 Open the master air valve from the compressor.
 Open the dispensing valve into a grounded metal waste container, making firm metal-to-metal
contact between the container and valve. Open the bleed-type master air valve and open the
pump air regulator slowly, just until the pump is running. When the pump is primed and all air has
been pushed out of the lines, close the dispense valve.
 If you have more than one pump, repeat this procedure for each pump.
 Set the air pressure to each pump at the lowest pressure needed to achieve desired results.
 Relieve pressure before you check or service any system equipment.
