3. Select the manifold that matches the supply
pressure of the SCBA. The low pressure manifold
has a black handwheel, and is used with 2216/3000
PSI SCBA. The high pressure manifold has stainless
steel handwheels, and is used with 4500 PSI SCBA.
4. Connect the handwheel on the single end of the
manifold to the Posi3 USB through the high pressure
inlet fitting on the lower right front panel of the Posi3
USB. Make sure it is tight.
The correct manifold must be used to
ensure correct results during the bypass flow test.
If a pressure supply other than a cylinder is
used, make sure the supply regulator is set to the
appropriate pressure.
5. Connect the handwheel on the T-fitting to the air
source. Make sure that any valve used for the
pressure supply is located next to the T-fitting on the
manifold.
Make sure the manifold does not kink!
Kinking can cause the hose to rupture, which can lead to
serious injury, or death.
6. Connect the handwheel on the first stage of the
SCBA to the T-fitting on the manifold.

Attaching the First Stage Manifold
The first stage manifold is shown below and is
connected to the medium pressure fitting located on the
front panel.
An adapter is required to connect the first stage manifold
to the breathing apparatus. First stage manifold adapters
are specific to the SCBA and are only available from the
SCBA manufacturer.
Do not attempt to service SCBA without
the proper training from the SCBA's manufacturer.
Always follow the breathing apparatus
manufacturer's instructions when connecting the first
stage to the Posi3 USB.
Note: Detailed connection instructions for a variety of
models are available in the help files for the various
brand-specific Posi3 USB software versions.
7. You are now ready to start testing with the software.
Use the menu item Tests / Complete SCBA Test to
conduct a yearly flow test.
The Help file can be launched from the software at any
time by using the F1 key.
