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
Proceed with filling instructions for the
inner and outer tanks only after ensur-
ing the water meets the requirements
listed in this installation manual. Failure
to comply could result in damage and
improper operation of the unit.
Never operate the ELITE unless both the
inner and outer tanks are completely
filled.
Always fill the inner tank prior to filling
and pressurizing the outer tank. Failure
to properly fill the inner tank could
result in damage to the inner tank.
1. Ensure the domestic drain valve is closed.
2. Open the isolation valves on the domestic
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-
tem by opening faucets near the unit.
Continue filling the domestic system until
there is a constant flow of water from the
faucets.
4. Close the hot water faucets.
Filling the Outer (Primary) Tank and
System
1. Close the primary drain valve located
on the rear of the unit and any manual
