Page 2 Note 1. Please read the instruction manual carefully before installation or operation. 2. The heat pump must be installed by a professional installer. 3. Please follow the instruction manual strictly when installing the heat pump 4. If any update on the product, this instruction manual is subject to change without notice 5.
Page 3 User Instructions 2. Make sure that the leakage protection switch Please use an electrical leakage switch, is securely connected. If the wiring is not secure, otherwise, there may be electric shock, fire, etc. it may cause electric shock, heat, or fire. Test Button 3.
Page 4 Please read the labels on the machine carefully. If abnormal conditions such as abnormal noise, odor, smoke, temperature rise, electric leakage, fire, etc. are found during use, please cut off the power immediately and contact our local customer service center or dealer in time to repair it. Contact the local fire and emergency department immediately if necessary.
Page 5 for a long time, it is recommended that the user drain the water out of the water system and disconnect the power supply. 8) Please perform regular maintenance on the machine as required by the instructions to ensure the device is in good operating condition. 2.
Page 6 ensure the technician is aware of potentially flammable atmospheres. Ensure that the leak detection equipment being used is suitable for use with flammable refrigerants, i.e. non- sparking, adequately sealed or intrinsically safe. v. Presence of fire extinguisher If any hot work is to be conducted on the refrigeration equipment or any associated parts, appropriate fire extinguishing equipment shall be available to hand.
Page 7 7) Repairs sealed components: a) During repairs to sealed components, all electrical supplies shall be disconnected from the equipment being worked upon prior to any removal of sealed covers, etc. If it is absolutely necessary to have an electrical supply to equipment during servicing, then a permanently operating form of leak detection shall be located at the most critical point to warn of a potentially hazardous situation.
Page 8 The refrigerant charge shall be recovered into the correct recovery cylinders. The system shall be “flushed” with OFN to render the unit safe. This process may need to be repeated several times. Compressed air or oxygen shall not be used for this task. Flushing shall be achieved by breaking the vacuum in the system with OFN and continuing to fill until the working pressure is achieved, then venting to the atmosphere, and finally pulling down to a vacuum.
Page 9 The label shall be dated and signed. Ensure that there are labels on the equipment stating the equipment contains flammable refrigerant. 16) Recovery When removing refrigerants from a system, either for servicing or decommissioning, it is recommended good practice that all refrigerants are removed safely. When transferring refrigerant into cylinders, ensure that only appropriate refrigerant recovery cylinders are employed.

Heat Pump Installation 2.1 The machine installation space meets the following schematic requirements to ensure regular air circulation and maintenance; 2.2 The location of the machine should be kept away from heat, steam, or flammable gases; 2.3 Do not install the machine in places with strong wind or dust; 2.4 Do not install the machine where it is often passed through the air suction side and air exhaust side;...
Page 21 If installed on a wall or a roof, the bracket must be firmly fixed to prevent damage caused by an earthquake or strong wind; The positioning dimension of the outdoor unit installation base is 810*394mm. It is required to install four-position foot bolts with a diameter of 10mm—at the bottom of the installation of the outdoor unit.
Page 22 Remark 1. The same piping design is allowed to distribute the water evenly. 2. The system must be equipped with an automatic water supply valve, and the highest point of the water system must be equipped with an automatic pressure relief valve; 3.
Page 23 5. Selection and Installation of Water System Accessories Selection Of Circulating Pump 5.1.1 The machine must be installed with a circulating pump to be used. The heat pump provides the power port of the circulating pump (single-phase power supply). Please refer to the circuit diagram for wiring.

Page 30 Commissioning and Maintenance 1. Precautions Before Commissioning Is the machine adequately installed? Is the wiring and pipe correct? Whether the water pipelines are empty or not? Whether the heat insulation has been perfected? Is the ground wire connected reliably? Whether the power supply voltage matches the rated voltage of the machine? Is there any obstacle in the air inlet and outlet of the machine? Is the safety valve installed correctly? Whether the leakage protector can operate effectively?
Page 31 Power Outage If there is a power outage during operation, the machine will stop running. Before the power outage, the controller automatically memories the ON/OFF status of the device. After re- powering, the controller will send an ON/OFF signal to the device according to the state of memory before the power outage to ensure that the device recovers from the previous status from abnormal power failure.
