Figure 8 Diagram（Single unit for reference）
● The one-way valve is suggested for each unit, to prevent the water back flow.
● The system can be combined with multiple units, but should be controlled by each unit
independently.
● Regarding the installation of backup pump, maintenance valve and temperature measure point,
please consider it yourself.
● All pipes and valves of the unit need the heat preservation.
5.2.3 Selection of the water pipes
The swimming pool heat pump adopt the titanium heat ex-changer, can connect the swimming pool
directly, but must install a water filtration equipment before water go into heat pump, the filter meshes is
about 40 meshes.
Main pipe diameter selection of the parallel connected multiple units (example)
● The pipe press and flow rate should be calculated before the diameter selection, the range of
pressure drop is 0.3
〜
0.5 kgf/cm2(3
〜
5m
）
the range of head pipe flow rate is 1 .2
〜
2. 5 m/s.
● The hydraulic calculation should be made after the selection of pipe diameter, if the resistance is
more than pump head, then need to choose a more power pump, or choose a bigger pipe.
