CAUTION: Although the O-rings may look the same, only O-rings recommended for air conditioning systems must be used. Otherwise, refrigerant leakage may occur at the connection.
Install new O-rings from the air conditioner repair kits whenever connections or fittings are disassembled, unless O-rings are supplied with the new parts.
When replacing an O-ring in a disassemblable joint, carefully determine the fitting design to ensure the correct O-ring type and size is selected.
Before installation, make sure that neither the sealing ring A nor the fitting B are damaged or deformed. Deformed or damaged parts must be replaced. When installing new sealing rings, be sure to lubricate them with air conditioner compressor oil. Failure to follow the recommendations for removing and installing system components may result in refrigerant leakage during air conditioner operation.
