This PVC register is used for outdoor air intake, indoor air exhaust, or indoor air outlet applications.

Usage Instructions

1. The outdoor air intake register should be installed near a window structure that prevents rainwater intrusion. A pest-proof mesh should be installed on the back of the outdoor air intake grille. The intake register operates quietly and allows precise airflow adjustment. (Refer to the operation section below.)
2. The indoor air exhaust register should be installed near a window structure that prevents rainwater intrusion. A pest-proof mesh should be installed on the back of the indoor air exhaust grille. The exhaust register operates quietly and allows precise airflow adjustment. (Refer to the operation section below.)
3. The indoor air outlet register is designed with an aesthetically pleasing appearance and ensures reliable air discharge without generating noise. The shutter on the back is solidly built, vibration-free, and allows precise airflow control.

Operation Functions

1. The front grille can be manually adjusted to freely change airflow direction up, down, left, or right. Use your fingers to set the desired direction.
2. The shutter can be opened and closed using a flathead screwdriver on the shutter control screw. Airflow adjustment is performed by referring to the indicator plate (○S⌒○O). Turn the screwdriver toward ○S to close and toward ○O to open. Use this method to adjust airflow as needed.
