Dry Run Pump Protector

These flow activated models use a state-of-the-art PCB to monitor a minimum flow to stop the pump motor. They are adjustable for flow rates from 0.1 gpm to 6.0 gpm. These units are factory set for 0.1 gpm. If used for a multiple bearing sump pump, the unit must be reset to a higher set point per the pump's operating instructions. These models are plastic enclosed, include 8 feet of extension cable and mounting bracket for 56, 140 and 180 "C" face motor frames. Select a model for either factory or field installation. When used with magnetic H-O-A starter: In the AUTO position, the DRI-STOP will allow the motor to start if the seal/bearing water flow is 6 GPH or higher. The HAND position should not be wired into the control circuit. Note that a push button magnetic starter may be used instead of the recommended H-O-A. For motor starters, see Bulletin A-103. CAUTION !! In the AUTOMATIC mode, the motor will come on automatically when the water supply is turned on.
