Unit
Mount unit on a solid, level concrete pad. Position unit so water or ice
from roof does not fall directly onto unit. Use field-provided snow stand
or ice rack where prolonged subfreezing temperatures or heavy snow
occurs. If conditions or local codes require unit be fastened to a pad, use
six (6) field-supplied tie-down bolts to fasten through slots provided in
unit mounting feet.
Mounting on Roof
Mount unit on a level platform or frame at least 6 in. (152 mm)
above roof surface. Isolate unit and tubing from structure.
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.
NOTE:
Unit must be level to within ±2° (±3/8 in./ft.±9.5 mm/m) per
compressor manufacturer specifications.
Rigging
Keep the unit upright and lift unit using a sling. Use cardboard or
padding under the sling, and spreader bars to prevent sling damage to the
unit. See
. Install the unit so that the coil does not face into
prevailing winds. If this is not possible and constant winds above 25
mph are expected, use accessory wind baffle. See installation
instructions provided with the accessory kit.
NOTE:
Accessory wind baffles should be used on all units with
accessory low ambient temperature control.

Clearance Requirements
Single Unit Applications
:
With coil facing wall
: Allow 6” (152 mm) minimum clearance on coil
side and coil end and 20” (504 mm) minimum clearance on fan side.
Allow 24” (610 mm) minimum clearance on compressor end for service.
With Fan Facing Wall
: Allow 8” (203 mm) minimum clearance on coil
side and coil end and 20” (504 mm) minimum clearance on fan side.
Allow 24” (610 mm) minimum clearance on compressor end for service
when units are stacked or there is less than 40” (1016 mm) of clearance
above the unit. If there is 40” (1016 mm) clearance above unit and the
top panel is accessible for removal allow 8” (203 mm) minimum
clearance on compressor end for service.
Multi--Unit Applications
: Allow 24” (610 mm) minimum clearance
between fan and coil sides of multiple units. Arrange units so discharge
of one does not enter inlet of another. Allow 24” (610 mm) minimum
clearance on compressor end when units are stacked or there is less than
40” (1016 mm) of clearance above the unit. If there is 40” (1016 mm)
clearance above unit and the top panel is accessible for removal allow 8”
(203 mm) minimum clearance on compressor end for service.
When two units are installed end-to-end with the coil ends facing each
other, allow 12” (305 mm) minimum clearance between units.
IMPORTANT:
When installing multiple units, ensure the discharge air
from one unit is not drawn into another unit. When installing single or
multiple units in an alcove, roof well, or partially enclosed area, ensure
there is adequate ventilation to prevent recirculation of discharge air.
