My HP turns OFF and ON. What is wrong?
The most common reason for the HP60 to cycle on and off is overheating due to backpressure on the system. This is a very powerful system; you need to have at least 40 air openings at all times. If you have a newer system with pressure relief valves, they will help reduce the backpressure on the system. If you do not have pressure relief valves, please purchase the PRV Upgrade kit to prevent this from happening to the HP. There is an inline filter that can be either dirty or clogged. Clean the inline filter on the AIR IN Main Hose (clear top) and the screen located on the AIR IN Pipe (mounted on the HP60 itself). The temperature may be too hot where the HP60 is located. If the temperature is above 100 degrees, move it out of the area.
