9. Manual operation:
During the manual operation the operator is responsible for the correct gas handling.
Individual valves and components can be actuated in manual operation.
The device is equipped with four solenoid valves which are to be opened under certain conditions only
(pos. 133, 132, 137, 601).
The solenoid pos. 133, 132 and pos. 601 cannot be opened under overpressure.
The solenoid valve pos. 137 only opens if the evaporator has reached its operating temperature.
These solenoid valves can only be preselected and open as soon as the corresponding conditions are
fulfilled.
In case the solenoid valve pos. 137 is preselected or opened the evaporator is activated as well.
For detailed information on the manual operation please see chapter 2.
