UV LAMP REPLACEMENT
This furnace series comes equipped with an ultraviolet lamp located on the
right side of the heat exchanger. This unit helps to reduce the number of
bacteria within the household and also helps to clear the "A" coil for your
air conditioning system of mold and germs, increasing its effi ciency and
reducing electrical consumption.
The supplied bulbs have an approximate operating life of 9,000 hours
(approximately one year with continuous fan). In order to remain effective,
this bulb must be replaced at the appropriate interval. Instructions to do so
are as follows:
1. Switch off power to the furnace.
2. Remove the bottom door of the furnace.
3. Using 1/4" socket driver, remove the single mounting screw that retains the lamp bracket to the blower
division. The bulb unit can now be removed from the furnace. Be careful not to break the existing bulb
when removing it through the blower division.
