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 “Fan Bearing
Lubrication” on page 143.
•
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
“Dimensions and Weights” on page 14
for approximate section weights; refer to the unit
submittals for actual weights).
•
Allow sufficient space for adequate free air and
necessary service access (see
“Service Clearances” on
page 14
). 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
“Drain Pan Trapping” on page 30
.
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 floor or foundation 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.
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.
