OPERATION

The exclusive Aprilaire Air Cleaner Control (see Figure 3) is installed by your contractor at a location that is convenient for you. It may be located next to your thermostat, on the air cleaner or near your heating and cooling equipment.

1Filtering

When the air cleaner is cleaning the air, either at your command or when the heating and cooling system is operating, bars on the display will sequence on and off to let you know that it is working

2Filter Life Indicator

This area of the display indicates filter usage. Bars will build indicating usage increments of 20%, based on how the Air Cleaner Control was set up. When all bars are filled and begin to flash, it is time to change the filter. See the Maintenance section on page 5 for more details.

3Active Cleaning

Four selections are available to choose the Air Cleaner Control option that is best for you, beyond the cleaning that occurs whenever your equipment is heating or cooling.

ACTIVE CLEANING OPTIONS

To select any of the options below, simply press the corresponding button, and an arrow will appear next to the button indicating which option has been selected. To cancel a selection, simply press the button again.

Constant Cleaning:

This option will provide the maximum amount of air cleaning available. The air cleaner will be active for 24 hours a day, seven days a week.

Automatic (30 min./hr):

The air cleaner will run a minimum of 30 minutes every hour. The Air Cleaner Conrol will monitor the amount of time your heating and cooling system runs; if 30 minutes is not reached the Air Cleaner Control will automatically turn on the air cleaner. This will maximize the amount of air cleaning while minimizing energy consumption.

Event Clean (3 hour cycle):

When selected, the air cleaner will run for 3 hours continuously and then turn off. This option only cleans the air when needed; an example would be after vacuuming.

Allergies (24 hour cycle):

When seasonal allergies spike and outside air quality is at its worst, choose this option to run your air cleaner continuously for 24 hours then turn off.
