OPERATING INSTRUCTIONS
TIPS FOR SUCCESSFUL SEALING
Before operating, check the heating element, teflon cover, teflon adhesive and sealing pad (silicone rubber).
If the seal is broken or damaged, decrease the Sealing Time
If the seal is not fully sealed, increase the Sealing Time
If the sealing material sticks to the sealing pad, decrease the Congealing Time
If the width of the seal is not perfect or does not match the size of the element, increase the Congealing Time.
Always keep the sealer clean and remove any residue found on the platform and teflon cover. Silicon spray may be used.
Set the Power Switch to ON position.
Set the Selector Switch to MAN position for MANUAL OPERATION, or AUTO position for AUTOMATIC OPERATION.
AUTOMATIC OPERATION
Adjust the Sealing Time (Heating Time) according to the thickness of the material. (Always start with a low setting and increase gradually).
Adjust the Congealing Time (Pressing Time or Cooling Time) according to the thickness of the material. Congealing Time allows the seal a chance to set and cool.
When replacing the heating element, always check the condition of the bottom teflon adhesive. A worn teflon adhesive will cause damage to the element.
Adjust the Recycle Time according to the speed and frequency of the sealing cycle. Recycle Time is based on the working speed of the operator.
Occasionally check the condition of the silicon rubber for wear or burn as a damaged silicon rubber will affect the quality of the seal.
Be sure to unplug the power cord before replacing any parts.
Insert the material to be sealed and allow the sealer to operate in AUTO mode.
MANUAL OPERATION
Adjust the Sealing Time (Heating Time) according to the thickness of the material.
Adjust the Congealing Time (Pressing Time or Cooling Time) according to the thickness of the material.
Insert the material to be sealed and activate the upper jaw of the sealer by pressing down on the Foot Switch. (Recycle Time must be turned off.)

Quick start
- Check the heating element, Teflon cover, Teflon adhesive and silicone sealing pad.
- Set the Power Switch to ON.
- Set the Selector Switch to MAN for manual or AUTO for automatic operation.
- Set the Sealing Time for the material thickness, starting low and increasing gradually.
- Set the Congealing Time so the seal can set and cool.
- Auto mode: set the Recycle Time to your working speed and insert the material.
- Manual mode: turn off Recycle Time, insert the material and press the Foot Switch.
Troubleshooting
| Problem | Likely cause | Fix (from the manual) |
|---|---|---|
| No sealing, power lamp is off | Disconnected plug, broken power cord, or broken transformer | Check or change the plug, repair or replace the cord, or replace the transformer. Page 2 |
| No sealing, power and sealing lamps are on | Broken heating element, loose spring hook, or poor terminal contact | Replace the heater, tighten the spring hook connection, or clean and adjust the terminals. Page 2 |
| No sealing, power lamp on but sealing lamp off | Microswitch issue or defective microswitch | Adjust the microswitch lever or position, or replace the microswitch. Page 2 |
| Seal is broken or damaged | Sealing Time is too high | Decrease the Sealing Time. Page 3 |
| Seal is not fully sealed | Sealing Time is too low | Increase the Sealing Time. Page 3 |
| Material sticks to the sealing pad | Congealing Time setting | Decrease the Congealing Time. Page 3 |
| Seal width does not match the element | Congealing Time is too short | Increase the Congealing Time. Page 3 |
Frequently asked questions
What is the difference between AUTO and MAN mode?
In AUTO the sealer cycles by itself using the Recycle Time. In MAN you press the Foot Switch to close the upper jaw, with Recycle Time turned off. See page 3.
What does Congealing Time do?
Congealing Time (pressing or cooling time) gives the seal a chance to set and cool before the jaw opens. See page 3.
How do I keep the sealer working well?
Keep the platform and Teflon cover free of residue (silicone spray may be used), and check the silicone rubber for wear or burns. Unplug before replacing parts. See page 3.
