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.
