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
fl
oating cable from the cleaner to the
test box (see Figure 2).
7.
If the cycle completes without
fl
ashing lights, the
fl
oating cable and cleaner head have successfully
passed the test.
8.
If the diagnostic box
fl
ashes 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.

The pump motor should start
fi
rst. Check for air
fl
owing from the exhaust on the back end of the
cleaner (see Figure 4).
6.
Next, the drive motors should start within
fi
ve (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.
