3.5.1 Installation Requirements of Water System Piping
(1) The design and construction of the water system must meet the requirements
of the local plumbing design specifications and relevant standards.
(2) For an appliance intended to be permanently connected to the water mains
and not connected by a hose set.
(3) The water pipe connecting parts must be sealed with raw tape to prevent
water leakage.
(4) The water inlet and outlet connection parts of each pipeline shall be pasted
with water inlet and outlet signs to avoid connection errors.
(5) The water pipe installation shall be arranged horizontally and vertically, and
the pipe layout shall be reasonable to minimize bending, reducing the
resistance loss of the water system.
(6) All valves must be installed strictly, and the installation sequence must be
consistent with the unit installation diagram.
(7) The pipeline shall be arranged in a centralized way. The water outlet of the unit
shall not be too far from the hot water use point, and there shall be a drainage
floor drain nearby.

installed before the water pump to prevent the blockage of the water-side heat
