6 Avoid Freeze Burns! Wear protective gloves when working
with a Cold Trap.
Expose and, if required, clean the COLD TRAP PROBE.
NOTE (HOW SOON TO MOVE THE COLD TRAP PROBE) : There
are two opposing needs to consider. 1) The flex line to the probe, and its
junction, need time to warm somewhat so they are not damaged by the
flexing. 2) However, the probe needs to be removed promptly so the
frozen material on the probe does not drip or fall into the Cold Trap and
eventually cause damage. Allow 10 minutes for the flex line (and its
junction to the probe) to warm before moving; do not wait so long that the
frozen material on the probe begins to melt. Then
use special care to
minimize stress on the line and junction when moving the probe to the
fixture.
Use a cloth wrapped around the probe to twist and remove the deposits.
Remove the cloths and vacuum the base of the probe to remove all
deposits. If necessary, use Scotch Brite
TM
abrasive pad to remove the rest
of the deposits.
7 Apply RELEASE AGENT to the COLD TRAP PROBE.
8 Reinsert the COLD TRAP PROBE into the COLD TRAP HOUSING.
9 Secure parts in fixture for coating.
