Injecting into pressurized lines up to 30 PSI is possible without special considerations. The SR-4000 and SR-6000 can also be set on a continuous setting and cycled by an automatic controller. Risk of chemical burns and explosion.
The controls described in this manual refer to the compo- nents on the Printed Circuit Assembly (PCA). The PCA is mounted on the inside of the door of the SR-4000/ SR-6000. To determine the location of these controls on the PCA, please refer to Figure 4.
Determine the injections per day required and the duration time of each injection by using the chart on Page 4. EXAMPLE 1: 6 doses per day at 25 seconds each will de- liver 15 ounces per day. EXAMPLE 2: 8 doses per day at 60 seconds each will de- liver 48 ounces per day.
Calibration may be required to determine actual flow with each installation. Calibration The SR-4000/SR-6000 have a nominal flow rate of 6 fluid ounces per minute per pump (@60 RPM). When pumping into an open or non-pressurized location, the actual pump flow can be measured at the output point by pumping ac- tual product into a container of a known volume.
Pump Speed Adjustment The pump speed potentiometer allows for speed adjust- ment. The pump is factory set with the knob turned as far as it will go clockwise ( ) for maximum speed (60 RPM). Adjust the interval and duration settings, rather than the pump speed setting, to meet daily requirements.
