HEATING ELEMENT REPLACEMENT

The heating element expands and contracts during

each sealing cycle and will eventually break over

time. Replace using only Uline heating elements.

Make sure that the machine is turned off
and the power cord is secured before
working on the machine.

Any attempt to use elements designed

for use on another machine or in another
application may not work properly and
may cause damage and/or create a

dangerous situation. Use of non Uline parts
will void all warranties.

Loosen the two clamp mounting screws and

rotate the roller knobs to rewind the Teflon

onto the roller to expose the heating element.

(See Figure 9)

Remove the heating element retaining nuts at

each end of the element (keep for reuse).

Remove the old heating element and

discard.

Inspect the insulator on the lower jaw for signs

of cracks, pits, burn marks, etc.

If the insulation material is worn replace it

before installing the new heating element.

Remove the old insulator when necessary,

clean the area, apply a smooth coating of RTV

adhesive, install the replacement insulation

and allow it to dry for several hours before

installing the new heating element.

NOTE: The heating element has a top
and a bottom. See Figure 9 for proper
positioning and installation.

NOTE: The seal jaw assembly is spring-
loaded on left end, fixed on right end.

Place the left end of the new heating element

over the threaded post at the left end of the

jaw assembly.

Compress the left end of the jaw (spring-

loaded) and place the right end of the

heating element over the fixed threaded post

on the right end.

Make sure that the heating element is

positioned correctly, is not twisted and lays

flat against the lower jaw.

Reinstall the retainer nuts no more than finger-

tight.

Reinstall the lower Teflon

cover.
