Handling Precautions
CAUTION!
Do not step on this unit
Do not step on this unit. It will cause injury if this unit fall down or break.
Do not place or drop anything on the unit
Do not place or drop anything on the unit. Since the unit contains precision components, it may
malfunction due to vibration, impact, etc.
During a thunder storm
During a thunderstorm, turn off the power key immediately, then turn off the circuit breaker and
the main power. If this procedure is not followed, fire or electrical shock may be caused.
Countermeasure for stop operation during night or long-term stop
In case of stopping operation during night or long-term, toggle the breaker and power switch to
"OFF".
Thoroughly wash the unit.
The unit was washed already. However, when you first use it or operate it after a long period of
deactivation, thoroughly wash it.
Circulating fluid
Specify circulating fluid upon the temperature at the time of use.
Specified temperature + 10℃ or above : Water
Specified temperature + 10℃ or below : Antifreeze solution (Nai brain
60％ or Ethylene
Glycol 50％)
• Antifreeze solution changes a condensing point according to concentration or kinds. Select
the antifreeze solution which has coagulation point at least 10 degrees lower than the
temperature at the time of use. If antifreeze solution which has higher coagulation point than
that, there is a possibility that the coolant part freezes and the heat exchange capability may
decline. Moreover, if a circulation course freezes, it may become the cause of an accident or
a failure of the equipment.
• If antifreeze solution is used for a long time, its concentration will change. If it used in such
condition, antifreeze solution may be frozen or become the cause of a failure with its strong
adhesion.
• Use distilled water or tap water for circulating fluid. Bad water in quality may cause lower
performance of pump and heater with scale accumulated. Also it may be the cause of failure.
(Well water etc.)
• If circulation solution which has large specific gravity or strong adhesion is used, the pump
gets overload and its performance may decline. (Flourinert, Galden etc.)
• Do not use things with corrosive, or things which generate corrosive substance at the time of
heating. It may become the cause of failure. (Flourinert etc.)
• Do not use what may cause damage when its steam is inhaled. (Methyl alcohol)
