TROUBLE-SHOOTING
AIR PURIFIER WILL NOT START - NO FAN OR LIGHTS
TRACS utilizes a differential pressure switch that shuts off the power to the unit when
the particulate buildup gets so high the carbon pre-filter or HEPA filter need to be
replaced. This function is key to ensure that the unit is not operated too long with
clogged filters, because doing so could do serious damage to the blower, as the motor
would not receive enough air.
Therefore, when the indicator light on the control panel illuminates, it means that the
carbon filter and or the HEPA filter need to be replaced. The carbon filters should be
replaced every 3-6 months and the HEPA filter can last up to 5 years in a residential
environment (2 years in commercial applications).
If your air purifier will not start and no lights
are lit, you may also try the back panel
access door emergency cutoff switch. It is
located underneath the unit. Please do not
bypass this switch with the access panel
removed. If this switch is not activated, the
unit will not start. Ensure proper contact is
made between the door panel and micro-
switch.
Control Panel Lights
When the yellow HEPA filter warning light is energized, you should replace the HEPA
filter asap. We have installed a differential pressure switch which measures the airflow
through the HEPA. Continued operation of the TRACS air purifier with this light
energized could result in overheating of the fan motor.
The two green LEDs labeled UV1 and UV2 monitor the function of the lamps inside your
TRACS unit. During normal operation these LEDs should be illuminated. This means
the UV lamps in the unit are on and operating at peak efficiency. UV1 is the lamp on
the right looking into the unit from the back and UV2 is on the left. When a UV lamp
needs to be changed, the corresponding LED will go out or flicker.
