Safety

· Tempering valves must only be installed by a licensed plumber.

· A minimum temperature differential of 10°C is required between the hot water inlet

and the mixed water outlet to ensure correct operation of the thermal shutoff feature.

· Water temperatures higher than 50°C can endanger people.

· Ensure that the valve is supported and that the connecting pipework is not overstressed as

breakages can cause harm to people and/or water damage to property.

· In the case of highly aggressive water, in accordance with the current legislation, treat the

water before it enters the tempering valve. This will avoid damage to the valve.

· If the tempering valve is not installed, commissioned and maintained properly, according to

the instructions contained in this manual, it may not operate correctly and may endanger the user.

Leave this manual for the user.
