PTFE Adjustment
An anti-stick sheet which prevents the bag from sticking to heater bar surfaces is located immediately behind the front plate. The sheet should periodically be inspected for wear or damage. If holes or tears exist, the rolls can be turned (rotated) to cover the contact surfaces with fresh material.
If a change of material is required, turn the main power to the OFF position and unplug the power cord. Lower the inner frame by pulling the handle downward. The rollers are located on the outside lower frame, on the left and right side of the inner frame which extends beneath the side-plates (Fig. 4-17).
To adjust the material, turn the lower roller clockwise approximately 1/4 turn using a flat-head screw-driver. When fresh material is in place, turn the roller counterclockwise releasing ALL of the tension on the sheet.
CAUTION: If sheet tension is not released, the material will tear when the seal bar engages.

PTFE Replacement
Turn the power to the OFF position and unplug the power cord. Remove the four screws which hold the front plate to the inner frame. Pull the front plate from the inner frame and slide the front plate along the guide rods away from the seal assembly.
Then slide the rollers and the roller holder away from the heater bar as a unit. Remove and discard the anti-stick sheet. Replace the sheet and rollers with the new material wrapped on the upper roller. Place the rollers on the roller holder, ensuring springs are seated in the grooves on the rollers. Replace the rollers and holder as an assembly (with the unexpended material on the upper roller). Replace the front plate and retighten the four screws. Adjust the sheet as described in section 4.12.
Note: Fiber spacers are located behind the front gripper plate which may fall when removing the front plate screws.

Pressure Bar (Rubber) Replacement
Located along the inside of the pressure bar is a strip of rubber, held on the pressure bar by a channel, pressing on the edges of the rubber.
The rubber compresses against the front (gripper) plate holding the bag in place during sealing and during bag tear off. If the rubber become brittle, torn, gouged, or otherwise worn, it should be replaced to assure strong seals.
To replace the pressure bar rubber, simply pull one end of the rubber from the channel. The rubber will come out of the channel quickly and easily.
To install a fresh piece of rubber, press one edge of the rubber into the channel then the other edge. Work the rubber into the channel in small increments along the length of the channel (Fig. 4-20).
If you used PTFE anti-stick tape to cover the surface of the rubber, place the PTFE on the rubber along its length. If the PTFE extends beyond Figure 4-20 the rubber, cut off the excess.
Note: PTFE may be added to the pressure bar rubber if the bag sticks to the rubber after loading and sealing. The bag may stick to the rubber if the product and bag is light in weight and if the rubber is dirty.
Note: Frequently clean the rubber with alcohol to remove buildup of dirt or other contaminants.

Anti-Jam Adjustment
The anti-jam device is designed to protect the T-1000 from damage when an obstruction is encountered in the seal area (area between the pressure bar and front (gripper) plate). If properly adjusted, the pressure bar will retract if an obstruction is encountered in the seal area.

Replace Thermocouple Wire
A thermocouple wire brazed to a ring terminal and secured to the top of the upper heater bar, detects the amount of heat the heater bar is emitting. The thermocouple wire is considered a normal wear item and will infrequently fail, requiring replacement.
To determine if the thermocouple is bad, follow these trouble-shooting steps: 1) Locate the
"E13" light (Open Thermocouple Alarm) on the Interface Board (Fig. 4-9). If the light is ON, proceed to step two. 2) Another indicator that the thermocouple wire is bad is the "XO" (Heater
Bar Temp. Readout) LED on the PLC Board (Fig. 4-8) will flash slowly. 3) Additionally, the
“YO" (Heater Circuit) LED (Fig. 4-8) will not be illuminated (unless the Energy Saver has shut off the heater bar after 25 minutes).
If the above conditions are met, the thermocouple is bad and the current to the heater bar has been turned OFF.
To replace the thermocouple wire, turn the main power to the OFF position, unplug the power cord and disconnect the air line.
Remove the front plate and PTFE anti-stick assembly, as described in Chapter 4.13. Remove the screws which holds the ring terminal and the jacketed wire clamp. Disconnect the connector and remove the wire. Reverse these steps to replace the wire.
CAUTION: To avoid stretching or breaking the wire during heater cylinder extension, ensure that the wire is looped free to bend during heater bar movement.
Replace the PTFE assembly and front plate as described in Chapter 4.13.
