11.2.2 Maintenance sealing bars
Servicing the sealing bars includes replacing the Teflon tape or the sealing wire. The Teflon tape on the
sealing bars must be replaced if there are signs of scorching. It may be necessary to replace the sealing
wires at the same time. Please read section 11.2.2.1 "Replace Teflon tape and sealing wires".
New sealing bars, or bars with newly installed sealing wires, have to be calibrated and burnt-in after in-
stallation and prior to production. Please read section 11.2.2.2 "Calibration and burn-in sealing bars".
NOTICE
Keep a spare set of sealing bars so that these can be exchanged when necessary without major
interruptions to the production cycle and return to Inauen Maschinen AG for renewal.
