NOTICE: Each pool's hydraulic system and vacuum connections are different. Be sure you have installed the
vacuum regulator before you "fine-tune" the system. This not only regulates vacuum, but also acts as a safety device.
WARNING — Suction entrapment, injury, and drowning hazard. If your pool has a dedicated suction port
("vac port") for vacuuming or for an automatic pool cleaner, it must be covered when not in use. A
spring loaded safety cover (the "Vac Port Fitting") is included with this pool cleaner. Install it on the
vac port to prevent entrapment and injury. For details please refer to the Vac Port Fitting instruction
sheet included with your cleaner.
