FREEZER COMPONENTS 1. Door: To open the door, grip the handle. 2. Handle: Always grip this handle to open and close the door. 3. Lock: Turn counterclockwise to 180 with a key and the door is securely locked. 4. Access port: This is used for leading the measuring cable from the chamber to the outside. 5.
FREEZER COMPONENTS Control panel 1. Alarm lamp (ALARM): This lamp is flashed when unit is in alarm status. See page 18. 2. Digital temperature indicator: Normally, the current chamber temperature is displayed. In alarm status, an error code and chamber temperature is displayed alternately. See page 18. 3.
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 Do not install the unit under direct sunlight. Installation in a location subjected to direct sunlight cannot obtain the intended performance.
INSTALLATION 1. Removing the packaging materials and tapes Remove all transportation packaging materials and tapes. Open the door 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.
START-UP OF UNIT Follow the procedures for the initial and consequent operations of the unit. 1. Turn the power switch ON with the chamber empty. 2. Turn ON the battery switch. 3. Set the chamber temperature to a desired value. 4.
CHAMBER TEMPERATURE SETTING Table 1 shows the basic procedure for setting the chamber temperature. Perform key operations in the sequence indicated in the table. The example in the table is based on the assumption that the desired temperature is -25 Note: The unit is set at the factory that the set temperature -30 Table 1.
ALARM TEMPERATURE SETTING This unit is provided with both high and low temperature alarms. The temperature at which the alarm is activated may be changed. The available set range for high temperature alarm is between +5 C and +15 C, and -5 C and -15 C for low temperature alarm against the chamber temperature.
SETTING OF ALARM RESUME TIME The alarm buzzer is silenced by pressing alarm buzzer stop key (BUZZER) on the control panel during alarm condition. The alarm buzzer 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 5 below. The example in the table is based on the assumption that the desired duration is 20 minutes.
CHANGE OF COMPRESSOR DELAY TIME The compressor delay time can be changed to reduce the load on the power line and to facilitate the start-up (resume) of the freezer after power failure. The example in the table is based on the assumption that the delay time is changed to 4 minutes. (The delay time is set in 3 minutes at the factory.) Note: The set range for delay time is between 3 and 15 minutes.
ALARMS & SAFETY FUNCTIONS This unit has the alarms and safety functions and also self diagnostic functions shown in Table 7. Table 7. Alarms, safety functions and self diagnostic functions Alarm Situation Indication Buzzer Safety operation If the chamber temperature is higher Alarm lamp is flashed.
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.
TROUBLESHOOTING Malfunction Check/Remedy The circuit breaker of power source is active. The chamber is not cooled The voltage is too low. (In this case, call an electrician.) at all The power switch is not ON. The large amount of articles (load) is stored in the chamber at one time.
DISPOSAL OF UNIT WARNING If the unit is to be stored unused in an unsupervised area for an extended period ensure that children do not have access and door cannot be closed completely. The disposal of the unit should be accomplished by appropriate personnel. Always remove lids to prevent accidents such as suffocation.

TEMPERATURE RECORDER (OPTION) Starting recording and setting the time: Turn the power switch ON. The ink pen will move inward on the circular recording paper and stop temporarily at the Ink pen 0% position (equivalent to the 40 C line). Then the ink pen will move to the position which indicates the measured Hour temperature.
INTERFACE BOARD (OPTION) The temperature log of our medical equipment can be loaded into a personal computer by using the combination of optional interface board (MTR-480) and data acquisition system (MTR-5000). For the loading, RS-232C is needed to connect our medical equipment with a personal computer. The combination of optional LAN interface board (MTR-L03) and data acquisition system (MTR-5000) enables the equipment monitoring (such as chamber temperature) by connecting our medical equipment with the data acquisition system (MTR-5000) with LAN.
