START-UP OF UNIT  
Follow the procedures for the initial and consequent operations of the unit.  
1. Connect unit to dedicated power supply. Do not put any product in the unit at this time.  
2. When the power is initially applied, the audible alarm may sound. This is normal. Press the  
BUZZER key to silence the alarm. The audible 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 as outlined earlier in this manual.  
4. The unit has been factory preset to operate at 4oC±1.5oC. There is no need to set the temperature.  
5. Proper chamber temperature may take several hours to stabilize at the set point temperature. Once  
the unit has stabilized, ensure that the monitor bottle temperature agrees with the set point temperature.  
6. Turn on the light switch to ensure that the chamber light is properly functional.  
7. When you are satisfied that the unit is working correctly, begin slowly placing product into the chamber  
to minimize the temperature rise.  
Handling of containers

Note: The displayed temperature represents the temperature sensed by a thermal sensor attached to  
the monitor bottles mounted to the upper and lower portion of the chamber. The displayed temperature  
may not always be at 4oC. The chamber probes are representative and high and low average  
temperatures within the chamber.  
Defrost cycles  
There is no need for routine defrosting of the unit as this occurs automatically as follows:  
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 defrost  
heater. This will not have any discernible effect on the chamber temperature.  
2. Forced defrost  
When the ambient humidity is high, or a large amount of damp product is being stored inside the chamber,  
there is a possibility that cycle defrost may not be enough to remove all of the frost on the evaporator. In  
this case, a forced defrost cycle can be initiated. When the unit is operating under a forced defrost cycle,  
the current chamber temperature and dF is displayed alternately on the digital temperature display.  
Once the forced defrost cycle is complete, normal operation resumes. The chamber temperature of  
blood bag (400 ml) rises about 1 to 2oC during the defrosting.

calibration (zero adjustment):  
1. Remove the monitor bottle cover as shown in the figure.  
2. Remove the sensor to be calibrated from the monitor bottle.  
(Please note that model MBR-1404GR also have a sensor for  
the temperature recorder in the left side of the upper monitor  
bottle.)  
3. Prepare a bottle or beaker with a solution of crushed ice and cold water. Agitate the mixture  
thoroughly.  
4. Put the sensor to be calibrated in the mixture.  
5. While continuously agitating the ice water mixture, monitor the temperature indicated on the display of  
the sensor to be calibrated.  
6. Wait for the temperature on the display to stabilize. If the display is not 0oC calibrate using the  
following procedure. If the display does indicate 0oC proceed to step 7.  
1) Press the CAL key for approximately 5 seconds until C00 is displayed.  
2) Enter the code of the probe to be calibrated using the numerical shift key. Upper temperature sensor  
code is C01. Lower temperature sensor code is C02.  
3) Press the CAL key. This makes temperature display 0oC.  
4) The digital display will revert back to actual chamber temperature. The calibration that was entered in  
the previous step should now have an effect on the temperature display. The digital display should  
show now indicate 0.0, if not, repeat step 6.  
7. Take the sensor out of the ice water solution and wipe with a soft cloth.  
8. Attach the sensor back into the monitor bottle by reversing the procedure in steps 1 and 2.  
* For the span adjustment, contact a service personnel.
