Disconnecting and removing the unit from the pool immediately after each use will
enhance the cleaner’s life. 150 minutes of operation in a 30’ x 60’ pool should be sufficient
with no more than a few twists in the cord which should be straightened out after each use.

When supplying 230 VAC instead of 115 VAC to the Master control panel, the following
jumper cable switch must be moved.
1. Move the jumper wire connection E9 to E7 230 VAC connection on the RELAY
BOARD just above the transformer.
2. Hard wire the power cord to a dedicated 10-15 amp breaker. The master
control panel draws roughly 3 amps.

Drive Belt Removal
1. Remove right side drive belt.
Note : When putting the drive belts back on, put the LEFT side on first, then the RIGHT side. This
will prevent possible torque damage where the gear box assembly meets the front housing bell,
since the larger support bracket is on the left side of the gearbox assembly.
2. Remove left side drive belt.

Drive Wheel Disassembly
Step 13:
1. Using the snap ring pliers, remove the snap ring from the front wheels and the rear drive wheels.
2. After removing the snap rings from the wheels, pull the front wheels from the base plate and
remove the drive wheels from the gear box assembly.
Note : There is one SS washer on each
side of the gear arm.
1. Front Wheels 2. Drive Wheels
Page 14
Note: There is one 1/8" SS Key on each rear drive wheel It is
important the key is installed into the wheel prior to inserting the shaft.
Page 17

- Using DC Voltmeter, check voltage between the yellow wire and the blue wire. 24 VDC should be
present while pushing the LEFT TURN button on the remote
- Using DC Voltmeter, check voltage between the yellow wire and the brown wire. 24 VDC should be present
while pushing the RIGHT TURN button on the remote.
- Using DC Voltmeter, check voltage between either the brown or blue wire to yellow. 24 VDC should be
present while pushing the REVERSE TURN button on the remote.

1. After testing the RELAY PCB Board (Step 24), if the tests do not match the correct voltages, then
the RELAY PCB Board will need to be replaced.
2. If the problem still exists after replacing the RELAY PCB Board, remove the cannon plug from the
master control panel. Insert the jumper wire into the 2 center ports of the connector plug at the
master control panel. Repeat steps 24 & 25. If steps 24 & 25 pass the testing, the motor and cord
need to be test separately to determine which one needs to be replaced.

Voltage Check to Swivel
To verify voltage is passing through the power supply cord to the swivel :
1. Power the system off
2. Disconnect the power end connection at the swivel
3.Power the system ON and make sure the RUN light is illuminated.
4. Put meter leads on the black and white ports. 115 VAC should be present. If not, verify
breaker is good, ON switch is ON, and all power is correct.

Sensor Bar adjustments and other minor repairs (Make all adjustments in ¼" increments)
A. Raise Sensor Bar if machine:
1. Fails to climb out of deep end.
2. Turns or hesitates on pool drain.
3. Turns away from curved wall too soon.
B. Lower Sensor Bar if:
1. Tips over before tripping or sensing wall.
2. Turns or hesitates on pool drain.
C. Sensor Bar adjustments required if machine turns in circles or twists cord:
1. Sensor bar not level or too high, possibly hitting the hood.
2. Thread on reversing arm is worn or stripped, not allowing reversing mechanism to disengage.
3. Sensor Bar Cable screws are loose.
4. Sensor Bar Cable is broken.
5. Drive Wheel is broken.
Check Sensor Bar regularly and keep the sensor bar level at all times !
Loss of vacuuming action
1. Filter may be clogged, slowing the flow of water through the unit. Clean the filters.
2. Suction area may be obstructed by large debris. Unplug power cord and remove obstruction.
No apparent power
1. Electrical outlet may be dead. Check electrical GFCI outlet. Check Fuses and breakers. Verify power switch is on.
2. Object lodged in the impeller.
3. Unit runs for a short distance and stops. Check for over load of the electrical circuit or faulty motor. DO NOT USE EXTENSION CORDS
4. Motor runs but machine becomes or is motionless. Gear box could be worn or drive pin could be sheared.
Machine tips over
1. Filters are dirty.
2. Sensor Bar set too high.
3. Tipping in certain situation can be prevented by purchasing a float and installing per instructions.
Disconnecting and removing the unit from the pool immediately after each use will enhance the life of the cleaner. 4 hours operation in a
50’ x 100’ pool should be sufficient with not more than a few twists in the cord which should be straightened out after each use.
