Safety Precautions

Optional Accessories

This recorder has been calibrated at the factory. It retains the temperature accuracy and calibration even when there is a power supply interruption. Should there be a need to recalibrate the recorder, please follow the procedures below.

a)Let the unit run continuously until it reaches a stable condition. The recorder has registered temperature for at least two hours.

b)Place a standard thermocouple in a 100 ml container filled with 10% glycerin solution. Place the container and the temperature recorder sensor in the unit. Do not place the recorder sensor in contact with any liquid.

c)After four hours of soak time at the stable freezer temperature, the container temperature should match the freezer temperature. Then compare the thermocouple reading with the temperature recorder reading. If there is a discrepancy, use the button (#1) or the button (#2) on the recorder to move the pen on the chart to reflect the correct temperature.

Note: The ink pen will operate 5 seconds after the button is released.

Caution: The temperature recorder is preset during production, so resetting of the temperature recorder is not recommended unless absolutely necessary.

NOTICE!

1.Freezer must be placed at least 200mm away from the wall to allow maximum air circulation.

2.Changing of the Refrigerants should be done according to the Service Manual.

NOTICE!

For the most efficient energy consumption and optimized compressor life,the temperature should be set at the highest temperature suitable for the samples to be stored,normally set at -50 to -80 .

When power to the unit is on, switch on the battery charger. When the unit	switch	battery Charge

is not in use switch power off and then switch off the battery charger..
