Prolong the life of your new air conditioner by adding this Refrigerant Safety Indicator. The indicator shows you the health of the liquid refrigerant, which should be dry all the time. If there is any moisture in the refrigerant, it will turn into a harsh acid and dissolve the insulating varnish from the compressor motor windings, shorting-out the compressor and ruining your system. The indicator will protect you from this by changing colors to indicate the system has a problem. Your AC technician can then correct the problem before it damages your equipment. The indicator easily fits inline with the 3/8" liquid line connected to your condenser.
