System Requirements
• Install a bleed-type master air valve on a pneumatic pump air supply line to relieve air trapped between this valve and
the pump after air regulator is shut off. Trapped air can cause the pump to cycle unexpectedly.
• Install a fluid drain valve between the pump and gun to relieve pressure in displacement pump, hose, and gun. Trig-
gering gun to relieve pressure may not be sufficient. See Pressure Relief Procedure, page 10.
