3. How to Use
3.3 Before use
-Connect the power cable on the bottom of the main body and turn ON the power switch on
the left bottom of the front side of the product.
-The main body is packed with the maximum height. If the product is powered on without
the maximum height, it goes up to the maximum height automatically.
-When the product is powered off, it automatically goes up to the maximum height to protect
a specimen.
-After putting together the flask and accessories, pull the angle control knob and then adjust
the flask at a proper angle. After that, release the knob and check its fixture.
-Make sure to stop rotating the flask before adjusting its angle.
-Adjust the flask’s height with Lift Height Control Button on the bottom of the product.
※See “②Lift Height Pre-Limit Mode” to set the maximum height to prevent glass
components from being damaged.
-Make sure to put the flask in fluid of Bath and then rotate it. Otherwise, the flask’s weight
can give a burden to the neck of the flask and thereby is likely to damage the flask.
-To a large evaporating flask with 3 liter and more, make sure to separate the flask after using
the product. The neck’s load can damage glass.
-Fill the evaporating flask less than 50% with solution. Otherwise, the solution can overflow.
-Select the position and size of Bath properly
in line with the evaporating flask’s size.
-The glass component damaged in use is not applied
to warranty service.
3.4 How to use the main body
①How to adjust the flask’s angle
1) Pull the flask angle control knob and set a proper angle.
After that, release the knob.
(10 steps available)
2) At this time, place the flask angle control knob
in its right position in order to fix the angle.
Check the knob’s position to the end.
3) The weight of the assembled glass parts makes it possible
to move suddenly when the knob is pulled out.
Pull

②Lift Height Pre-Limit Mode
1) When the main body is powered on first, “FREE” is displayed on the top LCD. It is possible to
go to Height Pre-Limit Mode of Lift. This mode is used to prevent the flask and vapor duct
from being damaged by poor operation of the product.
The minimum height to prevent the evaporating flask and vapor duct from being damaged is
set already in line with Heating Bath’s size. Therefore, they do not go down to the height lower
than the set height.
2) If the knob is turned clockwise when FREE is displayed, the display value is changed in the
order of 3bL -> 5bL -> FREE. If turned counterclockwise, the display value is changed in the
reverse order. If Jog-Dial knob is pushed long at a proper display value, the value flickers and
is saved. After the product is turned off and then on, the set value is set the saved one.
(1) ‘FREE’ mode: Adjustable in the range of 0~200mm without height limit
(2) ‘3bL’ mode: based on the basic components ’2.5Lit Heating bath and 2Lit flask’
-. Pre-limit height: 45mm
(3) ‘5bL’ mode: based on the basic components ’5.5Lit Heating bath and 5Lit flask’
-. Pre-limit height: 60mm
③User Height Pre-limit Mode
1) Aside from the default set ‘Free’, ‘3bL’, or ‘5bL’ mode, a user is able to set up the minimum
height limit.
2) By pushing and releasing mode button and Jog-Dial knob at the same time, it is possible to go
to Save Flask Height Mode.
However, in Locking mode, Jog-Dial knob does not work. Therefore, it is impossible to go to
Save Flask Height Mode.

3) Set a proper height with the use of Jog-Dial knob and then push long Jog-Dial knob. The set
value flickers and the height is saved. In this case, the height is not set to the one lower than
the value set in Height Pre-limit Mode. If you want to set a height lower than the set value,
change the mode to ‘FREE’ to set the value again.
4) After the setting is complete, push the mode button once. Now, you can escape from Save
Height Mode.
④Lift Height Control
1) It is possible to adjust Lift’s height
with the use of UP & DOWN buttons on the bottom.
2) Push long Lock button. The button’s red light is on.
Now, Height Lock mode is set up.
In this mode, the current height is fixed.
Arrow UP & DOWN buttons do not work.
3) Push long Lock button again. The button’s Red light is off. Height Lock mode is released.
⑤Rotary Speed Setting
1) In Set Lift Height Limit Mode, push the mode button once. It is possible to go to Set Rotary
Speed Mode.
2) If the arrow on the left bottom of LCD flickers, turn Jog-Dial knob to set a rotation direction.
means clockwise turn, and means counterclockwise turn.
3) After rotation direction is set up, push the mode button to set a RPM value.
If a SV(Set Value) value on the bottom of LCD flickers, turn Jog-Dial knob to set a RPM
value.
It is possible to set it up to 300RPM.
4) After the setting is complete, push Jog-Dial knob once. The flask starts to rotate and
Icon is displayed on LCD. The current RPM value is displayed on the top `PV(Present
Value)’.
5) If Jog-Dial knob is pushed once in rotation, the rotation process stops.
