1. Locate a suitable place to mount the power unit, under the dock’s roof, within 9 feet of GFCI (Ground Fault Circuit Interrupter) 110-volt outlet. The Ziploc baggy has mounting screws. Mount the unit but do not plug into electrical outlet.

2. Decide on bulb placement location. Bulb should be at least 4 feet below water surface to avoid boat propeller traffic. Locate the supplied weight, slit plastic tube and 2 short zipties.

3. Determine depth of of water, then location where the weight will be attached to cable, keeping in mind the 4’ minimum distance from water surface. Secure weight by placing cable in the slit tube for “rub protection,” then cinch together using 2 zipties. Example: if water depth is 7 feet deep and you need top of bulb 4 feet below water, weight is tied 3 feet from top of bulb.
NOTE: be sure there is no slippage between the cable and weight. If you are in the coastal areas, remember your tide changes!

5. Locate the larger zip ties and use them to secure any slack in the electrical cable.

6. Locate the photocell in the baggy and attach it to the top of the power unit. Gently push the 3 prongs into the unit and turn slightly clockwise to lock. The “eye” window in photocell will point back toward your mounting surface.

7. Plug the GFCI power cord into an approved GFCI outlet. In the late evening the photocell will detect darkness and the light will turn on automatically. It will be dim at first, then gradually becoming brighter in 8-10 minutes.

8. The light will turn off on its own in the morning.
