REPLACEMENT OF WEAR-OUT PARTS
Replacing the battery for power failure alarm
Replace the battery for power failure alarm every 3 years (when F1 and chamber temperature is
displayed alternately) to ensure the alarm is operated in the event of power failure. Contact our sales
representative or agent for the replacement of battery when F-1 and chamber temperature is displayed
alternately.
The replacement of the battery for power failure alarm is a paid service.
The alarm function (blink of alarm indicator, sound of buzzer) will not operate when the battery for power failure
alarm is flat.
The alarm indicator blinks and the buzzer sounds by the battery for power failure alarm. The regular
replacement of the battery for power failure alarm is important to prevent the rise of chamber temperature in the
case of unexpected situation.
WARNING
The replacement of the battery for power failure alarm should be
executed by a qualified engineer or
service personnel only.
The replacement of the battery for power failure alarm involves the
risk of electric shock.
<Important> The used battery is a recyclable precious resource. Do not dispose of the battery.
Always follow the procedure for recycling.
Replacing the fan motor for cooling circuit
Replace the fan motor for cooling circuit every 6 years (when F2 and chamber temperature is displayed
alternately) to ensure the alarm is operated in the event of power failure. Contact our sales
representative or agent for the replacement of fan motor for cooling circuit when F2 and chamber
temperature is displayed alternately.
The replacement of the fan motor for cooling circuit is a paid service.
The appropriate operation of the unit is maintained by cooling the compressor with a fan. The motor to
operate the fan (fan motor for cooling circuit) is a wear-out part. A degraded fan motor for cooling circuit
may result in the poor cooling performance.
<Important> The alternate display of E10 and chamber temperature with buzzer sound means the
failure of fan motor for cooling circuit. In this case, contact our sales representative
or agent for the replacement of fan motor for cooling circuit immediately.
