o

Penholder
Install a recording pen in the recording hand as

completely inserted for accurate recording. The
pen is packed together with the chart.

the cartridge from the mounted position.
2. Insert a new pen.
3. Mount the cartridge into place.
4. Lift up the penholder lever and make sure that the
pen point touches the chart.
Note:
￭ Turn off the back-up switch when the freezer operation is stopped or the back-up system is not used.
The battery for back-up system is discharged when the back-up switch is kept on.
￭ The additional felt pen or recording paper is available from Sanyo sales agency.
￭ To stop the temperature recorder, remove the cell from the recorder. The back-up system can
operate without recorder cell. Always remove a felt pen as well because the recording paper can be torn
resulting from ink spot. The torn paper may interfere pen tip movement, which results in no activation of
back-up system.
￭ The cell for recorder normally keeps about 1 year. However, the cell life is shorten depending on the
ambient temperature condition. The enclosed cell may have shorter life since it is for monitor.
￭ The liquid leakage or rust can be caused when a used cell or a cell over effective limit is left as it is,
which gives adverse effect on the recorder.
