The Doheny's ProJet Free Plus-650 is a battery-operated robotic pool cleaner designed for aboveground pools and swim spas. This instruction manual provides comprehensive guidance for its safe operation, assembly, maintenance, and troubleshooting.
Function Description
The ProJet Free Plus-650 is engineered to autonomously clean the floor of swimming pools and swim spas. Its core mechanism involves a jet head (B1) that rotates 180 degrees. As water flows through the bottom base (E), filters (C & D), and upper cover (B), it propels the robot across the pool floor. If the robot encounters an obstacle, the jet head automatically turns 180 degrees, redirecting the robot in the opposite direction to continue cleaning. Debris is collected and stored in the bottom base (E) as clean water passes through the filter (C). The device is designed to shut off automatically when it is out of water, preventing damage.
Usage Features
Before the first use, the cleaner requires a charge of 4-5 hours, which typically allows for approximately 60 minutes of operation when fully charged. To begin operation, users must turn on the switch, loosen the rope on the float, and place the robot horizontally into the pool. It takes about 20-30 seconds for the robot to sink to the bottom as air pipes out. The length of the rope should be adjusted to ensure it is at the same height as the water level, with any excess rope cut or tied. When the battery runs out, the robot will automatically stop at the edge of the pool, unless unforeseen obstacles prevent it. For optimal performance, it is recommended to turn off the pool's filtration system, as water circulation can affect the robot's movement. Users should also ensure that any salt used for water sanitization is fully dissolved before placing the robot in the water. The cleaner features a latch on the top for easy carrying and removal from the pool.
Maintenance Features
Regular maintenance is crucial for the longevity and efficient operation of the ProJet Free Plus-650. Prior to storage, the robot should be fully charged. If not in use, the battery must be recharged at least once every three months. The charging adapter and cable should be stored separately from the robot. Before storing, the robot and its filters must be cleaned with clean water; detergents should not be used. All water must be removed from the robot, ensuring it is completely dry. The robot and its accessories should be cleaned and dried with a wet cloth. Storage should be in a well-ventilated area, away from direct sunlight, heat, fire sources, pool chemicals, and children. The ideal storage temperature is between 10 °C and 25 °C (50 °F – 77°F), as higher temperatures can shorten battery life.
The manual provides detailed instructions for debris access and disposal, which involves opening the cleaner to remove collected debris. It also outlines procedures for the maintenance and replacement of the impeller and wheels. For impeller replacement, a screwdriver is recommended. The main wheel on one side contains magnets, and for replacement or maintenance of these, users are advised to contact the dealer.
Safety and Troubleshooting
The manual emphasizes several safety precautions. The cleaner is not a toy and should only be operated by individuals older than 8 years who have read the manual. Only the original battery and charger should be used, and the cleaner should only be charged when powered off. It should be stored in a clean, dry location, away from direct sunlight or explosives. Users must ensure there are no sharp objects in the pool that could damage the cleaner. The cleaner's suction port should not be blocked during operation. Disassembly of the cleaner is not recommended without professional guidance from an authorized repair center. In case of an oil leak, the cleaner should be removed from the water and placed in a plastic bag. For any operational issues, the company where the cleaner was purchased should be contacted, and only original parts should be used for repairs.
Regarding the charger, it is for indoor use only and must not be exposed to rain, humidity, liquids, sunlight, or heat. It should be kept out of reach of children and never used if damaged. Handling the cleaner or charger with wet hands or bare feet while charging is prohibited. The charger should be disconnected from its power source when not in use. If the charger wire is damaged, the entire charger must be replaced. Both the cleaner and charger must be completely dry before charging.
Battery disposal must be done properly, as it is a lithium battery. Users are advised to contact local authorities for information on disposal. Disassembling the lithium battery is strictly forbidden. If the battery needs to be removed by authorized personnel, all metal items (rings, bracelets, necklaces, watches) should be removed to prevent severe burns from short circuits. Complete eye protection, gloves, and protective clothing should be worn during battery removal. Smoking, sparking, or open flames near the cleaner should be avoided to prevent ignition of the battery and gas production. In case of acid contact with skin or clothing, immediate washing with soap and water is necessary. For eye contact, flushing with cool water for at least 15 minutes and immediate medical attention are required.
The manual includes a comprehensive troubleshooting guide to address common issues such as the robot not capturing debris, stopping in the middle of the pool, or moving slowly. Solutions range from charging the robot and cleaning the storage area to checking for obstructions and contacting the dealer for replacements of damaged parts like the impeller or battery. It also addresses issues related to the charger's indicator lights, advising contact with the dealer for battery or charger replacement if problems persist, and warning against self-repair of the battery due to potential serious injury and warranty invalidation.
