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.
