Step 1: Preparing your filtration system
  1. Ensure that pump is switched off
  2. Empty the weir leaf basket
  3. Empty the pump leaf basket
  4. Carry out backwash procedure
Step 2: Identify and replace weir regulator valve

Your weir regulator valve will look similar to:

S21 S22 S23 S24


Replace your weir regulator valve with the CONNECTOR (part GA13):

Step 3: Check Pump Efficiency

Attach one section of hose to the CONNECTOR, and insert the GATORGUAGE, (part no. GA14) into the other end of the hose. Ensure that GATORGUAGE is below water surface. Switch pump on and observe the reading after about 30 seconds.



Step 4: Set GATOR adjustments

S41The GUAGE will register an a, b, c, or d reading. An a reading shows excellent suction and a d reading very poor suction.

S42a or b reading:

Assemble with SPACERS (part GA5)

c reading: Assemble floats without SPACERS

IMPORTANT: A  reading shows an inadequate flow of water and therefore a poorly functioning pump and filter system that needs to be attended to before you can install your GATOR.

S43The TENSION PLATE (part GA2) is set in the factory to medium. It shouldn’t be necessary to change this setting. However, should you wish to experiment, the following is applicable: A higher setting increases the speed of your pool cleaner, and decreases the volume of water entering GATOR. A Low setting will have the opposite effect.

Step 5: Installation

Separate your hose 2 sections from your automatic pool cleaner (3 for deep pools). Take your GATOR and insert the end with the FLOW direction arrow facing toward the weir.

S51 S52

VERY IMPORTANT: installing GATOR in the wrong direction would cause damage to your pump.

S53Allow the GATOR to fill with water by turning on its side, then allow it to float level. Your GATOR is now fully installed! Switch the pool pump on. The GATOR should start operating normally,

and will begin floating randomly over the water surface, removing surface debris as it moves along. Should any problems be encountered, please refer to the “Troubleshooting”

General Maintenance

While the GATOR is designed to reduce pool maintenance time, maintenance of your entire pool system should be completed for optimum GATOR performance.

Important:  Switch the pool pump off before carrying out cleaning procedures.

  1. Empty leaf baskets frequently
  2. Backwash the filter regularly.
  3. Check the GATOR for: a) leaves trapped in the flap valve area and b) easy

movement of inner and outer cylinders.

  1. Periodically use the GATORGUAGE to ensure that no leaks or faults have

developed in your pump/ filter system.

  1. Problem: GATOR is sluggish or does not operate at all.Solution: 1. Check that CONNECTOR is substituted for your weir regulator valve.
    1. Check that weir and pump baskets are clean.
    2. Backwash the filter.
    3. Check that vacuum lid is flush in the weir.
    4. Check that water flow direction through GATOR is correct.
    5. Check that aim flow(s) is not restricting return water flow.

    (E.g. a wall mounted leaf skimmer would create this problem).

    1. Increase the tension on the TENSION PLATE on GATOR.

    Problem: Surface water enters GATOR too slowly.

    Solution: 1. Refer to items 1—4 above.

    1. Decrease the tension on TENSION PLATE on GATOR.
    2. Add an extra float spacer to each side.

    Problem: GATOR rises up out of the water and takes in air.

    Solution: 1. Increase the tension on TENSION PLATE.

    1. Add one float spacer to each side.
    2. Check that inner and outer cylinders move easily in relation to

    each other. If not, remove the slide stop rivet (part no. GA8),

    separate the cylinders, rinse off any debris and reassemble.

    Problem: Automatic Pool cleaner hose curls up or tangles around GATOR.

    Solution: 1. Move GATOR 1 or 2 hose sections closer to the pool pump.

    1. Ensure that hoses are not twisted when attaching GATOR.

    Problem: Automatic Pool Cleaner moves in a fixed pattern.

    Solution: 1. Adjust the return outlet (airflow) towards the bottom of the pool.

    1. Ensure that hose lengths are in good condition
    2. Pool hose may be too short. Add more lengths of hose.
    3.   Consult your automatic pool cleaner instruction manual.
