CAUTION: USE OF THE POLARIS 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 0r markings on vinyl liners.

Congratulations on the purchase of your new automatic pool cleaner, and thank you for
choosing Polaris. The Polaris 3900 Sport/P39 is designed to give you years of dependable
and efficient service.
Like most mechanical devices, it will require periodic adjustments, routine maintenance, and
the replacement of certain hardworking parts. Please have the cleaner checked occasionally
by your local Polaris dealer or service center.
Always insist on genuine Polaris replacement parts. Non-Polaris parts are not made to our
specifications. They may have an adverse effect on the operation of your Polaris or may even
damage it.
For best results, the cleaner should be installed by a pool professional. Forthose with
experience and confidence in handling plumbing and mechanical equipment, installation is
outlined in this manual.

Adjust Feed Hose To Fit Pool Length
1. Measure the deepest part of the pool. Cut leader hose from the end that attaches to the
feed hose (away from the back up valve) so length is equal to the greatest depth of the
pool.
2. Attach leader hose to feed hose and connect hose to the pool wall at the return line.
Extend hose to farthest point of pool. The hose end must be within 6 inches — longer or
shorter— of the farthest point. See diagram below.
If hose is too long: Separate hose at center swivel. Cut half ofthe overage from each
10-foot feed hose section that attaches to the center swivel.
If hose is too short: Add a feed hose section (part #9-100-3104), a swivel (part #D20)
and two (2) hose nuts (part #D15). Adjust to proper length.
Each feed hose section should be equal in length after adjustments.
3. After adjusting the length, position the hose floats as shown.
ACAUTION
Use caution when cutting the hose to prevent injury inflicted by the cutting tool.

Assemble the Cleaner
1. Attach the feed hose connector
to the feed pipe by pressing it
down firmly until it looks.

Connector
3. Turn on the pool filtration
pump and allow it to prime
before turning on the booster
pump. (Referto booster pump
manufacturer’s instructions for
booster pump priming time.)
Check for Proper RPM
Before operating the Polaris, check
for proper whee| revolutions per
minute (RPM).
For maximum efficiency, the cleaner
should operate between 30 and 36
RPM.
SingIe-wheel Side
1. Mark the singIe-wheel
side tire.
2. Turn pump on, hold cleaner
be|ow water level and count
whee| revolutions for one minute.
Sweep Hose
If count is not in target range,
refer to Adjusting the Wheel
RPM in the Troubleshooting
section for more information.

Page 6 9Polaris°
When operating correctly, the cleaner vacuums, sweeps and scrubs all surfaces randomly
throughout the pool. Approximately every three (3) 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
(7) 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.
Thrust Jet
Cleaning the Bag
-> 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 (2) bags.
To remove the bag, detach the velcro
strips. Twist the bag collar and pull up to
free the bag from the cleaner. Unzip both
sides ofthe bag to remove the debris.

Sweep hose is sucked into the
vacuum tube.
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.
. Adjust the sweep hose to a gentle
sweeping motion.
. Check the wheel RPM. If
more than 36 RPM, see Adjusting
the Wheel RPM to reduce flow.
4. Add a sweep hose weight
(part #82).
The cleaner does not clean the
entire pool.
1. Verify that feed hose reaches within
6 inches of the farthest point ofthe
pool. If not, order a new hose section
from your Polaris dealer.
2. Adjust thrust jet to improve coverage.
The cleaner is running in circles on
its side.
1. Check for water inside the cleaner
fioat
. Check the filter bag, if full it can weigh
the cleaner down on one side.
. Check the hose fioats to make sure
they are spaced evenly.
. Check the wheel RPM. If
more than 36 RPM, see Adjusting
the Wheel RPM to reduce flow.
Adjusting the Wheel RPM
lf 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®.
lf count is more than 36 RPM:
- Replace the blue restrictor disk in the UWF
with the red restrictor. lfthe 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.
