Installation and Operation: 1. Clean the port and adjustment before installing, avoiding bringing dirty things to the air route. 2. Pay attention to the direction of air flow and the arrow pointing to the body if match, attention port and tooth type if correct. 3. Pressure adjustment: lift the pressure adjustment knob, clockwise rotation, pressure increases. Anti-blocking rotation, the pressure is low. Look at the air meter and the point range and adjust the required pressure, then press the button to the lock state. 4. Excretion from the water bowl. When there is no air pressure, the water bowl will be excreted automatically. When you have air pressure, the drain column will increase. excreted water bowl, releasing the drain column after finishing the drainage, then the drain column will be automatically recovered, the drain is over. When the water level is beyond the upper limit, please drain. Otherwise, that will cause poor dehumidification. Notice: Be careful to use a wrench to tighten the accessory. It is normal if there are additional threads, you may feel the last intervention to use. 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 excess air first. In this case, wait a while.
