Ceiling and wall attachment
Dr. Mach
Lamps and Engineering
These mounting instructions must be kept together
with the lamp’s operating instructions for reference.
General instructions
All Dr. Mach lamps are supplied with a flange with
a graduated circle diameter 270mm and six bores
diameter 15mm. The flange supports the vertical
suspension tube. It is attached to the solid ceiling
by means of a ceiling anchorage ring.
Remark: The ceiling anchorage ring has to be
ordered separately!
The ceiling anchorage ring has six precisely posi-
tioned threaded bolts M12. It makes it possible to
fasten and adjust the lamp without causing dust or
dirt after all building work has been completed. The
use of a ceiling anchorage ring is necessary in all
cases of ceiling attachments.
During mounting, take care to ensure that neither
the flange nor the attachment elements are in con-
tact with reinforcement components of the solid
ceiling.
In view of the slight weight of the Dr. Mach lamps,
it is not fundamentally necessary to drill through
the ceiling and use a counter-plate. Ceiling an-
chorage rings can be attached without any prob-
lems to ceilings in the concrete strength class
greater than or equal to B25, using safety dowels
M8.
Depending on the stability of the location, it may be
necessary to use a counter-plate for the wall at-
tachment.
The forces arising when the widely extending ar-
ticulated arms tilt, do make it necessary to drill very
carefully with a certified hammer drill, paying close
attention to the drilling tolerances.
The suspension tube of the lamp or lamp combina-
tion must be adjusted vertically to prevent the lamp
body from moving. For this purpose the M12
counter nuts on the attaching bolts must be ad-
justed accordingly.
In case of false ceilings, the suspension tubes for
all lamps can be mounted directly through to the
solid ceiling. The opening required for this purpose
can be closed once the work has been completed,
using the canopy diameter 450mm or a covering
plate.
When using an intermediate flange (preferably for
spaces exceeding 400mm and for room heights
exceeding 4050mm), the length of the intermediate
flange is to be measured to the lower edge of the
false ceiling.
Also in this case a ceiling anchorage ring has to be
used for fixation.
