1. Open the package and place it smoothly. Remove the foam and base for fixing inside and outside the box. The cold box after moving should be allowed to stand for 2 hours before use.
2. Turn on the power (220V AC mains) through a 10A knife switch or air switch, open the power switch on the louver below the right side of the device, the front right lower temperature controller digital meter, display the time box Internal temperature.
3, microcomputer digital display temperature controller, temperature adjustment control settings as follows:
1. Heating and heating
1 First, turn the selector switch on the louver below the right side to the high temperature position, press the â–² or â–¼ button of the temperature controller for three seconds to display the set value temperature, press â–² or â–¼ to display the display Constant temperature value is required.
2 Press SET 毽 multiple times or wait 10 seconds to return to the current temperature in the display box. At this time, the red light and the green light are on, and the heating temperature is started. When the set temperature is reached, the green light stops and stops heating. When the temperature inside the box drops below the preset set temperature, the heater automatically starts heating up again. When the preset temperature is reached, the green light is off.
3 When the green light is off, the light is turned on and off, so that the temperature inside the box is automatically kept at a constant temperature between 1.0 degrees above and below the set value.
2. Cooling and cooling 1 First, turn the selector switch on the louver below the right side to the low temperature position. Press the SET button of the temperature controller for three seconds to display the temperature of AL and the set value alternately displayed. Press â–² or â–¼. Make the display to the desired constant temperature value.
2 Press SET 毽 multiple times or wait for 10 seconds to return to the current temperature in the display box. At this time, the green light will be off when the green light is on, the red light will be on, and the cooling will start to cool down. When the set temperature is reached, the red light will stop and cool down. When the temperature inside the box rises above the preset set temperature, the red light of the temperature controller lights up, and the refrigeration compressor starts working again to cool down and automatically maintains the constant temperature. When the red light is off at constant temperature, the temperature in the box is between 1.0 degrees above and below the set value.
3. After 6 hours of work, check that the preset temperature is correct, then put the tested items and cover the top cover.
After a certain period of time, it takes about 1 hour to drop from +20 °C to -30 °C when no load is placed, and 0.5 hour from +20 °C to +85 °C. When the temperature reaches the preset temperature, it automatically stops cooling or heats up. And is in a state of heat preservation. When the temperature inside the box rises above the preset temperature or decreases below the preset temperature, the cooling or cooling is automatically started. The cycle is automatically maintained at a constant temperature.
