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 nameplate
Use a check valve fitted on the delivery line when the Single Phase Openwell submersible has
high delivery heads
Use a power cable without joints from the Single Phase Openwell submersible to the control
panel. It is not recommended to use a power cable with large number of joints as this can result
in a significant voltage drop
If used in a well, check the level of silt at the bottom of the well. De-silt if necessary
Check the availability of Single Phase power
Check if the motor is completely filled with water. Top up if required with pure drinking water
It is recommended to assemble the Single Phase Openwell submersible on a fairly level base to
prevent the pump and piping from getting stressed
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
While installing the Openwell Submersible, ensure the Openwell Submersible is not subject to
shock loads which can damage the Openwell Submersible parts
Use the services of a professional and trained mechanic with experience in erecting
Openwell submersible
Ensure proper safety precautions during installation
Use the eye bolts / lifting lugs for lifting / lowering the Single Phase Openwell submersible using
appropriate equipment
