Check the rotor for clockwise rotation (facing belt/chainguard)Make certain that no foreign objects, such as tools, have fallen into the conveyors or airlock during installation.JETPULSEThe pressure gauge on the header pipe should read between 80 and 95 PSIG. Initiate the pulse cycle. Onediaphragm valve will open at a time to pulse one row of bags. The pressure in the header pipe must build back up too 80-95 PSIG before the next pulse. If the pressure is too low between pulses, adjust the timer so that there is more timebetween pulses.Check that each diaphragm valve closes after every pulse and be sure there are no leaks in any of the piping.AIRCOMPRESSORReference Ingersall-Rand manual and drawing.Check crankcase oil level, compressor rotation, and prime condensate trap.
