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.
