How to Proceed After the Debugging Is Completed:
Turn on the vacuum box power; the power indicator light should illuminate. For models 6090 and 6210, you must also turn on the temperature control switch. The temperature control instrument will undergo an electric self-check. The PV screen will display the measured temperature inside the working room, while the SV screen will show the temperature set at the factory. The AT and HEAT lights on the temperature control instrument should be lit, indicating that the instrument has entered the heating operational state.
Adjust Settings Temperature
Press the temperature control instrument's function key (SET); after the PV screen displays the SP character, use the key head button to modify the set temperature (the 6090 and 6210 models should be set and modified separately for the 2nd and 3rd gauges; the same applies below).
After the modification, press the SET button. The PV screen will display "ST" to set the timer. If the timer function is not used, keep ST=0. Press SET again to show the workshop temperature on the PV screen and the new set temperature on the SV screen. The AT and HEAT lights will illuminate, indicating the instrument is back in the heating mode. As the workshop temperature approaches the set temperature, the HEAT light will flicker, signifying the heating has entered the PID adjustment phase. It's normal for the instrument to sometimes measure temperatures above or below the set temperature. Once the measured temperature is close to or equal to the set temperature, wait for 1-2 hours for the workshop to reach a stable temperature, and the items to enter the drying phase. For lower required temperatures, use a two-set method, such as setting 60℃ first for a required working temperature of 70℃, then reset to 70℃ after the temperature overshoot starts to drop. This helps reduce or eliminate temperature overshoot and quickly reach a stable temperature.
Vacuum Drying OvenThe studio is not treated for explosion-proof or corrosion-proof, and items that are flammable, explosive, or produce corrosive gases are not allowed for drying. The vacuum pump cannot operate for extended periods, so when the vacuum level reaches the required level for drying the items, the vacuum valve should be closed first, followed by shutting off the power to the vacuum pump. Once the vacuum level is below the required level for drying, the vacuum valve and the vacuum pump power should be turned back on to continue the vacuuming process. This method can extend the lifespan of the vacuum pump.
Damp items should be equipped with a filter between the vacuum drying chamber and the vacuum pump to prevent damp gases from entering the pump and causing malfunctions. After drying, items may become lighter and smaller (in a granular form), so a mesh should be added to the vacuum port in the workspace to prevent the dried material from being吸入 and damaging the pump (or solenoid valve). After multiple uses, the vacuum drying chamber may experience a failure to achieve vacuum, at which point the door seal should be replaced or the door latch extension distance adjusted. When the drying temperature in the vacuum drying chamber exceeds 200°C, a slow leakage may occur. In this case, remove the back panel of the chamber, use a hex wrench to loosen the heater base, replace the seal, or tighten the heater base to resolve the issue.
