5-6 Determining Flow Rate
To determine flow:
1.Close the gauge cock leading to the pump suction side and open the gauge cock leading to the pump discharge.
2.Start the pump and make note of the discharge pressure in psi (kPa/bars).
3.Check the pump curve for the appropriate horsepower pump at the discharge pressure psi.
4.Project this point down to find the flow in gpm (lpm).
5.Process pumps can be left wide open if running amps are below full load amps.
5-7 Shutdown
1.Ready process and related equipment for shut down.
2.Donot turn off main power until chiller completes the shut- down sequence (approximately 2 minutes).
3.Close the water make up valve.
4.If the system is to be drained, open the 2” drain valve.
