Installation and Operating:

Preparation

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

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

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

Pressure Adjustment

Pull up the knob of 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 leakage problem.

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.

Drainage

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

Please be careful to use a wrench to tighten the fitting.

The first installation may have an excretion reaction(Not leakage, for the first time the internal pressure is different from the outside, it is necessary to discharge the excess air first). In this case, please wait for a while.
