What water pressure is required for the appliance, and what should I do if pressure is too high?

The water pressure in the water supply system must be at least 29 psi (200 kPa) and a maximum of 116 psi (800 kPa). If the water pressure exceeds the maximum value, a pressure-reducing valve must be installed between the drinking water connection and the appliance's hose set. Insufficient or excessive water pressure may impair the functioning of the appliance. (Page 7)
