This will notnecessarily represent the complete cleaningcycles run.Page 32

Using The Scanner ToolOut of Water0Times1.2.3.4.5.6.7.Out of Water CausesAttempting to run the unit out of the water/pool.Air trapped in the filter after placing the unit in the water.Bench testing in manufacture or repair.Machine climbing too high above the waterline.Low voltage at power source.Low voltage from use of an extension cord.Worn or defective pump motor, drawing less than 1amp at 24 volts.The number of times the unit has realizeda low load on the pump motor.Pump Overcurrent0TimesPump Over Current Causes1. Debris around the pump impeller. Remove impeller andinspect for hair or grass around pump shaft.2. Defective pump motor. Motor should turn smoothly byhand with only a slight resistance from the shaft seals.Number of times the pump motor has realizedan over load condition. Unit will stop after 3-5seconds in this condition.Page 33

Using The Scanner ToolDrive Overcurrent0TimesDrive Over Current Causes1. Unit caught under a ladder2. Debris caught in traction drivebelt and or pulleys under side cover.3. Riding or standing on unit during operation.4. Defective wheel tube bearings or side cover idler bearings5. Defective drive motor.Number of times the drive motor has realizedan over load condition. Unit will stop after 3-5seconds in this condition.Water Detected0TimesNumber of times the water hascontacted the sensor inside themotor box. Continuouscontact will stop operation of theunit. Severe water damage willcause a ‘Communication Failure’when hooked to the scanner.Page 34

Testing Power Supply & Flotation CordCheckPower andCommunicationConnectionsFailureCommunication Failure Causes1. Damaged power supply, check for 21-25 volts DC2. Water inside power connection to motor box, checkseal at motor box and for breaks in flotation hose3. Damaged flotation cord, check for ohms reading of .4 to .8 ohmsFlotation cord test. Remove cord frommotor box and check ohm’s readingbetween each pin and wire end. .4 to.8 ohm’s is acceptable.Circuit failure between power supply andand the PCB (printed circuit board)in the motor assembly box.DC voltage test on powersupply21 to 25 volts dc is acceptable.The powersupply is not repairable andmust be replacedif defective.Insert voltage probes in pin terminal 1 and 2 andturn on power supply to test.Page 35

Troubleshooting¾Startup Machine will sequence between pump and drive motor for up to 1 minute. During this time the microprocessor is sampling motors for proper electrical load.¾Mapping Sequence At about 2 minutes the machine will begin mapping the immediate section of the pool. Wall climbing will be every other floor pass and the time on the wall climb willbe random. The pattern is not permanently imbedded and will be reconfigured with eachuse of the cleaner.¾Wall Climbing Once in the cleaning cycle the machine will typically perform a wall climb everyother floor pass and vary the amount of time on the wall. At random the machine will perform a free fall from the wall to aid in randomnavigation. The startup of each 4 hour cycle may require up to 30 minutes as the machinemeasures the pool configuration before climbing the walls completely to the water line.Page 36

Troubleshooting¾In Process Mapping As the unit encounters large changes in pool configuration it will revert to themapping process for a few passes to adjust itself to the change in shape. Mapping will take several passes and is undetectable from normal operation.¾Navigation The unit navigates itself primarily by running in a diagonal direction at the water line. This is the key to complete pool coverage.¾Shutdown The machine will shut down after 4 hours for the standard TigerShark. TigerShark QC will shutdown after 90 minutes if the Quick Clean LED isilluminated, or after 4 hours if “Full Cycle” is selected. The power supply will continue to supply low voltage to the unit and the diagnosticmemory will continue to record hours until the power switch is turned off.Page 37

Troubleshooting¾Will not climb wallsFilter Too Dirty to Allow Proper Machine Performance Pool condition is unacceptable for cleaner use. Sweep walls, vacuum pool, balancechemicals and algaecide to an acceptable swimming condition. Resume use ofTigerShark for pool maintenance as often as required. Increase frequency of TigerShark filter cleaning, especially during the initial use.Filter may have to be cleaned 30 minutes to 3 hours in the first few cycles until thepool is in an acceptable condition. Algae on pool walls. Brush walls and chemically treat for algae. Increase frequencyof TigerShark use and filter maintenance. D.E. or sand filter leak. The primary pool filter may leak diatomaceous earth or finesand that can overload the filter. Service and inspect the pool filter system, vacuumthe pool and resume use of the TigerShark for pool maintenance.Page 38

Troubleshooting¾Will not climb wallsPool design or configuration The pool bottom corner design may be too sharp. Some pool designs feature asharp, 90 degree bottom corner. A guideline for the best machine performance is acorner radius similar in contour to a basketball. In a clean pool the machine symptomwill be movement to the wall with repeated bumping and infrequent climbing, ThePVC rollers can be replaced with foam rollers only if a dirty pool condition isruled out. Clean vinyl or tile pool surface is too slick. Replace the PVC rollers with foam rollersonly if a dirty pool condition is ruled out.Machine problem Broken impeller. Inspect and replace it if required. Inspect for tears that may allowobjects to pass through and entangle or damage the impeller. Defective pump motor can be identified by a slow or non-rotating impeller. Replacethe motor box assembly.Page 39

Troubleshooting¾Will not climb wallsConfusion on normal operation The startup of each 4 hour cycle may require up to 30 minutes as the machinemeasures the pool configuration before climbing the walls completely to the waterline. During the 4 hour cycle the machine will randomly re-measure the pool configurationor release itself from the wall. The machine will not climb the walls during this 15-30minute cycle.¾Climbs Too High, Falls off Wall at Waterline, Blows AirBubbles Through the Exit Venturi Above average traction in a clean pool. Install the Restrictor Plate Kit RCX11206 inthe venturi. Inspect bottom lid filter plate gasket and replace if torn or missing. Set handle position at an angle, machine should never operate with the handle in thecenter or straight position. Check water chemical balance.Page 40

Troubleshooting¾Runs only a few seconds or minutes Make sure the machine is submerged in the water. An out of water detection within afew minutes will cause the machine to stop if not completely submerged. Check electrical source for proper voltage. If using an extension cord, test for proper voltage. An extension cord is notrecommended. Check for missing or broken impeller blades. Check for pump impeller obstruction. Check pump impeller for hard rotation and pump motor binding.¾Cord twisting Alternate handle position with each use. Be sure machine is not getting caught on obstructions in the pool such as raiseddrains, in floor cleaning heads, toys, etc.Page 41

Troubleshooting¾No movement but impeller turns Drive motor pin or drive motor is broken possible due to overload during use. Toavoid repeat failure, follow-up with the customer for obstructions in the pool such asa ladder. The Scanner will display a Drive Over Current signal if the machine hasbeen caught on an obstruction. Check for belt or roller obstruction Check for broken impeller Check for missing roller tube bearing screws, 2 per side.¾No movement and no pump discharge Check with the scanner for communication failure, see scanner section to diagnose. Check for impeller obstruction. Check for broken blades. Check electrical source for proper voltage range of 115-125v, including extensioncord if used.Page 42

Troubleshooting¾Debris falls from unit when removed from pool Filter overload, increase frequency of filter cleaning. Large debris blocking intake. Remove large debris from pool before using machine. Drain flaps out of place on bottom lid. Snap flaps back into place. Avoid dropping orthrowing machine into the pool.Page 43
