CALIBRATION
During continuous operation, the following service tasks must be performed:
• Perform a temperature calibration at least once a year.
For temperature calibration, contact our sales representative or agent.
REPLACEMENT OF WORN-OUT PARTS
Replacement of the battery for the power failure alarm
Replace the battery for the power failure alarm about every 3 years to ensure the alarm will operate in the
event of a power failure. Contact our sales representative or agent to arrange the replacement of the
battery.
■
The alarm function (blinking of alarm indicator, sounding of buzzer) will not operate when the battery for
the power failure alarm is flat.
■
The alarm indicator blinks and the buzzer sound as a result of power from the battery for the power
failure alarm. The regular replacement of the battery for the power failure alarm is important to prevent
an increase in chamber temperature in the event of unexpected circumstances.
<Important>
The used battery is a recyclable resource. Do not dispose of the battery. Always follow the procedure
for recycling.
Replacement of the fan motor
Replace the fan motor for the cooling circuit about every 6 years to ensure the appropriate operation of the
freezer. Contact our sales representative or agent to arrange the replacement of the fan motor for the
cooling circuit.
■
The appropriate operation of the unit is maintained by cooling the compressor with a fan. The motor to
operate the fan (the fan motor for the cooling circuit) has a limited lifespan. A fan motor with diminished
performance may lead to reduced cooling performance.
