9.ELECTRICAL CIRCUIT & WIRING;
a.Installation and electrical wiring must adhere to state and local codes and must be completed before using the pump. All
Electrical wiring must be performed by a Licenced Electrician.
b.Pump must be connected to a circuit of suitable size for the power requirement of the pump, with a RCD (safety switch)
having a rated residual operating current not exceeding 30mA – recommended type is a circuit breaker with integrated
RCD.
c.Plugging into shared outlets or extension leads may cause low voltage supply to the motor, causing blown fuses, tripping
of motor overload, or burnt out motor. The recommended method is to have the pump on its own separate circuit.
d.Surge Protection - We recommend that a surge protector is used to protect the electronics of the pump, as damage due
to power surges is not covered by the Warranty
e.All electrical installations must be earthed in accordance with Electrical Regulations
f.The voltage of the power supply must match the voltage of the pump – 230 to 240 volt AC except for 3-Phase pumps
which are 415Volts. We do not recommend generator power.
10.WARRANTY VOIDED: The following may cause severe damage to the pump and automatically voids the warranty:
a.Using an extension cable for power supply.
b.Cutting the earth pin off the plug or using an adapter fitting or double adapter.
c.Working on the pump while it is connected to the power supply.
d.Removing/opening the cable entry point, or the motor housing, unscrewing impellor, or otherwise removing impellor
seal (except if this work is one by a qualified Pump Technician)
e.Pumping chemicals, corrosive liquids or flammable liquids.
f. Pumping hot liquids (Exceeding the temperature on the nameplate)
g. Lifting or moving the pump using the power cable.
h. Dry operation which will destroy the pump seals.
i.Installing the pump inside a tank (enclosed space) in such a manner as you cannot remove the pump without getting
inside the tank – this is against best practice and no warranty cover applies in this case.
11. PUMP NOT PUMPING
If the pump does not pump water, check the discharge pipework is free from airlocks or other obstructions. Check that any non-return valves
are fitted with the arrow in the correct direction of flow, and are not jammed shut with glue or debris. For further help, refer to the TROU-
BLE-SHOOTING section.
12. OVERLOAD PROTECTION – most models have a built in thermal protection switch. The pump stops if an overload condition occurs. The motor
restarts automatically after it has cooled down when the built in thermal protector resets itself. If this problem reoccurs - check as per Trouble
Shooting
13. IMPORTANT NOTES
a. Do not switch the pump on and off frequently, as this will cause damage to the electronics and void warranty.
b. If the pump is idle for a long period of time or in very low temperature, it should be removed, washed clean and stored in a dry & safe place.
14. COMMERCIAL &/OR INDUSTRIAL USE: specific applications in commercial or industrial situations require specialist advice which may not be
covered in this instruction manual. It is the installer & user’s responsibility to obtain specialist advice and to ensure that the pump used is suitable
for their application. Warranty is limited to replacement only, of pumps that are proved to have a manufacturing defect, when used in SUITABLE
commercial or industrial applications. No warranty applies when used in unsuitable applications.
TROUBLESHOOTING CHECKLIST
CAUTION:
SHUT OFF POWER TO THE PUMP BEFORE HANDLING
Check the following before requesting service or repair.
A call out fee normally applies for field services and additional labour cost may apply.
PROBLEMS & POSSIBLE CAUSES & RESOLUTIONS
(A) Pump does not run;
1.Check is the water level in tank too low to lift the float switch > this is the normal operation of the pump.
2.Circuit breaker or Safety Switch is off or the fuse has blown > Turn all Power OFF before attempting service - if it trips again after turning on,
the pump might be burnt out – replacement is normally the most economical option.
3.Pump plug is not connected properly, or has been flooded or wet > Isolate power at main switch, remove plug and allow to dry. If the problem
continues, contact a licenced electrician to fix the power outlet so as it is protected from the weather.
4.If all of the above are OK, then check pump for clogged impellor > clean the impeller
5.Thermal overload switch in the pump has activated > investigate why this has occurred before turning it back on, check that the pump is not
clogged, check that the outlet pipework is not clogged.
(B) Pump runs but does not deliver water;
1.Check Valve is installed backwards. Arrow on valve should point in direction of flow.
2.Check Valve is jammed due to debris or glue etc.
3.Discharge shut-off valve (Ball-Valve or Gate-Valve) may be closed.
4.Impeller or volute openings are fully or partially clogged > clean the impeller
5.Pump is air-locked. Start and stop a couple of times. If this is not successful, you might need to remove the pump to check for blockages.
6.Vertical pumping distance is too high > Reduce distance or upgrade to a larger pump.
(C) Pump runs and does not stop;
1.Float is stuck in up position > Be sure float operates freely in the sump, premature failure will occur if the pump runs continuously, which is not
covered by warranty.
2.If the pump continues to run when the float is in the “Fully down” position (as per the image on the left at the top of page 1 of this manual)
– the pump must have a defective float switch > Call our warranty dept on 1800 807 604 for a replacement, if it is within the warranty period.
(Note, the float on the VF (Vertical Float) series may be different to the image on the right hand side of page 1)
