Use of Antifreeze in the Primary System
WARNING
NEVER use automotive or ethylene gly- col antifreeze or undiluted antifreeze in the primary system as freeze protection. This can cause severe personal injury, death or substantial property damage if ignored.
Determine the antifreeze fluid quantity using the system water content volume and following the antifreeze manufacturer instructions.
The primary outer tank volume of the ELITE is 20 gallons. Remember to include the volume of the expansion tank.
Check with local codes requirements for the installation of back flow preventers or actual disconnect from the make up water supply line.
Ensure the concentration of antifreeze to water does not exceed a 50/50 ratio.
