Seal Check
 Seal Check Manual. Follow the procedures in the Seal Check manual for verifying
integrity of the housing.
 Seal Check both Housing and external monitor. The external monitor also has a
Seal Check fitting. After drawing a vacuum on the camera housing, note the
vacuum level on the gage.
Next, move the Seal Check hose to the external monitor. Draw a vacuum close to
that of the camera housing. Remove and plug the Seal Check fitting on the external
monitor.
Move the Seal Check hose back to the camera housing and start the monitoring
process.
Why do this? The LCD cable is water blocked but not air-blocked. After drawing
vacuum on the external monitor air passes from there to the camera housing until
the vacuum is equalized. By drawing a vacuum on the external monitor, very little
air must pass between the housings
so the ‘settling’ process and determination of
housing integrity takes far less time.

CAUTION. ENSURE THE FITTING PLUG IS INSTALLED PRIOR TO SUBMERSION!
FAILURE TO DO SO WILL RESULT IN A FLOOD.
Final Checks

Visual Inspection. Look closely at all seal mates
– Port, Port Ring, Port base and
main housing seal
– for uneven gaps. Look over the housing one final time.

Verify operation. As a final check, power on the camera and verify all controls are
functioning normally. If you have the optional HD-SDI surface feed cable ensure an
image is present at the surface end.
