Operation; Inspect The Installation - Honeywell F50F Installation Instructions Manual

F50F DUCT MOUNTED ELECTRONIC AIR CLEANER
Alternatively, the F50F can be wired with conduit.
1. Open access door.
2. Remove and retain the (2) screws from the front of
the power box and the (2) screws from the sides of
the power box. See Fig. 13.
3. In the power box, remove and retain (2) wire nuts that
connect the line cord leads to the power box wiring.
4. Remove the green lead from the green grounding
screw on the wiring compartment barrier.
5. Remove the power cord and the strain relief.
6. Install plug (provided in bag assembly) in the hole
left by the power cord.
7. Attach conduit through a power box side knockout.
8. Wire the air cleaner directly to line voltage using wire
nuts. See Fig. 14. Secure ground connection to the
green ground screw on the wiring compartment
barrier.
9. Replace power supply cover and access door.

OPERATION

Large particles (lint, hair) are caught by the prefilter. As the
dirty air passes through the intense high voltage electric
field surrounding the ionizer wires, all particles are given
an electrical charge. The air then moves through the
collector part of the cell where alternate parallel plates are
charged positively and negatively, creating a uniform
electrostatic field. The charged particles are attracted to
and collect on the plates having the opposite electrical
charge. The air leaving the air cleaner has fewer particles.
Each time the air circulates through the F50F, more
particles are removed.
CHECKOUT

Inspect The Installation

Make sure:
• Turning vanes and transitions, as needed, are
properly installed.
• Sheet metal joints between air cleaner and furnace
are sealed.
• All sheet metal connections are complete.
• Original furnace filter has been removed and the blower
compartment cleaned.
• If an atomizing humidifier is installed upstream from the
air cleaner, a disposable furnace filter is installed
between the humidifier and the air cleaner.
• Outside air, if used, is mixed with return air or heated,
as necessary, before it can reach the air cleaner.
• The airflow arrows on the electronic cell point
downstream.
• The prefilter is on the upstream side of the cell.
• The cell handle faces outward.
• The electronic cell and prefilter are clean and dry.
• That W8600F (if included) wiring connections are
properly made.
Check Air Cleaner Operation
With all components in place, turn on the air cleaner switch
and energize the system blower. Check the following
points of operation:
1. The neon light next to the on-off switch is on. If a
W8600F is part of the installation, also check the
wall panel and make sure ON is indicated. The
W8600F FAULT indicator will come on if there is a
problem with the high voltage power supply.
2. Turn off the system blower. The neon light should go
off after a few seconds. The neon light shows that
the air cleaner is energized and the high voltage
power supply is working properly.
3. Turn on the system blower. With the air cleaner
energized, push the test button. A snapping sound
indicates that the collector voltage is present on the
cell. On air cleaner with a W8600F, the FAULT
indicator will come on when the test button is held
down.
4. With a multispeed blower, repeat steps 1-3 for each
fan speed.
5. If operation is not as described, refer to the Trouble-
shooting and Service section.
