(2)  If the pressure gauge or compound pressure gauge is not installed on the 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 from top of motor.   

 

 

 

     CAUTION:

 SINCE THE STARTING TORQUE ON LARGE PUMPS CAN BE POWERFUL, 

 

THE PUMP MUST BE PROPERLY SUPPORTED. 

 

 

 

DANGER: 

DURING  CHECKING THE DIRECTION OF ROTATION, DO NOT TOUCH 

 

ROTATING PARTS OF THE PUMP. KEEP HANDS, FEET, LIMBS, HAIR AND TOOLS AWAY 

 

FROM ROTATING PARTS TO PREVENT SERIOUS ACCIDENTS.
