Arrangement for Installation
General Installation Precautions
Open the packaging and note down the serial number and model for future reference
Ensure all fasteners are tightened properly
Use prescribed pipe sizes as mentioned on the product name plate
To prevent the motor from getting exposed during pumping, ensure the suction strainer is fitted
above the level of the motor. This is done by fitting one end of a bend to the pump suction flange
and the strainer to the other end of the bend, thereby ensuring that the level does not fall below
the strainer
Use a Check valve fitted on the delivery line when the Openwell Submersibles has high
delivery heads
Use a power cable, without joints, from the Openwell Submersibles to the starter. It is not
recommended to use a power cable with large number of joints as this can result in a significant
voltage drop
Check the level of silt at the bottom of the well. De-silt if necessary
Check the availability of three phase power
Ensure availability of a starter with inbuilt single phase preventer, overload protection and high
voltage and low voltage protection
Fill the motor with water pure drinking water before installation
In case of rapid rise of water levels during the rainy season, provide a throttle valve in the
delivery pipe line
While installing the Openwell Submersibles , ensure the Openwell Submersibles is not subject to
shock loads which can damage the Openwell Submersibles parts
Use the services of a professional and trained mechanic with experience in erecting Openwell
Submersibles
Ensure proper safety during installation
Ensure that the bottom of the well / water source is fairly level before erection of the Openwell
Submersibles
