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), stop the procedure and report to the maintenance team

Is the air cleaner installed downstream from an atomizing humidifier?

Does the installation include both heating and cooling?

If either of the above is true, more frequent replacement may be necessary.

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

Always disconnect power and open access door before opening power supply cover.

The electronic air cleaner generates a small amount of ozone in normal operation.

During the first week or two of operation, the amount may be higher because of sharp edges on some of the new high voltage metal parts.

Normal use quickly dulls these edges.

If desired, the ozone generated by the air cleaner can be reduced in one of two ways:

1. Install an activated carbon filter downstream from the air cleaner. Make sure particles from the air filter cannot fall into the air cleaner.

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.
