Carefully unpack the air handler. If the unit is
damaged, contact your local dealer/distributor.
Do not attempt to use the air handler if it
appears damaged.
The blower section is factory assembled and all
components are performance tested.
The air handler consists of a blower assembly
and controls in an insulated, galvanized steel
factory finished enclosure. Knockouts are
provided for electrical wiring entrance.
Inspect the following:
•
Check the air handler rating plate to confirm
specifications are as ordered.

handler must be immediately examined by
the receiving party before removal. If
damage is found, the receiving party must

damage (i.e. carton damage and/or product
damage), as well as contact the last carrier
immediately, preferably in writing,
requesting inspection by the carrier's agent.
