Alarm System
The built-in alarm features a convenient 3-position switch. To test the alarm and light, simply set the switch to "test." It's important to ensure the alarm is functioning correctly before installation. Once installed, you can set the switch to either "alarm" for both a flashing light and alarm sound, or "mute" for a flashing light without the alarm sound, according to your preference.

recommend using the provided rubber elbow when connecting 3/8" tubing for optimal performance. For larger tubing, you can connect it directly to the smooth outer surface of the air outlet. The 14mm outlet is suitable for 1/2" tubing, while the 18mm outlet can accommodate 5/8" or 3/4" tubing. If you intend to use 1/2" tubing with the 18mm outlet, you will need to purchase additional adapters.
