UV100E ULTRAVIOLET SYSTEMS
68-0262—09 8
TROUBLESHOOTING AND SERVICE
The Ultraviolet System has no field-serviceable parts. Bulb
cleaning is recommended as routine maintenance
quarterly or every three months. Bulb replacement is
required when the LED on the front of the UV system is
lighted solidly. See the Owner’s Guide for detailed
procedural information.
If systems with an airflow sensor (UV100E1043 and
UV100E2009 Air Treatment Systems), incorrectly identify
airflow, the airflow sensor may be calibrated incorrectly. To
recalibrate the sensor, remove power to the furnace or turn
off the system and fan, wait ten minutes, and then resume
normal furnace operation. Even if the lamp fails to turn off,
the sensor was recalibrated during this operation.
If the internal temperature exceeds the ballast high-
temperature limit, the control continues to retry every
three hours until the temperature is low enough to run
correctly. An Enviracom fault message (when connected)
sent after 72 hours. If reset is pushed during this fault, the
control tries to restart but cannot start until temperature
returns to normal.
If the bulb(s) burns out, experiences low supply voltage
(brownout) or has an internal catastrophic failure, the
control continues to retry once every hour until the
problem is corrected. An Enviracom fault message (when
connected) is sent after 24 hours. If reset is pushed during
this fault, the control tries to restart but cannot start until
fault is corrected.
To determine if a bulb is burned out or other problem
exists, press the reset button briefly (one second). The
bulb(s) should come on (as indicated by the illuminating
lamp light indicator). Hold reset button longer only when
replacing the bulb.
