Start-Up Preparations

NOTICE

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

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 PER- FORMANCE PLUS 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.

NOTICE

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.

Filling the Inner (Domestic) Tank and System

WARNING

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.

CAUTION

Never operate the PERFORMANCE PLUS unless both the inner and outer tanks are completely filled.

CAUTION

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 PERFOR- MANCE PLUS 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 or automatic air vent in the system.

2.Open all system isolation valves.
