Step A Lift black faucet handle up on faucet to start flow of water

through unit. Run 7 gallons of water through unit. Close

faucet.

Note: You may hear some noise as air is being purged from the

unit and the first few glasses of water through the unit may be

dark in color due to carbon fines.
Step B Check for leaks. If you have any leaks, shut off water sup-

ply to system, repair and restart unit.

Step C Connect plastic electrical connector from UV unit to the

plastic electrical connector from AC adapter.

Step D Plug adapter into GFCI electrical outlet. You will see a

pale blue light from the view port on the UV housing

body. The light indicates that the UV lamp is on and

working.

Please follow these guidelines:

Do not unplug UV unit from power supply. Turning system off

and on will shorten the life of the UV lamp. UV should be on

continuously for maximum effectiveness.
The system requires a warm-up period for proper operation.

Wait 20 minutes after plugging in the system before using water.
Water not drawn from unit for a period of time may have a

taste or odor and will be warm. To avoid this, allow water to run

through the system for one minute before using.
