FAQ & TROUBLESHOOTING

Neptune NPP Pumps

Can I install the NPP pool pump myself?

  • The pump must be installed in accordance with AS3000 Wiring Standards and AS/NZS 2032:2006 Standards Installation of PVC Pipe Systems. Only qualified, licensed or accredited personnel should install pump.

Where should the NPP pump be located?

  • Install the pool pump on a solid, level, rigid and vibration-free surface.

  • Allow use of short, direct suction pipe.

  • Do not install the pool pump at more than 3m geometrical height from water level.

  • The pool pump must have adequate floor drainage to prevent flooding.

  • Ensure the pool pump is protected from excess moisture.

  • Ensure the pool pump has adequate access for servicing and piping.

How do I prime the NPP pool pump correctly?

  • Release all air from filter and piping systems.

  • In a flooded suction system (water source higher than pump) the pool pump will prime itself when suction and discharge valves are opened.

  • If pump is not in a flooded suction system, unscrew and remove the pump lid; fill pump body with water.

  • Clean and inspect the pump lid's O-Ring and re-install the pump lid by turning clockwise to tighten the lid. Only do this by hand.

  • Priming time will depend on vertical length of suction life and horizontal length of suction piping.

The NPP pool pump motor does not start.

  • Check the switch and circuit breaker.

  • Check the fuses.

  • Check the voltage is not too low.

The NPP pool pump doesn't reach full speed.

  • Check the voltage is not too low.

The NPP pool pump doesn't deliver any water.

  • Ensure the pump is properly primed.

  • Check for a closed valve in the suction or discharge line.

  • Check for leaks or air into the suction system.

  • Ensure the pump impeller isn't clogged.

The NPP pool pump is excessively noisy.

  • Ensure the skimmer basket isn't clogged.

  • A valve in the suction line may be partly closed.

  • Ensure the suction line isn't partly clogged.

  • Ensure the vacuum hose isn't clogged or isn't too small.

 
 

Neptune Variable Speed Pumps

Can I install the NPVS pool pump myself?

  • The pump must be installed in accordance with AS3000 Wiring Standards and AS/NZS 2032:2006 Standards Installation of PVC Pipe Systems. Only qualified, licensed or accredited personnel should install pump.

Where should the NPVS pump be located?

  • As close to the pool as possible.

  • Installed at no more than 1m above water level.

  • Use short, direct suction pipe to reduce friction loss.

  • Away from direct sunlight.

  • On solid, level, rigid and vibration-free surface.

  • In a dry area with adequate drainage.

How do I prime the NPVS pool pump correctly?

  • Ensure the pump is turned off.

  • Release all air from filter and piping system.

  • If in a flooded suction system (water source higher than pump) open suction and discharge valves then release all air pressure.

  • If not in a flooded suction system, unscrew and remove pump lid and fill the wet end with water.

  • Reinstall the pump lid, ensuring the lid's O-Ring is located correctly, free of debris and lubricated with silicone grease. Only tighten the pump lid by hand.

  • Turn the pump on.

  • Release any air pressure from filter system.

What do the buttons do on the variable speed pump?

  • Press START/STOP Button to start and stop pump, for backwashing, to restore controller and to activate auto recovery.

  • Short press MODE Button to scroll between Speed, Clock and Power Consumption displays.

  • Long Press MODE Button when CL: (Clock) is displayed to alter and save clock times.

  • Press SPEED 1, 2 or 3 Buttons when in display mode to select default speed.

  • Short press UP ARROW or DOWN ARROW Buttons to increase / decrease default speed settings by 10 RPM when in display mode. Long Press to increase / decrease rapidly. (This will not alter the saved settings, pump will default back to original setting on next cycle).

  • Long press MODE Button for 3 seconds to enter controller settings. (You cannot enter controller settings whilst CL: Clock is displayed).

  • Press UP ARROW or DOWN ARROW Buttons to scroll through controller settings.

  • Press SPEED 1, 2 or 3 Buttons when in controller settings to shortcut access the default speed settings.

  • Short press MODE Button to alter and save any changes made to controller settings.

  • Press SPEED 2 Button to scroll right and SPEED 1 Button to scroll left between digits.

  • Press UP ARROW or DOWN ARROW Buttons to increase / decrease settings.

How do I set the clock on the Neptune variable speed pump?

  • Whilst in display mode, short press MODE Button to cycle between displays until CL: (CLOCK) is displayed.

  • Press MODE Button and hold down for 3 seconds until digits flash.

  • Press SPEED 2 Button to scroll right and SPEED 1 Button to scroll left between digits.

  • Press UP ARROW Button or DOWN ARROW Button to change time.

  • Short press MODE Button to save setting.

What do the fault codes mean on the variable speed pump?

  • OC = Over Current: Driver's output current exceeds the threshold. This is due to a driver output failure or IPM module damage.

  • OV = Over Voltage: Main circuit DC voltage exceeds the threshold. This is due to over power of the power supply or power supply voltage exceeds controller setting.

  • UV = The main electric current is too low under voltage. This is due to power supply being disconnected, driver discharging, or supply voltage fluctuation is too large.
