flexible piping.
6. In the case of flexible piping, the pump must be supported by a cable made of material which is not
liable to deteriorate in the long term.
The cable should be passed through the two grommets (7) on the cover.
7. Check the pump, motor, cable, or the socket connection whether they are in good condition.
All the screws connected should be tightened.
8. After connecting the pump to the power supply, let the motor run idle for a few seconds to check
the pump is correctly starting, operating, and motor is running in proper direction.
9. Note:- you may use plastic or rubber clips to support the power cord to the discharge at regular
intervals of 3 meters (10feet).
- ensure that discharge pipe joints are tightened to prevent loosening due to the torque of motor.
4.6- Operation
1. Before starting the pump, check:
- the direction of motor rotation: trial-run the pump for no more than 1 minute to check the motor
rotates counter clockwise (when looking at pump from above);
- that electrical connection is correctly setup;
- that the electrical cable and drain hose are properly laid to avoid accidents;
- that check valves (if fitted) are opened
2. Check all joints of water pipe to determine water does not leak and soak any electric component.
3. Start the pump to check the ampere value and the condition for water to be discharged by the pump.
If it is under normal conditions; then you may let the pump continue operating until water is clean and
unblocked.
4. After starting, check that motor operates and stops without noise and vibrations.
5. After operating for at least 15 minutes, check pump output, motor input, lowest level of water and
other characteristics.
All above should be steady and in accord with the assigned characteristics.
6. Check the pump performance whether the capacity of pump should be in 0.7 ~1.2 times rated
scope, otherwise the pump operating is in abnormal condition, so the motor may overheat, even burn.
7. If any abnormal phenomenon appears, such as abnormal sound, lack of water or intermittent flow,
you should stop the motor immediately and investigate the reasons.
Regularly check water level during pump operating so as not to fall under pump recommended lower
level, as the pump cannot operate if water level is low.
Pay attention during cold temperatures (when air temperature is below 4°C): to prevent frost-broken
the pump body.
8. Do not wash, swim and pasture domestic animals in water within the pump working area for about
two square meters.
9. Strictly forbid anyone to touch the pump by hand when under power so as to avoid accident.
4.7- Floating switch
4.7.1- Active float switch (Fig.2)
1. The pump must be in a vertical position: ensure that it is stable during operation.
2. Ensure that the float switch can move freely.
3. The suction holes must never be obstructed. It is therefore preferable that the pump should never be
placed directly on the ground or on the bottom of the well, pond or vessel.
For example, use a brick to support the pump.
4. Start pump by pressing On/Off switch.
5. The float switch (10) enables the automatic start and stop of the pump.
When the water rises to reach approximately 50cm or angle over 45, the pump starts up.
When water level has lowered to approximately 5cm or angle below 45, the pump will stop
automatically.
6. By shortening the length of the cable between the pump and the float, it is possible to modify the
