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 and take an adequate precaution to prevent the unit from
turning over. 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.
Always ground (earth) the unit 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.
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 store volatile or flammable substances in this unit if the container cannot be sealed. These
may cause explosion or fire.
Do not insert metal objects such as a pin or a wire into any vent, gap or any outlet on the unit.
This may cause electric shock or injury by accidental contact with moving 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.
Turn off the power switch (if provided) and disconnect the power supply to the unit prior to any
repair or maintenance of the unit in order to prevent electric shock or injury.
Do not touch any electrical parts (such as power supply plug) or operate switches with a wet
hand. This may cause electric shock.

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.
Never splash water directly onto the unit as this may cause electric shock or short circuit.
Never put containers with liquid on the unit as this may cause electric shock or short circuit when
the liquid is spilled.
Never bind, process, or step on the power supply cord, or never damage or break the power
supply plug. A broken supply cord or plug may cause fire or electric shock.
Do not use the supply cord if its plug is loose. Such supply cord may cause fire or electric shock.
Never disassemble, repair, or modify the unit yourself. Any such work carried out by an
unauthorized person may result in fire, or electric shock 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.
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.
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.
Disconnect the power plug when the unit is not used for long periods. Keeping the connection
may cause electric shock, current leakage, or fire due to the deterioration of insulation.
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.
Do not put the packing plastic bag within reach of children as suffocation may result.

Use a dedicated power source (a dedicated circuit with a breaker) as indicated on the rating label
attached to the unit. A branched circuit may cause fire resulting from abnormal heating.
Connect the power supply plug to the power source firmly after removing the dust on the plug.
A dusty plug or improper insertion may cause a heat or ignition.
Never store corrosive substances such as acid or alkali in this unit if the container cannot be
sealed. These may cause corrosion of inner components or electric parts.
Check the setting when starting up of operation after power failure or turning off of power
switch. The stored items may be damaged due to the change of setting.
Be careful not to tip over the unit during movement to prevent damage or injury.
Prepare a safety check sheet when you request any repair or maintenance for the safety of service
personnel.

REFRIGERATOR COMPONENTS
1. Front cover: Open this cover when connecting the remote alarm or replacing glow stater for
fluorescent lamp.
2. Control panel: The chamber temperature and alarms can be set through the keys on the control
panel. The temperature indicator and lamps are also provided on the control panel. Refer to page 11.
3. Light switch: This switch is used for turning the fluorescent lamp off and on.
4. Space for automatic temperature recorder: An automatic temperature recorder (optional
component) can be mounted here. See page 28.
5. Fluorescent lamp: 20 W lamp. See page 21 for replacement.
6. Circuit breaker (right back side): This disconnects the power when any abnormality is occurred and
over current is rushed. Rated AC 250 V, 10 A.
7. Lock: Turn the key counterclockwise through 180° to securely lock the door.
8. Glass window: The window may have condensation in high humidity environment. Wipe off the
condensation with a soft dry cloth.
9. Handle: Always hold the handle when opening/closing the door.
10. Condensation tray: The condensation on the door is accumulated in this tray. Wipe off the water
occasionally.
11. Leveling foot: Adjust the height of the leveling feet by turning the screw bolts until the unit is level.
12. Castor: When installing the unit the castors can be raised from the ground by using the leveling feet
above.
13. Shelf (MPR-721 only): Items to be stored in the chamber must be placed on the shelves. The
maximum storage weight for each shelf is 50 kg. Do not put stored items directly onto the interior floor of
the chamber. See page 15.
Drawer (MPR-721 R only): Items to be stored in the chamber must be placed on the drawers. The
maximum storage weight for each drawer is 40 kg.
14. Access port: This port allows temperature measurement cables to enter the chamber from outside.
A total of three (3) ports are provided; left side, right side and top.
15. Air exhaust vent: Do not block this vent. If this vent is blocked, temperature regulation will become
unstable. Do not place stored items in the path of the cold air.
16. Air intake vent: Do not block this vent. If this vent is blocked, temperature regulation will become
unstable. Do not insert a finger or any foreign object into this vent as there is danger from the internal fan.
17. Evaporating tray (back side): Defrost water from the evaporator accumulates on the tray and
evaporates into the atmosphere. See page 20 for cleaning.
18. Fixture (back side): These keep the adequate space between the unit and wall and also can be
used for fixing the unit. See page 13.
