13. Do’s and don’ts
Do’s
Don’ts
Use a quality foot valve with strainer
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 pumpset so as to
ensure proper airflow
After installation, prime the pump
Restrict the number of joints on the cable. More the
cable joints, more will be the voltage drop
Rotate the shaft to ensure that pump is not jammed
Do not place the strainer right near the bottom of
the well / tank as there is possibility for solids to be
entrained with water
Ensure proper earthing is provided
Do not restrict the space behind the cooling cover as
this will obstruct the flow of air required for cooling
of the motor
Mount the pumpset on a level foundation / surface
Do not use to pump corrosive and flammable liquids
While powering up the pumpset, ensure the direction of
rotation of the shaft, looking from the cooling fan side,
is clockwise
Do not earth to a water line or gas line
Rubber gaskets assembled on the pumpset do not have
a central hole. Cut out the central hole and reinstall
Do not cover the product as this will prevent effective
cooling of the motor
Check all fasteners are tight
Do not keep the pump suction tapering down towards
the pump suction to prevent air lock
Motor portion of pumpset is IP44 protected. Provide
protection from rain
Do not operate the pump at shut-off conditions
Operate the pump in the specified operating head
range
As far as possible, avoid the usage of elbows. Prefer
long radius bends
