Turn on the power. When the blue button lights up, the unit is ready for use. Pressing the yellow VAC START button will turn on the pump that is connected to the vacuum pump interlocking outlet on the back of the unit, and then vacuuming starts.
Secure cold trap for the sublimated waterBecause of the direct cooling system in which water vapor is directly coagulated and collected on the surface of the cooling coil in the trap chamber, the cooling temperature becomes almost the same as the trap temperature.
Trapped water is quickly defrosted by hot gas. When the DEFROST button is pressed, hot gas will flow into the coil of the cold trap, and ice equivalent to the dehumidification capacity can be defrosted in about 30 minutes.
