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: The cleaner does not clean the
entire pool.
Solution: 1. Verify that feed hose reaches within
6 inches 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, see Adjusting
the Wheel RPM 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.
