IV. GETTING STARTED
a- Before installing the water pump, make sure that the power supply mains is earthed and complies
with regulations.
b- Do not underestimate the risk of drowning if the installation has to be performed in a well at a
certain depth.
c- Make sure there are no toxic discharges or harmful gases present in the atmosphere.
d- If the installation involves welding, take all necessary precautions to avoid explosions.
e- Ensure that the well is free of sand and other deposits and that it is important for the pump to be
lifted in and out.
f- Caution: If there is any doubt about the safety of the pump, do not use it.
4.1- Unpacking
4.1.1- Check the pump
1. Remove product from its packaging and check that product and accessories are not damaged.
2. Check all of the rated values on the rating plate of the pump whether or not matching with the
motor and that the pump is whether in good condition.
3. Before installation, check on the nameplate of the pump whether in accordance with the demands
of application conditions
4. Check that the shaft of the pump can rotate freely.
4.1.2- Check the motor
1. Firstly check on the name plate that the model, power (HP or kW), voltage, phase and frequency,
meet with your requirements.
2. Check the motor cable whether it is fastened properly and in good condition.
3. Use a DC mega-ohm-meter with 500 or 1000 volt-ampere to measure the insulated-resistance for
each motor cable to the base plate of motor.
The insulated-resistance should be 20 mega-ohm at lowest which is for the motor but not for the
cable.
4. Take note of the motor model, power (HP or kW), voltage, date code and serial number in a
recording sheet for future reference.
4.2- Well or installation location conditions
1. The well, where you intend to install the deep well submersible pump, should:
- be a straight well,
- keep a certain gap between the biggest outer-diameter of the pump and the inner wall of the well.
Make sure that when the pump is operating at the stipulated depth, it must not touch the walls of the
well.
2. Fit a steel pipe or a hard rubber pipe to the outlet connector (6) and fixed by a hoop tightly.
Fix the hanging rope in hanging ring (7-grommets) and prepare to hang up the pump.
NOTE: it is strictly forbidden to use power cable as hanging rope.
The submerged depth of the pump cannot exceed more than 15 meters and the distance from bottom
should be over 20cm.
It is recommended to install a dirt-stopping grid around the pump to prevent foreign materials, such
as water weeds, block the filter net, and influence the pump normal operation.
3. The motor should be kept sufficiently cool.
The well should provide with enough water quantity, to ensure max flow which is stipulated on the
rating plate
If the condition and structure of the well cannot ensure the stipulated quantity of water, the
temperature of water in well may exceed 40 °C (104F), you should reduce the load of motor or
increase the gush quantity to prevent over heat of motor.
4. The installation of a non-return valve on the delivery pipe is not required as one is already
incorporated inside the pump.
5. Install probes which will cut off the pump power supply before the water level drops to the level
