Ductwork and Filter:
Installation:
Design and install air distribution system to comply with
Air Conditioning Contractors of America manuals or
other approved methods that conform to local codes
and good trade practices.
When furnace supply ducts carry air outside furnace
area, seal return air duct to furnace casing and
terminate duct outside furnace space.
Install air conditioning cooling coil (evaporator) on
downstream side (in the supply air plenum) or furnace.
If separate evaporator and blower unit is used, install
good sealing dampers for air flow control. Cold air from
the evaporator coil going through the furnace could
cause condensation and shorten furnace life.
CAUTION
Dampers (purchased locally) MUST be
automatic.
WARNING
WARNING
Poison carbon monoxide gas hazard.
Do NOT draw return air from inside a
closet or utility room. Return air duct
MUST be sealed to furnace casing.
Failure to properly seal duct can result in
death, personal injury and/or property
damage.
WARNING
WARNING
Poison carbon monoxide gas hazard.
Install evaporator coil on the supply side of
the furnace ducting.
Evaporator coil installed in return side
ducting can cause condensation to form
inside heat exchanger resulting in heat
exchanger failure. This could result in
death, personal injury and/or property
damage.
