Instructions:
1. Preparation
1 Connect the inlet and outlet ports of the equipment to the outlet and inlet of the experimental equipment with a heat-insulating hose. (Insulation hose is the accessory for the equipment)
2 Open the insulation cover and add water or other medium from the sink. The liquid must cover the evaporator.
â—† As shown on the right, the liquid should be added to the position shown.
3 turn on the power
â—† Make sure the safety switch is off before connecting the power supply.
â—† Plug the power connector into a dedicated outlet that has a reliable ground connection!
2. Operation
1 Turn on the leakage protection switch and the power switch.
2 set the required temperature
â—† I series control board description
1 . Click the “ SET †button, the upper limit temperature indicator on the left side of the display window will be on, and the temperature display window will display the upper limit set temperature.
2. Click the “ ▲ †button or the “ ▼ †button to increase or decrease the temperature until it is adjusted to the desired test temperature. At this time, the upper limit temperature is set, press the “ SET †button to save the settings . If you press the “SET†button for a long time to indicate the abandonment of the settings, the settings will be automatically exited and the original settings will be maintained.
* Press the “ ▲ †button or “ ▼ †button once to increase or decrease the temperature by 0.1 °C .
* Press and hold the “ ▲ †button or “ ▼ †button to keep the temperature from increasing or decreasing.
3 . Click the “ SET †button, the lower limit temperature indicator on the left side of the display window will be on, and the temperature display window will display the lower limit set temperature.
4 . Click the “ ▲ †button or “ ▼ †button to increase or decrease the temperature and adjust to the appropriate lower limit temperature.
*The lower limit temperature must be lower than the upper limit temperature by 3 to 6 °C .
5. After the lower limit temperature is set, double-click the “ SET †button to return to the actual temperature. Temperature at this time
After setting the Bi.
â—† II series control board description
1 . Press the “Power†button to display “...†for 4 seconds to enter the running state. The (PV) display window shows the value of the liquid temperature in the reservoir. The (SP) window displays the value as the current set temperature.
2 . After clicking the “SET†button, the (PV) window displays the SP word. At this time, press the up button “ ▲†or the down button “▼†to increase or decrease the temperature until the desired test temperature is adjusted. Then click the “SET†button again to save the settings and exit the settings. (Upward and down key click once to change 1 number, long press value will continue to jump)
3 turn on the cooling switch
â—†When the cooling switch is turned on, the compressor will start working after the delay time.
â—† In the I series control board model, when the temperature reaches the lower limit set temperature, the chiller stops working, and the temperature starts to rise. When the temperature reaches the upper limit set temperature and the down time reaches the delay time, the chiller works again.
â—† Press the cooling button in the II series control panel model, the cooling indicator light is on, the cold1 indicator flashes (in the delay), the high temperature machine starts after the delay is over, the low temperature machine starts and the cold2 indicator lights up after the internal set temperature After reaching the temperature set by the cryostat, the cryostat stops.
◆ When the temperature of the II series control board is lower than the set temperature by 2 °C, the chiller stops working, and the temperature starts to rise. When the temperature reaches 2 °C above the set value and the delay time reaches the delay time, the cooling The machine is working again.
4 turn on the cycle switch
â—†After the temperature reaches the set temperature, the circulation switch can be turned on to provide external coolant.
5 turn on the stirring switch
â—† In the test, if you need to stir, please put the magnetic stirrer to the bottom of the liquid storage tank or put the magnetic stirrer into the flask, then put the flask into the liquid storage tank (the distance between the bottom of the flask and the bottom of the liquid storage tank) It should be within 2 5 mm), then press the stirring switch, its corresponding indicator light is on, and the speed adjustment knob is adjusted clockwise to reach the user's required speed .
3. After use
1 Turn off the equipment to be cooled first, then turn off the circulating pump switch, stirring switch, refrigerator switch, power switch, zui, pull down the safety switch, and unplug the power plug.
2 If it is not used for a long time, please drain the coolant and rinse it off with water.
4 . Routine maintenance
To ensure good system plays zui cooling efficiency, in addition to ensuring the necessary clean air environment around the instrument, condenser surface must be regularly checked and any dust junction cleaning operations follow these steps:
1 Confirm that the device power plug is unplugged.
2 Remove the two screws under the air intake hood of the unit, then gently pull the cover off and remove it.
3 Use a soft brush or other similar tool to inspect and clean the dust on the mesh cover and condenser surface.
â—† Do not touch the condenser fins with your hands to avoid scratching your hands!
4 After cleaning, install the ventilation net cover and tighten the screws.
