16. For air treatment systems, wait ten minutes for the 

airflow sensor to calibrate. During this time, the furnace 

fan must remain off.

NOTE: Failure to wait ten minutes for the airflow sensor to 

calibrate before powering the furnace causes the 

airflow sensor to incorrectly calibrate and the device 

to incorrectly function. If this occurs, remove power to 

the furnace or turn off the system and fan, wait ten 

minutes, and then resume normal furnace operation.

17. Reconnect the power to the HVAC system.

18. Choose a location on the adjacent HVAC equipment for 

the HVAC maintenance UV warning label included in the 

UV system packing box. Choose a location that a future 

installer can easily see during any future HVAC 

maintenance or repair.

19. Adhere the HVAC maintenance UV warning label to the 

HVAC equipment (selected in step 17) such as the 

furnace, air cleaner or humidifier. See Fig. 8.

The installer should verify that the ultraviolet bulb(s) are 

operating only by viewing the lamp light indicator on the lamp 

handle. Do not attempt to look directly into the duct to see the 

illuminated ultraviolet bulbs. See Fig. 9.

The installer should orient the homeowner to the unit by 

showing them the blue glow of the lamp light indicator and 

discussing how to determine when the unit is functioning 

properly without looking directly into the duct to see the 

illuminated ultraviolet lamp. The installer should also 

emphasize the hot surface and electrical shock safety 

warnings.

The installer should show the homeowner the LED on the front 

of the UV system and explain operation as follows:

 a

Bulb life means emitting adequate amount of UV-C energy to 

maintain an effective kill rate. At 0% bulb life remaining, the 

lamp continues to operate until catastrophic bulb failure (bulb 

burns out) but the kill rate becomes rapidly negligible.

Installer should also orient the homeowner to the reset button 

on the bottom of the UV system that, when pressed briefly for 

one second, can be used to command lamp on for the 

minimum run time of 40 minutes (air treatment system) or three 

hours (surface treatment system), depending on system type. 

And that when a new bulb is installed, the homeowner must 

hold the reset button for five seconds to reset the internal 

timers. Cycling power does not reset internal timers.

When using Enviracom communication bus to communicate 

with other appliances, the installer should orient the home-

owner to the Enviracom LED and three screw terminals. The 

Enviracom LED flashes when transmitting and lights solidly 

when there is a fault. 

The installer should also explain the extended-bulb life for the 

surface treatment system. For the single-lamp and dual-lamp 

air treatment systems, the installer should orient the home-

owner to the alternate method of using the UV system to 

monitor the thermostat load information to turn lamp off and on 

instead of using the air flow sensor to control lamp operation 

and that it communicates the percent remaining bulb life.

The installer should leave the Owner’s Guide with the 

homeowner and review the bulb cleaning and replacement 

procedures. A Bulb Cleaning Reminder Schedule is included in 

the Owner’s Guide to help the homeowner set up and track a 

regular cleaning schedule.
