Troubleshooting
The OdorStop UV Air Treatment System is equipped with LED indicator light(s) that verify the unit is
working properly. The OS36 has 1 LED and the OS72 has 2 LEDs.
For OS72: the LED light closest to the on/off switch indicates the status of the UV bulb farthest from the
on/off switch.
Note: The LED light(s) will not shut off when the bulb(s) need replacement. They will only shut off if the
bulb breaks or burns out. The OS72 will operate with one properly functioning bulb. For maximum
effectiveness, both bulbs should be operating properly.
LED lights indicate the following:
• If the LED light(s) is/are green, the UNIT and BULB(s) are functioning properly.
• If one or both LED lights are blinking, the UNIT is faulty and must be replaced.
• If one or both LED lights are not illuminated, the following are possible causes:
• There is no power to the unit - turn on the power supply or plug in the unit.
• The on/off switch is in the “off” position - place switch in “on” position.
• The bulb(s) is/are faulty - replace bulb(s).
• The fuse on the unit is faulty - replace the fuse.
• The LED light has failed - the unit must be replaced.
