Cautions in Using with Safety

Fundamental Matters of “WARNING!”and “CAUTION!”

WARNING!

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

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

This unit is not explosion-proof. An arc may be generated when the power switch is turned on or off,

and fire/explosion may result. (Refer to page29 “List of Dangerous Substances”.)

Always ground this unit

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

surge.

If a problem occurs

If smoke or strange odor should come out of this unit for some reason, turn off the power key right away,

and then turn off the circuit 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.

Pay special attention to the measure for flammability

and handling of flammable solvent

Leaving at the temperature higher than the room temperature may vaporize the flammable material

(ethanol, etc.). There might be the case that some flammable liquid might be vaporized at the

temperature lower than the room temperature. The result of such careless handling could cause the

fire or explosion. Do provide the vaporization with enough during the operation.

Never try to touch a hot part.

Some parts of the unit are hot during and immediately after operation. Take special care for possible

burning.

Do not disassemble or modify this unit

Do not disassemble or modify this unit. Fire or electrical shock or failure may be caused.

Cautions in Using with Safety

Fundamental Matters of “WARNING!”and “CAUTION!”

CAUTION!

When a thunder is heard

When a thunder is heard, turn the main power off immediately. A malfunction, fire or an electrical shock

may result.

Do not touch the cooling fin with bare hands

Do not touch the cooling fin with bare hands during maintenance, for the edge of the cooling fin is too

sharp to cut your hand.

Before Using this unit

Requirements for Installation

WARNING!

1. Be sure to connect the ground wire.

2. Choose a proper place for installation

Do not install this unit in a place where:

Rough or dirty surface.

Flammable gas or corrosive gas is generated.

Ambient temperature bellow 5℃or above 35C.

Ambient temperature fluctuates violently.

There is direct sunlight.

There is excessive humidity and dust.

There is a constant vibration.

Outdoor

Install this unit on a stable place with the space as shown below.

Requirements for Installation

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

Never use this unit in an area where

there is flammable or explosive gas.

This unit is not explosion-proof. An arc

may be generated when the power

switch is turned ON or OFF, and

fire/explosion may result.

To know about flammable or explosive

gas refer to page29 “List of Dangerous

Substances”.

4. Do not modify

5. Do not topple or tilt this unit

Modification of this unit is strictly

prohibited. This could cause a failure.

Set this unit to the flattest place. This

unit incorporates the refrigerator. Do

not topple or tilt it.

CAUTION!

6. Use specified receptacle for power source

Choose a correct power distribution board or receptacle that meets the unit’s rated electric

capacity.

Electric capacity:

220V AC, 50/60Hz, 7A(I include service power outlet AC100V 5A)

NOTE)

Starburst connection with a branching receptacle or extended wiring with a cord reel lowers

electrical power voltage, which may cause the degradation of refrigeration capability.

Before Using this unit

Requirements for Installation

7. Before/after installing

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, and not install to busy

place.

Though this unit has the air-cooled refrigerator, the device exhausts the heat. Do provide

the vaporization with enough so as not to raise the ambient temperature caused by the

exhaust of the heat, or install this unit with its air controlled completely. If the ambient

temperature becomes high, the operation efficiency becomes worse, and could cause the

malfunction of the device by high temperature and humidity.

8. Handling of power code

Do not entangle the power cord. This will cause overheating and possibly a fire.

Do not bend or twist the power cord, or apply excessive tension to it. This may cause a fire

and electrical shock.

Do not lay the power cord under a desk or chair, and do not allow it to be pinched in order to

prevent it from being damaged and to avoid a fire or electrical shock.

Keep the power cord away from any heating equipment such as a room heater. The cord's

insulation may melt and cause a fire or electrical shock.

If the power cord becomes damaged (wiring exposed, breakage, etc.), immediately turn off

the power at the rear of this unit and shut off the main supply power. Then contact your

nearest dealer for replacement of the power cord. Leaving it may cause a fire or electrical

shock.

Connect the power plug to the receptacl which is supplied appropriate power and voltage.

9. Before/after installing

Connect the circulation port of the main

body to the coolant device securely so

as not to leak cooling liquid.

Closing the circulation path with the

solenoid valve or throttle valve might

cause the malfunction of the pump such

as water leakage.

Please open the stop valve discharge

and the return at the time of the pump

driving by all means.

Pay attention to the over-throttle. Keep

minimum flow rate of circulating solution

more than 10% of Pump Max.Flow Rate

according to Specification Table on

page 26.

In case that there are solenoid valve on

the device to be performed the

circulation cooling, or in case that the

flow rate of the device is lower than the

1.5 liter per min. set the bypass circuit

between the main device and peripheral

devices.
