! CAUTION R-410A systems operate at higher pressures than R-22 systems. Do not use R-22 service equipment or components on R-410A equipment. ! CAUTION Only use evaporators approved for use on R-410A systems. Use of existing R-22 evaporators can introduce mineral oil to the R-410A refrigerant forming two different liquids and decreasing oil return to the compressor. This can result in compressor failure. ! CAUTION When coil is installed over a finished ceiling and/or living area, it is recommended that a secondary sheet metal condensate pan be constructed and installed under entire unit. Failure to do so can result in property damage. ! CAUTION THE COMPRESSOR HAS AN INTERNAL OVERLOAD PROTECTOR. UNDER SOME CONDITIONS, IT CAN TAKE UP TO 2 HOURS FOR THIS OVERLOAD TO RESET. MAKE SURE OVERLOAD HAS HAD TIME TO RESET BEFORE CONDEMNING THE COMPRESSOR. !
