3. Remove any conductive connections from inside the pool to ground. This
includes ladders, thermometers, vacuum poles leaning up against the coping,
or wet pool covers that extend from the water to the ground. If you cannot re-
move ladders, a plastic trash bag can be put over the ladder, effectively
insulating it from the pool water.
4. Cover any lights with the light cover provided. Place the cover over the light
with the rubber gasket against the pool wall and the hose connections at the
bottom. Keep the two hoses above water level. To get the cover to make an
initial seal you may need to trap some air in the cover. This is done the same
way a diving mask is cleared, by holding the top of the cover against the pool
wall and blowing through the hose without the pump. Once a seal is made
pump some of the water out of the inside of the light cover with the hand
pump. One or two pumps should be enough to get the cover to stay. Howev-
er, you may wish to pump all of the water out to provide a better seal and
more effective electrical insulation of the light. The hoses must be left above
water level, but not plugged, for proper seal. The cover can be removed by
placing the hose without the pump into the water below the bottom edge of
the cover.
Warning: This light cover is not intended for any use where the
rubber inner tube gasket contacts the vinyl pool wall for over 2
hours. Oils in some vinyl liners may attack the rubber gasket causing
permanent discoloration to the liner. If extended use is required,
cut a piece of scrap vinyl to put between the pool wall and gasket.
5. Depending on the pool, fitting screws (especially at skimmers and main
drains) can be connections to ground which create confusing Leak Track
signals. With experience you will learn to disregard these signals (you should
have also already dye tested these areas, eliminating them as a potential
leak). Simple methods of covering the fittings can be used if elimination of the
signal is preferred. Skimmer and return fitting screws can be covered with
small suction cups (used for hanging signs on windows). The main drain can
be covered using the Light Cover modified with longer hoses. An attachment
that allows the Light Cover to be positioned over the main drain using your
telescoping pole is available from Anderson Mfg. Co.
Note: In most cases plugging return fittings and main drains to eliminate
connections back to the grounded equipment is unnecessary. Instead of
eliminating these connections, it is possible to disregard the relatively
weak “Leak Track” signal they produce.
