SECTION I. NORMAL OPERATION.
Water passes over the weir, through the basket and equalizer assembly, and then to the pump. The trimmer in the

equalizer or the trimmer on the bottom of the skimmer are both open.

W ARNING

Keep the skimmer lid properly secured at all times. Failure to keep the lid secured can cause the lid to become dislodged
when stepped on, resulting in risk of serious injury.

WARNING

Replace the skimmer lid if it is worn or damaged. Failure to replace a worn or damaged skimmer lid can cause the lid to
break when stepped on, resulting in risk of serious injury.

SECTION II. CLEANING.
Skimming the surface of the pool is very important for overall pool cleanliness. The filter keeps your pool clean. If

debris, i.e. leaves, insects and dirt, is collected before it reaches the filtering system the filter is not as likely to become
overloaded. Skimmer baskets should be checked and emptied at least once a week - once a day if it is especially windy

- because debris left in the basket too long deteriorates and eventually goes into the filter. The purpose of the skimmer is
to save the pool owner from having to manually skim the pool every day.

To remove the skimmer lid, insert your index finger into the slots in the skimmer lid and press the tabs toward the center
of the lid, while lifting the lid, see Figure 1.

SECTION III. ADJUSTING THE SKIMMER
FLOW.

If the skimmer flow is too fast, due to excessive flow
rate, rotate the equalizer trimmer to partially cover the
equalizer assembly hole until the desired skimmer flow
is obtained.

To brush the pool, when the skimmer is plumbed to
the main drain, close the equalizer assembly hole with
the equalizer trimmer. If the skimmer does not have an
equalizer assembly, rotate the trimmer in the skimmer
over the suction port until the desired flow is obtained.

SECTION IV. MULTIPLE SKIMMERS.
Rotate the skimmer trimmer over the pump port to restrict the flow from the skimmer. This will balance the flow from

any number of skimmers.
SECTION V. LOW WATER LEVEL (FOR MODELS WITH EQUALIZERS).

Figure 1.

When the water level drops below the weir, the pump will lower the water level in the skimmer to the equalizer float, in
the equalizer assembly. The upper portion of the skimmer will then shut off and permit the water to flow from the
equalizer line directly to the pump.

NOTE

A simular action occurs when and if the basket is plugged with leaves and debris.
