outlet pipes of the coil pipes of the NetCol8000.
● Connect the water inlet and outlet pipes of the NetCol8000 using thread
connectors. When connecting the water pipe, do not exert excessive force to
prevent damage to the coil pipe. (When connecting the pipes provided with the
NetCol8000, use two pipe wrenches or chain pliers.)

Use DN20 PPR pipes or stainless steel pipes and connectors G with 3/4 inch
external threads onsite to prepare water inlet pipes. If galvanized steel pipes are
used, stainless steel connectors must be used to ensure sealing.
