Be cautions, high liquid temperatures bring the rise of burns
Caution
Do not touch the sample flask or the bath when you use the product at high liquid
temperature.
Also take care of the rotation speed of the flask because of possible splashing and
burning depending on the rotation speed.
Do not touch the rotation parts while the flask is rotating
Caution
Do not touch the clip or the specimen flask while the flask is rotating. Your finger
might be caught between protruding parts and grooves of the clip and get injured.
Do not put any objects below the jack
If any objects is caught or placed between the bottom of the jack and the top
surface of the stand base, a malfunction of the unit may occur or the unit may
fall down and cause a personal injury.
Caution
Check the up/down movement range of the jack
While lowering the jack, the flask may strike against the bath and glass may
break or the unit may fall down depending on the inclination angle of the
specimen or the size of the flask used.
Use the manual slide mechanism to adjust the up/down movement range
appropriately on based on the lower limit of the jack.
Caution
※Do not put any
objects below the jack.

2. Installing the rotary joint
(1) Fit the rotary joint ring over the rotary joint.
(2) With the flask removal screw installed on the drive
body, insert the rotary joint and the rotary joint
ring altogether into the drive body.
(3) Securely insert the rotary joint until it is hooked on
the sleeve pin inside the drive assembly.
Set the rotary joint ring so that it will hook on the
inside of the flask removal screw.
※If the rotary joint is not inserted completely,
imperfect rotation, dropping of the sample flask,
or vacuum leakage may result.
(4) When you want to remove the rotary joint, turn the
flask removal screw anticlockwise, and then pull
out the rotary joint while allowing the rotary joint
ring to touch the joint.
3. Installation of the vacuum seal
The vacuum seal is an important part for the
performance of the evaporator. Take sufficient
care handling it.
(1) Holding the rotary joint so that the side on the
vacuum seal spring and the O ring are visible
toward the driver body and insert into the rotary
joint at the right angle into the housing.
※Be sure to install the rotary joint before
installing the vacuum seal.
※Verify the direction of the seal faces.
※Take care not to damage the seal lip during
washing and thoroughly dry it after washing.
※When storing, put the product in a plastic bag
to protect from external pressures.
※When you use the vacuum seal for the first time,
the unit may present an insufficient rotation
and cannot obtain sudden high rotation because
of initial tightening of the seal lip . In this case,
start with a low rotation speed and gradually
increase it.
※The vacuum seal is a consumable part.

drive may suddenly incline from the weight of the
cooler or sample flask and fall down and you might
get injured by the broken glass.
Caution
(1) Lift the jack body.
(2) Loosen the angle adjusting knob bolt to adjust the
angle while supporting the condenser with a hand.
(3) Check the vertical position of the jack and its
position relative to the bath and then securely
tighten the angle adjusting knob bolt.
6. Connecting the vacuum hose and
the coolant hose
(1) Insert the hose holder into the groove on the right
side of the jack body.
(2) Connect the condenser vacuum nozzle and the
suction port of your vacuum unit using a vacuum
hose through the hose holder.
※The vacuum hose for connecting to the vacuum
unit is not included. Check the size of the
connection nozzle and prepare a correct hose.
※Take care not to apply excessive force when
connecting the vacuum hose. The nozzle is
made of resin and may be damaged if it is
subject to an excessive force.
(3) Connect the cooler coolant nozzle and the
circulation port of you circulating chiller using a
connecting hose through the hose holder.

8. Adjusting the position of the glass trap ball
（Adjusting the manual slide）
Use both hands to lift the manual
slide slowly.
After loosening the manual slide knob bolt, the
drive body may fall down, glass may break and
result in a personal injury if you try to lift the body
suddenly.
Caution
You can adjust the manual slide assembly to a
position appropriate for the trap ball or specimen
flask sizes.
Follow the procedures below to install a trap ball
before installing the cooler.
7. Connecting the power cord
(1) Insert the power cord plug into the inlet on the
back of the stand base.
(2) Make sure that the power switch is turned OFF
and then insert the power plug into an outlet.
Be sure to lower the manual slide
slowly while supporting the driving
assembly with a hand.
When you loosen the manual slide knob bolt
suddenly, the drive may suddenly lower from the
weight of the cooler or sample flask causing the
glass to break from the shock and you might get
injured by the broken glass.
Caution
(1) Loosen the manual slide knob bolt, hold the drive
body with both hands and slowly lift it and then
tighten the manual slide knob bolt.
※Remove the cooler before attempting these
procedures.
※The internal tightening plate may come if you
loosen the manual slide knob excessively. If it
occurs, lower the slide body, align the knob
bolt with the internal plate and then tighten the
knob.
(2) Install the trap ball and the specimen flask using
the Eyela clamps.
(3) Set the bath, support the lower part of the front of
the drive with one hand, gently loosen the manual
slide knob bolt to adjust the height.
※When you loosen the manual slide knob bolt
suddenly, the drive may suddenly lower from
the weight of itself causing the glass from
shocks and you might be injured with broken
glass.
