8. Use transition fittings where return air duct dimensions
do not match the air cleaners opening dimensions.
Gradual transitions are preferred for greatest efficiency.
Four inches per linear foot (approximately 20° angle)
should be allowed, space permitting.
9. Seal all joints in the return air system to prevent dust
from entering the air stream.
NOTE: Do NOT use a silicon based sealant. This
causes a coating on the FIELD CHARGER pins that will
decrease the efficiency of the air cleaner.
