Site Preparation - Trane BCHE Installation, Operation And Maintenance Manual

Pre-Installation
NOTICE
Unit Corrosion Damage!
Plastic tarps can cause condensation to form in
and on the equipment, which could result in
corrosion damage or wet storge stains.
Use only canvas tarps to cover air handlers.
• 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. Refer to the unit submittals for actual
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. 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.
• 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!
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
drainage and condensate flow. Standing water and
wet surfaces inside the equipment can become an
amplification site for microbial growth (mold). If
there is evidence of microbial growth on the
interior insulation, it should be removed and
replaced prior to operating the system.
• If the unit is to be ceiling mounted, the installer/
contractor must provide threaded suspension rods. All
units must be installed level.
• BCHE and BCVE 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 on the same side as the
piping. Size 24-60 BCVE units have piping on the front
of the unit.
• The fan wheel and main drain pan are easily removable
for cleaning.
