SAFETY PRESSURE SWITCH (WITH
.
MANUAL RESET FUNCTION)
The MINIMAX-E 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 while filling a bottle, it may 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.

The following precautions should be taken if the Safety Pressure Switch is activated:
a) Suspected overfilling of the recovery bottle
Connect the recovery bottle to another bottle with spare capacity so that the pressure is
reduced to a safe level. This action should also reduce the pressure in the output line
from the MINIMAX-E. Proceed as normal after resetting the Safety Pressure Switch
(see below).

1) Check that the recovery bottle is not overfilled.
2) Close the system valves, recovery bottle valves and MINIMAX-E valves.
