Troubleshooting

If the Polaris cleaner regularly displays the following actions, adjustments may be necessary to restore performance. Refer to exploded parts diagram for part references.

Action: Hangs up on steps or other obstacles longer than

3 minutes.

Solution: 1. Check the wheel RPM.

2.Verify the back-up valve is cycling.

3.Adjust the thrust jet.

4.Remove unnecessary pool hardware or install a Ladder Guard Kit (order part #G21 from a Polaris dealer).

Action: Polaris is sluggish, running with less power than normal.

Solution: 1. Check the filter screen in the in-line filter assembly and clean if necessary.

2.Clean the skimmer basket, pump basket, and pool filter.

3.Check the hoses, connections, and swivels for leaks that could cause loss of water pressure.

4.Check the wheel RPM.

Action: Polaris flies around the pool and/or does not make contact with the bottom of the pool.

Solution: 1. Check the wheel RPM. If more than 36 RPM, unscrew the pressure relief valve

to decrease water flow to cleaner.

2.Install the blue restrictor disk in the UWF to decrease water flow. Or, install the red restrictor disk to decrease the water flow even more.

3.Verify the back-up valve is cycling. Hold the valve out of the water and watch the jet. It should come on and go off.

Action: Polaris doesn’t back up.

Solution: 1. Verify the back-up valve

is cycling.

2.Check the wheel RPM.

3.If the filter bag is full, empty or replace it.

4.Make sure feed hose is floating.

Action: Polaris only turns in one direction.

Solution: 1. Adjust the thrust jet.

2.Make sure feed hose is floating.

Action: Feed hose becomes tangled.

Solution: 1. Remeasure the hose to verify that it is adjusted to the proper length for the pool shape.

2.With the Polaris operating, check that the swivels in the hose and the hose connections turn freely.

3.Make sure the feed hose is floating.

4.With the Polaris operating, hold the cleaner under water and verify that all three wheels are turning together.

Action: Sweep hose is sucked into the vacuum tube.

Solution: 1. Make sure the opening at the end of the sweep hose is not blocked by the sweep hose scrubber. Replace scrubber if it is worn

or missing.

2.Adjust the sweep hose to a gentle sweeping motion.

3.Check the wheel RPM. If more than 36 RPM, unscrew the pressure relief valve to decrease water flow to

the cleaner.
