Water pressure must be between 50 kPa and 800 kPa (0.5‒8.0 kgf/cm²). If the water pressure is more than 800 kPa, a decompression device should be installed.
Periodically check the condition of the water supply hose and replace the water supply hose if necessary.
Do not overtighten the water supply hose or use mechanical devices to tighten onto the inlet valves.
No further backflow protection required for connection to the water inlet.
