Back flow pressure regulator adjustment
The back pressure regulator can be adjusted to control the pressure,
thus allowing the flow output from the nozzle. If the unit is not flowing
it could be encountering pressure lock. In this situation, during priming
mode, rotate the adjustment pin counter clockwise until pin is level
with black surface. Once liquid starts to disperse from the nozzle, start
to screw the pin clockwise, this will then raise the pressure and begin
to allow the nozzle to disperse correctly.
