Page 3 Read the precautions in this This appliance is filled with manual carefully before R32. operating the unit. Keep this manual where the user can easily find it. WARNING: Seek assistance from your dealer or qualified personnel for the installation of your air conditioner. Attempting to install it yourself could lead to risks such as water leakage, electric shocks, fire, or explosion.
Page 4 CAUTION Avoid installing the air conditioner in areas prone to flammable gas leakage to prevent fire hazards. Ensure proper tightening of the flare nut using specified methods like a torque wrench to prevent cracking and refrigerant leakage. Take measures to prevent small animals from seeking shelter in the outdoor unit to avoid electrical malfunctions or fire risks.
Page 5 Installation Instructions Installation Precautions WARNING! Ensure that the room area where the R32 refrigerant air conditioner is installed meets the minimum requirement specified in the table below to prevent safety issues arising from refrigerant leakage. Once the horn mouth of connecting lines is fastened, it should not be reused to maintain air tightness.

Page 11 Maintenance Instructions Maintenance Precautions Precautions • Maintenance involving welding of refrigeration pipelines or components within the R32 refrigerant air conditioner system should never be conducted at the user's site. • Tasks necessitating extensive disassembly and bending operations on the heat exchanger, such as replacing the outdoor unit chassis or fully disassembling the condenser, are strictly prohibited from being performed at the user's site.
Page 12 Maintenance Instructions • The ventilator and other electrical equipment at the maintenance site must be securely fixed with standardized pipe routing. Temporary wires and sockets are strictly prohibited at the maintenance site. Leak Detection Methods • The area where refrigerant leakage is checked must be free from potential ignition sources. Avoid using halogen probes or detectors with open flames for leak detection.
Page 13 Maintenance Instructions • Prior to any maintenance, perform leak detection and inspect the grounding reliability of the air conditioner to ensure no leaks and reliable grounding. • If the service of the air conditioner may exceed the allowable voltage and current limits, do not add any inductance or capacitance to the circuit.
Page 14 Scrapping and Recovery Note: Before scrapping, the technician shall be completely familiar with the equipment and all its features. The safe recovery of refrigerant is recommended. In case the refrigerant recovered needs to be reused, before which the sample of refrigerant and oil shall be analyzed. The power supply required shall be guaranteed before tests.
Page 15 Indoor/Outdoor Unit Installation Drawings The models adopt HFC free refrigerant R32 For installation of the indoor units, refer to the installation manual which was provided with the units. (The diagram shows a wall-mounted indoor unit.) Attention must be paid to the rising up of drain hose more than 15cm more than...
Page 16 Safety Precautions fire or explosion. Place the unit on a stable, level surface capable of withstanding its weight to prevent tipping over or falling, which could cause injury. Only use specified cables for wiring. - Securely connect each cable, ensuring they are not straining the terminals.
Page 17 Safety Precautions WARNING CAUTION Open the window and well ventilated the room In such a case, continuing to use the conditioner may damage it and pose risks of electrical shock or fire hazards.
Page 18 Safety Precautions Open the window and well ventilated the room explosion-proof fuse Install a explosion-proof breaker for current leakage at the power source to avoid the risk of the electric shock. Lack of a breaker for current leakage can pose risks of electric shock, fire, or explosion.

Page 24 Installation Procedure After completing the connection of the refrigerant pipe, an air tightness test should be conducted. • Use a nitrogen tank to pressurize according to the pipe connection mode as shown in the diagram. • Ensure that both the gas and liquid valves are closed. Before pressurizing to prevent nitrogen from entering the outdoor unit's circulation system, tighten the valve rods (both gas and liquid valve rods).
Page 25 Installation Procedure Remove the cap from the service port of the 3-way valve and the caps from the valve rod for both the 2-way and 3-way valves. Connect the service port to the low- pressure port on the gauge manifold using the appropriate hose projection. Connect the center projection of the charge hose from the gauge manifold to the vacuum pump.
