Warning
1. About the use of the liquid and cooling water
„ Please do not use the liquid with the explosion
and toxicity.
„ Please do not mix water when you use oil in
the examination tank. (BH400/500)
„ Please do not flush cold water when using at
high temperatures. (BH400/500)
Caution
1. Please do the method of installing the hose correctly.
„ Please detach flexibility pipe or nipple for the
short-circuit and install the attached hose
entrance when using as a circulation tank.
Securely connect to prevent water leak. When
using silicon oil as bath liquid, select a hose
resistive to silicon oil (e.g. fluorine rubber).

„ The liquid poured into the examination tank
must use water or alcoholic solution.
(BH200/300)
„ The liquid poured into the examination tank
must use water or the silicon oil. (BH400/500)
„ It evaporates for water and alcohol, etc. while
using .Please replenish sometimes.
„ Please use the ethyl alcohol solution about
alcohol .Be careful please not to freeze
referring to a right table in proportion to the
service temperature. Do not use neither
automotive antifreeze nor the ethylene glycol
liquid. (BH200/300)
„ Using well water or bad-quality water will cause
accumulation of scale and copestone on the
heater pump, etc. Be sure to use distilled water
or pure water to prevent performance
deterioration or malfunction.
„ The viscosity must use the one to 50CST at
80 ℃ or more about the silicon oil.
3. Attention in handling
„ Please do not sprinkle water on the control part
and the operation panel. When water splashes
to an internal electrical component, the leak
and the electric shock are caused.
„ The upper surface in the tank etc. become
high temperatures, too, when using at the high
temperature. Please note handling enough.
