TROUBLESHOOTING

If the unit malfunctions, check out the following before calling for service.

The chamber is not cooled at all

1.The circuit breaker of power source is active.

2.The voltage is too low. (The status code “--2” is displayed. See page 22.) In this case, call an electrician.

3.The power switch is not ON.

4.The large amount of articles (load) is stored in the chamber at one time. (The status code “--3” is displayed. See page 22.)

The cooling is poor

1.The ambient temperature is too high. (The status code “--1” is displayed. See page 22.)

2.The latch of inner door is not closed completely. The outer door is not closed firmly. (The frost or ice between the cabinet and door gasket possibly prevents door seal.)

3.The air intake vent is blocked.

4.The condenser filter is clogged. Always clean the filter when the filter check lamp is lit.

5.The set temperature is not inputted properly.

6.The freezer is not away from the direct sunlight.

7.There is any heating source near the freezer.

8.A rubber cap and insulation for the access port are not set correctly.

9.You put too many unfrozen articles into the freezer compartment.

Alarm test key cannot actuate the alarm

The alarm is activated only when the power switch is ON.

1.The nickel-metal-hydride battery has been discharged entirely. In this case, operate the freezer for about 3 hours and depress the alarm test key again. Entirely discharged cell requires about 2 days’ operation of the freezer.

2.When only the buzzer or only the alarm is actuated by the alarm test key, the unactuated part is out of order, and must be replaced.

Noise

1.The freezer is not installed on the sturdy floor.

2.The freezer is not leveled with the leveling feet.

3.There is anything touching the frame.

4.The freezer is in the status immediately after start up.

The unit sometimes causes a noise when the chamber temperature is high due to the large load. The noise gets less and less accompanying with the cooling of the chamber.

Back-up test switch does not operate normally (if the back-up system is provided)

1.The liquid carbon dioxide tank is empty.

2.The valve of the carbon dioxide tank is not opened.

3.The ambient temperature is too high. In this case, move the tank to a cool location.

Inquire at liquid carbon dioxide suppliers about its installation, removal, adjustment, and examination.

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 doors cannot be closed completely.

The disposal of the unit should be accomplished by appropriate personnel. Always remove doors to prevent accidents such as suffocation.
