2nd Stage Regulator

See Safety note at bottom of this page:

	The Guardian full face mask has a custom designed 2nd stage regulator that was specifically designed for a full face mask. We also realized what is involved with the maintenance of a full face mask and regulator. We designed the 2nd stage with trouble free maintenance in mind - it is easily removed! This is important for cleaning and/or maintaining your full face mask. Locate the RED button inside the oral nasal cavity (Pictured on the left side).
	Depress the RED button (it is spring loaded).
	While the RED button is depressed, pull the 2nd stage away from the mask body. It will have some resistance due to the heavy duty O-ring seal. Notice on the top of the 2nd stage is an indexing plug. This is used to ensure the 2nd stage is reinstalled properly (see instruction manual before taking the system apart).
	After the 2nd stage is removed, the mask and/or 2nd stage can be cleaned or serviced. Service is to be performed by a *"Authorized OTS Service Technician"* only.
	The 2nd stage only has a few parts which makes it easy to maintain and is extremely cost effective. The few parts to the left are most of the parts found in the exhaust side of the 2nd stage.
	In a few seconds you can completely disassemble the 2nd stage. Only a few parts have to be replaced yearly (i.e. o-rings, sealing disc, etc.).
	The valve stem system holds the sealing cone.
	The sealing disc (blue in this picture) can be easily replaced ensuring your 2nd stage seals properly. You simply pull out the old blue sealing disc and push in the new one! This part should be replaced yearly or if it becomes damaged (only a certified OTS Authorized Technician should service the regulator).
	Part of the valve stem system is the sealing surface. The knife edge seals cleanly on the sealing disc.
	Reinstalling the 2nd stage is equally easy. Just line up the 2nd stage with indexing plug to the index on the full face mask body and snap into place.
	After the 2nd stage is snapped in place, give it a good tug to ensure it snapped in place firmly and you're ready to dive.

Safety Notice: Although the 2nd stage regulator is easy to maintain, the OTS 2nd stage must

only be serviced and/or disassembled by an OTS Authorized Service Technician. You can take

the 2nd stage off the mask body as per instructions found in the "Operators Manual" for storage

or cleaning only - NO SERVICING UNLESS TRAINED.

Cleaning Note: The United States Navy has recommended cleaning solutions and/or processes

to help kill germs in the mask/regulator. You can downloaded the report here
