The componentsshown are not to scale. The refrigerant and refrigerant oil are clear in color and not visible in this drawing. The smallarrows inside the components and connecting hoses show the direction of refrigerant flow. The location of eachcomponent is in parenthesis.Allow only certified personnel to service and maintain the air conditioning system. The Clean Air Act of 1992 states thatanyone who works on air conditioning systems must be certified as proof of their training. Organizations such as theMobile Air Conditioning Society (MACS) and the National Institute for Automotive Service Excellence (ASE) areapproved by the Environmental Protection Agency (EPA) as organizations with approved independent testing andcertification programs. Contact your local EPA office for more information.REFRIGERANTREFRIGERANTREFRIGERANTREFRIGERANTREFRIGERANTAlways use refrigerant R134a in this equipment.WARNINGWARNINGWARNINGWARNINGWARNINGAir conditioning systems operate under extreme high pressure.
