two minutes at a time. Pump operates in
bypass mode when spray gun trigger is not
pressed. When the temperature inside the
pump rises too high the thermal relief valve (T)
will open and release a gush of water in an
effort to lower the temperature inside the pump. The thermal
relief valve will then close. If pump is left in bypass mode for
more than two minutes internal components of the pump can
be damaged.
