•
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
Figure 2, p.
14.
1. Position the evaporator module and skid assembly
in its final location.
2. Remove the skids from under the unit. See
2, p.
14. If you find internal 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)
I I m m p p o o r r t t a a n n t t : : 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.
1. Cut appropriate sized "waffles" from the sheets
PKG-SVX027C-EN
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.

N N o o t t e e s s : :
•
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.
