Step 4 — Pr ovide Clearances
The required minimum operating and service clearances are shown
in Fig. 3 and 4. Adequate combustion, ventilation and condenser
air must be provided.
IMPORTANT: Do not restrict outdoor airflow. An air restriction
at either the outdoor--air inlet or the fan discharge may be
detrimental to compressor life.
The condenser fan pulls air through the condenser coil and
discharges it through the top grille. Be sure t hat the fan dischar ge
does not recirculate to the condenser coil. Do not locate the unit in
either a corner or under an overhead obstruction. The minimum
clearance under a partial overhang (such as a normal house
overhang) is 48--in. (1219.2 mm) above the unit top. The
maximum horizontal extension of a partial overhang must not
exceed 48--in. (1219.2 mm).
Do not place the unit where water, ice, or snow from an overhang
or roof will damage or flood the unit. Do not install the unit on
carpeting or other combustible materials. Slab--mounted units
should be at least 4 in. (101.6 mm) above the highest expected
water and runoff levels. Do not use unit if it has been under water.
Step 5 — Rig and Place Unit
Rigging and handling of this equipment can be hazardous for
many reasons due to the installation location (roofs, elevated
structures, etc.).
Only trained, qualified crane operators and ground support staff
should handle and install this equipment.
When working with this equipment, observe precautions in the
literature, on tags, stickers, and labels attached to the equipment,
and any other safety precautions that might apply.
Training for operators of the lifting equipment should include, but
not be limited to, the following:
1. Application of the lifter to the load, and adjustment of the
lifts to adapt to various sizes or kinds of loads.
2. Instruction in any special operation or precaution.
3. Condition of the load as it relates to operation of the lifting
kit, such as balance, temperature, etc.
Follow all applicable safety codes. Wear safety shoes and work
gloves.
Inspection
The lifting/rigging bracket is engineered and designed to be
installed only on Small Packaged Products. This bracket is to be
used to rig/lift a Small Packaged Product onto roofs or other
elevated structures.
Prior to initial use, and at m onthly intervals, all rigging brackets
and straps should be visually inspected for any damage, evidence
of wear, structural deformation, or cracks. Particular attention
should be paid to excessive wear at hoist hooking points and load
support areas. Brackets or straps showing any kind of wear in these
areas must not be used and should be discarded.
UNIT FALLING HAZARD
Failure to follow this warning could result in personal
injury or death.
Never stand beneath rigged units or lift over people.

WARNING
PROPERTY DAMAGE HAZARD
Failure to follow this warning could result in personal
injury/death or property damage.
Rigging brackets for one unit use only. When removing a
unit at the end of its useful life, use a new set of brackets.

WARNING
Use of Rigging Bracket
Field Installation of Rigging Bracket (if not already installed)
1. Remove unit from shipping carton. Leave top shipping skid
on the unit for use as a spreader bar to prevent the rigging
straps from damaging the unit. If the skid is not available,
use a spreader bar of sufficient length to protect the unit
from damage.
2. Remove 4 screws in unit corner posts.
3. Attach each of the 4 metal rigging brackets under the panel
rain lip (See Fig. 6). Use the screws removed in step 2
above to secure the brackets to the unit.
PROPERTY DAMAGE HAZARD
Failure to follow this warning could result in personal
injury/death or property damage.
Rigging bracket MUST be under the rain lip to provide
adequate lifting.

WARNING
PROPERTY DAMAGE HAZARD
Failure to follow this warning could result in personal
injury/death or property damage.
Do not strip screws when re--securing the unit. If a screw is
stripped, replace the stripped one with a larger diameter screw
(included). When straps are taut, the clevis should be a
minimum of 36 in. (914.4 mm) above the unit top cover.
!
WARNING
Rigging/Lifting of Unit
1. Bend top of brackets down approximately 30 degrees from
the corner posts.
2. Attach straps of equal length to the rigging brackets at
opposite ends of the unit. Be sure straps are rated to hold the
weight of the unit (See Fig. 6).
3. Attach a clevis of sufficient strength in the middle of the
straps. Adjust the clevis location to ensure unit is lifted level
with the ground.
4. Remove corner post screws and rigging brackets, then
re--install screws.
After the unit is placed on the roof curb or mounting pad, remove
the top crating.
