APPLICATION
The F52F Return Grille Electronic Air Cleaner is wall or
ceiling mounted in the main return air duct of a central forced
air heating, cooling, or ventilation system. It captures a
significant number of the airborne particles (0.5 microns and
larger) from the air circulated through the cell(s).

PLANNING THE INSTALLATION
Application and Construction
The air cleaner should be installed in the occupied space
return duct opening leading to a central air handling system.
All of the air circulated by the system must pass through the
electronic air cleaner.
The front door of the electronic air cleaner is hinged to
provide access to the internal components. See Fig. 4.
The air cleaner has one or two electronic cell(s) that must be
installed with the ionizer section (side with fine wires) facing
the door.

The cell(s) is held in place by metal hooks and a
quarter-turn latch.
A spring contact provides the electrical connection between
the solid state power supply and the electronic cell(s). An
interlock switch interrupts the line voltage to the power supply
when the door is opened. A rocker-type ON-OFF switch
allows the air cleaner to be turned off manually. An indicator
light that is on shows that the air cleaner is energized and the
power supply is producing high voltage.

Review Installation Requirements
The air cleaner is installed in place of the main return grille
so all the air circulated by the system passes through the
air cleaner.
It can be installed in either a wall or ceiling, but not in the
floor. See Fig. 5 through 7 for typical installations.

(Dotted lines show optional ductwork.)
In a wall installation, mount the one-cell air cleaner with the
door hinge on the bottom so the air cleaner fits between the
two studs 16 in. (407 mm) on center. The two-cell air cleaner
fits between two studs 24 in. (610 mm) on center when
mounted with the hinge on either side
or
between three 16 in.
studs, with center stud removed, when mounted with hinge on
the bottom.
Do not install either unit with the hinge on the top because the
cell(s) will be awkward to remove.
Determine Duct Design Requirements
The return duct should end at, or slightly behind, the finished
wall surface. Do not use a standard register flange, or the
door may not fit tightly against the wall.
Transitions
Transitions are needed when the duct is a different size than
the air cleaner. Gradual transitions reduce air turbulence and
increase efficiency. The transition should be 20 degrees or
about 4 in. per running ft (100 mm per 300 linear mm) or less
on each side of a transition fitting.

CAUTION
Electric Shock Hazard.
Can cause electrical shock or equipment damage.
Disconnect power before installing air cleaner.
Unpack the Air Cleaner
1. Check that all components are included. The unit
consists of:
• Door assembly in separate box.
• One metal mesh prefilter.
• One or two electronic cell(s).
• Literature package.
2. Lift out and set aside the door/grille assembly and the
prefilter. Turn the cell latch (Fig. 4) toward the air
cleaner cabinet and remove the electronic cell(s), lifting
from the side nearest the latch. Set aside.
3. Remove the four screws holding the wiring
compartment cover.
4. Remove the air cleaner cabinet from the carton.
Make Wall Opening
1. Size the wall opening to fit the air cleaner as closely as
possible with the air cleaner door hinge on either side
or bottom for the two-cell model, and on the bottom for
the one-cell model. See Table 1 for dimensions.
