Outdoor Storage
Outdoor storage is
not
recommended for units that will be
installed indoors. When outdoor storage is necessary,
several things must be done to prevent damage:
Note:
Keep the equipment on the original 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
.
•
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 the Dimensions and Weights chapter
for approximate section weights; refer to the unit
submittals for actual weights).
•
Allow sufficient space for adequate free air and
necessary service access (see
). 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,
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.
•
Confirm the roof curb, floor, 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.
•
Wiring for the air handler must be provided by the
installer and must comply with all national and local
electrical codes.
•
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
CLCH-SVN-006*-EN Performance Climate Changer Air
Handler Model UCCA Roof Curb Installation.
Note:
Preparation of the roof curb or pier mount and roof
openings should be completed prior to lifting the
unit to the roof.
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.
NOTICE
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.
