Handbook

For 360:
Verify there is one float pushed as close to the back-up valve as possible
on the side opposite the cleaner and two additional floats installed one
4 inches upstream and one 7 feet upstream from the back-up valve.
4. Always review hose cutting with the customer. For complete hose cutting
procedures, refer to page 3, or the installation section of the cleaner’s
owner’s manual.
Wet Function Bench Test
For 380: Disconnect the clear hose from the white feed hose and connect the
clear hose, using the swivel, directly to the end of the Wet Function Bench
Test hose. (If you don’t have the clear hose, attach the Wet Function Bench
Test hose directly to the Polaris head.) Attach the other end of the clear hose
to the Polaris head, and then thread the inlet fitting to the water source.
For 360: Attach the feed hose to the Polaris. Disconnect the quick discon-
nect from the hose and attach the inlet fitting. If the feed hose is unavailable,
attach the inlet fitting to the bench test hose provided and attach the bench
test directly to the Polaris. Attach the inlet fitting to the water source.
Set the Polaris on a brick or piece of wood (2 inches x 4 inches) or something
similar to allow the wheels to spin freely. Remove the bag. Place a coping
brick or deck-o-seal can over the vacuum tube to cover the vac jets. Secure
the sweep hose and turn on the water. Adjust water volume to activate
the wheels.
1. Verify that all the wheels are rotating. If not:
• Check for a clogged drive jet.
• Check for a broken wheel axle or stripped single-side wheel.
• Check for a broken or damaged drive belt or stripped transfer pulley.
• Check for a pebble binding the drive train gears.
2. Verify that there is water flow through the sweep hose and thrust jet.
If not:
• Check the water management system for leaks.
• Check the water management system hoses and hose clamps.
3. Carefully lift the brick on top of the vacuum tube and verify that there are
three even, distinct jets in the vacuum tube. It may be easiest to
check this with the cleaner flipped upside down. If all distinct jets are
not present:
• Check the water management system hose clamps.
• Clear the vacuum jets which are obstructed.
• If additional spray is present, check the water management system for
leaks or loose hose clamps.

V. TROUBLESHOOTING ON THE BENCH
Quite often retail dealers and service centers are faced with a Polaris which is
brought into the bench (retail store or service department) with no detailed
operational information other than “it isn’t working”or “it stays on the steps.”
This does not give the technician much in the way of direction for trou-
bleshooting the cleaner. Often the technician identifies and fixes an obvious
problem without looking further for other less visible problems within the
cleaner. When these less visible problems are not caught on the first trip to
the bench, and return trips are required, or when the cleaner’s operation is
compromised due to incomplete service, the customer can lose confidence in
both the dealer and the product. The following tips will help in troubleshooting
the Polaris 380/360 and will allow you to solve your customers’ problems cor-
rectly the first time.
The Wet Function Bench Test Kit (380 part #G-10; 360 part #9-100-6005)
removes the guesswork from bench repairs. This kit allows you to connect
the Polaris to a water source (i.e. garden hose or water faucet) at your bench
facility and test all of the operational functions of the cleaner head and back-
up valve. The Wet Function Bench Test can be used both inside a store with
a test tank facility or a deep sink, or outside of the store. High pressure water
streams will be emitting from various orifices of the Polaris during the testing,
so be sure to choose a work area that will not be damaged by water.
The Testing Begins
Have the customer bring both the cleaner head and the feed hose into
the bench.
Visual Inspection
Start by doing a visual inspection, checking the following:
1. Verify the filter screen is clean.
2. Verify the swivels turn smoothly and the arrows are pointing toward the
cleaner head.
3. Verify the hose cutting.
For 380:
Verify hose floats are evenly spaced on the white hoses and both the
white hoses are the same length. Verify the clear hose is cut to the depth
of the pool. For the 380 clear hose, verify there is one float against the
back-up valve on the side opposite the cleaner and another float within
2-3 feet. For the 280/180 clear hose, verify there is one float on either
side of the back-up valve and another float within 2-3 feet.
