Planning the Installation
APPLICATION
The F50F is used in a forced air heating, cooling, or
ventilating system. It removes airborne particles such as
dust, soot, pollen, tobacco smoke and cooking smoke
from the air circulated through it. All models have an inter-
nal air flow switch to operate the F50F when the system
blower is on.
REVIEW INSTALLATION REQUIREMENTS
The air cleaner should be installed where all the air
passing through the system circulates through it. The best
location is in the return air duct next to the blower compart-
ment so the air cleaner can help keep the blower motor
and evaporator coils clean.
IMPORTANT: Do not mount in the discharge air duct.
For most efficient air cleaning, airflow must be spread
evenly across the face of the air cleaner. If the duct is a
different size than the air cleaner cabinet, gradual transi-
tions are recommended. If the duct turns sharply just be-
fore the air cleaner, turning vanes are recommended.
Applications with Air Conditioning
The air cleaner should be installed upstream from the
evaporator coil. The air cleaner will help keep the coil
clean, reducing maintenance.
