WARNING: USE OF POLARIS ATV IN A VINYL LINER POOL
Certain vinyl liner patterns are particularly susceptible to rapid surface wear or pattern removal
caused by objects coming into contact with the vinyl surface, including pool brushes, pool toys,
floats, fountains, chlorine dispensers, and automatic pool cleaners. Some vinyl liner patterns can
be seriously scratched or abraded simply by rubbing the surface with a pool brush. Ink from the
pattern can also rub off during the installation process or when it comes into contact with objects
in the pool. Zodiac Pool Systems, Inc. is not responsible for, and the Limited Warranty does not
cover, pattern removal, abrasion or markings on vinyl liners.

2. Adjust Feed Hose To Fit Pool Length
Measure the deepest part of the pool. Cut leader hose, from end that attaches to feed1.
hose, so length is equal to the greatest depth of the pool.
Attach leader hose to feed hose and connect hose to the pool wall at the return line.2.
Extend hose to farthest point of pool. The hose end must be within 6” – longer or shorter –
of the farthest point. See diagram below.
If hose is too long:Separate hose at center swivel. Cut equal amounts of the overage
from each 10-foot feed hose section.
If hose is too short: Add a feed hose section (part #9-100-3104), a swivel (part #D20)
and two hose nuts (part #D15). Adjust to proper length.
Each feed hose section should be equal in length after adjustments.
After adjusting the length, position the hose floats as shown.3.

4. Check for Proper RPM
Before operating the Polaris®, check
for proper wheel revolutions per minute
(RPM).
For maximum efficiency, the cleaner
should operate between 30 and 36 RPM.
Mark the single-wheel side tire.1.
Turn pump on, hold cleaner below2.
water level and count wheel
revolutions for one minute.
If count is not in target range, refer
to Adjusting the Wheel RPM in the
Troubleshooting section for more
information.
Single-wheel Side
Sweep Hose

FINE TUNING THE CLEANER
When operating correctly, the cleaner vacuums, sweeps and scrubs all surfaces randomly
throughout the pool. Approximately every three minutes the cleaner goes into back-up mode.
This action pulls the cleaner away from pool obstacles and increases its random pattern.
Thrust Jet Adjustment
The thrust jet powers the
direction of the cleaner.
Factory position is seven
o’clock but, depending on
the pool, other settings
can be helpful to improve
cleaner coverage.
Sweep Hose Adjustment
The sweep hose should move
in a gentle sweeping motion.
To adjust the motion, turn off
the booster pump and turn
the sweep jet clockwise to
increase or counter-clockwise
to decrease the movement.

Empty the filter bag when it is
half full, especially if the debris
load is sand.
It is easier to empty the filter bag
when it is dry. Alternate between
two bags.

Cleaning the Filters
Always disconnect the Polaris® before
cleaning or backwashing the pool filter,
and let the filtration system run for at
least five minutes before re-connecting
the cleaner.
To clean the in-line filter screen, pull it
out of the filter assembly, rinse it and
press it firmly back into place.
Storage and Winterising
Never store the cleaner in direct sunlight.
When storing for the winter, drain all the water from the cleaner (freeze

remove the UWF from the pool wall. If necessary, use the UWF Removal
Tool (part #10-102-00) available from any authorized Polaris® dealer.

TROUBLESHOOTING
If the cleaner regularly displays any of the following actions, adjustments may be necessary to
restore performance. Refer to the exploded parts diagram for part references.
Action: Cleaner hangs up on steps or other obstacles for longer than 3 minutes.
Solution: 1. Check the wheel RPM.
2. Verify the back-up valve is cycling. Lift the valve out of the water and watch
the jet. It should come on and go off.
3. Adjust the thrust jet.
4. Remove unnecessary pool hardware or install a Ladder Guard Kit
(part #G21).
Action: Cleaner 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, hose connections, and swivels for leaks that could cause
loss of water pressure.
4. Check the wheel RPM. If below 30 RPM, see Adjusting the Wheel RPM to
increase flow to cleaner.
Action: Cleaner races around the pool and/or does not make contact with the pool
bottom.
Solution: 1. Check the wheel RPM. If more than 36 RPM, see Adjusting the Wheel RPM
to reduce flow.
2. Verify the back-up valve is cycling. Lift the valve out of the water and watch
the jet. It should come on and go off.
Action: Cleaner doesn’t back up.
Solution: 1. Verify the back-up valve is cycling. Lift the valve out of the water and watch
the jet. It should come on and go off.
2. Check the wheel RPM. If not in 30-36 RPM range, see Adjusting the Wheel
RPM.
3. If the filter bag is full, empty or replace it.
4. Make sure feed hose is floating.
Action: Cleaner 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.
2. With the cleaner operating, check that the swivels and 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: The front end of the cleaner lifts all the time.
Solution: 1. Check the wheel RPM. If not in 30-36 RPM range, see Adjusting the Wheel
RPM.
2. Adjust the thrust jet downward.
3. Verify the back-up valve is cycling. Lift the valve out ofthe water and watch the
jet. It should come on and go off.
4. Check for water inside the cleaner float.
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, see Adjusting the Wheel RPM
to reduce flow.
4. Add a sweep hose weight (part #B2).
Action: Sweep hose sprays too much water out of the pool.
Solution: 1. Adjust the speed of the sweep hose.
2. Pull the sweep hose scrubber down to cover more of the tip of the hose.
3. Replace the scrubber if it is worn or missing.
4. Add a sweep hose weight (part #B2).
Action: The cleaner does not clean the entire pool.
Solution: 1. Verify that feed hose reaches within 6” of the farthest point of the pool. If not,
order a new hose section from your Polaris® dealer.
2. Adjust thrust jet to improve coverage.
Action: The cleaner is running in circles on its side.
Solution: 1. Check for water inside the cleaner float.
2. Check the filter bag, if full it can weigh the cleaner down on one side.
3. Check the hose floats to make sure they are spaced evenly.
4. Check the wheel RPM. If more than 36 RPM, make adjustments to reduce
flow.

Adjusting the wheel RPM:
If count is less than 30 RPM:
If an adjustable valve is installed on the cleaner line, open it completely so water can flow•
freely to the Polaris®.
Check the filter screen in the in-line filter for debris that restricts water flow.•
Clean the skimmer, filter and pump basket, clearing debris that restricts water flow.•
Check the hoses, connections and swivels for leaks that cause loss of water pressure.•
Remove the blue restrictor disk from the UWF.•
If count is more than 36 RPM:
Replace the blue restrictor disk in the UWF with the red restrictor. If the flow is still too•
high, unscrew the pressure relief valve until the proper RPM is reached. Note: The
pressure relief valve should only be adjusted when a restrictor is installed.
If an adjustable valve is installed on the cleaner line, adjust it to reduce the water flow to•
the cleaner.
