CAUTION: Single wall heat exchangers must use a heat transfer medium such as water or other non-
toxic fluids having a toxicity rating of Class 1, as listed in Clinical Toxicology of Commercial Products
(current edition)
.
The pressure of the heat transfer medium must be limited to a maximum of 150psi by an
approved pressure relief valve.

1.5 WATER QUALITY
Always use good quality water to prolong the life of the tank. Water that is safe to drink and even city
water is not necessarily good quality water for the tank. The use of filters can prevent corrosion and
reduce sediments inside the tank. Water hardness, pH, and chlorides must be controlled to normal levels.
•
PH levels must be between 6.0 and 8.0 and dissolved chlorides below 100ppm.
If you are unsure, use a water softening system or consult a qualified water treatment expert.
NOTE: All improper use as detailed above could void the warranty of the tank.
