Troubleshooting:
Important information: It is a normal characteristic of
all UV lamps to blacken around the filaments (ends) of
the lamp. This does not signify the lamp is defective or
not emitting Ultraviolet light.
The only time a UV lamp is defective is if it will not
light. UV Lamps that illuminate will not qualify for
Warranty.
Check for any loose or disconnected wiring
Lamps are securely plugged into their sockets
Verify the unit has power (120-240 volts) and the
Power switch is in the ON position
The electronic circuit of a 3-lamp system only operates
when all 3 lamps are operating. Unless a lamp is out of
orientation; therefore, make sure the lamps are
plugged in properly.
Verify 5 amp fuse is not blown by performing a
continuity test of the fuse.
NOTE: 24VAC Power supply units do not have
lamp monitoring, please skip to next step.
Verify what signal if any the UV Lamp Monitor LED is
emitting. (See below).
Verify if in fact the UV lamps are on or off. Do not
look at the UV light without proper eye
protection.
Note: A flashing red every 1 seconds and a beep
every 1 seconds does not necessarily mean the
lamps are defective or no longer emitting UV; it is
sensing the lamp(s) in the unit are not on. This could
be caused by other factors.
In this case a service technician should be contacted.
Please contact your local dealer or HVAC contractor
for replacement lamps.
There are NO user serviceable replacement parts
other than the lamps and fuse.
Refer servicing to qualified service personnel.
