TANK FOR LEAKS. C2. Antifreeze Solutions —177m,,, 411.Min. II« FII Stardom Antifreeze solutions are necessary if ambient or product delivered temperature drops belowfreezing. �— Chemically acceptable antifreeze solutions include ethylene glycol (automotive antifreeze),propylene glycol(food-grade antifreeze)and Fiberglas Reservoir calcium chloride(non-toxic brine).However,before selecting the antifreeze solution,consult local environmental codes for possible optimal _L restrictions—particularly if using ethylene glycol. 2.slope %Glycol Mixture Hydrostatic Monitor system Freeze Protection (with water) Brine 20OF 20% N/A The liquid to fill the cavity must be gravity fed by pouring liquid into 0°F 30% N/A the standpipe.A water hose maybe used only If it is not screwed or -20OF 40% N/A attached to any of the monitoring fittings.Connecting a pressuriz- -40OF 50% Premixed` ed hose directly to the monitoring fitting will over-pressurize the •as Supplied by ac TANKS CORP, cavity and will damage the tank.
