7 Operation
7.1 Operating method
Set your chiller for the rated lowest temperature. Always run the loop. Allow the chiller to cool the entire loop
until it is close to the set temperature. Raise the bath until the water covers half of the outside of the flask.
Turn on the bath heating and set between 50C –75C. Turn on the rotation for as fast as possible, while
stable. If the glass wiggles, slow the rotation down. Place the cover over the boiling flask onto the edges of
the bath. The vacuum should be started. Add a tube that runs from the feed port down to your vessel. Start
the run when the chiller reaches 29C, when set for 30C. Open the feed port to begin filling the boiling flask.
Do not fill the flask more than half-way. The evaporation will begin at this point. Evaporation can be boosted
with pre heated solution. 40-45C. It will be necessary to refill the boiling flask over time. When the receiving
flask is full. Turn off the vacuum and vent the vacuum in the system. Empty the receiving flask. Then close
any valves used to vent the vacuum. Turn the vacuum on again and continue to evaporate.
7.2 Storage
For long periods, please shut off the power switch and disconnect the power. Empty the water bath, boiling
flask, receiving flask and condenser coil(s) Allowing time to dry completely. Cover while in storage.
8 Maintenance
1. Please shut off the power switch and disconnect the power cord before any maintenance.
2. Please use damp soft cloth to wipe clean. Stubborn stains should be cleaned by neutral detergents.
3. The maintenance of internal electrical and heating parts must be performed by professionals or trained
electricians.
4. Do not directly splash water over the product or use abrasive powder, diluent, oil, kerosene, acidic
