3.9 Safety device (bypass valve)
On the pressure side, the high-pressure cooling pump has a bypass valve. This valve leads the water back to
the suction side of the pump if one or more nozzles are clogged.
Never mount a ball plug valve etc., which is capable of shutting off the pump or the nozzles.
The water in the pump is heated and the safety valve opens if more than 80 % of the water (pump capac-
ity) is bypassing.
