Teflon tape
1.
Turn off CoreLok and unplug the power
cord.
2.
Open the chamber door.
3.
Unplug the two wires from the sides of the
seal bar assembly.
4.
Remove the seal bar from the machine by
lifting straight up on the seal bar.
5.
Pull off the Teflon tape strip and discard.

(fig. 1, pg. 41)
6.
Using a 2mm Allen wrench, loosen the
setscrew for the seal wire on both sides of
the seal bar.
(fig. 2, pg. 41)
Discard the seal
wire and fiberglass insulator strip.
7.
Once the seal bar is completely clean of
any residue, place the new fiberglass
insulator strip on the seal bar. Insert the
free end of the new seal wire through the
slot in the brass contact and tighten the
setscrew.
8.
Insert the other end through the slot and in
the brass contact. Feed the end of the
seal wire through the tightening tool so that
the seal wire winds around it. Place a
slotted tip screwdriver up against the
bottom edge of the brass contact while
you continue to tighten the seal wire with
the tightening tool.
(fig. 3, pg. 41)
Note:
The slotted tip screwdriver is used as a
rest for the tightening tool. If you don’t use
it, then you might break the seal wire off at
the bottom of the brass contact. Secure
the seal wire in place by tightening the
setscrew with the Allen wrench.
9.
Apply the new Teflon tape evenly over the
seal bar.
10.
Reinstall the seal bar and connect the
wires on both sides of the seal bar
assembly.
