1. Place the items that need to be dried
into the vacuum box, close the box door, close the vent valve, turn on
the vacuum pump, connect the vacuum
pump to extract air, and achieve the required vacuum degree in the
box. Close the vacuum valve and turn
off the power supply of the vacuum pump.
2. Turn on the power supply of the vacuum box, select the desired set
temperature, and the temperature
inside the box will begin to rise. When
the temperature inside the box approaches the set temperature, the
heating indicator will flash on and
off, and the vacuum box will be in working condition. Turn off the power
switch according to the different
drying times required for different items.
3. After drying, the power should be turned off first, the air release
valve should be turned on, and the
vacuum inside the box should be
relieved. Open the box door and take out the items (when opening the
box,
due to the deformation of the sealing
ring and glass door suction, after releasing the vacuum, wait for a
moment for the sealing ring to return
to its original shape before opening the box door).
