URGENT SAFETY NOTICE
OTS Guardian Regulator – Retaining Ring Test Procedure

The following are procedures to verify the 2nd stage regulator meets factory standards and is safe to dive. This test is due to some substandard parts that shrunk after about a month from the manufacturer. We have only found a few, however, safety is our number one concern, and it is worth sending out a safety notice to verify integrity of the GFFM.

Step 1 – As per our Operator’s Manual, remove the 2nd stage regulator from the mask body.
Step 2 – You will notice a “Parting Line”on the main 2nd stage housing body. We use this to line up the exhaust valve slot ports. You will be using this Parting Line to conduct the simple test.You will also notice that the 2nd stage housing has two accent rings. The mask we are testing is RED so the accent rings are RED. The ring will be based on the color of your mask. We will be using the upper large ring for the test.
Step 3 – Use a marker and place a mark at the Parting Line.
Step 4 – Grasp the marked ring firmly.
Rotate the entire assembly approximately 1/4 turn counterclockwise.
Step 5 – With moderate force, try to rotate the upper ring back (clockwise) past the Parting Line. The assembly should stop on or near the Parting Line. Technicians Note: we use approximately 45 inch/pounds of pressure when installing this assembly in the shop.If this assembly stops on or near the Parting Line, the 2nd stage passed the test and all parts are within factory specifications.
Example 1: If you rotate the assembly clockwise with moderate pressure and it jumps past the mark, your 2nd stage is not fit for diving and needs to be returned to the factory for repair. DO NOT DIVE THE SYSTEM.
Example 2: If you rotate the assembly clockwise with moderate pressure and it jumps out of the housing or you can pull the assembly out of the housing, your 2nd stage is not fit for diving and needs to be returned to the factory for repair. DO NOT DIVE THE SYSTEM.
