Connect Water Piping CONTINUED

Use with refrigeration systems:

•Install boiler so that chilled medium is piped in parallel with heating boiler. Use appropriate valves to prevent chilled medium from entering boiler. Consult I=B=R Installation and Piping Guides.

•If boiler is connected to heating coils located in air handling units where they can be exposed to refrigerated air, use flow control valves or other automatic means to prevent gravity circulation during cooling cycle.

Hot Water Can Scald!

•Consumer Product Safety Commission and some states recommend domestic hot water temperature of 130°F or less.

•When installing an automatic mixing valve, selection and installation must comply with valve manufacturer’s recommendations and instructions.

•Water heated to a temperature suitable for clothes washing, dish washing and other sanitizing needs will scald and cause injury.

•Children, elderly, infirm or physically handicapped persons are more likely to be injured by hot water. Never leave them unattended in or near a bathtub, shower or sink. Never allow small children to use a hot water faucet or draw their own bath. If anyone using hot water in the building fits this description, or if state laws or local codes require certain water temperatures at hot water faucets, take special precautions:

—Install automatic mixing valve set according to those standards.

—Use lowest practical temperature setting.

—Check water temperature immediately after first heating cycle and after any adjustment.
