I. Standardized Daily Operation

Standardized daily operation is the foundation for ensuring the equipment's service life. Specific requirements are as follows:

• Sample placement

Handle test samples with care to prevent containers from colliding with the chamber's inner walls and sensors (avoiding component damage). Arrange samples with a reasonable gap to ensure smooth air circulation inside the chamber, preventing overloaded operation of the cooling and heating systems due to poor local ventilation.

• Door operation

When opening or closing the chamber door, avoid excessive force to reduce impact between the door and the chamber body (preventing door gasket deformation). Close the door promptly after use to avoid a large amount of external air entering, reducing the workload of the temperature and humidity control systems.

• Parameter setting

Strictly follow the equipment operation manual to set operating parameters. Do not arbitrarily adjust temperature and humidity values beyond the equipment's calibrated range, preventing system components from malfunctioning due to long-term overloaded work.

II. Meticulous Regular Cleaning

Regular cleaning can avoid equipment damage caused by dirt accumulation, and the process should be carried out from the inside out:

• Inner cavity cleaning

Clean the chamber's inner cavity once a month. First, cut off the power supply and wait for the internal temperature to return to room temperature. Then, use a soft damp cloth dipped in neutral detergent to wipe gently, clean residual detergent with clean water, and finally dry with a dry cloth (avoiding detergent corrosion of the inner tank material).

• Detachable component cleaning

Remove detachable parts such as internal shelves and brackets, clean them separately, and reinstall them after drying.

• Exterior and ventilation part cleaning

Wipe the equipment's exterior with a dry cloth to remove dust and stains every week; use a small amount of neutral detergent for stubborn stains. Clean the heat dissipation ports and ventilation filters every two weeks: take out the filter, rinse it with clean water, and reinstall it after drying (preventing dust blockage from affecting heat dissipation and causing overheating damage to internal components).

III. Regular Inspection and Maintenance of Key Components

Core components directly affect the equipment's operating status and require regular inspection and maintenance:

• Refrigeration compressor

Check the compressor's operating sound and vibration once a quarter. If abnormal noise or vibration occurs, contact professional personnel for maintenance in a timely manner. At the same time, check whether the compressor's cooling fan operates normally to ensure good heat dissipation.

• Temperature and humidity sensors

Calibrate the sensors every six months. If the deviation exceeds the allowable range, replace or recalibrate them promptly (ensuring the accuracy of test data).

Pipeline connections: Regularly check the equipment's pipeline connections to see if there is refrigerant leakage, water pipe blockage, or water leakage. Handle problems promptly to avoid affecting the equipment's cooling and humidification functions.

• Door gaskets

Inspect door gaskets regularly. If they are aging, deformed, or poorly sealed, replace them promptly to prevent excessive fluctuations in internal temperature and humidity and reduce the equipment's operating load.

IV. Rational Control of Environmental Conditions

The equipment's placement environment has an important impact on its service life, and the following conditions should be met:

• Basic environment requirements

Place the equipment in a ventilated, dry area without direct sunlight. Maintain the ambient temperature between 5℃ and 35℃ and the relative humidity not exceeding 85%.

• Avoid adverse location factors

Do not place the equipment near heat sources or air conditioning outlets (preventing frequent start-stop of the equipment due to sudden ambient temperature changes and reducing component wear).

• Ground and dust control

Ensure the placement ground is flat to reduce vibration during equipment operation (preventing internal components from loosening or being damaged due to machine shaking). If the equipment is placed in a dusty environment, increase the cleaning frequency to prevent dust from entering the equipment and affecting the normal operation of circuits and mechanical components.
