2.1.1 The exhaust gas can be exhausted directly to atmosphere, or can be recovered to a lower pressure gas system. If vented directly to atmosphere, CheckPoint supplies the pump with a muffler to reduce exhaust noise. 2.1.2 If recovering the exhaust gas, connect the gas recovery line from the process to the open 1/2” tubing connector on the injector. - Page 9 Operating Manual 3.1.1.4 Now ensure that the CheckPoint pump is running. Take note of the level of chemical in the gauge using the appropriate scale for the volume units you want to measure the pump’s output in. Usually the gauge will show liters on one scale and quarts or gallons on the other.
