PRECAUTIONS FOR SAFE OPERATION

Never damage the power supply cord or power supply plug (by breaking, adapting, placing

near a source of heat, bending with force, twisting, pulling, adding weight, or binding). A

damaged power supply cord or power supply plug may cause electric shock, short circuit, or fire.

Remove dust from the power supply plug periodically. Dust on the power supply plug may cause

insulation failure due to moisture and thus cause a fire. Disconnect the power supply plug and wipe it

with a dry cloth.

Make sure the power supply plug is pushed fully in. Faulty insertion of the power supply plug may

cause electric shock or fire due to generation of heat. Never use a damaged power supply plug or

loose power outlet.

Do not touch any electrical parts (such as power supply plug) or operate switches with a wet

hand. This may cause electric shock.

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

multiple-tap may cause fire resulting from abnormal heating.

Do not use the unit outdoors. Exposure to rain may cause leakage and/or electric shock.

Only qualified engineers or service personnel should install the unit. Installation by unqualified

personnel may cause water leakage, electric shock, or fire.

Install the unit in a location capable of bearing the total combined weight (product + optional

accessories + stored items). After installing the unit, be absolutely sure to take precautions to

prevent the unit from falling over. If the unit is installed in a location which is not strong enough or if

the proper precautions are not taken, the unit may fall over and cause injuries.

Do not install the unit in a location where flammable or volatile substances are present.

Installing the unit in a location where flammable or volatile substances are present may cause

explosions and/or a fire.

Do not install the unit where there are high levels of moisture or where it may be splashed with

water. Installing the unit where there are high levels of moisture or where it may be splashed with

water may cause the insulation to deteriorate and give rise to leakage and/or electric shock.

Be absolutely sure to earth (gound) the unit in order to prevent electric shock. Failure to earth

the product may give rise to electric shock. If necessary, ask a qualified contractor to do this work.

Do not connect the earth wire to a gas pipe, water pipe, or lightning rod when earthing

the unit. Earthing the unit improperly may give rise to electric shock.

WARNING

6

PRECAUTIONS FOR SAFE OPERATION

Never store volatile or flammable substances in this unit except in a sealed container. Such

substances may cause explosion or fire if they leak.

Never insert metal objects such as pins and wires into any vent, gap, or outlet on the unit.

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

When handling harmful samples (for example, those which consist of toxic, pathogenic, or

radioactive substances), install the unit inside a designated isolation facility. If the unit is

installed in a location which is not an isolation facility, there may be detrimental effects on both people

and the natural environment.

Before proceeding with maintenance or checking of the unit, set the power switch to OFF and

disconnect the power supply plug. Performing the work while power is still flowing to the product or

while the power supply plug is still connected may give rise to electric shock and/or injury.

Wear protective gloves and mask during maintenance. Touching or inhaling chemicals or aerosols

from around the unit may be detrimental to health.

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

Never put containers with liquid on top of the unit as this may cause electric shock or short circuit

if the liquid is spilled.

Never disassemble, repair, or modify the unit yourself. A high-voltage area is located inside the

unit. Any work carried out by unauthorized personnel may result in electric shock. Contact our sales

representative or agent for maintenance or repair.

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

operation may cause electric shock or fire.

Grip the power supply plug when disconnecting the power supply cord from the outlet.

Pulling the power supply cord may cause electric shock or short circuit.

Disconnect the power supply cord when the unit is not in use for long periods. Keeping the unit

connected may cause electric shock, leakage, or fire due to the deterioration of insulation.

Do not place this unit in a location where it is difficult to disconnect the power supply plug.

Failure to disconnect the power supply plug may cause fire in the event of a problem or malfunction.

If the unit is to be stored unused in an unsupervised area for a long period, ensure that children do

not have access and that doors cannot be closed completely.

WARNING

7

PRECAUTIONS FOR SAFE OPERATION

Ask a qualified contractor to carry out disassembly and disposal of the unit. Leaving the unit in

a location that can be accessed by third parties may result in unexpected accidents (e.g. the unit may

be used for unintended purposes).

Do not leave the plastic bags used for packing in a place where they can be reached by small

children as this may result in unexpected accidents such as suffocation.

When moving the unit, be sure to take precautions to prevent it from falling over. Moving the

unit with too much force may cause it to fall over, possibly resulting in injury. A qualified individual

must be assigned to supervise the safe movement and relocation of the unit.

Do not install the unit in a location where corrosive gases such as acids are present. Installing

the unit in a location where corrosive substances are present may cause electric components to

corrode, leading to leakage and/or electric shock due to the deterioration of insulation resulting from

corroded electrical components.

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.

Never replace the battery for the power failure alarm yourself. Only qualified engineers or service

personnel should replace the battery.

WARNING

8

PRECAUTIONS FOR SAFE OPERATION

This unit must be plugged into a dedicated circuit protected by branch circuit breaker.

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

multiple-tap may cause fire resulting from abnormal heating.

Do not climb on top of the unit or put any objects on the unit. Falling from the unit may cause

injury; falling objects may cause damage to the unit.

Never install the unit in a location where corrosive materials such as sulphur compounds are

likely to be generated (e.g. near a drainage facility). Corrosion of the copper pipes may result in the

deterioration and consequently the failure of the cooling unit.

Take care when installing the shelves or drawers. They may cause injury if they fall down.

Before resuming operation after the unit has been turned off, be absolutely sure to check the

settings. The settings may have changed as a result of stopping the unit. Items stored inside the unit

may be adversely affected if operation of the unit is resumed with changed settings.

Never store corrosive substances such as acids or alkalis in the unit except in a sealed

container. These may be detrimental to health and may cause corrosion of internal components,

cooling circuit or electrical components.

When moving the unit, contact our sales representative or agent. The moving by a user may

cause damage or injury resulting from tipping over of the unit.

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

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

To ensure the safety of the service engineer, submit a safety check sheet with the required

items filled out. This is provided as the photocopiable “Safety Check Sheet” at the end of these

operating instructions.

INSTALLATION SITE

This unit must be installed in a location which meets all the conditions described below.

If the unit is installed in a location which does not meet the conditions, its specified performance may

not be achieved or malfunctions and accidents may occur.

 A location not exposed to direct sunlight

Avoid any location which is exposed to direct sunlight. Installing the unit in a location exposed to direct

sunlight may reduce its cooling performance.

 A well-ventilated (airy) location

In order to ensure ventilation, leave clearances of at least 10 cm around the unit (at the left, right, top and

back). Blocking the ventilation may reduce the unit’s cooling performance or cause malfunctions.

 A location away from sources of heat

Avoid any location which is close to a major source of heat (such as a heater or boiler). Installing the unit

near a major source of heat may reduce the unit’s cooling performance.

 A location with minimal changes in temperature

Avoid any location where the ambient temperature is subject to sudden changes. If the unit is installed in

a location where the ambient temperature is subject to sudden changes, it will not be possible to achieve

a stable cooling performance.

 A flat surface where the floor is also capable of bearing the total combined weight (product +

optional accessories + stored items)

Install the unit on a flat surface which is even and which is capable of bearing the total combined weight

(product + optional accessories + stored items). If the unit is installed where the surface is uneven or

where the unit will be inclined at an angle, the unit will be unstable, and accidents or injuries may occur

and/or vibration or unnecessary noise may be generated.

 A location with minimal humidity

Install the unit in a location where the relative humidity is less than 80 %R.H. Installing the unit in a very

humid location may cause earth faults and/or electric shock.

 A location free of flammable or corrosive gases

Avoid any location exposed to flammable or corrosive gases. Flammable or corrosive gases can cause

explosions and/or a fire. Furthermore, corrosion of electrical parts may cause insulation to be reduced

and result in earth faults and/or electric shock.

 A location where nothing can fall onto the unit

Avoid locations where objects may fall onto the unit. Objects falling and hitting the unit may cause it to

break down or fail.

INSTALLATION

1. Preparations after unpacking

Remove all the tape used to secure the doors and interior parts, and leave the doors open for a short

while for ventilation.

If any surfaces of the outer cabinet are dirty, wipe the surface using a cloth moistened with a diluted

neutral dish-washing detergent.

Using an undiluted solution of detergent may cause the unit’s plastic areas to crack. Follow the

directions on the detergent for details of dilution.

After wiping the unit using the diluted detergent, be absolutely sure to wipe the surfaces with a cloth

dipped in clean water to remove traces of the detergent. After this, be absolutely sure to wipe the

surfaces with a dry cloth, allowing the surfaces of the outer cabinet to dry out completely, and then

proceed with the installation.

Note:

Remove the cable tie that binds the power supply cord. Prolonged contact with the tie may cause

corrosion of the cord coating.

2. Securing and levelling the unit using the levelling

feet

Rotate the front levelling feet clockwise until the casters

are raised 5 mm to 10 mm above the floor surface [Fig. 1].

In addition, rotate the levelling feet slightly clockwise or

anticlockwise, and adjust them so that the unit is

completely level.

When the casters are raised from the floor surface, the

unit will be secured. If they are left touching the floor, the

unit may accidently move when its door is opened or

closed.

3. Securing the unit by using the fixtures

Use the fixtures on the rear panel of the unit, and secure

the unit to a wall with a strong rope or chain [Fig. 2].

4. Preventing electric shock by earthing the unit

When installing the unit, be absolutely sure to earth

(ground) it. Earthing is necessary to prevent electric

shocks resulting from deterioration of electrical insulations.

This unit comes with a 3-pin plug having one earth pin.

Earthing is not required in the case of a 3-pin power outlet

equipped with an earth contact.

If the power outlet is not a 3-pin outlet equipped with an

earth contact, ask a qualified contractor to do the earthing

work.

START-UP PROCEDURE

Follow this procedure for the initial operation of the unit and for consequent operations (after temporary

stoppage for cleaning, maintenance or moving).

After a power failure, the unit will restart operation automatically with the same settings as before the

power failure [page 26].

1. Connect the power supply cord to the dedicated outlet with appropriate rating with the chamber empty.

►The alarm indicator and the chamber temperature may blink. And the buzzer may sound. In this case,

stop the buzzer by pressing the buzzer stop key (BUZZER). (This is not a malfunction.)

If the unit is unplugged or the power to the unit is interrupted, do not restart the unit for at least 5 minutes.

This protects the compressor.

Close the door securely. The door check indicator is lit when the door is open. The buzzer activates when

the door is opened for more than two minutes. The buzzer is canceled when the door is closed.

2. Allow the chamber temperature to fall to 5 oC (The chamber temperature is set to 5 oC at the factory).

Check the chamber temperature on the temperature display.

Allow the chamber temperature to fall to the set temperature when the start-up after cleaning,

maintenance or moving.

3. Switch on the light switch to check the fluorescent lamp is on. After checking, turn off the fluorescent

lamp if the light is not necessary.

4. Set the desired chamber temperature [page 19].

5. When the chamber temperature gets to the set temperature, begin slowly placing items into the

chamber to minimize the temperature rise.

Always put the stored items on the shelf (MPR-1412) or in the drawer (MPR-1412R), not on the bottom of

the chamber. Do not contact the stored items to the chamber walls.

Do not block the air intake vent nor air exhaust vent. Place the stored items with adequate space between

them to keep the cool air circulation.

The chamber temperature cannot be maintained due to the heat emission from the electrical equipment if

any electrical equipment is used in the chamber. Refer to the table below when using any equipment.

PLACEMENT OF STORED ITEMS

Do not place stored items so as to disrupt the air circulation in the chamber. Disruption of air circulation

can cause the freezing of stored items or can impair the temperature distribution in the chamber.

Air intake vent

Do not block the air intake vent with the stored items. Care should be taken not to put any paper or plastic

chips near the air intake vent. These may be sucked in and block the air intake vent.

Air exhaust vent

Do not block the air exhaust by the stored items near the air exhaust vent. Care should be taken not to

place stored items near to the air exhaust vent. The stored items may become frozen when the

refrigerator is operating at temperature settings lower than 5 oC.
