Page 4: General Installation Requirements
Users Responsibility – This manufacturer anticipates the proper installation and care in use of the product. As with any hot water system, there is a risk of property damage and personal injury inherent in the use. NTI cannot supervise the installation and therefore makes it a specific condition for the warranty that the customer will supervise the installation and use of the product to be sure they are performed in accordance with the instructions and I.O.M. -
Page 5: Safe Temperatures For Potable Water
Trin & Stor Indirect Water Heaters Installation and Operation Instructions Safe Temperatures for Potable Water Two factors used to determine safe hot water temperatures are Legionella and scalding. Potable water needs to be stored at temperatures hot enough to limit the growth of Legionella, yet be cool enough to prevent scalding. Since both hazards present a potential risk to the user, they must be monitored and controlled. - Page 6 │ Trin & Stor Installation and Operation Instructions Indirect Water Heaters Legislation and Guidelines - At the time this document was written, standards and guidelines regulating the prevention of Legionella in the United States and Canada were mostly voluntary. The American Society of Heating, Refrigerating and Air-Conditioning Engineers, Inc. (ASHRAE) is currently in the process of converting its guideline entitled "Minimizing the Risk of Legionellosis Associated with Building Water Systems"...
