Aquavar ABII Quick Start Guide
Installation Steps:
1. Install the Pump
• Plumb suction and discharge of pump into piping.
• Install a check valve on the suction side.
• Locate the pump as near liquid source as possible.
2. Install the Pressure Transducer
• Install the pressure transducer in the tank tee provided with the unit.
• Locate the transducer within 120” of the controller.
3. Mount the Controller
• Mount vertically in a well ventilated, shaded area with 8 inches of free air
space on every side and temperature between 34º F and 104º F.
4. Connect Input Power
• Connect the 1Ø power from a 20 amp 2-pole circuit breaker.
• Do not use GFCI protection with ABII as nuisance tripping will result.
5. Output Power Connections
• Connect the output power leads from the controller to the 3 motor leads
in the conduit box on the motor.
6. Set the motor Overload Switches (or dials, 3 and 5 HP)
• Complete systems have overloads pre-set at factory.
7. Set the Pressure - Factory pre-set is 50 PSI
• Push and Hold the Increase or Decrease Pressure Adjust Pushbutton
until the desired pressure setting is reached.
• The maximum allowable pressure setting is 85 psi.
8. Set the Application Switches (or dials, 3 and 5 HP)
• Minimum Speed of 10 Hz – the incoming pressure is within 20 PSI of the
desired pressure setting.
• Minimum Speed of 30 Hz – the incoming pressure is 20 PSI or more below
the desired pressure, if pumping from a tank or if drawing a suction lift.
• Ramp Speed – Slow - Low ow; Medium - Medium ow; Fast - High ow
