FREEZER COMPONENTS 1. Outer door: To open the door, grip the handle. On closing, make sure to lock the latch completely. 2. Magnetic door gasket: Provides a tight door seal and prevents cold air leak. 3. Inner door: Composed of separated door flaps for minimizing temperature rise when putting in and taking out refrigerated articles.
FREEZER COMPONENTS Control panel ALARM FILTER CHECK TEMPERATURE( BUZZER ALARM PV/SV BACK UP 1. Alarm buzzer stop key (BUZZER): To stop the alarm from sounding, press this key. Should a further abnormality occur, the buzzer will sound automatically. 2. Alarm test key (ALARM): Check that the alarm lamp and the buzzer functional when the freezer is operating well.
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 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.
ATTENTION The unit with CE mark is equipped with a circuit breaker on the front. Make sure this breaker is switched ON before the unit is started to run. When the operation of the unit is stopped by this breaker, contact a dealer or a service station after disconnecting the power supply plug.
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 having appropriate rating with the chamber empty, and turn on the power switch on the freezer. 2.
CHAMBER 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 the explanation based on the assumption that the temperature is –75 *The unit is set at the factory that the chamber temperature is -80 Table 1.
ALARM TEMPERATURE SETTING This unit is provided with the high temperature alarm. The setting of high temperature alarm is 10 C or C (The setting value is 2 kinds.) higher than the setting of chamber temperature. The procedure in table 2 shows the sequence to set the high temperature alarm at 15 C higher than the setting of 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. The 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 3 below. The example in the table is based on the assumption that the desired duration is 20 minutes.
REMOTE ALARM TERMINAL The terminal of the remote alarm is installed at the upper side of the unit. The alarm is outputted from this terminal. Contact capacity is 2 A (DC 30 V) - 0.1 mA (DC 1 V). a) output: normal open connectors are connected with N.O.
