4. LEAK TEST
4.1 Overview:
At this stage a gross leak test unit plunged into warm water is recommended.
Note: The leak test must be completed before the full function test.
Use hot water at 60°C ±5°C (140°F ± 9°F)
Cooler water will not raise the air pressure enough.
Hotter Water may damage the unit.
4.2 Instructions:
a) It is best to remove lanyard (if fitted).
b) Remove the Red cap and deploy the antenna (the unit will then turn on so
turn it off before proceeding)
c) Immerse the unit in the hot water.
d) Dislodge ALL trapped air from the screw holes etc.
e) During the next 5 minutes, rotate the unit and check for any escaping
bubbles
NB. If there is any sign of water ingress (bubbles are seen escaping), quickly
remove the unit from the water
f) If no bubbles are observed, remove unit from water and thoroughly dry
g) Refit removed parts.
Any escape of bubbles must be corrected by Disassembly, rebuild and re-test. A new sealing
kit will be required.
