inSTRuCTiOn dOR OpERATing ThE puMp SET:
1.
Check the correct direction of the pump shaft rotation (not relevant in the case of
single phase motors).
2.
Make sure that the motor is filled with pure drinking cold water
3.
Ensure taht all pipe cnnections are tight.
4.
The right method of setting the correct direction of rotation in three phase motor
is as follows.
•
Run the pump set and note the discharge
•
Change the direction of rotation by reversing any two phases in the power supply
•
Run the pump set again and note the discharge
•
Higher discharge indicates the correct direction of rotation
gEnERATOR pOWER SuppLy:
While choosing generator, the starting current and other tolerance have to be taken
into account. Make sure that constant and sufficient power is avaible. During startup,
the voltage must be at least 65 % of the nominal voltage.
ShuT dOWn pERiOdS:
The motor must not remain idle for more than a week since it might lead to jamming
of moving parts. If the pumpset is to remain idle for longer periods, it has to be run at
least once in every week for ten minutes. This will ensure that the pumpset is ready for
service at any desired time.
SWiTChing fREquEnCy:
The life of a submersible pumping system depends upon the average number of starts
per day over a period of months or years. The life of control components such as pres-
sure switches, starters, relays, capacitors, splines and bearings will affect due to exces-
sive cycling. Rapid cycling can also cause motor over heating and winding failure. To
dissipate heat generated current, motor must be allowed to run for minimum 5 minu-
tes. Based on the maximum number of starts per day, the pump capacity, tank size and
other control devices must be selected.
The stand still time of the pump between switching off and switching on again should
be at least 3minutes.
SupERviSiOn:
Generally our motors do not require day-to-day maintenance under normal opera-
ting condition, if properly selected and installed. However, it is mandatory to check the
whole pumping system at regular intervals with regards to current drawn in each pha-
se, voltage, water discharge, draw down water level, starters, cable, wiring, earthing and
other electricals. When any abnormality is noticed or if the motor fails to work, please
refer trouble shooting chart.
Inter changing of well water with pre-filled water may occur during operation. Avoid
removing the pump and motor from the well in freezing condition. To prevent freezing
of motors, care should be taken during freezing climate condition.
vOLTAgE TEST:
Measure the voltage by means of voltmeter at the control box or starter. For three phase
motors measure voltage between the two phases. For single phase motors measure
voltage between the line and neutral.
