Honeywell Electronic Air Cleaner F300B 16x25

To assure optimum performance from the air cleaner, the cells and prefilters must be cleaned regularly and the postfilters replaced regularly—twice a year with normal use or more frequently with heavy use.

Washing frequency varies, depending on the number of family members, pets, activities (such as cooking or woodworking) and smoking habits.

NOTE: To let the heating or air conditioning system operate normally while the cells are being washed, simply turn off the air cleaner switch.

1. The quickest and easiest way to clean your prefilter is to use the brush attachment of your vacuum cleaner to vacuum the lint off the dirty side of the prefilter.

Greasy dirt may require soaking the prefilter in a tub or rinsing with the garden hose. Do not wash the prefilter in the dishwasher or car wash.

2. The prefilter should be cleaned every 6 months or more frequently with heavy use. This will keep the prefilter clean of air choking lint that can make your system work harder.

Cleaning your Cells • A quick cleaning of the cells can be done by simply wiping down the ionizer wires with a damp cloth. This will help boost the efficiency of the air cleaner between full cleaning cycles. This quick clean can be done every time the prefilters are cleaned.

• A full cleaning of the cells will return the air cleaner to its peak efficiency. An easy way to wash the cells is in a tub of hot, soapy water. Just soak the cells until the water cools, agitate and rinse.

Warning: This cleaning procedure requires trained personnel with PPE!

Pressure drop across the air cleaner

Pressure drop is less than or equal to 0.5 in. w.c. (0.1 kPa)?

If pressure drop is more than 0.5 in. w.c. (0.1 kPa), clean the air cleaner immediately.

Is the air cleaner installed downstream from an atomizing humidifier or does the installation include both heating and cooling?

If yes, more frequent replacement may be necessary.

If prefilters are clogged, clean them promptly to avoid restricting airflow and reducing efficiency of the heating-cooling system.

Warning: Ensure the equipment is turned off before starting the replacement process

Is the air cleaner switch turned on and system blower energized?

The neon light next to the On-Off switch is on

The neon light shows that the air cleaner is energized and the high voltage power supply is working correctly

Did you turn off the system blower?

The neon light should go off after a few seconds

Did you 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

If there is a multispeed blower, repeat steps 1 through 3 for each fan speed

Broken or bent ionizer wires can cause an electrical short to ground, often resulting in visible arcing or sparking.

Do not use cells until broken wires are removed.

Cells can be used temporarily with one wire missing, but replace the wire as soon as possible.

Replacement wires are supplied cut to length with eyelets on both ends for easy installation.; To install:

1. Hook the eyelet on one end of the wire over the spring connector on one end of the cell.

Be careful to avoid damaging spring connectors or other parts of the cells.

2. Hold the opposite eyelet with a needle nose pliers and stretch the wire the length of the cell.

Depress the opposite spring connector and hook the eyelet over it.
