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 insula-
tion.
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 se-
lected 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.
