PRECAUTIONS FOR SAFE OPERATION It is imperative that the user complies with this manual as it contains important safety advice. Items and procedures are described so that you can use this unit correctly and safely. If the precautions advised are followed, this will prevent possible injury to the user and any other person. Precautions are illustrated in the following way: WARNING Failure to observe WARNING signs could result in a hazard to personnel possibly resulting in serious injury or death.
PRECAUTIONS FOR SAFE OPERATION WARNING 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. unqualified personnel may cause electric shock or fire. The installation by Be sure to 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.
PRECAUTIONS FOR SAFE OPERATION WARNING Always 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. Never splash water directly onto the unit as this may cause electric shock or short circuit. Never disassemble, repair, or modify the unit yourself.
PRECAUTIONS FOR SAFE OPERATION CAUTION 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. Fix the shelves securely. Incomplete installation may cause injury or damage.
CAUTIONS FOR USAGE 1. 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. 2. This inner cabinet is refrigerated by the forced circulation of cooled air inside the chamber. Ensure that the intake and exhaust vents are not blocked. Adequate space should be provided between the items inside the unit to allow air circulation.
CAUTIONS FOR USAGE 13. Do not clean the unit with scrubbing brushes, acid, thinner, solvents powdered soap, cleanser or hot water. These agents can scratch the paint or cause it to peel. Plastic and rubber parts can be easily damaged by these materials. Especially never use any volatile solvent to clean the plastic or rubber parts. When a neutral dishwashing detergent is used to clean the unit, wipe it up thoroughly with a cloth soaked in clean water. 14.

REFRIGERATOR COMPONENTS 1. Glass window: Water can sometimes condense on the glass in areas of high humidity. Wipe off the condensation with a dry soft cloth. (MPR-414FS has no glass window.) 2. Magnetic door gasket: This prevents the cool air from escaping. Always keep clean. 3. Control panel: The operation status is displayed on this panel. And the temperature setting is available through this panel. Refer to page 10 for the details. 4.

INSTALLATION Installation site To operate this unit properly and to obtain maximum performance, install the unit in a location with the following conditions: 1. A location not subjected to direct sunlight Installation in a location subjected to direct sunlight may lead to inadequate cooling. 2. A location with adequate ventilation Leave at least 10cm around the unit for ventilation. Poor ventilation will result in a reduction of the refrigeration capacity. 3.
INSTALLATION Installation 1. Remove the packaging materials and tapes Remove all transportation packaging materials and tapes. Open the doors and ventilate the unit. If the outside panels are dirty, clean them with a diluted neutral dishwashing detergent. (Undiluted detergent can damage the plastic components. For the dilution, refer to the instruction of the detergent.) After the cleaning with the diluted detergent, always wipe it off with a wet cloth. Then wipe off the panels with a dry cloth.
OPERATING INSTRUCTIONS Temperature setting Table 1 shows the basic operation method. Perform key operation in the sequence indicated in the table. The example in the table is based on the assumption that the refrigerator temperature is 4oC and the freezer temperature is -25oC. Note: The unit is set at the factory so that the refrigerator temperature is 5oC and the freezer temperature is -20oC.
OPERATING INSTRUCTIONS Key lock operation This unit incorporates a key lock feature which can inhibit the tampering using the keys on the control panel. The key lock is set to OFF at the factory. Display L0 L1 Mode Key lock OFF Key lock ON Function Temperature change enabled Temperature change disabled Table 2 Key lock setup procedure (Example: Key lock OFF ⇒ Key lock ON) Operation Key operated Press and hold the digit shift key for about 5 seconds.

ALARMS AND SAFETY FUNCTIONS This unit has the alarm and safety functions shown in Table 5, and also a self diagnostic function. Table 5 Alarms and safety functions Kind of alarm Situation or safety High temperature alarm Over-heat protector Low temperature alarm Over-cool protector Power failure alarm Door alarm Auto return Key lock • Refrigerator If the chamber temperature exceeds the set temperature. • Freezer If the chamber temperature exceeds the set temperature.
SETTING OF ALARM RESUME TIME The alarm buzzer and remote alarm are silenced by pressing BUZZER key on the control panel during alarm condition. The buzzer and remote alarm will be activated again after certain suspension if the alarm condition is continued. The suspension time can be set by following the procedure shown in the Table 6 below. The example in the table is based on the assumption that the desired duration is 20 minutes. Note: The duration is set in 30 minutes at the factory.
DEFROSTING Refrigerator The following 2 kinds of defrost methods are adopted for the refrigerator, which control defrosting automatically. 1. Cycle defrost To keep the temperature stable inside the chamber, the refrigeration compressor is cycled on and off. During “off” periods any frost which has accumulated on the evaporator is melted by energizing a heater. This will not have any discernible effect on the chamber temperature. 2.
MAINTENANCE WARNING Always 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. Cleaning • Clean the unit once a month. Regular cleaning keeps the unit looking new. • Use a dry cloth to wipe off small amounts of dirt on the outside and inside of the unit and all accessories.
