The wet function bench test (Part #9-100-6005)
removes the guesswork from bench repairs. It
allows you to test all the operational functions
of the cleaner and back-up valve at your facility.
The test can be performed in a test tank, deep
sink or outside the store by connecting it to a
hose or faucet. Streams of water will be emitted
from the Polaris during testing, so choose an
area that will not be damaged by water.
Equipment Needed:
2 x 4 piece of wood
Brick or something similar like a deck-o-seal can
Piece of black tape
Checking the Feed Hose
As a regular practice, have the customer bring
in both the cleaner and the feed hose. Start by
doing a visual hose 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 there is one float pushed as close to
the back-up valve as possible on the side
opposite the cleaner. There should also be
one float four feet and one float seven feet
upstream from the back-up valve.
4. Verify there are no holes in the feed hose.
5. Always review hose cutting with the
customer.

Begin Testing
1. Attach the feed hose to the Polaris.
Disconnect the quick disconnect from the
hose and attach the inlet fitting. If the feed
hose is unavailable, attach the inlet fitting
to the bench test hose provided. Attach the
bench test hose directly to the Polaris. See
the diagram below.
2. Attach the inlet fitting to the water source.
3. Set the Polaris on the piece of wood to allow
the wheels to spin freely.
4. Remove the bag. Place the brick over the
vacuum tube to cover the vacuum jets.
Secure the sweep hose and turn on the
water. Adjust the water pressure until the
wheels turn.
Troubleshooting
1. Verify that all the wheels are turning. If not,
check for:
a. A clogged drive jet.
b. A broken wheel axle or stripped single-
side wheel.
c. A broken or damaged drive belt or
stripped transfer pulley.
d. 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 or loose
hose clamps.
