1. First, use a soft plastic pipe or rubber hose to lead out the outlet pipe of the drain pan for drainage. Place a 10 cm thick object on top of the germination box, then place the water spray tank on top, and use a soft plastic tube or hose to connect the water tank to the sprinkler nozzle duct.

2. Connect the "power plug" of the controller to 220 volts, 50 Hz AC, then connect the "control power plug" of the germination box to the "temperature control power output" socket of the controller, and then Set the temperature control knob of the controller at the required temperature, and the bean sprout machine can start working. Extremely simple and trouble-free.

3. In order to ensure the accuracy of the temperature control accuracy, after the bean sprout machine is installed or after a period of use, the temperature control accuracy can be calibrated as follows: Place the temperature probe and the standard thermometer close to each other. Together, place them on the upper level of the germination box. After controlling the heating of the germination box, start to calibrate the knob indication value on the thermostat, which refers to the accurate control temperature value at 1, 2, 3, 4, 5, etc. But after the knob is on "1", control the heating inside the germination box and observe the indicator light. When heating starts, the "heating indicator light" is on, but the "constant temperature indicator light" is off. After heating for a period of time, when the "heating indicator light" goes out and the "constant temperature indicator light" lights up, it means that the temperature in the germination box reaches the control temperature value. This is the value on the standard thermometer that is read out, that is, the knob It refers to the controlled constant temperature value at "1". After recording, continue to calibrate until all the actual control temperature values ??of gears 1-5 are calibrated.

4. Soak the seeds as usual and put them into the drain tray in the germination box (the drain tray should be kept as horizontal as possible when placing it), and then insert the temperature probe into the probe on the top of the germination box. On the rack, turn the temperature control knob to 25-27 degrees. Then the bean seeds begin to germinate. At this time, the automatic spray interval of the bean sprout machine can be adjusted to once every 2-3 hours. After the sprouts are 1 cm long, adjust the interval to spray once every 4-6 hours. The adjusted water temperature should be 3-5 degrees higher than the specified temperature, so that the temperature of the spray water is basically the same as the temperature of the bean sprouts at that time.
