Air Cleaner Control Installation Instructions
Fits Models 2120, 2140, 2200, 2400 & 5000
The electronic controls (Figure 1) are used to circulate air through the air cleaner, monitor filter life and
inform the user that the air is being cleaned. Users can turn on the blower for a set period of time or
adjust it so that the blower is on, either as part of a heating/cooling call or blower only, for a set number
of minutes per hour. This requires the Air Cleaner Control to be mounted in an accessible location, and
requires 18-22 gauge (standard thermostat cable) wires to be run between the air cleaner components
and the HVAC components.
THE AIR CLEANER CONTROL CAN BE MOUNTED:
• Option 1 (see below): near the thermostat.
• Option 2 (see opposite side): on the air cleaner in the LED Base.
• Option 3 (see opposite side): near the HVAC equipment.

1
Run a 3-conductor cable between the LED Base and the low
voltage controls of the HVAC equipment.
2
Remove the cover from the LED Base and wire the LED Base to
the low voltage controls of the HVAC equipment as shown in
Diagram 3. Replace the cover on the LED Base.
3
Remove the backplate from the Air Cleaner Control and install
the backplate near the thermostat. Use the wire opening in the
wall behind the thermostat to make sure there is not a wall
stud between the thermostat and desired mounting location.
4
Run a 5-conductor cable between
the thermostat and Air Cleaner
Control.
5
Wire the thermostat to the
Air Cleaner Control as shown
in Diagram 4 or Diagram 5.
Diagram 4 is for standard, single
transformer systems; Diagram
5 is for two-transformer systems
such as radiant heat with forced
air cooling. Replace the Air
Cleaner Control on the backplate.

Position the LED Base on the top of the Air Cleaner. If you have a plastic door latch on the top of the
Air Cleaner position the LED Base right behind the latch (see Diagram 1).
If you don’t have a plastic door latch on the top of the Air Cleaner position the LED Base close to the
front edge (see Diagram 2).
Note: Leave 4-1/2” above LED Base to allow for installation of the Air Cleaner Control to LED Base.
INSTALL THE AIR CLEANER CONTROL BASE

LED BASE MOUNTING STEPS:
1. Remove filter assembly from Air Cleaner.
2. Position LED Base on top of Air Cleaner centered as shown in Diagrams 1 & 2.
3. Remove cover from LED Base.
4. Mark the two mounting hole locations and drill 1/8” diameter holes.
5. Assemble the LED Base to the Air Cleaner with screws provided.
6. Replace the cover on the LED Base.
