Thank you for choosing Leak Sentinel V5 XB, the premier pre-dive vacuum leak detection
system for underwater camera housings.
Please read this manual carefully before installing and using the Leak Sentinel V5 XB
1.
Safety precautions
Never dive or immerse the housing in any water without the protective cap. The rubber
valve is not watertight and serves only to hold the vacuum during the evacuating process.
Diving or immersing the housing without the protective cap will result in flood and/or
damage to your housing, camera and Leak Sentinel. Replace the protective cap
immediately after acheiving pre-dive testing vacuum.
Follow the standard pre-dive testing procedure immediately after installation to confirm
there is no leak. All units are tested thoroughly prior to shipping. In case your test shows
there is a leak, re-check the seal between the Leak Sentinel and the housing. It is the sole
responsibility of the user to ensure the tightness between the Leak Sentinel and the
housing. Vivid Housings will not be held responsible for any damage that may result from
the faulty installation and/or use of the product. If a problem persists, please do not use
the product and contact the manufacturer.
When screwing or unscrewing the protective cap and/or pump cap, always hold the valve
body with the opposite hand to ensure the housing body does not turn, loosening it from
the camera housing. A loose Leak Sentinel housing can cause a camera housing to leak.
It is not advisable to dive without a negative vacuum on the camera housing with the Leak
Sentinel installed. While diving with a negative vacuum on the housing should not result in
any damage, it is advised to always test the water-tightness of the housing and Leak
Sentinel prior to diving. After all, peace of mind, knowing the camera housing is secure, is
the reason for installing the Leak Sentinel in the first place. One should plan the dive so
there is time for pre-dive testing by performing the pre-dive procedures listed below in
Section 4. It may also be noted that many leaks occur in the rinse tank; this is because the
o-rings seal better under pressure and there is very little water pressure in a rinse tank.
