WHEN SIZING THE AQUAVAR SOLO² FOR USE WITH ANOTHER MOTOR MANUFACTURER, IS IT RECOMMENDED
TO UPSIZE TO THE NEXT SIZE AQUAVAR SOLO², TO MAXIMIZE THE PERFORMANCE OF THE PUMP?
The Aquavar SOLO² is rated for use with most submersible motors for their given horsepower rating. Please compare
the service factor amps (SFA) on the motor to the maximum output on the drive. If the motor SFA value is higher than
the capacity on the drive than the drive may limit the speed of the motor, which will lower the output performance of
the pump. The amperage data can be found in the Aquavar SOLO² bulletin.
CAN THE AQUAVAR SOLO² RUN WITHOUT THE PRESSURE TRANSDUCER/OR IF THERE IS A TRANSDUCER FAILURE?
Yes, You can bypass or “jump’ the transducer by placing a jumper from the lower terminals to the upper terminals.
The jumper is located to the right of the transducer connections on the inside of the drive. Refer to IM229 for specific
details.
WHAT ACCESSORIES ARE OFFERED FOR USE WITH THE AQUAVAR SOLO²?
The ability to install a float switch, an overpressure switch, or a moisture sensor. These would be installed in place of the
jumper on the switch input. Please reference the Instruction manual for details.
ARE 80 HZ PERFORMANCE CURVES AVAILABLE?
Many 30-80 Hz curves and selection charts are published within the 30-80 Hz ProPak Bulletin.
CAN I USE A FLOAT SWITCH INSTEAD OF A PRESSURE TRANSDUCER WITH THE AQUAVAR SOLO²?
Yes. The Aquavar SOLO² has a switch input for float, pressure, or other non-powered switches. Refer to IM229 for
specific details.
HOW FAR CAN THE FLOAT SWITCH BE FROM THE DRIVE? WHAT IS THE MAXIMUM TOTAL LENGTH FOR
PRESSURE TRANSDUCER CABLE?
The maximum distance of float switch and pressure transducer cable is 200 feet.
IS THE PRESSURE TRANSDUCER AFFECTED BY A VACUUM, OR BY WATER HAMMER?
Yes the transducer can be affected by a vacuum. It is not designed to be exposed to negative pressure and damage
to the diaphragm inside the transducer can result. It can also be damaged by repetitive water hammer. If you suspect
either condition, a gauge guard (6K210) may dampen the effects and protect the transducer. In addition a vacuum
on the transducer of more than 17” Hg will cause the drive to fault out on a 3 blink alarm - sensor fault. In addition the
pressure transducer requires protection from freezing.
WHAT CAUSES A PRESSURE FLUCTUATION OF MORE THAN 5 PSI (ASSUMING THE CONTROLLER IS SET AT 5
PSI NOT 20)?
Pressure fluctuations are the result of changes in demand. So a rapid drop of more than 5 psi could simply be from
opening a valve quickly. It could also be from a rupture in the diaphragm tank or a poorly working check valve.
WHAT IS THE PROPER ORIENTATION AND LOCATION FOR THE PRESSURE TRANSDUCER?
Pressure transducer should be placed close to the tank in the vertical or horizontal orientation. Do not install the
pressure transducer with the pressure port facing up to avoid filling the port with debris. Do not install any valves
(except for a check valve) between the pressure transducer and the pump.
