**Steps**
**Vacuum**
After turning on the vacuum pump, if the vacuum cannot be achieved, check whether the bottle mouth is properly sealed, whether the vacuum pump itself is leaking, and if the shaft sealing ring is intact. It is also recommended to connect an external vacuum switch to improve the recovery rate and evaporation speed.
**Feeding**
Using the system's vacuum negative pressure, liquid material can be drawn into the rotating flask through a hose at the feeding port. The liquid should not exceed half of the flask’s capacity. Continuous feeding is possible, but care must be taken during the process: 1. Turn off the vacuum pump, 2. Stop heating, and 3. After evaporation stops, slowly open the tube cock to prevent backflow.
**Heating**
The instrument is equipped with a specially designed water bath, which must be filled with water before being powered on. The temperature control range is 0–99°C, but due to thermal inertia, the actual water temperature may be about 2°C higher than the set value. Adjustments can be made as needed. For optimal performance, use water up to one-third to one-half of the bath’s capacity and ensure the power plug is properly removed when not in use.
**Rotation**
Turn on the electrical box switch and adjust the knob to achieve the best evaporation speed. Be careful to avoid fluctuations in the water bath and ensure the cooling water is running.
**Recycling Solvent**
First, open the feed switch to release pressure, then turn off the vacuum pump and remove the solvent from the collection bottle.
**Precautions**
â—† Apply a layer of vacuum grease to the equipment before installation, and ensure all seals and joints are properly installed.
â—† The heating tank must be filled with water before it is energized; never operate it dry.
â—† RE-201D must be securely screwed into the fuse hole (19) to avoid damaging the flask.
â—† If the vacuum cannot be achieved, check: 1. Whether the joints are sealed, 2. Whether the seals are effective.
