manual. When troubleshooting an Aquavar system, always break down into the following
components:
1. Aquavar programming — check default settings recommended for single pump, multi-
pump, slave pump etc.
2. Electrical supply/ motor/ wiring/grounding — check your supply voltage, motor
wiring, transducer wiring, and grounding.
3. Mechanical/Pump/ Rotation — check your pump rotation, rubbing or other mechanical
problems. Pump “ run out”.
4. Hydraulic System/ Piping — check to ensure proper suction and discharge piping
layout, proper NPSHa, air entrainment, vortex, friction loss, system curve compensation
etc.
5. Environment — protect from high temperatures, direct sun, freezing temperatures, high
altitude, dust, vibration, lack of air flow.
