SAFETY PRESSURE SWITCH (WITH
MANUAL RESET FUNCTION)
The RG5410A-EXTREME is equipped with an internal Safety Pressure Switch. If the
pressure inside the system exceeds 38,5 bar, the system is switched off automatically.
If the Safety Pressure Switch is activated automatically whilst filling a bottle, it could be
caused by the bottle becoming overfilled.
This is a very dangerous situation! You should take steps immediately to reduce the
overpressure and/or to eliminate the overfilling of the bottle.
