Site Preparation - Trane UniTrane Installation, Operation And Maintenance Manual

Pre-Installation
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.
• Cover the unit securely with a canvas tarp.
NOTICE:
Corrosion!
To prevent corrosion damage or wet stains, use only
canvas tarps to cover air handlers. Plastic tarps can
cause condensation to form in and on the equipment.
• Do not stack units.
• Do not pile other material on the unit.

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 as shown in the Dimensions
and Weights chapter. Refer to submittals for specific
minimums.
• Allow one and one half fan diameters above the unit
before the discharge ductwork makes any turns.
• Allow room for supply and return piping, ductwork,
electrical connections, and coil removal. Support all
piping and ductwork independently of the unit to
prevent excess noise and vibration.
• Ensure there is adequate height for coil piping and
condensate drain requirements. See
Drain Connections, " p.
• Consider coil piping and condensate drain
requirements. Verify condensate line is continuously
pitched one inch per 10 feet of condensate line run to
adequately drain condensate.

• Confirm the floor or foundation is level. For proper unit
operation, the unit must be level (zero tolerance) in
both horizontal axis.
NOTICE:
Microbial Growth! (2 of 2)
Failure to follow instructions below could result in
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. Standing water and wet
surfaces inside the equipment can become an
amplification site for microbial growth (mold).
• If the unit is to be ceiling mounted, the installer/
contractor must provide threaded suspension rods. All
units must be installed level.
• Vertical recessed/concealed units require wall/ceiling
openings. Refer to submittal for specific dimensions
before attempting to install.
• Horizontal recessed/concealed units must meet the
requirements of the National Fire Protection
Association (NFPA) Standard 90A or 90B concerning
the use of concealed ceiling spaces as return air
plenums. Refer to the submittal for specific
dimensions of ceiling openings.
• Touch up painted panels if necessary. If panels need
paint, sanding is not necessary. However, clean the
surface of any oil, grease, or dirt residue so the paint
will adhere. Purchase factory approved touch up epoxy
paint from your local Trane Service Parts Center and
apply.
• Units have either right or left hand piping. Reference
piping locations by facing the front of the unit (airflow
discharges from the front). The control panel is always
on the end opposite the piping.
• The fan board assembly and main drain pan are easily
removable for cleaning. See the Routine Maintenance
chapter for more details on servicing.
