VOLTAGE – CONTROL IMPORTANT NOTES

  1. When shrink wrapping is carried out, but the film is not uniform or not complete, please modify by increasing the shrinking temperature or decreasing the speed of the conveyor.
  2. If the film tears or blows during shrink wrapping, please modify by decreasing the shrinking temperature or increasing the speed of the conveyor.

When machine operation is complete, please turn off the following switches in order

  1. Turn the “Temperature Adjustment” back to 0.
  2. Turn off the “Temperature Switch” and keep operating the conveyor for at least 10 minutes to allow the shrink tunnel to cool
  3. Turn the “Conveyor Adjustment” back to 0.
  4. Switch off the “Conveyor Start.”
  5. Turn off the “Source Switch.”

Quick start

  1. Set the shrinking temperature and conveyor speed for your film.
  2. If the film shrinks unevenly or incompletely, raise the temperature or slow the conveyor.
  3. If the film tears or blows, lower the temperature or speed up the conveyor.
  4. When finished, turn the Temperature Adjustment back to 0.
  5. Turn off the Temperature Switch and keep the conveyor running for at least 10 minutes so the tunnel cools.
  6. Turn the Conveyor Adjustment back to 0, switch off Conveyor Start, then turn off the Source Switch.

Frequently asked questions

What power does the CN-4520 shrink tunnel need?

The CN-4520 runs on 220V/240V and is rated at 6kw. The CN-4015 is 5kw and the CN-4520AL is 8kw. See page 3.

How do I shut the shrink tunnel down safely?

Turn the temperature to 0, switch off the heat and let the conveyor run at least 10 minutes to cool the tunnel, then set the conveyor to 0, stop it and turn off the source switch. See page 4.

Why is my shrink film tearing?

The manual says to lower the shrinking temperature or increase the conveyor speed. See page 4.
