Changing Times - Model GPM - Liquid Applicator - Brochure

Pressure is adjusted by changing the position of the yellow valve handle that is located just above the pump motor. Changing the position of that valve setting will increase the volume of liquid returning to the tank and increase agitation in the tank thereby reducing the pressure or the inverse. The agitation decreases as the pressure increases. Operation in a range of 10 to 40 PSI will keep good agitation in the tank and produce even product flow.
