SYSTEM CHECKOUT
WARNING:
The following procedures should be conducted by a
qualified HVAC contractor or repair person ONLY. These procedures
will expose hazardous electrically energized charged components.
Disconnect power between checks and proceed carefully.
1. The HVAC system blower should be turned OFF.
2. Switch the ON/OFF rocker switch to the ON position. The bright red
segment of the rocker switch should be visible.
3. Inspect both the Green INPUT POWER light and the Red CELL
ENERGIZED light:
• If the unit has an AFS installed, the lights should go out in
approximately 20 to 60 seconds. This is the normal time for the
electronic air flow sensor to complete its stabilization period. Both
lights will come back on when the HVAC system blower begins to
operate. See the section entitled
for more information
• If the unit is wired directly to the HVAC system blower, the lights will not
come on until the blower begins to operate. In this case, the electronic
air cleaner will stay on as long as the ON/OFF switch is in the ON
position and the blower is operating.
• If the unit is wired directly to a dedicated 120V power source, the lights
will come on immediately and stay on for as long as the ON/OFF
switch is in the ON position, regardless of the HVAC system blower
operation. This type of installation is NOT recommended due to the
excessive production of ozone. See the section entitled
for more information.
4. Wait approximately one (1) minute and turn the HVAC system blower
ON. Most thermostats have a setting that will allow you to run the fan
manually. If not, then set the thermostat so that either hot or cold air
begins to flow through the ductwork.
5. The Green INPUT POWER light and Red CELL ENERGIZED light should
come on, if the unit is wired directly to a dedicated 120V power source,
the lights will already be on and will not be affected by the HVAC system
blower operation (see Step 3).
6. Check to make sure that the Red CELL ENERGIZED light goes out when
the following conditions occur:
• Cell access panel is removed
• Rocker switch is switched to the OFF position
• HVAC system blower is not running.
