WARNING
FOR YOUR SAFETY - This product must be serviced by a contractor who is licensed and qualified in pool equipment by the
jurisdiction in which the product will be installed where such state or local requirements exists. In the event no such state or local
requirement exists, the installer or maintainer must be a professional with sufficient experience in pool equipment installation and
maintenance so that all of the instructions in this manual can be followed exactly. Before installing this product, read and follow
all warning notices and instructions that accompany this product. Failure to follow warning notices and instructions may result in
property damage, personal injury, or death. Improper installation and/or operation will void the warranty.
Improper installation and/or operation can create unwanted electrical hazard which can cause serious injury, property damage, or
death.
Connect unit to receptacle protected by a ground fault circuit interrupter (GFCI). Such a GFCI receptacle should be provided by
a qualified installer and should be tested on a routine basis. To test the GFCI, push the test button. The GFCI should interrupt
power. Push the reset button. Power should be restored. If the GFCI fails to operate in this manner, the GFCI is defective. If the
GFCI interrupts power to the pump without the test button being pushed, a ground current is flowing, indicating the possibility
of an electric shock. Do not use this product. Disconnect the cleaner and have the problem corrected by a qualified service
representative before using.

A. Testing Cleaner Head and Floating Cable
1. Set the cleaner head on a block of wood or some
object that allows the cleaner wheels to be elevated
from the surface.
2. Plug the Polaris Quick Diagnostic Test Box into a
GFCI protected outlet.
3. Connect the floating cable from the cleaner to the
test box (see Figure 2).
7. If the cycle completes without flashing lights, the
floating cable and cleaner head have successfully
passed the test.
8. If the diagnostic box flashes red lights at any
time during the test or the cleaner head does
not activate, proceed to Section C: Diagnosing a
Defective Motor Block or Floating Cable.
B. Testing the Control Unit

4. Determine the corresponding button for the model
being diagnosed (9300 or 9300xi). Press the button
to start the test (see Figure 3).
2. The drive cycle will turn on and will last for
approximately five (5) seconds.

five (5) seconds. If the cleaner does not drive
forward for approximately five (5) seconds, then the
control unit is defective and must be replaced.

5. The pump motor should start first. Check for air
flowing from the exhaust on the back end of the
cleaner (see Figure 4).
6. Next, the drive motors should start within five (5)
seconds after the pump motor starts. Take note
which direction the drive motors are rotating. The
drive motors drive the two (2) front wheels. Verify
that the two (2) front drive wheels move forward
then in reverse. After ten (10) seconds, all motors
should stop.

4. If the pump and drive motors drive, the control unit
has passed the test successfully. Turn off the power
to the control unit.
NOTE The control unit is programmed to shut down
power to the cleaner head within ten (10) sec-
onds in order to protect the motor from damage.
C. Diagnosing a Defective Motor Block or
Floating Cable
1. Open the cleaner top and remove the filter canister.
Unthread the screw securing the prop guard in place
and remove the propeller guard (see Figure 6).
