How to lift the light assembly out of the base or adapter
ring
Beside the simple jig delivered with the standard tool case, ADB has developed a
more sturdy and efficient lifting tool (see illustration below). See paragraph
Accessories, page 48 for references.
To lift the optical unit out of the base receptacle or adapter ring, proceed as
follows:
Step Action
1
Remove the fixing screws and washers (A1-A2) or self locking nuts and
discard them.
2
Fit the appropriate lifting tool into both holes located (180° apart) in the
cover (B1), lift the optical unit out of the base or adapter ring and place it
next to it.
3
Disconnect the light fixture wires from the power wires coming from the
transformer(s).
4
Remove the labyrinth gasket and discard it.
5
Mount a serviced or new fitting as described on page 17.
6
Take the optical unit back to the maintenance base where it can be
serviced entirely.
CAUTION: Never hold the light fixture by the wires as this may damage the
insulation, break the waterproof seal and cause insulation faults and water
leakage.
