CONNECTION DIAGRAM
Note: A good rule of thumb is to replace the Teflon adhesive each time you change your element.
Install a new Teflon adhesive on the seal arm, making sure that it extends past the red fiber plate on the metal seal arm.
Place a new heating element over the Teflon adhesive. Fix the rear end of the heating element by attaching the screw through the eyelet. Tighten the screw.
Attach the heating element, spring and plastic washer to the terminal hook in the front by the handle knob.
Squeeze the spring and insert the terminal hook to its original position at the sealer’s arm.
Place another piece of Teflon adhesive over the heating element.
CHANGING THE BLADE ON CUTTER BRACKET
Note: Use extreme caution when changing blade.
Slide the cutter bracket to the notched slot in the groove of the sealer’s arm and pull upward to remove the entire cutting bracket (w/ old blade attached).
Using a screwdriver, loosen screw which holds the blade plate. Slide blade out with caution.
Put a new blade and then the blade plate. Be sure the blade plate latch is in the second predrilled hole from the tip of the cutting blade.
Make sure that both the blade and the blade plate are in position under the grooves of the cutting bracket.
Place the complete cutting bracket into the groove on the sealer’s arm by placing the bracket through the notched slot first. The blade side should face towards the element side of the sealer.

REPLACEMENT KIT INSTRUCTIONS
- *Always unplug the unit from the power source before making any repairs.
REMOVING THE USED PARTS (ELEMENT/TEFLON)
IMPORTANT POINTS TO REMEMBER
Read all instructions before use. Save these instructions for later use.
Follow all warnings and instructions marked on the product.
There are two Teflon adhesives (one is under and one is above the heating element.)
Unplug this product from the power source before cleaning and/or changing any parts
Peel off the Teflon adhesive strip that covers the heating element.
Do not rest anything on the power cord. Do not place the machine where the power cord may be stepped on or pulled.
Always keep out of reach of children and pets.
This sealer should only be in use with an operator in attendance.
Never insert clothing, hands, fingers between the sealing jaws of sealers.
Squeeze the spring on the heating element hook at the sealer’s arm and release the heating element. Keep the spring hook and plastic washer.
Never touch the heating elements with bare hands while the sealer is plugged into a power source, or in operation, or just finished operation. It will be HOT.
Be sure to check for worn parts before starting operation.
Peel off the Teflon adhesive under the heating element.
Do not operate with a damaged power cord or plug.
Always keep the unit clean. Do not use water. Silicone spray may be used to clean the unit. Be sure the unit is unplugged from the power source before cleaning.
When changing blade (for sealers with cutters), be careful of the sharp edge.
When changing the teflon adhesive, be sure the entire surface under the heating element is covered with a teflon adhesive. Bend down the excess teflon adhesive on both ends. This prevents the heating element from breaking and the machine from grounding.
When replacing the fuse, be sure the exact voltage and ampere is used.
Be sure to keep a record of your model number. Specify this number when ordering parts.
When replacing any parts, be sure to mark down the exact locations of the connections.
Loosen the screw that holds the heating element. A hole is provided for easy access on the base (platform) of the sealer to reach the rear element screw. Simply tilt the unit to loosen the screw.

OPERATING INSTRUCTIONS
Step 1. Set the power switch to ON position.
Step 4. Press the Seal Bar down and seal.
Step 2. Set the Sealing Timer according to film thickness. **Always start with a low setting and increase gradually to the right setting.
Step 5. Tear the resulting bag from the rest of the film. Place the open side between the seal bars and seal the opening.
Step 3. Place the object to be sealed between your film.
Step 6. Use the heat gun to shrink the film evenly.
IMPORTANT POINTS TO REMEMBER
Always unplug unit from power source before attempting any maintenance.
Always keep the sealing platform clean and remove any residue found on the platform and Teflon tape. Silicone spray may be used for this purpose.
When replacing the heating element, always change the bottom Teflon adhesive. The Teflon serves as a barrier between the metal seal arm and the heating element. Never allow the element to come in contact with the sealer arm as this will damage the timer.
Occasionally check the condition of the silicone rubber which will affect the quality of the seal if damaged or worn.

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 damaged or material sticks | Timer set too high or cooling time not long enough | Lower the timer setting and keep pressing the lever for 1–2 seconds after the light goes off. Page 2 |
| Poor seal quality | Worn or dirty Teflon cloth, or worn or dirty silicone rubber | Clean or replace the Teflon cloth and the silicone rubber sealing bar. Page 2 |
Frequently asked questions
What sizes are available?
Sealing lengths are 14" (W-350I), 20" (W-500I), 26" (W-650I), 30" (W-750I) and 36" (W-900I). IC models have the same sizes with a cutter. See page 5.
Should I replace the Teflon when I replace the element?
Yes. Always change the bottom Teflon adhesive when you replace the heating element. It keeps the element from touching the metal arm, which can damage the timer. See page 5.
How do I change the cutter blade?
Slide the cutter bracket to the notched slot and lift it out, loosen the blade plate screw, fit the new blade and plate, and refit the bracket with the blade facing the element side. Use extreme caution. See page 3.
How do I clean the sealer?
Unplug it, then remove residue from the platform and Teflon tape. Do not use water. Silicone spray may be used. See page 5.
