System water including additives must be

practically non-toxic, having a toxicity

rating or Class of 1, as listed in Clinical

Toxicology of Commercial Products.

Use of Antifreeze in the Primary System

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.

Filling the Inner (Domestic) Tank and

System

cold supply piping to the ELITE and on the

domestic hot outlet piping to the building.

3. Vent any air from the domestic piping sys-

Continue filling the domestic system until

there is a constant flow of water from the

faucets.
