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 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 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 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 (MBR-304D, MBR-304G). Incomplete installation may cause injury or damage. 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.
CAUTIONS FOR USAGE • 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. • 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.
ENVIRONMENTAL CONDITIONS This equipment is designed to be safe at least under the following conditions (based on the IEC 1010-1): 1. Indoor use; 2. Altitude up to 2000 m; 3. Ambient temperature 5oC to 40oC 4. Maximum relative humidity 80% for temperature up to 31oC decreasing linearly to 50% relative humidity at 40oC; 5. Mains supply voltage fluctuations not to exceed ±10% of the nominal voltage; 6. Other supply voltage fluctuations as stated by the manufacturer. 7.

REFRIGERATOR COMPONENTS 1. Door switch: To detect the door status (open/close). 2. Battery switch: ON-OFF switch for built-in battery for power failure alarm. Always turn on this switch when the refrigerator is operated. Turn off this switch when the refrigerator is not used for long period to protect the battery. 3. Power switch: Main switch of the unit. 4. Glow starter: For a fluorescent lamp. It is recommended to replace the glow starter at the time of replacement of fluorescent lamp.
REFRIGERATOR COMPONENTS Control panel and keypad 7 8 9 1 2 1. Alarm buzzer stop key (BUZZER): 10 3 11 4 5 6 To silence the audible alarm, press this key. 2. Temperature display key (UPPER/LOWER): By pressing this key, the displayed temperature is changed; upper monitor bottle temperature, lower monitor bottle temperature, and average temperature of upper and lower monitor bottles are displayed in sequence. 3.
INSTALLATION Installation site To operate this unit properly and to obtain maximum performance, install the unit in a location with the following conditions: • A location not subjected to direct sunlight Installation in a location subjected to direct sunlight may lead to inadequate cooling. • A location with adequate ventilation Leave at least 10 cm around the unit for ventilation. Poor ventilation will result in a reduction of the refrigeration capacity.
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. 2.
BEFORE COMMENCING OPERATION Preparation of monitor bottle Prior to the operation of the unit, fill the monitor bottles (upper and lower) with 10% glycerol or water using the following procedure: Recorder sensor (lower bottle of MBR-304G and MBR-304GR) Temp. sensor 1. Remove the top and bottom drawer (or shelf). 2. Remove the monitor bottle cover as shown in the figure 1. 3. Take out the sensor from the monitor bottle. 4. Remove the fixing screw and take out the monitor bottle. 5.
BEFORE COMMENCING OPERATION Remote alarm terminal The terminal for remote alarm is installed inside the rear cover of the unit. The alarm is outputted from this terminal. The contact rating is DC 30V, 2 A. Contact output: At normal condition “Open” At abnormal condition “Close” Note: The contact is “Close” because it is regarded as abnormal when the power supply cord is disconnected from the outlet or the power switch is turned off, or in the event of power failure.
START-UP OF UNIT Follow the procedures for the initial and consequent operations of the unit. 1. Connect the power cord to the dedicated outlet with appropriate rating. 2. On start-up, the alarm buzzer sometimes operates. In this case, stop the buzzer by pressing the buzzer stop key (BUZZER). The alarm will operate until the temperature monitor bottle sensor goes into the range of 4oC±2oC. 3. Ensure that both monitor bottles have been filled with 10% glycerol or water as outlined on page 13. 4.
OPERATING INSTRUCTIONS Storing of items Do not disturb the air circulation in the chamber by the stored items. The disturbed air circulation can cause the freezing of stored items or degrade of temperature distribution in the chamber. Air-intake vent Do not block the air-intake by the stored items near the air-intake vent. Take should be taken not to put any paper or plastic chips near the vent. They may be vacuumed up and block the vent.
OPERATING INSTRUCTIONS Temperature display The unit is set at the factory to obtain the proper temperature automatically (4oC±1oC). There is no need to set the temperature.

Table 2 Alarms and safety functions Alarm & Safety High temperature alarm Low temperature alarm Protection of excessive high temperature Protection of excessive low temperature Situation If the upper or lower temperature sensor o senses a temperature ≧ 6 C. If the upper or lower temperature sensor o senses a temperature ≦ 2 C.
ROUTINE 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 of cabinet • Clean the unit once a month. Regular cleaning keeps the unit looking new.
ROUTINE MAINTENANCE Replacement of glow starter A glow starter is located upper right side of the cabinet.. 1. Disconnect the power supply plug. 2. Remove the glow starter and replace with a new one. Glow starter 3. Replace the water-proof rubber. Cleaning of condenser filter This unit is provided with the condenser filter at the bottom of the cabinet. Clean the filter once a month even since a clogged filter may cause shorter compressor life as well as the poor cooling.
