Troubleshooting (continued) • For the cleaners used in areas that have a lot of sand the cleaner may need to be rinsed with water at all flapper (filter bucket's flapper is at intake port) areas and may need rinsing at the dome push button to allow free operation. • Cleaner may get stuck if a high main drain is installed in the pool. Cleaner may remain lodged on the drain for a short period of time, but will eventually free it's self by virtue of the cleaner's embedded program. • The filter bucket is designed to be cleaned with the filters installed for normal clean up. For deep cleaning, the user can remove each filter cartridge and clean separately. • During the normal operating cycle of the cleaner, the handle side of the unit will rise from the pool bottom to allow the unit to clear obstacles, such as elevated main drains and stair steps. • It is normal to see the cleaner ride the wall for a short period of time; this allows the unit to change position in the pool to assure full bottom coverage. • Perception of cleaner performance: Confusion may exist over the perception of how the cleaner operates at different times during each cycle. It is important to judge the performance of the cleaner by observing improved pool cleanliness after the cleaner has run a complete cleaning cycle. • If a cleaner has poor coverage of the pool in one cycle or only covers a small area, check the filter and clean if necessary and make sure the unit is not getting caught on drains, floor cleaning heads or toys. The user may try starting the cleaner in different locations to find the optimum cleaning location. • If debris falls from cleaner while removing from pool, it may be caused by filter overload, increase frequency of filter cleaning. Assure that there is no large debris blocking any of the three intakes. Large debris must be removed from the pool before using machine. If drain flaps are out of place or stuck by sand or leaves in the open position, the flaps can be snapped back into place, after cleaning the area. • Avoid dropping or throwing machine into pool. Place cleaner away from the pool wall but do not throw the cleaner in the pool. • If the flotation cord gets twisted which can be caused by the cleaner getting stuck on large objects such as rocks, toys or main drains, it can be straightened by laying the flotation cord at full length (if possible) in the sun; heat from the sun will help reduce the twisting. • If a high level of debris is visible through the dome windows, remove cleaner quickly from the water to reduce the chance of the debris escaping the filter bucket and reentering the pool. 17
