The MAYTRONICS 9991414-r1 is a cartridge assembly and bottom lid conversion kit designed for select Dolphin robotic pool cleaners. This kit includes an ultra-fine filter cartridge assembly and a replacement bottom lid that work together to convert the cleaner from its original filter configuration to a cartridge-based filtration system. The cartridge assembly captures fine debris particles that pass through standard filter bags, improving overall water clarity. Installation is performed by pool service technicians or experienced pool equipment installers as part of a scheduled maintenance or upgrade procedure.
This conversion kit is intended for residential robotic pool cleaner applications. It is used when upgrading or restoring a compatible Dolphin unit to cartridge-based filtration. The kit is suited for pools where fine particulate debris such as algae, fine sand, or dust is a recurring issue. The bottom lid and cartridge assembly are matched components that must be installed together to ensure proper fitment and filter sealing.
The 9991414-r1 is compatible with the following Maytronics Dolphin models: Deluxe 4 (99996351, 99996353), Deluxe 5, Triton, Nautilus, and Premier.
Installation is typically performed by a pool service technician. Before beginning any service, power down the robotic cleaner and disconnect it from the power supply unit. Remove the existing bottom lid and filter assembly before installing the new cartridge assembly and bottom lid from this kit. Consult the Dolphin unit service documentation for proper assembly sequence to ensure the bottom lid seats and latches correctly before returning the cleaner to service.
