Warning
Caution
This bath is intended for water only. Do not put
liquid other than water (i.e. oil, etc.) into this bath.
Use of liquid other than water (pure water) may cause fire or failure.
Do not put a cover on the bath.
If you use the bath with the cover, heat remains in the bath and it gets hot.
Then the cover may be melted or ignited and it may result in burn or fire.
●Specifically hot part
Do not move the bath when the liquid temperature
is high.
During use or for a certain time after use, the edge of bath and liquid
in the bath get hot. If you move the bath in such case, splashed liquid
or the edge of bath may cause scald.

Do not put the liquid other
than water into the bath.
This product is intended for water (fresh water) only.
If liquid other than water is used, it may cause fire
or failure.
(1) Raise the evaporator jack to the highest point.
(2) Place the bath so that the specimen flask of the
evaporator is at the center of the bath.
(3) Slowly lower the evaporator jack to determine a point
where the flask, the rotary joint or the joint clip does
not come into contact with the bath. (Turn the flask by
hand to make sure that it does not come into contact
with any part.)
※Do not lower the evaporator jack while the bath
handle is at the raised position.
Otherwise, the evaporation may fall or the flask
may break.
(4) Gently pour water (or hot water) in the specimen flask
to the correct level to the capacity of the flask with the
flask put in the bath.
※If water amount is excessive, water may flow over
the specimen flask while it is rotating. Keep the
water level at least 2cm below the top surface of
the bath.
(5) Raise the evaporator jack to the highest point.
※Also refer to instruction manual for rotary
evaporator (N-1300,N-1200 series).

Stop using the product if you find
any trouble.
When you face the trouble, turn off the power switch
immediately and refer to “6.Troubleshooting”on
page14
Do not touch the hot part during
use and for a while after use.
Bath and flask for specimen are in hot temperature
during use and for a while after use. Touching these
parts may burn yourself.
Completely allow the inside of the unit to dry after using water of a
temperature below the room temperature.
Use the unit under the environment below when you are going to use the unit with cool water (5℃or higher)
below the room temperature.
Completely allow the inside of the unit to dry after using cool water.
※When cool water is used, condensation water may drip from inside the unit onto the experiment table.

※About the handle
Although it is designed to be highly endurable, it might
deteriorate or break depending on the use environment.
※Water entering inside the unit may cause an electric leak or
an electric shock.
Be sure to remove the power cord before starting draining
or cleaning.
(6) When the liquid temperature in the bath has been
stable, press the power key of the evaporator to turn it
to ON, lower the jack slowly to soak the specimen
flask in the liquid.
Take extreme care not to make the liquid spill over.
When the amount of liquid is insufficient, replenish
liquid little by little taking care liquid will not spill
over the flask.
※Although the product has been designed so that
any spilled water from the bath will not enter
inside, if water should enter in the unit, an electric
leakage or an electric shock may result.
If a spill should occur, first wipe off any moisture
off the bath body, allow it to completely dry at a
well-ventilated place before attempting to use it
again. (When drying, do not place it upside down
or on its side.)
(7) Rotate the specimen flask to start condensation.
※Raise the rotation speed only slowly to avoid the
water from spilling over or ruffling.
※Take care not to burn yourself since hot water
may ruffle while the flask is rotating.
※Do not put the cover on the bath.
The cover may burn from the heater heat. And
overheating may cause inside the bath hot and a
malfunction may result.
(8) To finish operating, stop the evaporator rotation, raise
the jack, release vacuum, press the RUN/STOP key to
stop temperature control and then turn all power OFF.
