Step 3 – Provide Clearances
The required minimum service clearances are shown in
.
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. (1219 mm) above the unit top. The
maximum horizontal extension of a partial overhang must not exceed 48
in. (1219 mm)
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 2 in.
(51 mm) above the highest expected water and runoff levels. Do not use
unit if it has been under water.
Step 4 – Field-Fabricate Ductwork
Secure all ducts to roof curb and building structure on vertical discharge
units. Do not connect ductwork to unit. For horizontal applications, unit
is provided with flanges on the horizontal openings. All ductwork should
be secured to the flanges. Insulate and weatherproof all external
ductwork, joints, and roof openings with counter flashing and mastic in
accordance with applicable codes.
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 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.
