Water loop connection
Please pay attention to the below points when connecting the water loop pipe:
1. Try to reduce the water loop resistance
2. Make sure there is nothing in the pipe and the water loop is smooth, check the pipe carefully to
see if there is any leak, and then pack the pipe with the insulation.
3. Install the one way valve and safety valve in the water circulation system.
4. The nominal pipe wide of the field- installed sanitary installations must be selected on the basis of
the available water pressure and the expected pressure drop within the piping system.
5. The water pipes may be of the flexible type. To prevent corrosion damage, make sure that the
materials used in the piping system are compatible.
6. When installing the pipe-work on the customers’ site, any contamination of the piping system
must be avoided.
