non-electrical end cap by hand. Install the other O-ring over the open end of
the sleeve on the chamber end that has the grounding screw attached –
hand-tighten. Once assembled, tighten ¼-1/2 turn using a wrench or pliers, do
not over-tighten.
8. Remove the lamp from its protective packaging. Clean lamp exterior with a
clean cloth. Be careful not to leave fingerprints on the lamp. Connect the 4-
pin electrical connector to the pins on the UV lamp. Insert the lamp through
the opening at the end of the electrical end cap until the connector is inside
the end cap.
9. Loosen the setscrew on the side of the lamp plug cover, and place the cover
over the ledge of the electrical end cap. Tighten the setscrew.
10. Remove the nut on the grounding stud and place the grounding wire (green &
yellow) onto the stud. Replace the nut and tighten.
11. Ensure the valves on either side of the disinfection unit are closed. Open the
main supply valve. Open the valve on the discharge side of the disinfection
unit. Open the valve slowly on the feed side of the disinfection unit. Check for
leaks. If any leaks are present, close valves and repair.
12. Connect UV power source to a 120v receptacle. A green Lamp-On LED light
indicates the lamp is ignited and a 365 Lamp Life Days countdown is
displayed on the screen (for model before February 2011, the UV power
source audible alarm will sound 3 times before igniting the lamp, Lamp Life
Days countdown display is not available).
13. Your Excelight UV Disinfection System is now ready for use.
Before service
begins all household plumbing lines should be disinfected.
14. Momentarily operate the unit with the lamp disconnected to allow you to
validate the adequacy of the audible alarm function in your installation. You
should be able to hear it from other parts of the house, so that you will be
easily alerted in the event of lamp failure.
