6. When replacing the heating elements, always replace the PTFE adhesive under
the heating element. A worn PTFE adhesive can cause the heating element to break
prematurely. The PTFE adhesive works as a barrier between the body of the sealer and the
element. Never allow the element to come in direct contact with the sealer body as that will damage
the timer.
7. Occasionally check the condition of the silicone sponge/compression foam for wear or burns. A
damaged silicone rubber will affect the quality of the seal.
8. Be sure to turn off the power or unplug the unit before replacing any parts.
