5-1 Preparation
Warning
Use extreme caution when using
combustible or inflammable solution.
If you leave combustible or inflammable solution
(methanol and etc.) out at room temperature or
higher (lower for some solutions) , it may evaporate
and catch fire with some ignition source, and cause
explosion. Ventilate the space well while using these
solutions.
1 Connecting pipes and hose
1)Loosen nut for fixing nozzle and make sure
that o ring is fixed at the slot for fixing o ring.
2)With holding nozzle with your hands, tighten
the nut so that the water won’t be leaked.
3)Connect hose (Diameter: 9mm) to external
circulation nozzle (IN & OUT) and the device
to be cooled down. Attach hose band to fix the
hose (hose and hose band are not supplied
with the product).
※Do not jack up the nozzle too much.
※Do not change the direction of nozzle during
operation to prevent damage or leak.
※Material of the hose must have appropriate
pressure and fever-resistance and it must not
be affected by any solutions. Also, make sure
that hose is not bended or crashed when using
the unit.
Caution
Use circulation liquid that does
not affect the material of
circulation route inside the unit.
Materials used for the circulation route are
copper, stainless, brass, fluorine resin, polyacetal,
silicon rubber, polyphenylene ether, ethylene
propylene rubber. Use circulation liquid that does
not affect these materials. Or some parts in the
circulation route may be damaged. Also, do not
use extra-pure water or ion exchange water.
These water may solve carbon dioxide in the air
and generate acid solution, which may corrode
the metal of circulation route.
Caution
Use the hose at appropriate
length.
Use the hose at appropriate length.
When the piping resistance is strong,
cooling capability or temperature distribution
in the circulation bath will be worsen
because of small quantity of circulation water.
Caution
Do not conduct closed operation
or idling of circulation pump.
These operation may cause malfunction.

2. Filling cooling water
1)Make sure that drain plug is connected to
drain hose.
2)Fill the water in the bath up to the position
where cooling coil is fully filled (CCA-1112A：
Approx. 2.7L).
※Use anti-freeze liquid, if you use the unit at ＋7℃
or lower. However, if you use ethylene glycol or
Nybrine, the viscosity will be higher in low
temperature, which makes temperature
distribution in the bath worse.
In such a case, mix the moderate amount of
water ( Make sure the freezing temperature when
the liquid is concentrated.)
※Make sure that there’s no foreign substance
in circulation liquid, which will cause malfunction.
3) Set the bath cover on the main unit.
3.Connecting power plug
Make sure that residual current device and power
switch are turned off before connecting power
plug to outlet.
Caution
Do not get control panel wet.
When filling water into the bath, do not get control
panel wet. It will cause malfunction in controlling
portion or electric shock hazard because of
electric leakage.
※The unit is coated with ABS (control panel),
polyphenylene ether (bath cover), polyacetal
(nozzle and drain plug) and nitrile rubber (tray).
(These are nonferrous materials). Compared to
metals, these plastics and rubbers can be
easily discolored, deformed and damaged by
heat, light (example: direct sun), solution
(example: circulation liquid, cleanser) and
forces (impact). So use caution when handling
the unit.
Do not use pure water
Use tap water or softened tap water.
Do not use pure water or ion exchange water.
These types of water solve carbon dioxide in
the air into acid solution, which could corrode
the metal of circulation route.
Also, pin hole of cooling coil or circulation
pump may be impaired because of the use of
these water.

※Each time you press［▲］or［▼］key, the
temperature changes by 1℃and holding down
the key for longer can change the value
continuously.
3) Determining setting temperature
Press［Set］key. Displayed setting
temperature (blinking) is determined and
indicator changes to display measured
temperature (measuring mode) .
※If no key operation is done for longer than 5
seconds, changed preset temperature can not be
determined and indicator changes to display
measured temperature (measuring mode). In such
a case, please reset from 1).

5-3 How to use optional accessories
5-3-1. How to use stop valve Caution
Use the hose at appropriate
length.
Use the hose at appropriate length.
When the piping resistance is strong,
cooling capability or temperature distribution
in the circulation bath will be worsen
because of small volume of circulation water.
5-3-2. Stainless steel tank lid.
When circulating volatile liquid such as methanol
as circulation liquid, it should be used. The tank
lid attached as standard accessory is a plastic and
the condition becomes bad for a solvent-resistance
and the weather resistance compared with metal
tank lid.
* The material is SUS304.
If the flow volume is not enough, use the
bigger diameter nozzle (Optional accessory)
to reduce the load in circulation pipes.
Please use the insulated hose set (Optional
accessory) in order to avoid the condensation
of water on the surface of pipes.
* Use the hose at appropriate length and
diameter.
* The material of hose is Polychloroprene.
