Emergency operation
Operation
– continued –
During emergency unloading the following actions will take place:
n
Opening of bottom valve
n Closing of bottom valve
If both bottom valves are to be opened, open first the bottom valve for the gas phase and then the one for
the liquid phase.
See drawing on page 4
. Unscrew the sealing plug
J of the bottom valve located in the bottom of the actuating cylinder B.
A small amount of oil might escape. Put the sealing plug J in the operating device E.
2. Unscrew one or two of the required screws for sealing off the opening for emergency unloading K from
one of the two operating devices E and apply a smear of commercially available lubricant to them.
They are screwed one below the other at the back of the operating device E.
4. Screw the sealing-off screw K into the thread at the bottom of the actuating cylinder B in order to open
the bottom valve.
5. Open the lateral shut-off valves A to start the loading / unloading process.
Use the emergency operation of the bottom valves only if both hydraulic hand pumps have
failed or, for any other reason, there is not enough pressure for opening one or both bottom valves.
In case of emergency operation a rapid-action closing of the bottom valve is not possible.
Warning
If both bottom valves are to be closed via emergency operation, first close the bottom valve for the liquid
phase and then the one for the gas phase.
See drawing on page 4
. To close the bottom valve unscrew the sealing-off screw for emergency unloading
K out of the bottom
of the actuating cylinder B. The spring in the bottom valve effects the closing.
2. Once the emergency loading/unloading process has been accomplished, screw the sealing-off screws K
back into the rear wall of the operating device E.
3. To finish the loading/unloading process, close the shut-off valves A and attach the sealing plugs to
the shut-off valves.
4. Defective bottom valves must be permanently marked in order to avoid inadvertent re-commissioning.
Do not screw sealing plugs J into defective bottom valves.
5. The cause of the malfunction must be ascertained and eliminated by qualified personnel!
In case of emergency operation a rapid-action closing of the bottom valve is not possible.
When the emergency operation of one or both bottom valves is finished, find and eliminate the
cause for the malfunction. Note that the repeated or continuous application of the emergency
operation is considered as improper usage. The resulting risk will have to be borne by the user alone.
The manufacturer hereby expressly rejects any claims for any resulting damage.
