4.5- Pump/motor installation
1. If the pump is installed in an enclosed area with emission of noxious fumes, the installation must be
carried out in compliance with local and/or national laws by qualified personnel so as to avoid danger.
2. The pump must be in a vertical position over 0.5m from the water bottom (ensure that it is stable
during operation).
3. The suction holes (9) must never be obstructed (e.g. avoid clogging by weed or other matter).
It is therefore preferable that the pump should never be placed directly on the ground or on the bottom
of the well. For example, place the pump on a brick.
4. Inspect the pump shaft as it should be rotating freely.
5. The pump can be installed either using metal piping (which can be used to support the pump) or
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.
