4 1. Application and unique features 1) Application (1) You can obtain a perfect dry compound free of residues from a solvent or moisture on a powder state or a resin state of a compound. (2) You can completely separate a solvent from a solution without drying a phase of the substance that contains humidity or other solvents. (3) Vacuum drying is a good method in an aspect of and affects a process and an effect when you dry or evaporate the high boiling point of a solvent. (4) The equipment is effective of drying a sample that could be exploded when it reads oxygen in a drying condition of high temperature. (5) The equipment can prevent oxygen from air when you dry a solid media in anaerobic condition. A sample that the tissue of an organism is dense can be dried in vacuum condition. (6) The equipment is useful in experiment a vacuum-packed food in a long term. 2) Unique features (1) Vacuum oven can be used for biotechnology, chemistry, pharmacy, biology, and etc. Furthermore, this machine realizes CLS (Custom Logical Safe) Control System which Convenience and Safety is considered on the top priority. (2) CLS-Control System, which means a controller that has product specific safety features, is the safest controlling device to be developed by Jeio Tech researchers. It is used to make products with heaters safer in environments that require perfect safety against heat, ie:- where flammable chemicals are used. (Patent No ) (3) It is very easy to set Temp. and Timer with Display panel. (4) Silicone material for High temperature purpose is adapted for Door gasket. (5) The unit can be easily vacuumed by using vacuum pump. (6) It is very convenient to open and close door. (7) Valve for Vacuum line and Vent line(release line) is designed separately. Vent line is designed to adapt narrow tube for slow air incoming to chamber so that Vent system can Page 4

5 prevent diffusion of powder type of sample. Incoming air to Chamber can be controlled with the adjustable Vent valve. (8) Safe-circuit is adapted for over-current and over temperature of heating element. (9) Temperature sensor is attached to shelf that sample is put on. So, the temperature sensor detects temperature of sample container. The reason is that we adapt this design is conductivity is main method of heating transfer in vacuum state. 2. Installation and cautions (1) Scope of delivery. Main body (1set), Operation manual (1EA), Communication CD (1EA), Communication cable (1EA) (2) The unit is quite heavy. Please move the unit with proper moving tool or 2 people together. (3) This unit works correctly with proper power supply. Please check that power supply (voltage and frequency) harmonizes with ID Plate information at the rear of the unit. Over earth wired second grade power supply must be used and connect power plug of the unit to a socket bearing ground terminal. Please use earth-wired power supply If main power does not connect to earth, the unit and human can be injured seriously. (4) Wall socket or a socket should be located near the unit. (5) Please install the unit in the flat place where prevent vibration and shock. (6) Please let the unit avoid heat source and direct sun light and let the unit located in ambient temperature range in 5 C ~ 40 C and relative humidity lower than 80%. (7) Please keep the Control Box of the unit away from Humidity, organic solvent, a dust and corrosion gas. (8) Please let the unit avoid organic solvent like Acetone and Methyl Chloride and also avoid from instrument the strong high frequency noise. (9) Door can be opened up to 180 to left side and so please consider enough space. Page 5

6 (10) Please do not put the unit around machine caused strong high frequency noise such as High frequency welder, High frequency sewing machine, High capacity SCR controller) 3. Cautions during operation 1) Caution (1) You'd better use the air that is not containing moisture when you inject air in the oven. Because the sample that has dried in the vacuum oven needs to be maintained in dried condition. To satisfy above mentioned condition, Cold trap and Chemical moisture trap can be used. (2) The vacuum pump that is used in producing a vacuum condition needs a lubricant which has extremely low vapor pressure (10-4mmHg), however, unfortunately, if the lubricant is contaminated by a solvent which has relatively higher vapor pressure than low vapor pressure lubricant, the efficiency of a vacuum pump is going to be fell down. So, physical sanction that prevents the pump from damaging is needed in prior process. The vacuum pump needs cleaning for long-term use. To satisfy above-mentioned condition, Cold trap and Particle filter can be used. (3) Before using this unit, you'd better have full grip of the sample's physical and chemical features. In vacuum condition, inner chamber temperature must be lower than the sample's Boiling Point. And do not use a sample that is easy to be sublimated. Because if not, sublimated sample may block up the vacuum line. In vacuum condition, decomposition of organism is easy to be occurred. So, be careful to set up a setup temperature. (4) Before turn the vacuum pump off, you have to make Vacuum valve handle set to Close position and stop vacuum pump. Otherwise, vacuum pump oil may flow backward into the chamber due to vacuum state of chamber. (5) Exchange vacuum oil regularly at an 100hr interval of vacuum pump use. (6) Equip cold trap and filter to protect wall of rotary vane pump cylinder and prevent vacuum oil contamination. Do not put in explosive, combustible samples such as Alcohol, Benzene, and other Page 6

7 inflammable solvent inside the chamber. Be careful of touching the unit during or after operating. It is very hot! (7) Please do not insert any material that can apply electric current or can be inflammable. It can cause electric shock or a fire. (8) When clean the unit, do not pour water to external body directly. (9) A person of Jeio Tech Co.,Ltd. or appointed personnel from Jeio Tech Co.,Ltd. can provide service of applied circuit or electric part in the unit. (Heating machine can cause a fire if the machine is treated by unauthorized personnel) 2) Ideal Vacuum Unit system Page 7

8 3) How to vacuum and vent (release) How to create vacuum; (1) Put in the sample in the oven and close the door. (2) Vent valve handle on right side must be located to close. (3) Turn Vacuum valve handle on the left side to 12 o clock position (OPEN) (4) Connect hose between Vacuum pump and Vacuum nozzle on the above of Vacuum valve. (5) Start Vacuum pump to create vacuum inside chamber. (5) After completing vacuuming, turn Vacuum valve handle on left side to 3 o clock (Close) (6) Stop the Vacuum pump. How to release vacuum (Vent) (1) Turn Vent valve on the right side to OPEN. At the moment coming- out air from chamber can be controlled by handle. Before stop vacuum pump, you must set Vacuum valve handle to Close. Otherwise, vacuum pump oil can be flow into inside chamber due to vacuum state. Page 8
