Important

Before installation

1. Check the water supply pressure

„

z

The water supply pressure is from 0.05 to 1.0MPa. Please use it within this pressure range.

„

z

When the water supply pressure exceeds 1.0MPa, please use the reducing valve to reduce the 

pressure to 0.2MPa.  

We suggest you use the water pressure of about 0.2MPa, which is more comfortable during use.

„

z

 

The cold water supply pressure must be higher than or equal to the hot water supply pressure.

2. Check the hot water supply temperature

„

z

To avoid scalding due to mis-operation, the hot water supply temperature should not exceed 85°C.

3. For layout of pipes and lines

„

z

Too long hot water pipes from the water heater may cause heat loss. Please calculate the shortest 

distance to install the hot water pipes and wrap them with thermal insulation materials.

4. Others

„

z

Please try not to damage the surface of the sensor.

„

z

Aqua-auto is only used indoors. Please do not install it outdoors.

„

z

Converters or other machines using infrared rays may cause misoperation.

„

z

Because this product is checked for water inlet before packaging, there may be water in this 

product, and it is not a problem.

„

z

When it is necessary to use drainage components, angle valves for water supply, components to 

install reversed hooks, brackets, frames, etc., matching the earthenware installed, please confirm 

related construction materials and purchase them separately.
