output opening of the LED directly during installation or relamping.
Take the recessed luminaire out of the packaging and dismantle the individual
components.
The recessed opening is covered by the frame of the luminaire housing.
Fixing of the installation housing in the recessed opening is achieved by
using two adjustable springs.
Installation into inserted ceilings :

Recessed depth min. 95 mm.
Compress the fastening springs of the installation housing against their
spring pressure on both sides towards the housing and slide the installation
housing into the recessed opening.
The fastening springs catch the ceiling panel from the back side. Minimum
thickness of the ceiling panel is 5 mm. If minimum thickness of the panel is
less than 5 mm it must be reinforced from the reverse side. Maximum thickness
of the ceiling panel must be no mor than 25 mm.
Push the enclosed threaded rods through the two inside openings of the
installation housing and guide the clamping angle of the threaded rods
downwards onto the suspended ceiling.
Clip the threaded rods into their guide grooves and screw them in by hand as
far as possible.
Fix in end position with screwdriver (TX 10).
This clamp fixing prevents the installation housing from turning and dropping.
