Preparation

The assembly of all calibrations shall meet the maximum flow requirement.

Please clean the port and fitting before installation, it will effectively avoid bringing dust to the air path.

Pay attention to the direction of airflow and arrow pointing on product body if correct, minding port and thread size if match.

Dial Reading

Make sure that the pressure gauge is tightly installed on the main body, and pay attention to whether the reading rises and falls smoothly while adjusting pressure.

Refueling

Rotates refueling screw clockwise, oil you add should not exceed 80% of the bowl. After refueling, please tighten the refueling screw.

Oil Adjustment

Rotate the needle valve in the “+” direction to increase the oil absorption speed, and it will slow down or stop when you rotate to the “-” direction.

Drainage

The drainage column will automatically excrete if there is no pressure, and it will close during the air flow passing. When the water level is beyond the upper limit, drainage is necessary, otherwise, that will cause poor dehumidification.

Pressure Adjustment

Pull up the knob of the pressure gauge, rotate:

If you do clockwise rotation, pressure will rise steadily. Pressure will down when you rotate counterclockwise.

Stop turning after reaching the required index and lock down the knob, forget this step you may face a leakage problem.
