GETTING THE MOST FROM YOUR ELECTROSTATIC AIR CLEANER
Run the air cleaner as much as possible.
For maximum cleaning efficiency the air cleaner should run all the time. To do this set the fan switch to ON and
make sure the air cleaner is switched ON too. The fan and air cleaner will run even when the furnace or air
conditioner is OFF.
NOTE: The additional cost of running the air cleaner full-time is minimal! The air cleaner actually uses less power
than a 40 watt light bulb! Two cell models - 33 watts; single cell models - 22 watts. The small added cost is more
than offset by the added benefits of full time air cleaning and full time air circulation. In addition, some people feel
that room temperatures stay more even when the fan is always running.
If your fan cannot be controlled independently, you can still obtain maximum available air cleaning benefit. Make
sure the air cleaner is always switched ON so it operates whenever the furnace or air conditioner is on.
Performance Indicator Module
This electrostatic air cleaner is equipped with a special circuit which operates the optional Performance Indicator
Module. This Module is designed to be mounted where it can be easily viewed as it monitors the air cleaner’s
performance.
The three light-emitting diodes (LEDs) on the Module are labelled ON, WASH and CHECK.
The ON LED is lit during normal air cleaner operation.
This indicates that the system fan is also running.
If excessive dirt has accumulated on the air cleaner’s
cell(s), the WASH LED will light to alert you that a cell
and prefilter wash is overdue. (see next section).
A CHECK LED indicates that the air cleaner has
developed a fault. This light usually tells of a fault with
the internal power supply but there are some checks
you can do before calling your service dealer. (see
later section on Service Checks).
