Daily maintenance and precautions for drug stability test chamber
1. When transporting equipment, the inclination angle should not exceed 45 degrees to avoid damage to the refrigeration system,
2. After the equipment is moved and placed in place, it should be left to stand for (1-2) days before starting up to facilitate the normal operation of the refrigeration system and extend its lifespan.
3. The device must be connected to a well grounded power outlet!
4. Equipment placement balance
After placing the equipment in place, add pure water to the water tank to the appropriate level, turn on the power switch of the equipment, and the water cup inside the tank will automatically add water. After about half an hour, open the box door and observe that the water level in the sink (humidification evaporator) on the bottom of the working room should be parallel to the bottom plate and submerge the evaporator, while not overflowing into the working room. If the requirements are not met, level the box foot or open the back plate, adjust the water level of the water cup to ensure that the humidification evaporator is completely submerged in water, so that the temperature inside the box is not directly heated during humidification.
5. When the temperature inside the box is below the dew point, the humidity probe is prone to water vapor accumulation after opening the box, causing the humidity to display 99.9%. At this time, the box must be heated and the humidity probe dried. It can only be used when the humidity display is below 99.8%.
6. When the equipment operates at low temperatures (below ambient temperature) for a long time, it must be defrosted at 40 ℃ for about 2 hours every half month before being put into operation;
7. When the equipment is not in use, it should be treated with moisture removal. The specific method is as follows: drain the water in the box, set the temperature at 40 ℃, run for 5 hours, and open the door every 2 hours to release the moisture. After treatment, unplug the power plug and store it.
8. The temperature requirement for the room where the equipment is stored is between 5-30 degrees Celsius. Any temperature higher or lower will accelerate the operation of the compressor and increase the load.
9. Keep the water in the storage tank clean to prevent it from becoming sticky after prolonged use. Regularly drain the water every 3-6 months. Disconnect the power supply of the submersible pump before draining water.
10. Remember to maintain the water level in the storage tank, which should not be lower than the water level at the interface of the submersible pump, to prevent dry burning and damage to the submersible pump.
11. The sink inside the equipment should be cleaned regularly every 6-12 months.
12. After completing high humidity, dehumidification should be carried out, and the temperature should be adjusted to 40 degrees Celsius with a humidity of 0. Run for 3 hours. Because humidity can affect electrical, conductive, and electronic components, the repeated opening interval of the compressor must be at least 5 minutes, otherwise it will damage the compressor.
14. The air inlet of the condenser fins will accumulate dust and form a cotton like texture after prolonged operation. When the device is running, use a high-power hair dryer for blowing,
15. Pay attention to the external cleanliness of the equipment and wipe it with a damp towel.
16. The maintenance of the drug stability test chamber should be carried out by qualified personnel, and our company's after-sales service center should be contacted before the maintenance.
