Safety devices
The safety devices are designed to protect the user and may not be de-
activated or repurposed.
Relief valve
■ If the hand spray gun is closed, the relief valve opens and the high-pres-
sure pump routes the water back to the pump suction side. This prevents
the permissible working pressure from being exceeded.
■ The relief valve is set and sealed at the factory. It may only be adjusted
by the customer service.
Safety valve
The safety valve opens if the permissible maximum allowable working
pressure is exceeded (see technical specifications); the water flows out.
The safety valve is set and sealed at the factory. It may only be adjusted
by the customer service.
Thermal valve
The thermal valve protects the high-pressure pump from impermissible
warming in circulation operation if the hand spray gun is closed.
The thermal valve opens if the maximum permissible temperature of 68°C
is exceeded and drains the hot water.
