HOW DO I SIZE THE AQUAVAR SOLO² FOR THE APPROPRIATE PUMP/MOTOR COMBINATION?
The Aquavar SOLO² can accept any 3 phase, 230 volt 4” submersible motor up to its rated amperage.
The Aquavar SOLO² has an adjustable overload switch to dial in the correct full load or service factor amperage.
CAN I USE A 208V MOTOR?
Yes, The Aquavar SOLO² monitors amperage draw from the motor and as long as it is within the current rating set on
the overload switch. Ensure the input voltage is within ≤ 196V and < 265V. The user may see a drop in performance if
the SFA setting is less than the motor’s SFA rating.
CAN I RUN THE AQUAVAR SOLO² UP TO 80 HZ?
Yes, as long as the rated amperage for the motor at 80 HZ does not exceed the overload switch setting or max amps
of the drive. Switch the setting on the controller to 80 HZ max speed. Example: If you have a 1.5HP submersible wet
end and use a 3HP motor, then size a 3HP Aquavar SOLO² (3AS30) which is rated for 10.9 max amps, which is equal to
1.5HP hydraulic performance.
WHAT ARE THE RECOMMENDED SPARE PARTS FOR AN AQUAVAR SOLO
2
? CAN I REPAIR?
The pressure transducer (sensor) is recommended to keep on hand for repair. In addition the UIB, Fan kit and
transducer cable are also replaceable.
CAN I MOUNT THE AQUAVAR SOLO² CONTROLLER IN AN OUTSIDE ENVIRONMENT? IF SO WHAT ARE THE
MAXIMUM CONDITIONS ALLOWED?
The Aquavar SOLO² series is rated UL type 3R enclosure, outdoor or rain-tight and can accept ambient conditions up
to 122º F. If the controller gets too hot it will reduce speed to cool off and this will affect pump performance. Caution is
advised for humid and poor air quality environments.
WHAT IF MY AQUAVAR SOLO² CONTROLLER IS NOT PUTTING OUT THE RECOMMENDED OUTPUT IN GPM?
Check rotation of the motor, verify ambient conditions, check motor wire and splices and finally check the pump for
clogging or valve operation. Verify SFA setting matches the motor’s SFA rating. Additionally lower input voltage can
reduce pump performance.
WHY DOES MY PRESSURE DROP SUDDENLY DURING START UP?
A properly sized air diaphragm tank and pre-charge (see IOM) is necessary during rapid use of water at start up. Look
at the pump depth, static levels and maximum system demand (GPM) to determine how much time is necessary for the
water to reach the transducer placement. Remember, the Aquavar SOLO² controller is a soft-start and will take a few
seconds to respond depending upon the distance between the pump discharge and transducer placement.
WHAT ABOUT INTERFERENCE WITH AM RADIO OR OTHER DEVICES?
The Aquavar SOLO² controller has several design features that reduce the unwanted electromagnetic interference
(EMI) sometimes contributed to VFD acceptance. Levels are established by the FCC for residential and commercial
installations. It is suggested to always keep Aquavar SOLO² power and motor leads away from sensitive devices and
ensure proper grounding for all components of the Aquavar SOLO² system including motor, piping, breaker and main
panel.
