4.5 Ductwork
This coil is designed for a complete supply and return ductwork system.
Do not operate the unit without all ductwork completed.
Do not operate this product without all ductwork 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.
Return ductwork: Do not terminate 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 coil.
Return Air Filters: Each installation must include a return air filter. This filtering may
be performed at the coil or externally such as a return air filter grille.
4.6 Unit Installation
Risk of explosion or fire.
Can cause injury or death.
Install the furnace or blower and condensing unit according to the installation
instructions provided with the unit.
Position the cased coil on top of the furnace or blower cabinet and secure it using
field-provided screws.
NOTE: If the coil is to be installed on an oil furnace, it may be necessary to install a
field-installed transition between the furnace and the coil to prevent airflow restriction
and possible damage to the coil drain pan. See the oil furnace installation instructions
for details.
