6. If using a Delrin Isolation Kit, insert the Isolation Kit flat washer over the mounting tube and locate it flush with the
hull.
7. Insert the stainless-steel compression washer over the mounting tube.
The stainless-steel compression washer does not need to be flat to the hull, a slightly uneven surface can be
compensated by the washer.
8. Place the two C clips together to form a circle, ensuring you pair 1 threaded and 1 non-threaded hole together.
Fix the clips together using one of the screws provided so that the clips are located approximately halfway down
the length of the screw. Locate the clips into the appropriate grooves (depending on hull thickness) on outside
of the mounting tube so that the end of the screw is close to the washer. Fit the screws provided into the
remaining holes, fixing the two clips together. Leave the longer screw out to connect the light to the
vessel’s
cathodic protection system. Once connected, screw down this screw to the same position as the others (see
step 10)
9. Tighten the locking screws using a 5mm Allen key, applying thread lock at point of thread contact with locking
ring. Torque to 2Nm.
DO NOT
over-tighten locking screws, as you could damage the mounting tube, and this
will not be covered under warranty.
Once you are satisfied that the unit is fully tightened, you will notice that sealant has squeezed out from
around the perimeter of the light. Using a thinner or cleaner, apply to cloth and wipe off excess sealant to
leave a clean seal.
AVOID CONTACT WITH LENS
. If you do not see sealant squeeze out from the body, you
have not used enough sealant or tightened the unit enough to the hull. Carefully examine the installation to
make sure the sealant you have installed on the unit is fully watertight. If in doubt, remove light, re-apply
sealant and re-install.
10. Connect the bonding cable to the remaining screw and lock in place with the nut and shake proof washer
provided. Tighten the locking screw using a 5mm Allen key, applying thread lock at point of thread contact
with locking ring.
BONDING:
The light
MUST
be attached to the vessels bonding / cathodic protection system. Once fitted it
is mandatory to check that there is full continuity between the vessels cathodic protection system and the
outer bezel of the mounting tube assembly. Please see the bonding check schematic in the Appendix
(Section 7).
