5.Water System Connection

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.
(8) All water system pipelines, valves and pipe joints must be laid with insulation layer to reduce heat
loss. Common insulation materials include soft polyethylene foam (PEF), glass wool, rubber
insulation cotton, and the thickness of insulation layer shall be ≥ 30 mm.
5.2 Water Supply Pipeline Connection
The heat pump unit is equipped with two pipe joints (PVC Ф50 mm), which are used to connect the
pipeline from the filter pump and the water outlet pipeline, and connect to the circulating hot water
system of the swimming pool.
To guarantee the safe usage of unit, a reduction valve should be installed in the water inlet pipe if
the water inlet pressure exceeds 0.5MPa.
Note: The water entering the unit must be the water passing through the swimming pool filter to
prevent the impurities from blocking the heat exchanger of the heat pump unit, and the swimming pool
disinfection device must be installed at the downstream of the water outlet pipeline of the heat pump unit
to prevent the chemical composition of the disinfection device from affecting the heat exchanger of the
unit.
