Warning
• Do not use soldering on pipes or other parts containing refrigerant with low-temperature melting
alloys, such as lead-tin alloy with bismuth.
• When using flammable refrigerants, all air conditioners must be filled with refrigerants from the
manufacturer or filled on-site as recommended by the manufacturer.
• Brazing, welding, or mechanical connections must be made before the valve is opened to allow
refrigerant to flow into the system. There should be a vacuum valve to suck air out of the
connecting pipes and/or parts that haven't been filled with refrigerant yet.
• Refrigerant pipes must be protected or covered to prevent damage.
• Maximum working pressure: 4.3 MPa.
• When connecting the fan coil and the condenser coil, consider the maximum pressure.
• The refrigerant for the fan coil and the condenser coil is R32. Use the refrigerant of the same type.
• Split-type air conditioners comply with A-Weighted sound level of more than 70 decibels as per
international standards.
• For pipe installation, use the pipe as short as possible.
• Refrigerant specifications comply with the laws and regulations of each country.
• Management, installation, cleaning, service, and storage should follow the standards set in the
following articles.
• Warning: There must be no obstructions that would impede air flow in the air intake and exhaust
vents.
• Caution: For service, please follow the instructions in this operation manual.
