*For 460 Volt units add 14 lb (6.35 kg) to the rigging weight.
NOTE: See dimensional drawing for corner weights.
Fig. 5 -- 48EZ--A Suggested Rigging
Ducts passing through an unconditioned space must be insulated
and covered with a vapor barrier.
If a plenum return is used on a vertical unit, the return should be
ducted through the roof deck to comply with applicable fire codes.
See unit rating plate for any required clearances around ductwork.
Cabinet return--air static shall not exceed --.25 IN. W.C.
Step 4 — Provide Clearances
The required minimum operating and service clearances are shown
in Fig. 2 and 3.
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 that the fan discharge
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 mm) above the unit top. The maximum
horizontal extension of a partial overhang must not exceed 48--in.
(1219 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. The unit may be installed
on Class A, B, or C roof covering materials. Slab mounted units
should be at least 4--in. (102 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
PERSONAL INJURY OR PROPERTY DAMAGE
HAZARD
Failure to follow this warning could result in personal
injury, death or property damage.
When installing the unit on a rooftop, be sure the roof will
support the additional weight.
!
WARNING
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.
