4. Install the Rubber Fitting on the Vacuum
Pump. Hold the Rubber Fitting against the
Vacuum Pump so its wide opening faces the
funnel of the pump. Insert the funnel of the
pump into the Rubber Fitting and then push
the fitting against the funnel until it is fully
inserted (image #17).
5. Place the housing on a flat surface in a
shaded area and in a manner that enables
the housing to be left stable and
uninterrupted during the pre-dive check.
6. Connect the Vacuum Pump to the Vacuum
Valve by gently pushing the exposed valve all
the way into the Rubber Fitting of the pump.
7. Use the Vacuum Pump to pump air out of the
housing by gently and steadily pulling and
releasing its handle (image #18). While doing
so, carefully watch the LED Indicator through
the back door of the housing to monitor the
air pressure inside the housing as it progresses through the following stages:
a. Yellow flashing rapidly – air pressure has started to drop. Continue pumping.
b. Yellow flashing slowly – air pressure continues to drop.
Continue pumping. Note that that pumping should be
carried out at a slower pace as the Indicator LED flashes
slower and air pressure approaches the optimal level.
c. Steady yellow (no flashing) – air pressure has reached the
optimal level. Stop pumping and allow the analysis to begin.
d. Yellow & Red flashing alternately – indicates over pumping
and under pressure inside the housing. Stop pumping and
carefully release a bit of the vacuum by turning the Vacuum
Release Tip counterclockwise and pulling it out (image #19)
until the LED Indicator turns steady yellow, indicating a proper pressure for the check. If
the LED Indicator starts flashing yellow again, overpressure has been produced inside the
housing due to excessive vacuum release. Use the Vacuum Pump to extract air again until
the LED indicator turns steady yellow.
8. The analysis beings once the LED Indicator turns steady yellow. Carefully disconnect the Vacuum
Pump from the Vacuum Valve and reinstall the Protective Cap over the valve.
