Temperature recorder

Ask a qualified technician or an after-sales maintainer to install the temperature recorder as follows:
1)

Remove the cover plate of temperature recorder.

2)

Install the temperature recorder in place and then fix it to the front panel with screws.

3)

Remove the screws of electric cabinet in the compressor compartment and then connect the
connecting wires of temperature recorder respectively to the freezer’s live wire and neutral
wire.

4)

Lead the sensor of temperature recorder in the freezer through internal sensor duct at the back
of compressor compartment. The sensor duct is from the sensor through-hole at the back of
freezer to the compressor compartment.

5)

Disassemble the holder of internal temperature sensor in the cabinet, fix the recorder’s sensor
and internal temperature sensor together, seal the sensor hole on the cabinet body and install
the cover in place.

6)

Bundle the connecting wires of recorder in the compressor compartment with cable clips.

7)

Fix and restore the cover of electric cabinet and the left panel of compressor compartment
respectively with screws.

Warning
Before installing the temperature recorder, be sure to switch off the power supply; otherwise
electric shock or fire hazard may occur.

In order to operate and use the recorder correctly, please operate as follows:
1)

You will see the recorder upon opening its door.

2)

Switch on the backup power supply, i.e. 9V DC battery in the upper left corner of recorder.

3)

Change a piece of new recording paper (see the figure below).

4)

Remove the plastic cap from the recording pen and close the recorder’s door.

Note: The recorder will not work until internal temperature reaches the recorder’s recording range.

When the freezer works, the recorder uses AC power supply in normal conditions. If AC power
supply goes wrong, the recorder’s LED indicator will flash to indicate abnormal power supply. And,
the recorder will go on recording internal temperature by using backup battery. Each backup battery
can support the recorder for about 30h (Note: In case of low battery charge level, replace the battery
in time to avoid corrosion of battery switch due to overdue replacement. To save battery charge,
please turn off the battery switch when the freezer is not in use. Please install a backup battery in
place to ensure normal recording in case of power failure during normal use). The recorder’s LED
indicator will continuously flash until main power supply (AC power supply) is switched on and the
backup battery is replaced. In case of low backup battery charge level, the recorder’s LED indicator
will flash to indicate the need of battery replacement.
