Compactor
Disassembly
1. Open the valve on the hand pump by turning it counterclockwise as far as
possible until it stops.
2. Turn one or both valves on the front of the Compactor to the “ON”
position. This will release the pressure on the cell assemblies. The
pedestals and cell assemblies should lower in position and the gauges on
front of the Compactor should return to zero.
3. Remove the cell assemblies from the Compactor.
4. Re-position the valves on the front of the Compactor to the “OFF”
position.
5. Remove the receiver from the cell assembly and invert it, replacing and
repositioning it so that the open side of the receiver faces the cell body.
6. Remove the piston and the spacer from the opposite end of the cell body.
7.
Drop the tall 20 mm spacer and position it in place where the thin spacer
had been. Re-position the piston as before.
8. Replace the cell assembly inside the Compactor with the piston on the
upper side.
9. Apply pressure to the cell assembly by turning the valve in front to the
“ON” position and by turning the valve on the hand pump clockwise. Apply
pressure with the hand pump and observe the gauge. The needle will
initially rise, but the gauge will then suddenly drop to a reading of zero.
This happens when the wafer breaks free from the cell assembly and falls
into the receiver. The preparation for this wafer is now complete.
10. Pressure may now be applied to the other cell assembly for removal of
the wafer.
The wafer should go directly to a desiccator in order to prevent moisture
absorption. Moisture will result in swelling and will give erroneous results,
especially when doing comparative analysis studies.
