Aquamist 160psi Pump
Aquamist 160psi pump as supplied with HFS-2/3/4/6 systems. Nominally flows 2000cc, but the FAV will limit flow to 1300-1500cc. Pressure screw on the front of the pump will increase dead head pressure to 180psi. This should only be done when running close to 1500cc of jetting to ensure proper pressure at high flow rates. Allen screw is 1/16″, turn clockwise until a loud click is heard to set maximum pressure. Setting to max pressure may wear pump head faster than normal.
