Proper operation of a freeze dryer is essential to achieve optimal results. Here’s a step-by-step guide to help you get started:
Startup Procedure:
- Connect the power cord and check if the main power indicator is blinking. A blinking light indicates that the system is powered on.
- Press and hold the "Total Power" button for three seconds. The "Cold Trap Temperature" display will show the current temperature, and you can release the button once it starts displaying.
- Turn on the "Refrigerator" switch. The chiller will start running, and the temperature will gradually decrease. It's recommended to allow at least 30 minutes of pre-cooling to ensure the cold trap is fully prepared to absorb moisture.
- Press the "Vacuum Meter" button to activate the vacuum system. At this point, the digital display should read “110†and the “103†indicator light will be on.
- Once the pre-cooling is complete, place your items on the drying tray, cover the plexiglass chamber, and tighten both the inflation valve and drain valve (located on the right side panel) clockwise.
- Press the "Vacuum Pump" button to start the pump. The vacuum level will drop below 20Pa, signaling the start of the freeze-drying process. Note: When starting the vacuum pump, press down on the plexiglass cover slightly to ensure a tight seal.
- If using a multi-manifold model, first close the rubber valve by lifting the valve core. Once the vacuum reaches 20Pa or lower, insert the pre-frozen bottle into the lower part of the rubber valve and rotate the plastic valve core 180 degrees. Be aware that the vacuum gauge may rebound slightly, so wait until the vacuum stabilizes at 20Pa before adding the next bottle.
