Safety Precautions

WARNING

Do not use the unit in an area where there is flammable or explosive gas.

Never use the unit in an area where there is flammable or explosive gas.

The unit is not explosion-proof. An arc may be generated when the power switch is turned on or off, and fire/explosion may result.

Always ground the unit.

Always ground the unit on the power equipment side in order to avoid electrical shock due to a power surge.

If a problem occurs, you should:

If smoke or strange odor should come out of the unit for some reason, turn off the power key right away, then turn off the earth leakage breaker and the main power. Immediately contact a service technician for inspection. If this procedure is not followed, fire or electrical shock may result.

Never perform repair work yourself, since it is dangerous and not recommended.

Do not use the power cord if it is bundled or tangled.

Do not use the power cord if it is bundled or tangled. If it is used in this manner, it can overheat and fire may be caused.

Do not process, bend, wring, or stretch the power cord forcibly.

Do not process, bend, wring, or stretch the power cord forcibly. Fire or electrical shock may result.

Do not put the power cord under the desk, chair, etc.,

Do not put the power cord under the desk, chair, etc., or through an object. Fire or electrical shock may be caused.

Do not run the power cord next to heating equipment such as a heater.

Do not run the power cord next to heating equipment such as a heater. The cover of the cord may melt and fire or electrical shock may result.

Substances that can not be used.

Never use explosive substances, flammable substances and substances that include explosive or flammable ingredients in the reservoir of the unit. Explosion or fire may occur.

Safety Precautions

WARNING

Do not disassemble or modify the unit.

Do not reconfigure the unit. Fire or electrical shock may be caused.

Do not touch the door during or immediately after operation.

Do not touch the surface of the reservoir when you run this unit at high temperature. Severe burning injury may be caused due to the high temperature.

CAUTION

During a thunder storm . . .

During a thunderstorm, turn off the power key immediately, then turn off the earth leakage breaker and the main power. If this procedure is not followed, fire or electrical shock may be caused.

Periodic check of the safety component.

The independent temperature over-rise prevention device is important safety component. Be sure to inspect it periodically. (See chapter of independent temperature overheating prevention device on P.25.)

Requirements for installation

When using

1.Always ground the unit

Connect the Unit’s power plug to a receptacle with grounding connectors.

Do not forget to ground the Unit, to protect you and the unit from electrical shock in case of power surge. Choose a receptacle with grounding connectors as often as possible.

Do not connect the grounding wire to a gas pipe, or by means of a lightning rod or telephone line. A fire or electrical shock will occur.

Grounding receptacle

If only bipolar receptacles are available for the unit, connect an optional grounding adapter to the unit’s power plug. Check the polarity of the receptacle before connecting the adapter to the receptacle. Connect the adapter’s grounding wire (green) to a grounding terminal to the power supply. Contact our sales representative in your vicinity or our service center for additional information or assistance.

Power supply plug

Bipolar receptacle

Grounding wire

Do not forget to ground the unit, to protect you and the unit from electrical shock in case of power surge.

Do not connect the grounding wire to a gas pipe, or by means of a lightning rod or telephone line. A fire or electrical shock will occur.

2.Choose a correct power distribution board.

Choose a correct power distribution switchboard or receptacle that meets the unit’s rated electric capacity.

Electric capacity BH400 : AC100V 11A , BH500 : AC100V 13A

Do not connect the unit to an outlet that differs from the above specifications because a fire or electrical shock will occur.

3.Choose a proper place for installation.

Do not install the unit in a place where:

Flammable gas or corrosive gas is generated.

Ambient temperature exceeds 35° C.

Ambient temperature fluctuates violently.

There is direct sunlight.

There is excessive humidity and dust.

There are constant vibrations.

Install the space of 15 or more in the side and the back.

Requirements for installation

When using

4.Do not remodel

The remodeling act causes the break-down.

Please never do.

5. Install the unit on a level area.

Do not installation the unit on a non level surface. This will cause hazards to the operator and create problems during actual operation.

6.After installed, you should:

It may cause injure to a person if this unit falls down or moves by the earthquake and the impact, etc..

To prevent, take measures that the unit cannot fall down.

7.When you use the liquid and cooling water:

Do not use the liquid with the explosion and toxicity.

Do not let cooling flow to the cooling coil when working at high temperatures.

Do not mix water when you use oil in the reservoir.

Precautions in handling

8. When you need circulation:

Detach flexibility pipe or fitting for

 

 

the short-circuit and install the

 

 

attached hose joint when you

 

 

need to circulation at a distance.

Fitting

hose joint

Connect a hose with the hose

 

 

joint and secure them with hose

 

 

clamps not to leak water. When

 

 

using silicon oil, select a hose to

 

 

resist silicon oil (e.g. fluorine

 

hose

rubber).

Flexibility pipe for the short-circuit

 

9.When you use liquid, you should

The liquid poured into the examination tank must use water or the silicon oil.

It evaporates for water and alcohol, etc. while using .Replenish sometimes.

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.

Precautions in handling

10.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 may be caused.

Do not touch the upper surface in the reservoir when working at the high temperature. Failure to observe this caution may cause scald.

11.Confirmation of safety

Turn on the earth leakage breaker.

Pour the liquid (water) into the reservoir tank.

Water level should be 3 5 cm below the upper

edge. When circulated at a distance, the water level will go down. Pour the water again into the reservoir to be a fixed water level.

Be sure whether independent tempera-ture overheating prevention device is set in a

temperature which is 15 or more higher than the temperature of the tank used. (BH500)

Stabilize by using stopper in the bottom in the reservoir when you use the throw type cooling device together.
