w Read the precautions in this manual carefully before operating the unit. This appliance is filled with R32. Keep this manual where the user can easily find it. WARNING: Ask your dealer or qualified personnel to carry out installation work.Do not attempt to install the air conditioner yourself. Improper Installation may result in water leakage, electric shocks, fire or explosion.
CAUTION : Do not install the air conditioner at any place where there is danger of flammable gas leakage. In the event of a gas leakage, build-up of gas near the air conditioner may cause a fire to break out. Tighten the flare nut according to the specified method such as with a torque wrench.If the flare nut is too tight, it may crack after prolonged use, causing refrigerant leakage. Take adequate steps to prevent the outdoor unit being used as a shelter by small animals.
Loading and Unloading/Transporting Management/Storage Requirements • 1) 2) 3) 4) 5) 6) Loading and Unloading Requirements The products shall be carefully handled during loading and unloading. Do not give impact to the indoor and outdoor units, or otherwise product damage may result. Be sure to read the safety cautions before conducting any work. Dry powder extinguishers or other suitable fire extinguishing apparatus should be equipped at the loading area.
• Safety Awareness 1. Procedures: operation shall be made as per controlled procedures to minimize the probability of risks. 2. Area: area shall be divided and isolated appropriately, and operation in an enclosed space shall be avoided. Before the refrigeration system is started or before hot working, ventilation or opening of the area shall be guaranteed. 3. Site inspection: the refrigerant shall be checked. 4.
• Electrical Safety Requirements Note: 1. The surrounding conditions (ambient temperature, direct sunlight and rainwater) shall be noticed during electrical wiring, with effective protective measures being taken. 2. Copper wire cable in line with local standards shall be used as the power line and connector wire. 3. Both the indoor unit and outdoor unit shall be reliably earthed. 4. Wiring for the outdoor unit shall be made first and then the indoor unit.
1) Fixation The support of the outdoor unit shall be fixed onto the wall surface, and then the outdoor unit shall be fixed onto the support horizontally. In case the outdoor unit is wall-mounted or roof-mounted, the support shall be firmly fixed, to avoid the damage of strong wind. 2) Installation of connecting pipes The cone of the connecting pipes shall be aligned with the conical surface of corresponding valve connector.
Relocation Procedures Inspection on system leakage prior to disassembly Safety discharge of refrigerant Inspection on operational state Safety discharge of refrigerant Refrigerant recovery by the system Cleaning of the indoor unit and connecting pipes with inert gas Disassembly Installation as required in standards Note: in case relocation is required, the joint of evaporator gas/liquid pipes of the indoor unit shall be cut off with a cutting knife.
Inspection on Maintenance Environment • Before operation, the refrigerant leaked in the room is not allowed. • The area of the room in which maintenance is made shall be in line with the nameplate. • Continuous ventilation shall be maintained during maintenance. • Open fire or high-temperature heat source higher than 548 degree which can easily give birth to open fire is not allowed inside the room within the maintenance area.
Maintenance Items Maintenance Requirements • Before the refrigeration system is operated, the circulating system shall be cleaned with nitrogen. Afterwards, the outdoor unit shall be vacuumized, the duration of which cannot be less than 30 minutes. Finally, 1.5~2.0MPa OFN shall be used for nitrogen flushing (30 seconds~1 minute), to confirm the position requiring treatment. Maintenance of the refrigeration system is only allowed after the residual gas of flammable refrigerant is removed.
Removal and Vacuumizing The maintenance or other operations of the refrigeration circuit shall be made as per conventional procedures. Moreover, the flammability of refrigerant shall also be mainly considered. The following procedures shall be followed: • Refrigerant clearing; • Pipeline purification with inert gas; • Vacuumizing; • Pipeline purification again with inert gas; • Pipeline cutting or welding. The refrigerant shall be recovered to a proper cylinder.
(5) In case the vacuum state cannot be reached, vacuumizing shall be carried out from numerous positions, to pump the refrigerant in each part of the system out; (6) It shall be guaranteed that the capacity of cylinders is sufficient before recovery; (7) The recovery equipment shall be started and operated as per the operation instructions of the manufacturer; (8) The cylinder cannot be charged too full.
Indoor/Outdoor Unit Installation Drawings The models adopt HFC free refrigerant R32.

Safety Precautions ~ WARNING • Have the unit professionally installed. Improper installation by an unqualified person may result in water leak, electric shock, or fire. • Be sure to carefully follow each step in this handbook when installing the unit. Improper installation may result in water leak, electric shock, fire or explosion.
Safety Precautions Precautions for Handling Units for Use with R32 ~ Caution Do not use the existing refrigerant piping • The old refrigerant and refrigerator oil in the existing piping contain a large amount of chlorine, which will cause the refrigerator oil in the new unit to deteriorate. • R32 is a high-pressure refrigerant, and the use of the existing piping may result in bursting. Use a vacuum pump with a reverse-flow check valve.
Safety Precautions Carefully read the following information in order to operate the air conditioner correctly. Below are listed three kinds of Safety Precautions and Suggestions . .&. WARNING Incorrect operations may result in severe consequences of death or serious injuries . .&. CAUTION NI Incorrect operations may result in injuries or machine damages; in some cases may cause serious consequences. INSTRUCTIONS: These information can ensure the correct operation of the machine.
Safety Precautions Before Installing (Relocating) the Unit or Performing Electric Work ~ Caution Ground the unit. • Do not connect the grounding on the unit to gas pipes,water pipes, lightning rods, or the grounding terminals of telephones. Improper grounding presents a risk of electric shock, smoke, fire, or the noise caused by improper grounding may cause the unit to malfunction. Do not spray water on the air conditioners or immerse the air conditioners in water.
Read Before Installation Items to Be Checked (1 ). Verify the type of refrigerant used by the unit to be serviced. Refrigerant Type: R32 (2). Check the symptom exhibited by the unit to be serviced. Look in this service handbook for symptoms relating to the refrigerant cycle. (3). Be sure to carefully read the safety precautions at the beginning of this document. (4 ). If there is a gas leak or if the remaining refrigerant is exposed to an open flame, a noxious gas hydrofluoric acid may form.
Read Before Installation Piping Materials Types of Copper Pipes (Reference) Maximum Operation Pressure Applicable Refrigerants 3.4MPa R22,R407C 4. 3 MPa R32 • Use pipes that meet the local standards. Piping Materials/Radial Thickness Use pipes made of phosphorus deoxidized copper. Since the operation pressure of the units that use R32 is hig_her than that of the units for use with R22, use pipes with at least the radial thickness specified in the chart below. (Pipes with a radial thickness of 0.
Read Before Installation Air Tightness Test No changes from the conventional method. Note that a refrigerant leakage detector for R22 or R4 10A cannot detect R32 leakage. Halide torch ~ R22 or R407C leakage detector Items to be strictly observed : 1.Pressurize the equipment with nitrogen up to the design pressure and then judge the equipment's air tightness, taking temperature variations into account. 2.When investigating leakage locations using a refrigerant, be sure to use R32 3.
