A CAUTION This system uses R 410A Refrigerant which operates at higher pressures than R 22 No other refrigerant may be used in this system A CAUTION Scroll compressors require proper rotation to operate properly Failure to check and correct rotation may result in property damage The compressor also uses a polyolester POE oil Mobil 3MA POE This oil is extremely hydroscopic meaning it absorbs water readily POE oil can absorb 15 times as much water as other oils designed for HCFC and CFC refrigerants Take all necessary precautions to avoid exposure of the oil to the atmosphere A CAUTION Do not leave the system open to the atmosphere Unit damage could occur due to moisture being absorbed by the POE oil in the system This type of oil is highly susceptible to moisture absorption POE polyolester compressor lubricants are known to cause long term damage to some synthetic roofing materials A CAUTION Exposure even if immediately cleaned up may cause embrittlement leading to cracking to occur in one year or more When performing any service that may risk exposure of compressor oil to the roof take precautions to protect roofing Procedures which risk oil leakage include but are not limited to compressor replacement repairing refrigerant leaks replacing refrigerant components such as filter drier pressure switch metering device or coil Units
