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 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.

Substances that can not be used.

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

Do not disassemble or modify the unit.

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

REQUIREMENTS FOR INSTALLATION

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 explosionproof. An arc may be generated when the power switch is turned ON or OFF, and fire/explosion may result.

Always ground the unit.

Connect HC200’s power plug to a receptacle with grounding connectors.

Do not forget to ground HC200, 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.

100V receptacle with grounding terminals

Power plug

If only bipolar receptacles are available for HC200, connect an optional grounding adapter to HC200’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.

100V bipolar receptacle

Grounding wire

Choose a correct power distribution board or receptacle.

Choose a correct power distribution board or receptacle that meets HC200’s rated electric capacity.

Electric capacity : 100 VAC, 3A

Do not connect HC200 to an outlet that differs from the above specifications because a fire or electrical shock will occur.

Install on a level area.

• Do not installation HC200 on a non level surface. This will cause hazards to the operator and create problems during actual operation.

Choose a proper place for installation.

Do not install HC200 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 is constant vibrations.

• Keep the following clearance around HC200.

Caution

Handling of power code.

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. Fire or electrical shock may result.

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. The cover of the cord may melt and fire or electrical shock may result.

When the power cord is damaged (exposure of the core wires, disconnection, etc.), turn OFF the power key right immediately, then turn OFF the circuit breaker and the main power. Contact customer service for a replacement immediately. If this procedure is not followed, fire or electrical shock may be caused.

Wipe off the condensation

The condensation may appear on aluminum block when temperature rises after a cooling device works. Wipe off the condensation with a cloth in that case.

Install an aluminum block

Install an aluminum block correctly in the depression of main unit.

SELF-DIAGNOSTIC FUNCTIONS

HC200 has self-diagnostic functions. Whenever there is a problem in operation or system performance, the sub display on the control panel flashes an abbreviation of the problem and its corresponding error code, while HC200 sounds an alarm buzzer. If this happens, check the error code on the display and shut down HC200 immediately.

FIXED TEMPERATURE OPERATION

Start up

After setting up HC200, follow the procedure below to start operation

NOTE: When turned on power, HC200 will automatically select the behavior in accordance with the following cases.

When you use HC200 for the first time:

When stopped by using the abort function:

When stopped during the program operation and the quick auto-stop operation with the resume function inactive: ( is set to off )

When you turn on the power switch, HC200 automatically selects the fixed temperature operation mode and is in standby condition. The main display shows the latest measured temperature, while the sub display shows the previously preset temperature.

The STANDBY lamp lights up and the FIXED TEMP lamp starts flashing.

When turned off power during the Fixed temperature operation:

When you turn on the power switch, HC200 automatically starts the fixed temperature operation toward the temperature that has been set before turning off. The main display shows the latest measured temperature, while the sub display shows the previously preset temperature.

The FIXED TEMP lamp is lit.

When changing the set temperature, see “Changing Preset Temperature during Operation” on page 11.

When stopped during the program operation and the quick auto-stop operation with the resume function activated: ( is set to on)

When you turn on the power switch, HC200 automatically starts the fixed temperature operation toward the preservation temperature that has been set before turning off. However, in case of the quick autostop operation, HC200 starts the quick auto-stop operation from the first in the condition that has been set before a black out. The main display shows the latest measured temperature, while the sub display flashes

The PROGRAM lamp is lit.

When changing to the fixed temperature operation, bring HC200 to the standby condition in the fixed temperature operation by pushing the MENU key.
