If the unit malfunctions, check out the following before calling for service. In the case of no refrigeration
or poor refrigeration, transfer the stored items to another refrigerator or freezer before checking out.
Malfunction Check/Remedy
When the buzzer sounds
continuously
In the event of lower limit temperature alarm
▪ The set temperature of the chamber is lower than the lower limit
temperature.
The lower limit temperature should be lower than the set
temperature by more than 5
o
C.
Set the lower limit temperature after actual temperature of chamber
reaches to the set temperature of operation.
In the event of upper limit temperature alarm
▪ The set temperature of the chamber is higher than the upper limit
temperature.
The upper limit temperature should be higher than the set
temperature by more than 5
o
C.
Set the upper limit temperature after actual temperature of chamber
reaches to the set temperature of operation.
▪ The excessive heat source is in the chamber.
Remove the excessive heat source.
For the allowable heat load, refer to the graphs on page 57.
When the program
operation does not function
well
The chamber temperature does not change according to the
program.
▪ The incubator performance (pull-up, pull-down) is not sufficient for
the program setting.
▪ The over-heat or over-cool alarm temperature is wrong.
These temperatures should be set 5
o
C higher and lower than the
upper and lower limits of the temperature controller respectively.
Once excessively high/low temperature limits have been
determined, the operation temperatures cannot be changed
significantly due to the existence of the limits for extremes of
temperature. For this reason, the excessively high/low
temperature limits should be set at a wide range when the program
operation is set.
Note:
If the malfunction is not eliminated after checking the above items, or the malfunction is not shown in the
above table, contact Sanyo sales representative or agent.

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.
