is released, the engine continues to run at
zero speed. The water thus circulates with-
in the pump and gets heated. When the cyl-
inder head at the pump has reached the
maximum permissible tempertaure (80 °C),
the therm-valve on the pump opens and
lets out the hot water into the open.

pressed water from the water supply pipes:

Pull the lever of the hand spray gun for
2 - 3 minutes so that the circulating wa-
ter cools down the cylinder head.
