OIL
• Use new synthetic oils such as ester because HFC series refrigerant has less solubility with mineral oils
conventionally used for R22.
• As these new synthetic oils are easily influenced by moisture and dusts, they must be treated more care-
fully than the conventional lubricating oils.
CAUTION
For installation/servicing, take more precautions than the case of conventional refrigerants to avoid moisture
and dusts entering the refrigerant circuit. Also, for storing parts, more precautions must be taken.
2, 3-WAY VALVE
• Review material O-ring, valve core seal for securing suitability with oil.
CAUTION
Check if the valve is suitable for the refrigerant (model) when replacing.
CAUTION
Check if the compressor is suitable for the refrigerant (model) when replacing. Complete welding within 15
minutes after opening the cap when replacing.
COMPRESSOR
• Use better grade of material for sliding parts for securing good lubrication of sliding part as HFC
refrigerant does not contain chloride.
• Review insulating materials
• Increase pressure resistance strength
CAUTION
During storage, due care must be taken so that foreign matters such as dust and water do not enter.
HEAT EXCHANGER
• Review the water,contaminants controlling level
• Use thinner tube to increase pressure Increase capacity for resistance strength (only outdoor unit)
improving performance
CAUTION
Check if the valve is suitable for the refrigerant (model) when replacing.
4-WAY VALVE
• Review materials
