1. Application and Features
- The Electric aspirator 35031-00 produces a low vacuum condition using
Bernoulli's principle by pumping water through aspirator head. When using
35031-00 with rotary vacuum evaporator or for Gel dryer or low vacuum oven,
inflow of a little water or solvent into the equipment do not make trouble to the
instrument. And you can use this equipment continuously if you change the
water in the bath.
- The 35031-00 is manufactured as polypropylene that has chemical resistance
against most solvents. For effective usage, a small quantify of water
(100ml/min) has to be continuously supplied by a user through the drain cock at
the bottom part of the bath and drained through the over-flow nozzle. It reveals
liquid circulation of the inner bath and means dilution that helps the instrument
to be used longer.
- Check-valve is designed for preventing water from flowing backward during the
power failure. But this valve can’t protect the equipment permanently. It is for
short protection that saves the time to fix its original troubles that may be
happened.
To prevent flowing backward of water upon a power failure of the moment, the unit
has a flowing backward double breaker. It only makes users have some times to deal
with the situation however, it does not mean the complete stop valve.

2. Installation
Please read this operating manual carefully before you use this unit.
If the unit is installed on an abnormal installing condition, it might cause damage or
abnormal operating.
1) Please check on the proper voltage for operating. You should check the
electricity in accordance with the ID label plate. (The backside of unit)
Please check on the proper voltage, phase of capacity for an installing place.
Main power must be grounded.
If it would not be, may cause a serious injury or damage on the unit.
2) This instrument is requested not to be used where is inclination and vibration
place.
3) Avoid places with direct sunlight.
4) Prevent overflowing of water in the bath, and do not operate with wet hands.
5) Plug out the power cord when you do not use the instrument.

- Slots for cooling coil
When you need cooling coil, you can put in a cooling coil through these slots.
(Cooling coil is optional accessory.)
4. Handling and operation
Use the machine in dry place, and keep away from flammable gas or dangerous
explosive environment is.
For fear that scale might be occurred in the bath, you had better use Distilled
water.
- Only use inner circulation without infusing cooling water
①Fill up the water in the bath up to the over-flow-nozzle.
(About 2 cm below from the nozzle)
Page 9
②Connect a Y separate type tube to each of the suction ports and also
something which vacuum is needed with silicone Hoses (Ø6).
(Refer to the below image)
③After then, turn on the main power switch.
After the power on, the unit is working and is making vacuuming condition.
In case of using for inner circulation for a long time, if the water temperature in the
bath might increase, the vacuuming condition would be limited.
In addition to the vacuuming condition might be influenced by dissolved gas or
impurities that dissolving in the water.

The above graph shows that vacuuming fluctuation is depending on water
temperature in the bath.
In case of using for inner circulation for a long time, if the water temperature in
the bath might increase by the motor, the vacuuming condition would be limited.
When you use it for a long time, you had better infuse some cooling water to
decrease the water temperature.
- Use with inserting cooling water

5. Precautions for using the organic solvents
①Whenever possible, supply running water regularly in the tank.
☞ Connect the hose for supplying the running water from In/Out cock and
drain from Overflow nozzle.
②If you are using organic solvents, you must supply running water.
After operation, drain the water in the tank. Draining the water will prevent the
unit loss from the organic solvents and vapor.
③If running water cannot be supplied, change the tank water as often as is
necessary for its frequency of use. In case of using the toxic solvents, you
must change the tank water more frequently.
④After operation, Rinse the aspirator thoroughly after each use .
Clean and empty the tank in order to avoid any contamination.
Followings are example of organic solvents which need this sort of special care.

6. Maintenance and its cleaning
1) Cleaning the body
The main plug must be separated from a terminal before cleaning and repairing it.
It might cause an electric shock.
-Remove the power plug from the consent first.
-Clean up the body using a soft cloth or sponge damped with neutral
detergent.
-Wipe with dry cloth.
※Do not use organic solvent.
2) Cleaning the bath
-Clean with sponge or soft cloth with neutral detergent.
-Clean with wet cloth.
※ If you can, please use distilled water to prevent the bath from scaling.
※ If you do not use 35031-00 for a long time, drain the water from the bath.
3) Silicon hose or Connector
- Immerse the silicon hose or connector in the water for 3~5minutes.
- Clean all surfaces with the wet sponge or cloth by neutral detergent.
- Rinse with a wet cloth by clean water.
- Wipe down all surfaces with dry cloth.

1. When the unit stops
running
Check on the fuse
connection.
Exchange with new same one.
Check on the power failure.
Check on the main power
switch is on
Turn on the main power switch.
Check on the terminals of
the motor and capacitor.
If the motor is corroded, request the
service.
If the capacitor terminal has problems,
request the service.
2. Has trouble with the
vacuuming
condition.
Check on the hose nipple
sticks to the check valve.
If it is loose, exchange those.
Check on the temperature
of water in the bath. (over
40℃)
If it has a high temperature, exchange the
water in the bath or connect with a piped
water line to cool it.
3. Making excessive
noise
Check on shortage of the
water.
If it is short of water, fill up the water in the
bath up to the over-flow-nozzle. (Under
about 2 cm of the nozzle)
4. A liquid (water)
leaks out from the
cock part.
Check on the vacuuming
hose gets left out.
