Checking The Gasket - Fantasea FSB 800 Instruction Manual

CHECKING THE GASKET:

Prior to each closure of the flash housing, the gasket seal should be visually inspected. If there is
any debris present, including dirt, sand, dust, grease or other matter, it must be cleaned to insure a
proper watertight seal. Cleaning the gasket is a simple matter of wiping it with a damp, soft cloth
to remove any 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 gasket. It is not necessary to remove the
gasket for cleaning unless visual inspection determines that there is foreign matter underneath the
gasket as well. If this occurs, be sure the surface of the housing is also clean and wiped free of
any debris.
Since the gasket in the Fantasea FSB 800 Flash Housing is a face-to-
Gasket
face/compression seal, and is not subject to friction as it is closed,
Info:
there is no need to lubricate it. Grease or any other form of
lubrication does not help seal the housing. It only reduces friction,
which is commonly present if the housing has an O-ring seal.
Lubricating the gasket before use could cause it to slip out of its
groove, and not form a proper seal.
The gasket should also be checked visually for any cracks or
perforations. If any part of the gasket shows signs of wear or
damage, it is imperative that it be changed before going into the
water.
If the gasket is removed from the channel groove it sits in, be sure
to get it completely back into place so it is properly seated. Starting
at one corner, press the gasket with your finger and feel it seat into
its channel groove. Then continue this procedure continuously in
one direction, round its perimeter, until the entire gasket has been
pressed flat into place. Go over it a second time to be sure it is
properly in place. Then you are ready to clean it, give it a final
visual inspection, and close the housing.
