CHECKING THE O-RING:
Prior to each closure of the housing the O-ring should be visually inspected. If there is any debris present,
including dirt, sand, dust, hair, grease or other matter, it must be cleaned to insure a proper watertight seal.
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. When replacing the O-ring, place it back into the groove starting at the same corner
and gently put it in by pressing it into the groove all around the housing until it is all sitting in the groove and
no part of it is sticking up or out of the groove. You can then apply a slight layer of silicone if you have not
done this yet. Be sure it is completely seated in the channel for a proper seal.
Lubrication of an O-ring does not improve the seal. It only reduces the
amount of friction on the O-ring when it is being moved into sealing
position. The amount of lubrication required on the O-ring is only enough
Note
to allow it to slip into place without friction, so it does not twist or become
dislodged. More grease is not better, and could in some cases have a
negative affect if it is applied in large amounts to form a build-up that
could trap any debris or foreign matter.
CLOSING THE HOUSING:
1. Place housing back over front and align the complete mating surface of the housing and the O-
ring, forming a proper seal.
2. Position all four latches over latch hooks in ready position.
3. Close all four latches at one time. If it is not possible to close all four latches at the same time,
close the bottom latches first, maintaining pressure on the other side. Then close the two top
latches simultaneously. Test all latches carefully to make sure that they are completely locked into
place and not just pushed down. Try to open them to make sure that they cannot open
accidentally.
