Decommission the System
The decommissioning process is performed when the system is going to be moved or taken out of service.
Disassembly is required when performing either of these tasks.
1. Remove the specimen and fixtures.
2. Move the actuator piston rod down to its fully retracted position.
3. Turn off the HSM.
4. Turn off the HPU or shut off valves if the unit is connected to a hard line distribution system. Allow time
for pressure to bleed off before closing the return shut off valve.
5. Remove the accumulator charging pressure from all accumulators.
6. Close the hydraulic supply valve or control and then isolate the system hydraulically. Depending on
your system’s configuration, there is either a manual valve that must be moved to its Off position or an
electronically controlled supply valve that must be turned off. Electronically controlled valves are either
turned off using local controls or the system software interface controls.
Warning :
Electrical components and parts can contain hazardous chemicals and compounds.
Improper disposal of hazardous chemicals and compounds can cause injury and death to
people, animals, and plants. In addition, it can cause contamination of the soil, air, and
water.
Always refer to local codes that govern the disposal of potentially hazardous materials and
follow these codes for the proper handling and disposal of these materials.
7. Isolate the system from electrical power.
After the system electronics, control software, and the system PC are powered down, turn off the
system’s main electrical supply and disconnect all cables.
Warning :
Residual hydraulic pressure can produce a high-pressure spray.
You could be cut by this spray or hydraulic fluid could be forced into your skin.
Do not continue with this procedure unless the system has been isolated from hydraulic
pressure for at least 20 minutes. Always be cautious when you loosen any hydraulic
connection or remove bolts or screws from any hydraulic component. Always allow fluid
pressure to dissipate slowly until completely vented before continuing to loosen. Always
wear gloves and appropriate eye protection.
8. Remove all accessible hydraulic hoses.
• Each hose and hard line will potentially have trapped oil in it.
