Chapter 2: System Installation 1. Turn the red-handled operating lever located on the side of the pressure switch to the “Off” position. 2. Connect the BLACK alligator clip on the end of the power cable to the NEGATIVE terminal of the battery. 3. -
Page 8: Chapter 3: System Operation
Chapter 3: System Operation During actual operating time, the compressor uses 22 amp/hrs of current. (160 amps required to start a momentarily stopped rotor) Therefore, it is recommended that a marine deep cycle or vehicle battery be used to operate the unit. The automatic operation of the unit from the pressure switch should minimize the actual power consumed during sampling of wells. -
Page 9: Low Flow Purging And Sampling
Low Flow Purging and Sampling The Model 94000 12 vdc compressor has been designed for Low Flow purging and sampling. The unit will operate most efficiently where long pump cycles are used. If your target flow rate is 200 mls/minute, use 2 x 30 second pump cycles per minute. -
