Water supply pressure must be between 50 kPa and 800 kPa (0.5 - 8.0 kgf / cm2). If the water supply pressure is more than 800 kPa, a pressure reducing device should be installed.
Do not overtighten the water inlet hose when connecting it to the valve.
Periodically check the condition of the hose and replace the hose if necessary.
The water supply hose supplied may vary from country to country. Make sure to connect the blue supply hose to the COLD water tap, and the orange supply hose to the HOT water tap.
