The exhaust temperature of the
unit may exceed 60℃in certain
cases.
To keep the best performance of the product, leave
the space between product and wall, ceiling plane.
The distance between the product and wall, ceiling
plane must be longer than the one mentioned in the
right picture.
※Keep a distance of 3 cm or more between
the unit backside and the wall surface and 3
cm or more between the unit top and the
ceiling.
※The unit can be used with one of left or right
side blocked. In such an event, be sure to
keep a distance of 40 cm or more between
one of unit sides and the wall surface.
（※ For use at the room temperature of
30℃or below, the unit can be used if a
distance of 10 cm is secured between one
side and the wall surface.）
※Install the unit so that its front (with a
ventilation port) does not come under the
table.（See the table on P.10）
※With the unit installed with its side covered
40 cm under the table, the cooling capacity
is degraded by maximum 14% as compared
with the case of installation outside the
range of table.
At the -20℃setting, the cooling capacity is
degraded by maximum 25%.

4-2 Installation condition
4-1 Installation environment
Installation
●No direct sun light
●Ambient temperature must be from 5 to 35℃.
●Well-ventilated.
●No inflammable solid or liquid or gas around the unit.
●No dew condensation
●Lesser humidity and no dripping on the unit.
●Lesser dust
●Level and stable
（Check the weight of the product during operation.）
●Indoor use only
Do not place anything on top of the
product.
CAUTION
Keep enough space around the unit.
Be careful about the environment of
installation. In particular, pay due
attention on the location, air
conditioning, and ventilation.
CAUTION
Since air-cooled type refrigeration unit is
equipped with this product, heat is exhausted from
the unit.
Select the installation site that can be ventilated
well so that the ambient temperature won’t rise
because of exhausted heat. Using the product in
high ambient temperature may worsen the
operation efficiency or cooling capability. Also,
refrigeration unit will be hot and operate under
high pressure, which may cause malfunction.

4-3 Installation
(1) Unlock the lock of the stopper of the caster.
If you press and lift the lever of caster’s stopper,
lock can be unlocked (Only front two casters
have stoppers).
(2) Move the unit to the installation site.
※Traveling over steps or surface irregularities may cause
extreme impact on the casters, possibly resulting in
damage. To avoid such an event, lift up the product for
traveling.
Traveling of the unit with refrigerant left in it requires
utmost care because the adequate water level is close to
the top of the unit. In such an event, water may overflow
during traveling.
(3) At installation site, lock caster’s stopper.
Holding down the lever of caster can lock the
stopper.
(4)Put supplied caster holders (2 pieces) into the
caster to fix.
These holders fix and prevent the caster from
rotation and swiveling. Caster holder

This bracket to prevent overturning is for fixing as an earthquake countermeasure and for securing the
unit for assembling.
Fixing is made by means of bolts applied to the unit and floor surface.
※Foundation bolts (for M10) are to be provided by the customer. The bracket has not been
attached before shipment.

5-1 Preparation
Use the circulation refrigerant that does
not affect the circulation route material
inside the unit.
CAUTION
Materials of the system interior include copper
(plating), stainless steel, brass (plating), Teflon,
silicon rubber, Noryl resin, chloroprene rubber,
Duracon, and polypropylene. Always use the
circulation solution that does not affect these
substances. By nature, pure water with higher purity elutes the
material of parts in contact, and if used, may cause
troubles such as delamination of paints, pump failure,
etc. Always use either tap water or softened tap water.
CAUTION
Do not reduce the piping size or
elongate the hose for use.
Do not use the pure water
CAUTION
Operation
5
When using hose join that is not supplied with the
product, the bore diameter of the joint must be larger
than 6mm. Use the hose at appropriate length.High
piping resistance causes decrease in the circulation
rate, which in turn causes failure of sufficient mixing
inside the bath. In such an event, the cooling
efficiency may decrease and the temperature
distribution inside the bath may become
unsatisfactory. Excess load may also be applied to
the refrigerator and the circulation pump, resulting
in failure.
CAUTION
WARNING CAUTION
Use extreme caution when using
combustible or inflammable
solvent.
If you leave combustible or inflammable solvent
(ethanol and etc.) out at room temperature or higher
(lower for some solvent) , it may evaporate and catch
fire with some ignition source, and cause explosion.
Ventilate the space well while using these solvent.
Do not conduct closed operation or
idling of circulation pump.
These operation may cause malfunction. Lead the hose around while taking care
not to allow it to be buckled or crushed.
Buckled or crushed hose may cause faulty cooling of
a counterpart unit or hose disconnection from the
nozzle, resulting in water leakage.

（2) Connect hose (bore diameter: 9mm) to
external circulation discharging nozzle,
water-in nozzle, device for cooling
(closing-up style) and etc. Fix the hose
tightly with hose band so that it won’t be
slipped.
（Hose and hose band are not included.）
※Use the hose that has appropriate
withstanding pressure, heat-resistant and
appropriate material, which can not be
soaked in solvent.
Also, the material of hose should not be
bended or squashed when pulling it around
the unit.
Drainage from drain hose for tray
※Container to catch discharged
water is not included.
Check the tray regularly. Pull the handle of drain
cover softly and pick up the cover to remove it.
Then, drain away the water after removing the

When using the unit as a stand-alone low temp. bath,
Connect bypass hose to discharge and water-in

this status, stirring will be performed in the bath
and cooling capacity will be worsened.
Fix the hose tightly with hose band so that it won't be

※Use the antifreezing solution when the unit is
to be used at ＋5℃or below. Note that ethylene
glycol
or Nybrine, if used, may have the higher viscosity
within the low temperature range, resulting in
reduction of the circulation amount or activation of
the safety device of circulation pump. Never use
them at 100% concentration.
（Be sure to confirm the temperature range of
antifreezing solution because the freezing
temperature
differs depending on the concentration.）
※The use of water at the set temperatures around
＋5℃may cause freezing of the cooling coil,
resulting in deterioration of the cooling capacity.
※Make sure that there’s no foreign substance in
circulation liquid, which will cause malfunction.
（2）Make sure that water-out valve for adjusting flow
volume is closed.
（3）Set the bath cover on the main unit.
