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. ■ A location with adequate ventilation Leave at least 10 cm around the unit for ventilation.
INSTALLATION 1. Removing 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.

TEMPERATURE SETTING Table 1 shows the basic operation method. Perform key operations in the sequence indicated in the table. The example in the table is based on the assumption that the freezer temperature is -20oC. Note: The unit is set at the factory that the chamber temperature -30oC. Table 1 Basic operation sequence (Example: Chamber temperature -25oC) Description of operation Key operated Indication after operation The current chamber temperature is Connect the power source and turn displayed.
REMOTE ALARM TERMINAL WARNING Always disconnect the power supply cord before connecting an alarm device to the remote alarm terminal. The terminal of the remote alarm is installed at the top of the unit. The alarm is outputted from this terminal between terminal 1 and terminal 2. Contact capacity is DC 30 V, 2 A. between COM. and N.O. between COM. and N.C. At normal Open Close At abnormal Close Open 1 2 3 Battery switch N.C. COM N.O.
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 +5oC and +15oC, and -5oC and -15oC for low temperature alarm against the chamber temperature. Note: The temperature alarm is set at ±10oC of the set temperature at the factory. Table 3.
ALARMS & SAFETY FUNCTIONS This unit has the alarms and safety functions shown in Table 4, and also self diagnostic functions. Table 4 Alarms and safety functions Alarm & Safety High temperature alarm Low temperature alarm Situation If the chamber temperature o deviates by +10 C (factory set, changeable) from setting. If the chamber temperature deviates by -10oC (factory set, changeable) from setting. Indication Alarm lamp is flashed. Temperature indicator is flashed. Alarm lamp is flashed.
DEFROSTING Use the scraper provided for removing the frost if the freezer operation must be continued. Pay attention not to impact or damage the inner wall. 1. When defrosting, move all the contents of containers in the freezer to another low temperature freezer. 2. Pressing the DEF key for more than 5 seconds to stop the refrigerating operation. While the refrigerating operation is stopped, the current chamber temperature and dF is displayed on the control panel alternately. 3.
