Unit Location
Recommendations
When selecting and preparing the unit
installation location, consider the
following recommendations.
1. Consider the unit weight. Reference
the unit weight on the unit nameplate
or in the Dimensions and Weights
section on pages 9–10.
2. Allow sufficient space for the
recommended clearances, access
panel removal, and maintenance
access. Refer to Figure I-PC-1.
3. The installer must provide threaded
suspension rods for ceiling mounted
units. All units must be installed level.
4. Coil piping and condensate drain
requirements must be considered.
Allow room for proper ductwork and
electrical connections. Support all
piping and ductwork independently of
unit to prevent excess noise and
vibration.
Skid Removal
The unit ships on skids that provide
forklift locations from the front or rear.
The skid allows easy maneuverability of
the unit during storage and
transportation. Remove the skids before
placing the unit in its permanent location.
Remove the skids using a forklift or jack.
Lift one end of the unit off of the skids.
Vibration isolators for external isolation
are field supplied.
Pre-Installation Checklist
Complete the following checklist before
beginning unit installation.
!
Verify the unit size and tagging with
the unit nameplate.
!
Make certain the floor or foundation is
level, solid, and sufficient to support the
unit and accessory weights. Reference
unit and accessory weights on pages
9–14. Level or repair the floor before
positioning the unit if necessary.
!
Allow minimum recommended
clearances for routine maintenance
and service. Refer to unit submittals for
dimensions.
!
Allow one and one half fan diameters
above the unit for the discharge
ductwork.
WARNING
Improper Unit Lift!
Test lift the unit approximately 24
inches to verify proper center of
gravity lift point. To avoid dropping of
unit, reposition lifting point if unit is
not level. Failure to properly lift unit
can result in serious injury, possible
equipment or property-damage, or
death.
Unit Handling Procedure
1. Position rigging sling under wood skid
using spreader bars to avoid unit
damage.
2. Use a forklift with caution to prevent
unit damage. The fork length must be at
least 68 inches long to safely fork the unit
from front or back.
3. The unit center of gravity will fall within
the center of gravity block at various
locations depending on unit options.
4. See unit nameplate for unit weight.

Rigging and Handling
Before preparing the unit for lifting,
estimate the approximate center of
gravity for lifting safety. Because of
placement of internal components, the
unit weight may be unevenly distributed,
with more weight in the coil area.
Approximate unit weights are given in
the Dimensions and Weights section
beginning on page 9. Also, you may
reference the unit weight on the unit
nameplate.
Before hoisting the unit into position, use
a proper rigging method such as straps,
slings, or spreader bars for protection
and safety. Always test-lift the unit to
determine the exact unit balance and
stability before hoisting it to the installa-
tion location.
