8. OPERATION
SCUBAPRO S-Tek BC’s are supplied with the TEK BPI (K-Styled Inflator/Deflator Unit).
The TEK BPI, when connected to the tank and regulator by a Low Pressure hose,
makes it possible to control buoyancy in the water (inflation and deflation of the BC)
by using the inflate and deflate buttons.
Low Pressure (LP) Inflator hose (fig.13):
Locate the low pressure (LP) hose of the
TEK BPI Inflator/Deflator unit supplied
with your S-Tek 30,40 or 60 Wing.
Connect the LP hose to an unused LP
port of the first stage (fig 14). Note - LP
port uses a 3/8 UNF thread. Choose
the LP port that makes the most sense
for your personal configuration. This
should be torqued to 4 Newton Meters.
8.1 Connecting the TEK BPI (Inflator/Deflator Unit)
The TEK BPI allows you to inflate
your BC using gas from your SCUBA
cylinder. It’s LP hose, threaded on
an LP port of the firt stage regulator,
is connected to the TEK BPI by the
Quick Disconnect Coupling.
To attach the Quick Disconnect
Coupling:
1. Make sure that both fittings
are free of contamination prior
to connecting them together
(fig. 14-1).
2. Pull the collar of the Quick
Disconnect Coupling while
pushing the hose firmly onto
the fitting inlet on the S-TEK
inflator/deflator unit (fig. 14-2).
