1.Safety precautions

Warnings & Cautions

Warning

Never operate the unit in an atmosphere containing flammable or explosive gas

Never operate the unit in an atmosphere containing flammable or explosive gas.

Otherwise, an explosion or a fire may result since the unit is not explosion-proof.

See section “13. List of dangerous materials” on page 23.

Be sure to connect the ground wire.

Be sure to connect the ground wire correctly. Otherwise, electrical leak may result and cause an

electrical shock or a fire.

Ban on operation when an abnormality occurs

When a smoke or an unusual odor is seen or sensed, immediately turn the ELB on the main unit

off and pull out the power plug.A fire or an electrical shock may result.

Never use electrical power cords bundled.

When these are used bundled, they might overheat causing a fire.

Take care not to damage electrical power cords.

Avoid tightly bend, pull with a strong force or twist to prevent electrical power cords from

damaging.A fire or an electrical shock may result.

Ensure sufficient ventilation when using flammable and combustible solutions.

If left at the room temperature (or below for certain solutions), flammable and combustible solutions

(ethanol, etc.) may be vaporized and thus ignited and exploded by any ignition source (switch, etc.).

Never try to disassemble or alter the unit.

Never try to disassemble or alter the unit.A malfunction, a fire or an electrical shock may result.

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.

Keep hands away from the condensate of the cooling coil and trap tank.

Condensate in the cooling coil or trap tank becomes cold during operation and for a certain period of

time after operation. If you touch it, you will suffer frost bite. Never touch the condensate.

Do not touch the condenser fin with bare hands.

Never touch the condenser fin with bare hands during maintenance. The fin has sharp edge and

may cut hands.

2.Before Use

Cautions for installation

Warning

1. Take care to select an appropriate installation site.

Avoid installing the unit, above all, in places listed below:

・Uneven or dirty floor

・Where floor is not level.

・Where temperature may change

widely.

・Where humidity is high.

・Where subject to direct sunlight.

・Place with unstable power supply.

・Where flammable gas or corrosive gas may

exists.

・Where environmental temperature is 5℃or

less or 35℃or over.

・Not well-ventilated place.

・Where vibrations are severe.

・Outdoor

Install this unit at a place with spaces shown below.

2. Installation

The unit might fall down or move by an earthquake or an impact resulting a personal injury.

We recommend making safety measures such as to avoid installing the unit at a place other

than busy places. This trap incorporates an air-cooling refrigerator, which produces waste

heat. Use the trap in a well-ventilated or air conditioned place to prevent rising of the ambient

temperature. Higher ambient temperature causes drop of operation efficiency. Moreover,

the refrigerator is put into high-temperature high-pressure operation, resulting in failure.

3. Never operate the unit in an atmosphere containing flammable or explosive

gas.

Never operate the unit in an atmosphere containing flammable or explosive gas. Since the

unit is not explosion-proof, an arc is discharged when switching “ON” and “OFF” and during

operation and a fire or an explosion may result.

Precautions when installing the unit

Caution

4. Install the unit on a level surface.

Install the unit on a level surface. If the whole bottom surface of the unit does not contact the

floor evenly, vibrations or noises may result. This might cause unexpected troubles or

malfunctions.

5. Do not install the main body in the tilted condition.

This product incorporates the refrigerator. Never transport the product with the main body

lying on its side or in the tilted condition.

6. Secure sufficient ventilation for the unit.

Do not operate the unit when its front/side panels and vent holes are blocked.

Internal temperature of the unit will rise degrading the performance and an accident, a

malfunction or a fire may result.

7. Do not operate the unit at such a place that may subject to splash.

Do not operate the unit at such a place that may subject to splash. Liquid entering the inside

may cause an accident, a malfunction, an electrical shock or a fire.

8. Never attempt reconstruction.

Never attempt reconstruction by the customer so as to prevent failure.

2. Before operating the unit

Precautions when installing the unit

Warning

9. Be sure to connect the ground wire.

・When the unit has no ground terminal, class D grounding work is necessary and please

consult your dealer or our customer service center.

・Securely connect to a distribution board or an outlet.

We recommend use of a ground type outlet

tap.

When a bipolar type outlet tap is used

2極タイプ

コンセント

Insert the ground adaptor included as an option,

into a power plug confirming the polarity of the

outlet. Connect the grounding wire (green) of the

ground adaptor to the ground terminal on the

power supply equipment.

When there is no ground terminal.

In this case, class D grounding work (100Ωor less) is necessary and please consult your

dealer or our customer service center.

Do not connect the grounding wire to any parts or lines other than a correct grounding

terminal such as a gas pipe, a water pipe or a telephone line.

Otherwise, an accident or a malfunction may result.

10.Use a dedicated outlet for the power supply.

Use a power supply that meets the electrical capacity of the unit.

Electrical capacity:：AC115V50/60Hz 5.1A

＊When the unit will not start even when you turn the refrigerator switch to “ON”, check

for abnormal main voltage or if the unit is connected to the same power supply line as

other devices and connect it to another line if necessary. Avoid using wire extensions

using a cord reel, which may result in degradation of freezing capacity or stoppage of

refrigerator from possible voltage drops. Do not connect too many wires to a single

outlet using a branching adaptor. Otherwise, a fire or an electric shock may result.

11.About handling of power cords

・Never use electrical power cords bundled. When these are used bundled, they might

overheat causing a fire.

・Do not convert, forcibly bend, twist or pull the power cord. Otherwise, a fire or an

electrical shock may result.

・Do not place the power cord under a desk or a chair, or sand between objects to avoid it

from being damaged.

Otherwise, a fire or an electrical shock may result.

・Do not place the power cord close to a stove or other heat generating device. Sheath of

the cord may burn and result in a fire or an electrical shock.

・If the power cord should be damaged (exposure of core wire or disconnection),

immediately turn the power switch of the main body off, pull off the power plug and ask

your dealer to replace the cord. If the unit is operated with a damaged power cord, a

fire or an electrical shock may result.

・Connect the power cord to an appropriate wall outlet.
