Chemically acceptable antifreeze solutions include ethylene glycol (automotive antifreeze),propylene glycol(food-grade antifreeze)and F �HeSC,K.v, calcium chloride(non-toxic brine).However,before selecting the antifreeze solution,consult local environmental codes for possible restrictions—particularly if using ethylene glycol. 2-Sm %Gfyeol Mixture Z Hye.oawbc Monitor system Freeze Protection (with water) Brine 20°F 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 may be used only if it is not screwed or –20°F 40% N/A attached to any of the monitoring fittings.Connectingapressuriz- -40°F 50% Premixed' ed hose directly to the monitoring fitting will over-pressurize the cavity and will damage the tank. •AssuXlwiby O/CTa Cwp. If the tank is sloped fill the annular space from the low end of the sloped If using glycol antifreezes,mix the antifreeze solution before pouring into tank.Continue to fill the cavity with water until liquid begins to overflow the the tank cavity.Brine antifreeze provided by O/C tanks is premixed and standpipes.Refilling the cavity through the fill standpipe will be required. ready to use without the need for mixing or blending. After water overflows the Fiberglas reservoir,replace the plug in the reservoir fitting. C3.

Remove a primary tank fitting plug and inspect the inner tank for leaks.Do not enter the tank without adequate safety protection. C4.
