PIPE SIZING: ENSURE that a suitable pipe size is used
–
typically pipe the same size as the pump outlet for short run, go up a size for longer piping
distances, up to 10m. For piping that is longer than 10m please confer with your dealer or pump specialist to be certain you do not restrict the pump as
this will reduce the performance and the lifespan of the pump.
BE AWARE that a long pipe that is too small has the same effect as trying to “lift” the
water too high and the performance of the pump is greatly reduced or may stop altogether (for example a 20mm pipe over 30m would severely restrict
the performance).
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 Limited 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 - 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 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 done 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 TROUBLE-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 t
he image on 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. (float on the VF (Vertical Float)
series is different to the image on page 1)
(D)
Pump not pumping properly;
1.
Too high head or pump under specified > Check specifications.
2.
Too low water level > Check the water levels
3.
Pipework is too long > refer to PIPE SIZING:
4.
Pipework is too small > both these factors (3 & 4) will severely reduce the output of any pump > the longer and smaller the pipe, the lesser the flow you
will get.
