13. Once the pre‐dive check is complete and the watertight seal of the housing has been confirmed:
a. Reinstall the Protective Cap over the Vacuum Valve if it hasn't been reinstalled yet. Note
that the Vacuum Valve is watertight even without the Protective Cap, as long as the
Vacuum Release Tip isn't pulled out during the dive. However, the Protective Cap ensures
the Vacuum Valve remains locked during the dive, so it's recommended to reinstall it
prior to diving with the housing.
b. Dive with the housing without detaching or attaching any accessories which their
installation might have an effect on the watertight seal of the housing.
Important Notice
14. After the dive:
a. Prior to opening the housing, make sure to completely release the vacuum by turning
the Vacuum Release Tip counterclockwise and pulling it out (image #40). This prevents
stressing the housing Latch Dial.
b. Turn the system off using the power switch on the Signal Board to save battery life.
Moisture Detector
The Moisture Detector allows monitoring the watertight seal of the housing during the dive. Moisture
detectors are very sensitive, so whenever moisture is detected by the sensor, the LED Indicator starts
flashing red and a warning alarm starts beeping, thereby alerting of a possible leak.
1. You can test the Moisture Detector (image #41) by
placing a wet finger over the moisture sensor
unit at the bottom of the housing.
2. In order to silence the alarm after it starts
beeping:
a. Gently wipe the Moisture Sensor unit with
a soft dry cloth in order to dry it off.
b. Switch the Vacuum System off using the
power switch on the Signal Board.
The Vacuum Safety System was designed to test and confirm the watertight seal
of the housing prior to the dive only.
Monitoring the watertight seal of the housing during the dive is carried out using
the Moisture Detector included in the system. See "Moisture Detector" section
below for further information.
