1. Like wrapping machines, heat shrink packaging machines consume a lot of power. Therefore, the power input must be greater than the rated power on the machine's nameplate; otherwise, it may easily burn out the wiring or electrical components.
2. Like packing machines, the machine must be reliably grounded to protect personal safety.
3. Each machine comes with a power cable. The lead wires at the end have power identification symbols. Correct connection is essential; improper operation may result in electric shock.
4. When the machine's specified voltage is three-phase 380V, a neutral wire must also be input. This is a standard three-phase four-wire system, similar to other packaging equipment like vacuum packaging machines. Otherwise, the machine will not function properly and may easily burn out internal electrical components.
5. The machine must be installed horizontally; otherwise, the lifespan of the heating elements will be shortened. For conveyor belt machines, tilted installation will cause the conveyor belt to deviate from the center.
6. After the machine has been used continuously for more than three months, the heat-resistant wiring in the shrink chamber should be inspected and replaced as needed based on its degree of aging. 7. When the machine is working, operators must not allow their hands or other body parts to come into contact with the moving parts, especially since the temperature inside the shrink chamber is extremely high and burns are very easy to occur.
8. After packaging is completed, first turn off the heating switch, then allow the conveyor motor and fan motor to continue running for about 10 minutes before disconnecting the entire power supply.
