Step 3--Provide Clearances
The required minimum service clearances are shown in Fig. 5 and
6. Adequate ventilation and outdoor air must be provided. The
outdoor fan draws air through the outdoor coil and discharges it
through the top fan grille. Be sure that the fan discharge does not
recirculate to the outdoor 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.
above the unit top. The maximum horizontal extension of a partial
overhang must not exceed 48 in.
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.
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. above the highest expected water and runoff
levels. Do not use unit if it has been under water.
Step 4--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
Prior to initial use, and at monthly 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
nmst not be used and should be discarded.
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal injury
or death.
Before installing or servicing system, always turn off main
power to system. There may be more than one disconnect
switch. Turn off accessory heater power switch if applicable.
Tag disconnect switch with a suitable warning label.
This bracket is to be used to rig/lift a Small Packaged Product onto
roofs or other elevated structures.
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.
USE OF RIGGING BRACKET
Field Installation of Rigging Bracket
1. If applicable, 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. 7). 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.
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).
Ri_in_/Liftin_ 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. 7).
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. After unit is securely in place detach rigging straps. Remove
corner posts, screws, and rigging brackets then reinstall
screws.
UNIT FALLING HAZARD
Failure to follow this warning could result in personal injury
or death.
Never stand beneath rigged units or lift over people.
INTRODUCTION
The lifting/rigging bracket is engineered and designed to be
installed only on Small Packaged Products.
UNIT FALLING HAZARD
Failure to follow this warning could result in personal
injury/death or property damage.
When straps are taut, the clevis should be a minimum of 36
inches above the unit top cover.
After the unit is placed on the roof curb or mounting pad, remove
the top crating.
