TEMPERATURE RECORDER

Setting of back-up temperature

1.There is a red guide on the top of the temperature displayer. Adjust the guide with your finger to back-up temperature, at which temperature the auxiliary cooling system starts to operate.

2.Set at a temperature 15oC higher than that of the freezer compartment.

Penholder

Install a recording pen in the recording hand as shown in the figure. Make sure that the pen is completely inserted for accurate recording. The pen is packed together with the chart.

1. Let down the lever of the penholder, then pull out 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.
