If thedump valve remains closedcheck the gun and air hose forleaks, if no leaks are found,unplug the flow switch fromthe control board. If the dumpvalve opens, replace flowsensor kit 234232. If the dumpvalve still remains closedcheck the dump valve for ablockage and the Mac AirValve for a stuck spool valve.Mac Air Valve15B683No Coil Voltage.

Engine PowerNotUsed1030FC <strong>Electrical</strong> and Air Ladder DiagramSpraying Mode:In order to spray the control board must senses 30psi or higher and the rotary switch must be in oneof the 3 settings Low/Med./High. When the spray gun is triggered the flow switch will close,sending a signal to the control board. The control board will then send voltage out to the clutchfield to start the pump. At the same time voltage will be sent to the Mac air valve coil. The coil willclose the air valve changing the direction of the air flow to the dump valve. Air will now travelthrough the blue hose to the back of the dump valve forcing it closed .When this occurs thematerial will be forced out through the material hose.Clutch CoilThermistorWht. Com.Blk.
