Head adjustment and functions.

A. Thrust Jet:
B. Sweep Hose Adjustment Screw: Regulates water flow to the sweep hose; the recommended setting is adjusted to provide a gentle sweeping motion. The sweep hose reomves debris from the corners and steps. Tighting the screw decreases the sweeping motion and vise versa.
C. Head Float: Affects the ballast of the cleaner: the recommended setting is all the way forward. Moving the head float forward (toward the cleaner) improves climbing ability and vise versa.


Thrust Jet.

Thrust Jet: Acts as a steering mechanism; the recommended setting is 11 o'clock. Moving the thrust jet to the left will turn the cleaner left and vice versa. Setting the thrust jet between 11:00 and 1:00 will provide maximum climbing ability.


Check RPM of the wheels.

RPM Check
  1. Mark the single-side wheel.
  2. Turn on the filtration and booster pumps, and allow the back-up valve to complete a back-up cycle.
  3. Hold the cleaner completely under the water and count the wheel revolutions for one minute.
  4. RPM range needs to be between 28-32.

Problem:
Hangs up on steps or other obstacles longer than 3 minutes.
Solution:
Polaris Sweep Hose Spraying House
  1. Check RPM of the wheels.
  2. Verify the back-up valve (54) is cycling. Hold the valve out of the water and watch the jet. It should come on and go off. If not - replace it.
  3. Adjust the thrust jet (21).
  4. Remove unnecessary pool hardware or install a Ladder Guard Kit (order part #G21).
  5. With the Polaris turned off, spin each of the wheels. All wheels should turn together. If not, replace the Drive Belt (8)

Problem:
Sweep hose is sucked into the vacuum tube.
Solution:
Polaris Cleaner Sucked Tail
  1. Make sure the opening at the end of the sweep hose is not blocked by the sweep hose scrubber.
  2. Adjust the sweep hose at the Sweep Hose Adjustment Screw (23) to a gentle sweeping motion.

Action:
Polaris is sluggish, running with less power than normal.
Solution:
  1. With the Polaris turned off, spin each of the wheels. All wheels should turn together. If not, replace the Drive Belt (8)
  2. Check the filter screen (44) in the Quick Disconnect (41) and clean if necessary.
  3. Clean the skimmer basket, pump basket, and pool filter.
  4. Check the hoses, connections, and swivels (50) for leaks that could cause loss of water pressure.
  5. Check the wheel RPM.

Action:
Sweep hose sprays too much water out of the pool.
Solution:
Polaris Sweep Hose Spraying House
  1. Adjust the speed of the sweep hose by tightening the adjustment screw (23).
  2. Replace the sweep hose scrubber if it is worn or missing.
  3. Add a sweep hose weight to keep the sweep hose from spraying.
  4. Check the wheel RPM. If more than 32 RPM, unscrew the pressure relief valve (46) to decrease water flow to cleaner.

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 (52).
  2. Check the thrust jet (21) for 11:00 position that optimizes random turning.
  3. While the cleaner is operating, hold it upside down and look into the vacuum tube. There should be three distinct, even jets of water. If there are not, replace the Water Management System (28)
  4. With the Polaris turned off, spin each of the wheels. All wheels should turn together. If not, replace the Drive Belt (8)

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 32 RPM, unscrew the pressure relief valve (46) to decrease water flow to cleaner.
  2. Confirm that the blue restrictor disc (40) is installed in the UWF to decrease water flow. Or, install the red restrictor disc (40) to decrease the water flow even more.
  3. Verify the back-up valve (54) is cycling. Hold the valve out of the water and watch the jet. It should come on and go off. If not - replace it.

Action:
The cleaner is running in circles on its side.
Solution:
my polaris runs on its side
  1. Check the filter bag, if full it can weigh the cleaner down on one side.
  2. Remove the head float (35) and shake it. If there is water in the float, order a new one.
  3. Check the hose floats (51) to make sure they are spaced evenly.
  4. With the Polaris turned off, spin each of the wheels. All wheels should turn together. If not, replace the Drive Belt (8)

Action:
Polaris doesn't back up.
Solution:
  1. Verify the back-up valve (54) is cycling. Hold the valve out of the water and watch the jet. It should come on and go off. If not - replace it.
  2. Check the wheel RPM.
  3. If the filter bag is full, empty or replace it.
  4. Make sure feed hose (52) is floating.

Action:
Polaris only turns in one direction.
Solution:
  1. Check the thrust jet (21) for 11:00 position that optimizes random turning.
  2. Make sure feed hose (52) is floating.
  3. With the Polaris turned off, spin each of the wheels. All wheels should turn together. If not, replace the Drive Belt (8)

Action:
Feed hose becomes tangled.
Solution:
tangled polaris hose
  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 (50) in the hose and the hose connections turn freely.
  3. Make sure the feed hose is floating.
  4. With the Polaris turned off, spin each of the wheels. All wheels should turn together. If not, replace the Drive Belt (8)
