INSTALLATION
Step 1 - Check Equipment
Unpack the unit and move to the final location. Remove the 
carton, taking care not to damage the unit. Inspect the equipment 
for damage prior to installation. File a claim with the shipping 
company if the shipment is damaged or incomplete.
Locate the unit rating plate which contains the proper 
installation information. Check the rating plate to ensure the 
unit matches the job specifications.
.
Step 2 - Mount Unit
The unit can stand or lie on the floor, or hang from the ceiling 
or the wall. Allow adequate space for wiring, piping, and 
servicing of the unit. The 09K-48K size units can be mounted 
horizontally or vertically (upflow). The 58K units can be 
mounted horizontally.

Fig. 10 — Unit mounted vertically (upflow)
IMPORTANT: When the unit is installed over a finished 
ceiling and/or a living area, building codes may require the 
installation of a field-supplied secondary condensate pan under 
the entire unit.
Some localities may allow as an alternative, the running of a 
separate, secondary condensate line. Consult the local codes 
for additional restrictions or precautions.
Ceiling Mounting Options
Different ceiling types call for different mount applications. 
Wood
Place the wood mounting across the roof beam, then install the
hanging screw bolts.

New Concrete Bricks
Inlay or embed the screw bolts.
Fig. 12 — New Concrete Bricks
Original Concrete Bricks
Use an embedding screw bolt, crock, and stick harness.

Steel Roof Beam Structure
Install and use the supporting steel angle.

Ensure the ceiling grid is supported separately from the unit.
The ceiling grid must not be supported by any part of the unit or 
any associated wiring or piping work.
