Page 2: Safety Precaution
Safety precaution To avoid electrical shock, make sure to disconnect power supply 1minute or more before operating the electrical part. Even after 1minute, always measure the voltage at the terminals of main circuit capacitors or electrical parts and, before touching, make sure that those voltages are lower than the safety voltage. - Page 3 To know the product from exterior Electric box Air inlet Air outlet Water outlet Cable hole Water inlet High pressure gauge Low pressure gauge...

Page 9: Introduction Of The System
Introduction of the system 1. Hot water tank temp sensor (T1) The sensor should be put in the sensor tube which is installed in hot water tank. 2. Floor heating water temp sensor (T2) 2.1 Floor heating temp sensor has been installed on the inlet water pipe inside heat pump before leave factory. - Page 10 Introduction of the system 5. Three way valve (3WV): 5.1 Three way valve is controlled by heat pump controller. 5.2 When room linkage switch is connected: hot water is priority, means if both hot water side and floor heating side need be heated, the three way valve will change to hot water side, until hot water tank reach preset temp, then the valve will change to floor heating side.
- Page 11 Introduction of the system 8. About hot water tank 8.1 Because the three way valve, a coil heat exchanger must be installed in hot water tank. Otherwise, the sanitary hot water will be mixed with floor heating water. 8.2 The coil heat exchanger capacity should be about 18KW. And the inner diameter of coil should be ≥DN25.
- Page 12 Heat pump installation notes The heat pump must be installed in open space. Normally is installed on the roof of house. The unit should be placed in dry and well-ventilated environment. If the environment is humid, electronic components may get corroded or short circuit. Heat pump mustn’t be installed in the environment where corrosive, volatile, or flammable liquid or gas exists.
