Installation; Step 1 - Check Equipment; Step 2 - Mount Unit - Carrier Performance 40MBDQ Series Installation Instructions Manual

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.
.
CAUTION
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.

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.

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.
