5 .3 Placing the Air Filters
Air filters remove airborne particles from the cabin air
and keep the evaporator coil clean. Place one air filter,
either on the air conditioning unit or in the return air
grille, for each air conditioner unit. Refer to “General
Information” on page 4 for air filter placement.
5 .4 Placing the Grilles and Transition
Boxes
Install the supply air grille as high as possible in a location
that will provide uniform air distribution throughout the
cabin. Direct the grille louvres upward. Install the return
air grille as low and close to the air conditioning unit as
possible to ensure airflow to the evaporator.
Do not direct the supply air discharge towards the return
air grille, as this will cause the system to short cycle.
Allow for adequate clearance behind the supply air grille
for the transition box and ducting connection. Refer to
“Minimum Duct and Grille Sizes per BTU Capacity” on
page 5.
