Complete Wiring - Honeywell F50F Product Data

Position Cell Key
The electronic cell must always be installed so the ionizer
section is on the upstream side. A factory-installed cell key
on the bottom of the cabinet allows the cell to be inserted in
only one direction. If the arrow molded into the plastic key
points in the same direction as the airflow, the ionizer will
always be on the upstream side.
If the position of the key must be reversed, proceed as
follows:
1. Remove the electronic cell.
2. Remove the screw holding the cell key in place.
See Fig. 15.

Fig. 15. Position of cell key determines orientation of cell
(arrow on key must point downstream).
3. Turn the key around and place it over the opposite
holes. The tab on the bottom fits into the larger hole,
and the screw fits into the smaller hole. Make sure the
arrow on the key points in the direction of the air flow
(downstream).
4. Tighten the screw into the new hole.
5. Insert the electronic cell. The ionizer section will now
be on the air-entering (upstream) side of the cabinet.
Attach Cell Handle(s)
The cell handles are attached to the packing insert inside
the access door. They must be installed on the end of the
cell closest to the access door. To install:
1. Orient the cell as it will be when installed. The gray
contact board must be up and the airflow arrow
stamped into the cell must point downstream.
2. Hold the handle sideways and insert the solid tab on
the back of the handle into the slot in the cell. Turn the
handle 90 degrees clockwise to align the divided tab
with the square hole. See Fig. 16.

3. Insert the divided tab into the square hole.
4. Fold up the wedge and insert it into the divided tab to
lock the handle in place. If necessary, press with a
blunt instrument like the end of a pliers.
Reassemble Air Cleaner
Insert the electronic cell with the gray contact board
toward the power supply and the airflow arrow pointing
downstream. If the cell does not slide easily into the
cabinet, check the orientation of the cell key.
Insert the prefilter on the upstream side of the cabinet in
the guide provided.
Replace the access door. Insert the tab on the bottom of
the door into the slot in the cabinet, then swing it closed
and press into place. The door must be firmly in place or
the air cleaner will not operate.

WARNING
Electric Shock Hazard.
Can cause personal injury.
Do not use an extension cord.
• Assure all wiring complies with local codes and
ordinances.
• The line voltage power source must match the voltage
and frequency printed on the label inside the access
door.
• When the system fan comes on the Air Flow Switch
(AFS) senses the negative pressure in the duct and
turns the power supply on. If power to the air cleaner is
controlled by another switch the AFS can be disabled
by cutting the jumper on the back of the AFS circuit
board. See Fig. 17.
Plug the electronic air cleaner directly into the correct
voltage and frequency outlet. See Fig. 17 for internal
schematic. The air cleaner will operate properly with any
fan when wired with conduit or plugged in.
