The proper user of shrink tunnel can prolong life, reduce the risk of equipment failure, the installation begins to strictly comply with the use of standard use and operating instructions to use from the first day.
Wiring: please ensure that the 380V three-phase four wire power supply electricity, not lack of phase, especially not for lack of neutral wire, such as the lack of neutral wire will result in equipment electrical component burnt, lack of a set of live wire will cause the heating tube side does not light or wind machine, conveying belt are not allowed to occurs.
Shutdown: first to close the heating switch, the switch of fan 10 minutes closed again, running to reduce the temperature of tunnel to avoid the sudden shutdown of tunnel high temperature effects on fan.
Check regularly: screw fastening electrical control box and the wire connecting terminals, especially regular check AC contactor wiring fastening end screw terminals, if loose, long-term in use can cause ignition and burn out electrical components.
