WIRING OPTION 1
The multivoltage ballast is self-adjusting and operates with voltages from 120 - 240 VAC. This unit must
cycle with the furnace blower. Install provided 120 VAC power cord and plug the unit into a 120 VAC outlet
which is interlocked with the furnace blower. If an EAC terminal is available, supply power to the outlet from
the EAC terminal. Connect in accordance with local wiring codes. If there is no EAC terminal, interlock the UV
unit with the furnace blower using an appropriate alternate. After installing verify voltage is operating between
120 - 240 VAC with air handler operating. For 240VAC wiring install 5 amp inline fuses and use optional 240
VAC power cord, Part #PC-240.
WIRING OPTION 2
For hard wiring to 240V systems install 5 amp inline fuses to both legs of power. Then connect the black wire to
L1, white wire to L2, green wire to ground. For 120V wiring install a 5 amp fuse to L1 connect the black wire to
L1, white wire to neutral, green wire to ground. Be sure power cord is secured with a strain relief connector.
Wire the unit in accordance with local wiring codes. After installing, verify voltage is operating between 120
- 240 VAC with air handler operating. Optional power cord with pig tails is available along with a strain relief
connector for hard wiring. Part number PC-HW
