Hayward SharkVAC Model: RC9740 RC9742 - Page 16

Important Tips • Cleaning the filter cartridge after every use maximizes the unit's performance. • Replace worn brushes. • To avoid clogging the SharkVAC's filter elements, be sure all chemical powders are fully dissolved before operating the cleaner. • In a pool with usually high calcium content, more frequent cleaning of the filter is recommended. • Save the SharkVAC original carton for extended storage or shipping requirements should your SharkVAC require dealer service. • The sealed Motor Unit and the Power Supply contain no user-serviceable parts. Opening them will automatically VOID your warranty. • Remove items such as thermometer, toys and the like from the pool before operating the unit. Such items can jam the cleaner and cause damage to the unit and/or your pool. Troubleshooting If SharkVAC fails to pick up fine or heavy debris: • Clean the filter. It may be clogged. A filter cleaning solution can be used to remove excessive dirt and/or sand If SharkVAC starts working momentarily but then stops working: • Impeller may be clogged or jammed with debris. Check and clean if necessary following the instructions in the maintenance section. • Brush roller or drive tracks are stuck. Check for debris and clean if necessary. • Cleaner performs by both timing and a pool wall detection sensor, which ever comes first. • There are 3 intake ports located at bottom of filter bucket and near the brush roller. Intake ports located next to the roller help collect debris such as leaves and sand better than single intake. • Fine debris such as sand may need a smaller intake port for stronger suction. E-VAC can create a stronger suction with a "high velocity flapper" that can be installed at intake port. 16
