5.5 Thermal Relief Valve:
If the machine is left running without the trigger gun being engaged for more than two minutes, the water
temperature will rise to a dangerous level and damage the internal components of the pump. In an effort to
prevent damage, pumps are equipped with a thermal relief valve. This valve will open when the temperature
rises too high. This valve will then release a gush of water in an effort to lower the temperature inside the
pump. Immediately after released the water, the valve will close.
5.6 THE UNLOADER VALVE
The machine is installed with one unloader, it can redirect the flow back to the inlet side of the pump when
