Aqua Lung has announced a Safety Notice that affects YOKE versions of the Titan LX ACD, Core ACD, Legend ACD or Legend LX ACD regulators. Aqua Lung has identified that the ACD shutter valve in the first stages of these regulators with serial numbers starting with the letter E, F, G or H (prior to H043301) may not have been properly tightened during its initial assembly in manufacturing. Aqua Lung is concerned about a possible gas flow failure during a dive when the regulator has been fitted on certain cylinder valves
It should be noted though that if you have had your regulator serviced since purchasing it then this safety notice can be ignored as the component would have been corrected tightened during reassembly as part of the service. This also only affects the YOKE version of the first stages as the DIN versions use a different assembly.
These are the three first stages affected (found in four different regulator configurations)
How to Check Your Serial Number
If you think your regulator might be affected then your can check your serial number which is stamped into the side of the first stage and starts with a letter.
The affected range are those starting with the letter E,F,G or H (and prior H043301). If you have a Titan LX first stage you are only affected if the serial number starts with an E or F.
What To Do If You Are Affected
You should immediately stop using these regulators and take them to your nearest authorised Aqua Lung Dive Retailer or Dive Centre which can be found here. A certified technician will then be able to identify if your regulator is affected and take corrective action to bring it back in to full specification at no charge to you.
If you are local to our store then please bring your regulator in at your earliest convenience and we will carry out the necessary checks and corrections.
