Jobsite Storage

Indoor air handlers and field-installed accessories must be
protected from the elements. A controlled indoor
environment is recommended for proper storage.
Note: All factory shipping protection should be removed,
This wrapping is for transit protection only.
The unit controller and all other electrical/electronic
components should be stored in conditions of -20°F to
120°F and 5 to 95 percent relative humidity, non-
condensing. Electrical components are not moisture-
tolerant.
Outdoor units require no special protection for storage
prior to installation.

Outdoor Storage

NOTICE
Corrosion!
Plastic tarps can cause condensation to form in and on
the equipment, which could result in corrosion damage
or wet storage stains. Use only canvas tarps to cover air
handlers.
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. 161.
CLCH-SVX07K-EN
• 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 (see
approximate section weights; refer to the unit
submittals for actual weights).
• Allow sufficient space for adequate free air and
necessary service access (see
Recommendations," p.
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!
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. The floor or
foundation must be level and the condensate drain at
the proper height for proper coil drainage and
condensate flow.
• Confirm the roof curb or foundation of the mounting
platform is level 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.
"Fan Bearing
• If the unit integral base frame ceiling suspension
provisions are not used, the installer/contractor must
provide a ceiling-suspended mounting frame
"Dimensions and Weights," p. 11
11). Refer to submittals for
"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.
