Safety information

The HP Modular Cooling System G2 is tested to the maximum pressure (PS) of 8 bar (116 PSI) without fluid trapped inside by closed, external valves.

If valves are installed on the external pipe work that could potentially trap fluid inside the MCS unit, special precautions must be taken. In order to prevent severe plumbing failure due to extreme pressure, use an expansion tank with a preinstalled safety valve in the plumbing circuit connected to the unit.
