Inner Frame Removal
To remove the inner frame, remove the
second stage regulator and then unscrew
(counterclockwise) the right cap with the
included OTS wrench. Once the cap is off,
stretch the skirt of the mask and lift the Inner
Frame in and out of the oral nasal pocket.
Acceptable 2nd Stage
Regulators
The regulator port of the Spectrum allows
regulators from 3/16” x 5/8” and sizes up to 1-7/16” x 13/16”.
NOTE : The regulator port can be safely stretched up
to 50% to allow bigger sized mouthpiece tubes.
Ensure the mouthpiece tube of regulator being installed has one single
lip that has a minimum length of .50” (See
Figure 12) and is not double lipped. DO
NOT USE REGULATORS THAT HAVE A
DOUBLE LIPPED MOUTHPIECE.
A properly secured mouthpiece and
regulator should be able to withstand a
weighted pull test of 25 pounds for 25
seconds.
NOTE : Not all second stage
regulators available can
be properly mounted.
