Chapter Ⅰ Product Introduction（4. Optional Fittings）

⑤Circulating water flow means the rated flow during the heating operation. When selecting
the water pump model, it shall refer to the flow after overcoming the water resistance, that is, the
flow of corresponding delivery lift, rather than the maximum flow labeled in the nameplate of water
pump.
⑥The listed water resistance refers to the water resistance under rated working conditions. If
the ambient temperature and water inlet temperature are different, unit‟s hot water output will be
changed accordingly, and the water resistance may be different from the listed value.
⑦If the specification is changed due to the product improvement, please refer to the
nameplate.
⑧The system reliability and the different water temperature requirement under different water
temperature are considered for this product and limit the maximum water tank temperature for
stop operation.
The curve is as below:
