II Automatic Pool Cleaner Installation and User’s Guide
Fine-tuning Valves and Connections
Pool pump suction is hazardous and can cause entrapment with severe personal injury or
drowning
. Use vacuum regulator (see instructions below) in pool cleaner system at all times.
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.
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.
For the novice pool owner for whom pool vacuuming is a new experience, please read all of the following points,
installation instructions, and trouble shooting guide carefully.
Please note the following:
• “Vacuum” and “suction” are two words meaning the same thing.
• “Dedicated suction line”, “vac port”, and “vac fitting” are different terms for a hole in the side wall of pool; this
hole is connected to the pump suction and is dedicated to vacuuming.
• Some pools do not have a vac port. If your pool does have one, please read the “Suction Entrapment” warning
above.

II Automatic Pool Cleaner connection and vacuum adjustments can
be similar to using your manual pool vacuum. Please read on.
Valves (Pump, Skimmer, and Main Drain) and Vacuum Adjustments
You may need to spend some time adjusting the skimmer and main drain valves in order to obtain the best vacuum
setting for good cleaner operation. Once you have found the correct valve settings for best operation, we suggest you
mark the valves to ensure repeated success.
At first, set valves to give maximum vacuum to the skimmer or vac fitting you have elected to use.
Too Much Vacuum?
You have too much vacuum if the cleaner climbs up the pool wall past the water line to the point that the cleaner sucks
air and the pump loses prime. Frequent loss of prime will damage the pump. To correct this, adjust the regulator by
turning the adjustment knob counterclockwise. This will decrease the suction. If the cleaner still climbs out and sucks
air, open the main drain valve slightly.
Not Enough Vacuum?
You don’t have enough vacuum if the cleaner moves sluggishly or not at all. Be sure the filter system is clean and the
regulator and all valves are adjusted to give you maximum vacuum. If the cleaner is still not moving, your pump may
not be strong enough to operate the cleaner. Please refer to “Troubleshooting” on Page 12.
