Outdoor Storage

NOTICE:
Corrosion!
Use only canvas tarps to cover air handlers. Plastic
tarps can cause condensation to form in and on the
equipment, which could result in corrosion damage or
wet storage stains.
Outdoor storage is not recommended for units that will be
installed indoors. However, when outdoor storage is
necessary, several things must be done to prevent
damage:
Note: Keep the equipment on the original wooden blocks/
skid for protection and ease of handling.
• Select a well-drained area, preferably a concrete pad or
blacktop surface.
• Place the unit on a dry surface or raised off the ground
to assure adequate air circulation beneath the unit and
to assure no portion of the unit will contact standing
water at any time.
• Loosen the belt tension on the drive belts.
• Cover the unit securely with a canvas tarp.
• Do not stack units.
• Do not pile other material on the unit.

Long-Term Storage

For longer periods of storage, allow proper clearance
around the unit to perform periodic inspections and
maintenance on the equipment. While the unit is in
storage:
• Every two weeks, rotate the fan and motor shaft 30
revolutions by hand. Check for free rotation.
• Every six months, check fan shaft bearings and grease
lines. Add grease using a manual grease gun following
the lubrications recommendations in
Lubrication, " p. 77.
• Check the motor lubrication; remove and clean grease
plugs and check for the presence of moisture in the
grease. If moisture is present, remove the motor and
send it to an authorized repair shop for bearing
inspection/replacement. If no moisture if present, refer
to the motor manufacturer's lubrication
recommendation for proper lubrication.

Site Preparation

• Ensure the installation site can support the total weight
of the unit; refer to the unit submittals for weights.
• Allow sufficient space for adequate free air and
necessary service access. Refer to submittals for
specific minimums.

• Allow room for supply and return piping, ductwork,
electrical connections, and coil removal.
• Ensure there is adequate height for condensate drain
requirements. See
Note: If unit is installed in a mechanical room on a pad,
Microbial Growth!
The floor or foundation must be level and the
condensate drain at the proper height for proper coil
drainage and condensate flow. Standing water and wet
surfaces inside the equipment can become an
amplification site for microbial growth (mold), which
could cause odors and damage to the equipment and
building materials.
• Confirm the roof curb or foundation of the mounting
platform is level (+/- 1/8-inch overall) and large enough
to accommodate the unit. Refer to the unit submittals
for specific dimensions.
• Provide adequate lighting for maintenance personnel
to perform maintenance duties.
• Provide permanent power outlets in close proximity to
the unit for installation and maintenance.
• Depending upon job requirements, 120 Vac power
may need to be provided for the unit controller. Refer
to submittals for more information. A dedicated
15-amp circuit is recommended.
• Wiring for the air handler must be provided by the
installer and must comply with all national and local
electrical codes.
• The installer/contractor must provide a ceiling-
suspended mounting frame designed to support the
"Fan Bearing
length, width, and weight of the entire air-handling
unit. See
information.
• Rooftop curb-mounted units must be sealed tightly to
the curb. Use proper sealants and roof-to-curb sealing
techniques to prevent water and air leakage. Refer to
curb manufacturer's installation instructions for more
details.
• Preparation of the roof curb or pier mount and roof
openings should be completed prior to lifting the unit
to the roof.
"Drain Pan Trapping, " p.
inadequate height may necessitate core-drilling
the floor to attain proper trap height. Insufficient
height could inhibit condensate drainage and
result in flooding the unit and/or equipment room.
