Unit Installation
Ductwork
IMPORTANT
You must use a compatible heat kit listed in the above chart. Using an incorrect size, could cause the
unit to overheat and/or cause equipment damage.
This air handler is designed for a complete supply and return ductwork system.
Return ductwork:
Do not dispose of the return ductwork in an area that can introduce toxic or objectionable fumes/odors
into the ductwork. The return ductwork is to be introduced into the air handler bottom (upflow
configuration).
Return Air Filters:
Each installation must include a return air filter for the air handler or externally using a return air filter grille.
WARNING
DO NOT operate the unit without all ductwork completed and attached.
• Inadequate ductwork that restricts airflow can result in improper performance and compressor
or heater failure.
• Ductwork is to be constructed in a manner that limits restrictions and maintains suitable air
velocity.
• Ductwork is to be sealed to the unit in a manner that will prevent leakage.
Electric Heat Kit Installation (Optional)
The air handlers listed in this manual do not have a factory installed electric heater. An electric heat kit is
available as an optional accessory. The only heat kits that can be used are
MHK**U series listed in the table
below. Please refer to installation instructions provided with the heat kit, and in this manual, for the correct
installation procedure.
WARNING
• The electrical characteristics of the air handler, electric heat kit, and the power supply should be
identical. This air handler does not have a factory installed electric heat kit, however, they are
available as an optional accessory. If you plan to install a heat kit, only those in series indicated below
can be used. DO NOT use an electric heat kit other than those recommended below.
NOTE: When the electric heat kit is turned on, the fan of the air handler must also be on.
