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.
WARNING
Materials of the system interior include stainless
steel, brass (plating), fluorine resin, polyacetal (POM),
silicon rubber, modified polyphenylene ether (PPO),
ethylene propylen rubber (EPDM), isotropic ferrite,
ceramic, high-density carbon, special nitrile rubber
(NBR), flame-retardant PBT resin (polyethylene
terephthalate.
Always use the circulation solution that does not affect
these substances. Otherwise, these substances will
be corroded progressively, resulting in damage to the
pacts of circulation route. Do not use the ultra-pure
water or ion-exchanged water because they dissolve
CO2 gas in air to become acid, readily corroding
metals of the circulation route.
Use the circulation refrigerant that
does not affect the circulation route
material inside the unit.
CAUTION
Bore diameter of the hose joint must be
larger than 6mm. Use the hose at
appropriate length.
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. 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.

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.
