Checking The O-Ring - Fantasea Line FG7X II S Instruction Manual

CHECKING THE O-RING

1. Prior to each closure of the housing, the back door black O-ring should be visually inspected. 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.
2. In order to clean the black O-ring, first remove it from the housing:
a. Insert the O-ring remover between the black O-ring and the groove it is
seated in (image #7).
b. Slip the tip of the inserted O-ring remover below the black O-ring, while making sure the O-ring
doesn't get damaged (image #8).
c. Carefully hold the O-ring with your fingertips in order to remove it from the groove.
3. 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.
4. Apply a slight layer of silicone grease on the black O-ring. Please 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.
5. When replacing the O-ring, place it back into the groove starting at one corner and gently pressing it
into the groove all around the housing until it is all seated in the groove and no part of it is sticking
up or out of the groove.
