Alarm System
The built-in alarm has a 3-position switch. Set the switch to "test" to hear the alarm and light. Always make sure the alarm is working properly before installation. Once installed, set the switch to "alarm" (flashing light and alarm sound) or "mute" (flashing light but no alarm sound) depending on your preference.

Plain horizontal 18.0mm (0.71") O.D. outlet connection fits 3/4" I.D. tubing. A 3/4" rubber elbow is also included. Pump also comes with barbed fitting that threads into the interior of outlet to provide a 12.0mm (0.47") O.D. barb for 1/2" I.D. tubing.

2 Year Warranty
This warranty does not include the diaphragm kits, which are a replaceable, wearable part (typically replaced every 12-18 months). Warranties are at the discretion of the manufacturer as to whether the damage is due to misuse or to defect.

The most common problem with this and other larger air pumps is premature diaphragm tearing due to excessive back pressure. People don't tend to understand how much air the large sized pumps produce.    If an air pump is powering too small of a diffuser or too few outlets, excessive back-pressure can occur. The solution is to add a tee with a ball valve or other "bleeder valve" so that excessive air can be bled off into the atmosphere.    Start with the valve completely open and slowly close it until you have the maximum output from your air diffusers without unnecessary back pressure
