1. Preparation
All calibration assemblies must satisfy the maximum flow specification.
Prior to installation, thoroughly cleanse all ports and fittings to effectively prevent dust from entering the air passage.
Verify that the air flow direction aligns with the arrow markings on the product body and ensure the port and thread dimensions are properly matched.
2. Pressure Adjustment
Raise the pressure gauge knob and begin rotating it. A clockwise rotation will cause a steady and consistent increase in pressure, whereas a counterclockwise rotation will induce a pressure decrease.
Once the desired pressure value is attained, cease rotation and firmly depress the knob to secure it. Failing to perform this locking step may give rise to pressure leakage issues.
3. Dial Reading
Ensure the pressure gauge is securely mounted to the main assembly. During pressure adjustment, meticulously monitor the gauge to verify that the readings exhibit consistent and unobstructed fluctuations.
4. Drainage
The drainage column operates in a self-actuating manner, opening to discharge when there is no pressure and closing when airflow is present. In the event that the water level exceeds the upper threshold, immediate drainage is imperative; failure to do so will result in compromised dehumidification performance. The fitting on the drain head is designed for air hose connection and can be detached as per specific operational requirements.
5. Oil Adjustment
Rotate the needle valve clockwise (in the “+” direction) to augment the oil suction rate. Conversely, rotating the needle valve counterclockwise (in the “-” direction) will decelerate or halt the oil suction process.
6. Refueling
Rotate the fueling screw clockwise, ensuring the volume of oil added does not exceed 80% of the bowl's capacity. Upon completing the refueling process, securely tighten the fueling screw.
