ALIGNMENT AND INSTALLATION OF PUMP.The shaft alignment for pump
and electric motor shall be limited to 0.05mm TIR. and 1 degree
angular error.

CAUTIONS FOR STARTING.Start up the pump under No-Load condition
and repeat to start and stop the motor several times to extract the
air from inside of the pump and piping. Then keep a 10 minutes
continuous running for a better de-airing.
PEAK-PRESSURE.The peak pressure is 140kg/cm2 for code *2 &
*3, and 210kg/cm2 for A4 & A5.
