1. Connect the hose to the condensate faucet and connect it to the vacuum pump with a vacuum hose.
2. First inject water into the heating tank. Zui uses pure water, and tap water should be placed for 1-2 days.
3. Adjust the main unit angle: just loosen the main unit and column connecting screws. The host can be tilted between 0-45 degrees.
4. Turn on the condensate, turn on the power 220V/50Hz, connect the evaporation bottle to the host (do not let go), turn on the vacuum pump to let it reach a certain degree of vacuum and let go.
5. Adjust the height of the main machine: press the pressure bar at the bottom of the heating tank, adjust the curvature to the right and left to reach the appropriate position, and then reach the required height by hand.
6. Turn on the speed switch, the green light is on, adjust the speed knob next to the left side, and the evaporation bottle starts to rotate. Turn on the temperature switch, the green light is on, adjust the temperature adjustment knob on the left side, the heating tank starts the automatic temperature control heating, and the instrument enters the trial run. Once the temperature and vacuum are within the required range, the solvent can be evaporated to the receiving bottle.
7. After the evaporation is completed, first turn off the speed switch and the temperature control switch, press the lower pressure rod to raise the main unit, then close the vacuum pump, and open the vent valve above the condenser to make it open to the atmosphere, remove the evaporation bottle, and the evaporation process ends.
The following points should also be noted during operation:
1. The glass parts should be handled gently, washed and dried.
2. The heating tank should be energized after water injection, no dry burning.
3. The grinding equipment used should be evenly coated with a small amount of vacuum grease before installation.
4. The precious solution should be simulated first. Confirm that the instrument is suitable for use after normal use.
5. The precise water temperature is measured directly with a thermometer.
6. End of work, turn off the switch, unplug the power plug.
