Safety Requirements
Mechanical Safety
WARNING: - Excessive Pressure Hazard Volumetric Expansion - The heating of water and
other fluids causes volumetric expansion. The associated forces may cause failure of system
components and the release of high temperature fluids. This can be prevented by installing
properly sized and located compression tanks and pressure relief valves. Failure to follow
these instructions could result in serious personal injury, death and/or property damage.
