Check System and Domestic Water Chemistry

WARNING

Do not use petroleum-base cleaning or sealing compounds in the primary sys- tem. Damage to seals and gaskets in the system components could occur, result- ing in substantial property damage.

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.

Water pH Level 6.0 to 8.0

Maintain the primary system water pH between 6.0 and 8.0. Check using litmus paper or contact a water treatment compa- ny for a chemical analysis.

If the pH does not meet this requirement, do not operate the PERFORMANCE PLUS or leave the unit filled until the con- dition is corrected.

Water Hardness Less Than 7 Grains

For areas with unusually hard water (hard- ness above 7 grains) consult a water treat- ment company.

Chloride Concentration Less Than 80 mg/L

For those installations that use a water soft- ener or conditioner, consult the water treat- ment company.

NOTICE

Any water conditioning system must be installed and maintained in accor- dance with the water conditioner’s manufacturer’s specifications and within the operating guidelines of the

PERFORMANCE PLUS.

Chlorinated Water

Do not use the PERFORMANCE PLUS inner or outer tank to heat a swimming pool or spa directly.

Maintain the chlorine level of the water in the inner and outer tanks at levels consid- ered safe for drinking.

Flush Primary and Domestic System to Remove Sediment

The installer must flush both the primary and domestic system to remove any sedi- ment to allow proper operation of the PER-

FORMANCE PLUS.

Flush the systems until the water runs clean and is free of sediment.

For primary zoned systems, each zone should be flushed through a purge valve. Purge valves and isolation valves should be installed on each zone to allow for proper flushing of the system.

Check and Test Antifreeze

For primary systems containing antifreeze solutions, follow the antifreeze manufac- turer’s instructions in verifying the inhibitor level and to ensure the fluid char- acteristics are within specification require- ments.

Due to the degradation of inhibitors over time, antifreeze fluids must be periodically replaced. Refer to the manufacturer of the antifreeze for additional instructions.
