With this installation method, the light fixture is mounted onto the steel base, in
which the isolating transformer may be located.

For deep-base installation, contact Siemens Airfield Solutions Sales Department
and see the figure below.

To install the adapter ring, proceed as follow:

Clean the contact surfaces of the deep base and adapter ring.

Put onto the contact layer of the base a layer of RTV106 (Siemens
Airfield Solutions NC 7835.55.151 or equivalent.

Mount the adapter ring onto the base and torque down  the screws
supplied with it.  Refer to the table “Screws Overview” on page 44
for the tool to use, the torque to apply, and the eventual use of
“Loctite” sealing compound.

NOTE: When using an L-868B bottom section and top section, a minimum of 3-3/4-in.
height must be used for the top section or the fixture will not fit.  This dimension does not
account for flange rings and/or spacers.
NOTE: For fixture replacement on an existing L-868C 15-in. light base, L-850D/E inset
lights are supplied with 17.25-in.-diameter adapter rings.  For new fixture installation using
L-868B 12-in. light bases, L-850D/E are mounted directly to L-868B 12-in. light base without
adapter ring.
