Failure to observe CAUTION signs could result in injury to personnel and damage to the unit and associated property.

Symbol shows;

 this symbol means caution.

 this symbol means an action is prohibited.

 this symbol means an instruction must be followed.

Be sure to keep this manual in a place accessible to users of this unit.

< Label on the unit >

This mark is labeled on the cover in which the electrical components of high voltage are

enclosed to prevent the electric shock.

The cover should be removed by a qualified engineer or a service personnel only.

PRECAUTIONS FOR SAFE OPERATION

Do not use the unit outdoors. Current leakage or electric shock may result if the unit is exposed to

rain water.

Only qualified engineers or service personnel should install the unit. The installation by

unqualified personnel may cause electric shock or fire.

Install the unit on a sturdy floor. If the floor is not strong enough or the installation site is not

adequate, this may result in injury from the unit falling or tipping over.

Never install the unit in a humid place or a place where it is likely to be splashed by water.

Deterioration of the insulation may result which could cause current leakage or electric shock.

Never install the unit in a flammable or volatile location. This may cause explosion or fire.

Never install the unit where acid or corrosive gases are present as current leakage or electric

shock may result due to corrosion.

Use a dedicated power source as indicated on the rating label attached to the unit.

Remove dust from the power supply plug before inserting in a power source. A dusty plug or

improper insertion may pose a hazard.

Use a power supply outlet with ground (earth) to prevent electric shock. If the power supply

outlet is not grounded, it will be necessary to install a ground by qualified engineers.

Never ground the unit through a gas pipe, water main, telephone line or lightning rod. Such

grounding may cause electric shock in the case of an incomplete circuit.

Do not insert metal objects such as a pin or a wire into any vent, gap or any outlet for inner air

circulation. This may cause electric shock or injury by accidental contact with moving parts.

Never store volatile or flammable substances in this unit. This may cause explosion or fire.

Never store corrosive substances in this unit. This may lead to damage to the inner components

or electric parts.

Use this unit in safe area when treating the poison, harmful or radiate articles. Improper use

may cause bad effect on your health or environment.

Disconnect the power supply to the unit prior to any repair or maintenance of the unit in order to

prevent electric shock or injury.

Ensure you do not inhale or consume medication or aerosols from around the unit at the time of

maintenance. These may be harmful to your health.

WARNING

PRECAUTIONS FOR SAFE OPERATION

Never splash water directly onto the unit as this may cause electric shock or short circuit.

Never disassemble, repair, or modify the unit yourself. Any such work carried out by an

unauthorized person may result in fire or injury due to a malfunction.

Disconnect the power supply plug if there is something wrong with the unit. Continued

abnormal operation may cause electric shock or fire.

If the unit is to be stored unused in an unsupervised area for an extended period, ensure that

children do not have access and that doors cannot be closed completely.

The disposal of the unit should be accomplished by appropriate personnel. Remove doors to

prevent accidents such as suffocation.

Prepare a safety check sheet when you request any repair or maintenance for the safety of service

personnel.

Select a level and sturdy floor for installation. This precaution will prevent the unit from tipping.

Improper installation may result in water spillage or injury from the unit tipping over.

Connect the unit to a power source as indicated on the rating label attached to the unit. Use

of any other voltage or frequency other than that on the rating label may cause fire or electric shock.

When removing the plug from the power supply outlet, grip the power supply plug, not the cord.

Pulling the cord may result in electric shock or fire by short circuit.

Never damage or break the power supply plug or cord. Do not use the supply plug if its cord

is loose. This may cause fire or electric shock.

Do not touch any electrical parts such as the power supply plug or any switches with a wet hand.

This may cause electric shock.

Do not put a container with water or heavy articles on the unit. It may cause injury if the articles

fall. Current leakage or electric shock may be resulted form the deterioration of insulation by spilled

water.

WARNING

CAUTION

PRECAUTIONS FOR SAFE OPERATION

Do not climb onto the unit or do not put articles on the unit. This may cause injury by tipping or

damage to the unit.

Put on dry gloves when you take out refrigerated articles from the freezer. Handing frozen

contents or the inside walls with naked hands may cause frostbite.

Do not defrost inside walls using a knife or ice pick. There are pipelines for cooling behind the

walls. Be careful not to damage the lines as this could cause a breakdown. Also, do not make a

hole in the wall for installation of attachments.

Hold the handle when closing the door. This will reduce the likelihood of a trapped finger.

Disconnect the power supply plug before moving the unit. Take care not to damage the power

cord. A damaged cord may cause electric shock or fire.

Be careful not to tip over the unit during movement to prevent damage or injury.

Disconnect the power plug when the unit is not used for long periods.

Do not put the packing plastic bag within reach of children as suffocation may result

Remove dust and clean the power supply plug periodically. The operation with a dusty plug may

cause fire.

CAUTION

CAUTIONS FOR USAGE

1. Sometimes the alarm may not operate at the time of first start-up. This does not mean malfunction.

It is due to the complete discharge of incorporated battery. 2-day continuous operation of the freezer is

necessary to charge the battery fully.

2. The digital thermometer of medical freezer is designed to display the temperature of the center part of

the freezing compartment. Although the thermometer sometimes displays a temperature a little bit

higher than the actual temperature of the center part, it gradually approaches the real temperature.

3. An access port to take out the measuring cable in the case is provided on the back wall of the freezer.

Be sure to replace the cap and heat insulator after take out cable or, the inside temperature cannot

complete down, and frost may accumulate outside the port surroundings.

4. Do not use brushes, acids, benzine, thinners, powdered soap. Polishing powders, or hot water for

cleaning, as they can deteriorate the painted surfaces and parts made of plastic and rubber. Be

especially careful not to wipe plastic or rubber parts with volatile solvents such as benzine. Wipe up the

neutral detergents with a wet cloth when used.

5. Frost will accumulate on the inside walls of the freezer during use. Then remove the frost with the

spatula provided or a similar tool. Do not defrost inside walls using a knife or ice pick. There are

pipelines for cooling behind the walls. Be careful not to damage the lines as this could cause a

breakdown. Also, do not make a hole in the wall for installation of attachments.

6. The freezing temperature is different at each position inside the case of this freezer. The set

temperature represents the temperature at the center of the inside case. The refrigerated articles put on

the highest position part, are refrigerated higher than the set temperature, while those put on the lowest

part are refrigerated lower.

7. Do not put too many worm articles into a freezer compartment before enough operating. Put items in

a few at a time after the freezer compartment temperature has cooled to at least -20

8. In the case of high ambient temperature, the cabinet front may heat up after the freezer starts to

operate first. However, this does not denote a malfunction. It is due to heater or hot gas piped around

the unit frame to prevent frost and ice sticking around the cabinet.
