Fig. 19 Change of Connections for Normal Pump Performance
WARNING :
CHECK THE PUMP TO REDUCE THE TORQUE PRODUCED BY
A LARGE SIZED PUMP.
(2) If the pressure gauge or compound pressure gauge is not installed on
discharge pipe.
If checks of the rotating direction of the pump in the water as described above
cannot be performed, proceed as follows.
Lay the pump on the ground. Turn switch on and off instantaneously, and
check visually the rotation direction through the discharge bore of the pump.
The rotating direction of the pump should be clockwise when viewed form
above.
CAUTION :
SINCE THE STARTING TORQUE ON LARGE PUMPS CAN BE
POWERFUL, THE PUMP MUST BE SUPPORTED.
DANGER :
DURING CHECKING THE DIRECTION OF ROTATION, DO NOT
TOUCH ROTATING PARTS OF THE PUMP. KEEP HANDS, HAIR AND TOOLS
AWAY FROM ROTATING PARTS TO PREVENT SERIOUS ACCIDENTS.
