WARNING: 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, oats, 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.

Introduction

Congratulations on the purchase of your new automatic pool cleaner, and thank you for choosing Polaris. The Polaris 3900 Sport is designed to give you years of dependable and efficient service.

Page 3

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. For those 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 of the 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.

Fine Tuning The Cleaner

English

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 Jet

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.

Routine Maintenance

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 of the bag to remove the debris.

Zipper Closure

Cleaning the In-Line Filter Screen

To clean the in-line filter screen, pull it out of the filter assembly, rinse and press firmly

back into place.

CAUTION

Always disconnect the Polaris before cleaning or backwashing your pool filter to avoid potential clogging or damage to the system. Allow the filtration system run for at least five (5) minutes before re-connecting the cleaner.

Storage and Winterizing

Never store the cleaner in direct sunlight. When storing for the winter, drain all the water from the cleaner (freeze damage is not covered under the warranty). Use the Quick Disconnect to remove the UWF® from the pool wall. If

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

Troubleshooting

Page 9

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.

they are spaced evenly.

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.
