Do’s
Don’ts
Foot valve is not required. However, a quality foot valve
with strainer can be used to prevent rags, leaves, etc.
from being sucked into the pump and thereby clogging
the pump
Do not install the pump with high static suction lift
Ensure leak proof joints on the suction side to prevent
air entry and therefore loss of priming
Do not use piping smaller than what is mentioned on
the nameplate
Use as few joints as possible on the suction line
Provide sufficient space around the pump set so as to
ensure proper airflow
After installation, prime the pump
Restrict the number of joints on the cable. More the
number of cable joints, more will be the voltage drop
Rotate the shaft to ensure that pump is not jammed
Do not place the foot valve right near the bottom of
the well / tank / river as there is possibility for solids
to be entrained with water
Ensure proper earthing is provided
Do not over tighten the gland. Tighten so that at
least 20 drops of water continuously flows past the
gland, thereby ensuring cooling of the shaft
Mount the pumpset on a level foundation
Do not restrict the space behind the cooling cover as
this will obstruct the flow of air required for cooling
of the motor
Check the direction of rotation of the pumpset matches
the arrow mark cast on the casing
Do not use to pump corrosive and flammable liquids
Rubber gaskets assembled on the pump do not have a
central hole. Cut out the central hole and re-install
Do not earth to a water line or gas line
Check all fasteners are tight
Do not use undersized electric cables between Pump
and Starter Panel. Factor in low-voltage usage
Motor portion of pump set is IP44 protected. Provide
protection from rain
Do not cover the product as this will prevent effective
cooling of the motor
Use a starter with Inbuilt Single-phase Preventer,
Overload protection and High-Voltage and Low-Voltage
protection for three phase
Do not keep the pump suction tapering down towards
the pump suction to prevent air lock
