Fine-tuning valves and connections

WARNING! 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.
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.
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.
For the seasoned pool owner: The 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.
