To check system operation, installation INSTALLATION of vacuum/pressure gauges in the (SEE FIGURE 1) suction and discharge lines is recommended. 1. Pump installation site should provide easy Keep suction lines short and straight to access for routine maintenance and where minimize friction loss to the pump. -
