Unit Handling

WARNING
Risk of Unit Dropping!
Failure to properly lift unit in a LEVEL position could
result in unit dropping and possibly crushing operator/
technician which could result in death or serious injury,
and equipment or property-only damage.
Test lift unit approximately 24 inches (61 cm) to verify
proper center of gravity lift point. To avoid dropping of
unit, reposition lifting point if unit is not level.
• Unit can be moved into space using 4-wheel Dollies,
Hand Truck, or Pallet Jack.
• Be careful not to damage cassette bottom panel during
movement.
• The unit was designed so that all components can be
moved through a standard commercial width doorway
and make a turn in a standard commercial width
hallway. Certain circumstances may still require the
Evaporator Cassette to be disassembled to move it into
the mechanical room. For disassembly instructions,
please contact MJC Sales at (770) 988 8338.

Installation Preparation

Before installing the unit, perform the following
procedures to ensure proper unit operation, refer
p. 14.
1. Position the evaporator module and skid assembly in
its final location.
2. Remove the skids from under the unit. See
unit shipping package," p.
damage, file a claim immediately to the delivering
carrier.
3. Remove the protective shipping covers from the
cassettes.
4. Set the evaporator into place before proceeding. Place
the evaporator on the isolator pads (see next section)
if the unit has the isolator option.
Unit Vibration Isolator Option
(Isopads)
Important: Vibration isolation is not necessary for the
unit since the factory internally isolates the
compressors, thus creating double
isolation. Trane strongly recommends that
you consult a vibration specialist when
considering double isolation. In general,
Trane does not recommend double-
isolation.

14. If you find internal
1. Cut appropriate sized "waffles" from the sheets
provided. In general, a 2x2 pattern works well under
each cassette.
2. Place the pads at each intersection of the Condensing
Unit Cassettes.
3. Align the remaining pads along the back side (filter
side) of the Evaporator Cassette.

Notes:
• The unit is equipped with a positively sloped drain pan
to help indoor air quality (IAQ) and does not require
one corner of the unit to be pitched.
• Unit is not internally trapped. Installer must externally
trap the condensate line.
