Safety Information

Safety Precautions

If the motor overloads - stop operation immediately.

If you continue operation under abnormal conditions, the motor will stop automatically. If the
motor stops, turn the control knob to the minimum and turn off the power switch.

Overload condition exists when the motor surface temperatur e reaches more tha n 90

＊＊＊＊

A cause of motor overheating is seized ball bearings.

Make sure that the volume knob indicates “min” before turning the unit on.

Make sure that the control knob is at “min”. If the control knob is not turned to “min”, the
evaporation flask turns round when you turn on the power switch.

Move the lift up or down after you stop rotation of the evaporation flask.

If the lift is moved up or down while the evaporation flask is rotating, scalding may occur due to
dispersing of hot water. Be sure to move the lift after turning the control knob to the minimum.

Never fail to ground the unit.

This unit uses a 3-con ductor power cord ( including gr ound wire). Be s ure to ground the unit for
safety.

Safety Information

Safety Precautions

Only water to be used with the Water Bath.

Only water in the W ater Bath. Probl ems can oc cur if anythin g other tha n water is us ed. Also be
sure not to heat with low water level or the bath can overheat.

Use a trap.

Use a trap when you decom press by hydraul ic rotary vacuum pump. W hen you use our Hand y
Aspirator, fill to overflow.

Maintain the vacuum seal.

The vacuum seal is expendable. Exchange the seal in case of vacuum-down.

●

You can use the vacuum seal without gr ease. But you des ire mor e longer life of the seal, put

●

silicon grease on to t he r ipped side of vac uum seal. If you are af r aid of s ample contaminat ion,
use liquid sample.

Cleaning the exterior of RE series evaporator

Do not use any volatile chem icals to clean the ext erior of th is unit. This could damage the color
and shape. Wipe clean with a soft dry towel , etc.-Do not use a brush.

If the unit is not in use for a long period of time, disconnect the power supply.

If the unit is not in use for a long period of time, turn the power off and pull out the power cord for
safety.

4. Installation/Assembly

Assembling parts

1. Set the Body at a stable place.

Be sure to set the body at a stable place.

2. Attach the motor to the body.

1. Insert the motor bearing bar into the motor support clamp of the body, put D cut surface (flat
surface) of the bar perpendicularly to either 2 upper or side screws, and fasten 4 screws tightly by
using the attached hexagonal wre nch (f or M5).

Then, slant the motor to the right (about 45°), and finger tightly the motor screw.

If you do not fasten the screws tightly, vibration may occur preventing accurate
measurements or the motor may fall causing the glass apparatus to break.

5. How To Operate

g

1. Cooling condenser

Glass A or B

●

Circulate the cooling water or alcohol in the cooling condenser.
Glass C

●

Put dry ice and pour alcohol car ef ul ly so that it does not overflow.

2. Evaporation flask

Put sample into the evaporation flask.

Fill evaporation flask to the half of it’s capacity. Liquid collected in the receiving flask

＊＊＊＊

should also be kept within approximately half capacity.

3.Water bath

Set the bath temperature at the required degree and let heat to the set point.

4. Turn the power on, and move flask down.

1. When the bath temperature re aches the set point, mak e sure that the control knob sta ys at
“min”, and turn on the power switch on the right side of control box.

If, at this time, the volume knob is not at “min”, the evaporation flask rotates when you

＊＊＊＊

turn the power on.

2. Operate the lift switch to m ove the evaporat ion flask gently into water bath, and determ ine the

adequate operational position.

5. Star t rotation.

Set the control knob at the required speed to rotate. Operate the vacuum device as well for
evaporation.

ample Feed

●●●●SSSS

Sample may be fed during operation without removing the evaporation flask.

1. Connect a teflon tube to the inlet feed cock.(id=6mm)

2. Slowly move the fed cock handle. Sample will be sucked into the flask.

6. Moving lift position

Stop rotation of motor before moving the lift. Scalding may occur due to dispersin
of
hot water.

7. End of operation

When the operation ends and you want to remove the evaporation or receiving flask , open the feed

cock to release vacuum.

8. Power failure.

The unit restarts operation once power is restored.
