GENERAL INSTALLATION PRECAUTIONS

Do not use this pump for oil or toxic, acetic, corrosive and inflammable
liquids. Pumping inflammable liquids could cause explosion.

Do not use cable for lifting the pump. Do not damage, fold, twist, make
alterations or bundle the cable.
The rope or chain for suspending the pump during installation that
accommodates the weight of the pump should be thick and make sure, that
does not get twisted. Damages in rope or chain can cause the pump to fall.
For better performance avoid flexible hose and use rigid pipe. Excessive
bending of the discharge pipe could obstruct the water flow, reduce the
discharge volume or clog the pipe with mud, which could affect pump
performance. Route the pipe as straight as possible.
Use a power supply cable that has sufficient rating and has been exclusively
provided for the pump. Sharing power cables with other equipments, can
lead to abnormal heat at the plug outlet and it can lead to fire.
Provide proper earthing. Do not connect the earthing wire to water pipe,
lightening rod or telephone earth wire. Improper earthing could cause
electrical shock.
To verify the insulation of the motor, use megger. Insulation resistance should
be 20MΩ minimum.
It is recommended to use an Earth Leakage Circuit Breaker (ELCB) to connect
the pump with main supply for safe operation.
Do not place the pump in the sludge, as it may lead to chocking of the pump
impeller.
