System Care & Maintenance
1.
You can use the Multi purpose key included periodically to make
sure the Vacuum Valve is tightly screwed into its port and was
not accidently loosened when unscrewing the Protective Cap
(image #21).
Do not over tighten the Vacuum Valve or this may damage the
port or the valve!
2.
The O-ring positioned between the Vacuum Valve and its
protective cap should be maintained periodically.
a.
Visually inspect the O-ring after removing the cap.
If there is any debris present, including dirt, sand, dust,
hair or any other matter, it must be cleaned to ensure a
proper watertight seal.
b.
In order to clean the O-ring, you can remove it from the Vacuum Valve.
c.
Cleaning the O-ring is a simple matter of wiping it with a damp, soft cloth to remove the
foreign matter. Be careful the cloth you use does not leave any of its own material
behind as this can also affect the effectiveness of the seal.
d.
Apply a slight layer of Fantasea Silicone Grease on the O-ring. Note that the amount of
lubrication required on the O-ring is only enough to allow it to slip into place without
friction, so it does not twist or become dislodged. More grease is not necessarily better,
and in some cases might interfere with the watertight seal of the housing.
e.
Reinstall the O-ring.
f.
Confirm that the housing watertight seal hasn’t been interfered using the vacuum pre-
dive check prior to diving with the housing again.
3.
Never soak or wash the interior of the housing with water. This will cause irreparable damage
to all Hybrid Vacuum Safety System electronic components!
