Caution
DO NOT USE AUTOMOTIVE GRADE ANTI-FREEZE AS A SUBSTITUTION FOR
INDUSTRIAL GRADE GLYCOL. IT DOES NOT CONTAIN THE PROPER
INHIBITORS FOR THIS APPLICATION AND WILL LEAD TO EVENTUAL
DAMAGE OF THE SYSTEM.
Caution
SINCE THE WATER USED TO MIX WITH THE GLYCOL WILL AFFECT THE
CORROSIVITY OF THE MIXTURE, ONLY HIGH QUALITY DEMINERALIZED
WATER THAT HAS BEEN DISTILLED, DEIONIZED OR REVERSE-OSMOSIS
PROCESSED SHOULD BE USED. THIS WATER MUST HAVE A
CONDUCTIVITY OF NO MORE THAN 5 MICROSIEMENS (OR HAVE A
RESISTANCE OF LESS THAN 200K OHMS).
