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 positioned 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 contact 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 anchorage rings can be attached without any problems 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 attachment.
Dr. Mach
Lamps and Engineering
The forces arising when the widely extending articulated 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 combination must be adjusted vertically to prevent the lamp
body from moving. For this purpose the M12
counter nuts on the attaching bolts must be adjusted 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.

Static inspection
Note:
The static (structural) inspection must be carried out before the installation of the
ceiling or wall anchorage!
- The strength of the construction must be designed, checked and certified by a structural
engineer.
- The respective regional construction regulations that apply must be followed.
- If a wrong hole is drilled by mistake, e.g. drilling of a reinforcement rod, the structural engi-
neer who is responsible must be contacted, since adequate static load distribution in the ceiling may have been endangered.
Declaration of acceptance:
It is hereby certified that the supporting ceiling / wall and the ceiling anchoring / wall anchoring
is safe and adequately strong.

2. Ceiling attachment
2.1 Preparatory work on the ceiling
2.1.1 Setting the safety dowels
Attention:
Lamps, ceiling anchorage rings and intermediate flanges may only be attached to a ceiling of
concrete strength class greater than or equal to B25. In case of light-weight ceiling coverings,
the dowel anchor must be sunk completely into the concrete. To bridge this space use long
threaded bolts for attaching the ceiling tube.
In addition, take care that neither suspension tube nor attaching elements come into contact
with reinforcement components of the solid ceiling.
The lamp weight and the tilt of the long articulated arm(s) require that this work is performed
meticulously. This refers particularly to the use of a certified hammer drill and to observe the
drilling tolerances.
2.1.2 Mounting the ceiling anchorage ring to the solid ceiling
The scope of supply includes:
1 attachment set, consisting of:
• Six safety dowels Fischer FHA 12/50 galZn
• Mounting data Fischer
• Bore template
To attach the ceiling anchorage ring to a solid ceiling proceed as follows:
• Drill the bore holes according to the figure diameter 12mm and at least 100mm deep with a
certified hammer drill, using the enclosed bore
template. You can also use the ceiling anchorage ring as a template. In this case a second
person may be needed to assist.
• Insert the safety dowels through the bores of
the ceiling anchorage ring in such a way, that
the washers lie flat to the ring.
• Tighten the screws carefully using a torque
wrench (25Nm).
Light-weight ceiling panelling with a maximum
thickness of 30mm can be bridged using the enclosed safety dowels. For panelling thicker than
30mm, it is necessary to remove the panelling before mounting.

2.2 Pre-assembly of the ceiling flange and suspension tube
and installing the electrical connections
The length of the suspension tube is adjusted to the required room height with a clearance height of at
least 200cm under the lamp.
2.2.1 Aluminium cast flange and suspension tube ∅ 50mm
For the double models, slide the canopy (if not divided) and the ring over the corresponding suspension
tube before mounting the ceiling bearing. This step is not necessary for the single models as the canopy
can be slid into place after mounting the suspension to the ceiling.

Standard version
The diagram shows the single model and applies in
the same way to the double and triple models.
• Cable or cord showing out the suspension tube
is to be pushed carefully into the ceiling flange
together with the suspension tube.
• Push the suspension tube upwards until the
safety pin 1 can be pushed through the cross
bores of the suspension tube.
• Then pull the suspension tube down until the
safety pin 1 lies in recess A of the ceiling
flange.
• Then secure the connection with six screws 2
and washers 3 to prevent wobbling. If not possible, turn suspension tube by 180°.
• Pull the cable or cord through the bore 4 as
shown in the diagram.
Note:
The suspension tube is delivered with premounted retaining ring for the ceiling canopy.
Each connection journal is also equipped
with:
• 2 spacer rings
• 1 gib ring
• 1 circlip (Seegerring)

2.2.2 Flange tube ∅ 70mm
When necessary (in case of very high rooms or heavy lightning systems) a welded construction is used in
which the ceiling flange is welded to a tube. Also for double and triple types, slide the canopy (if not divided) and the ring over the flange tube before mounting the suspension tube.
Standard version
The diagram shows the triple model and applies in
the same way to the single and double models.
• Cable or cord showing out the suspension tube
is to be pushed carefully into the ceiling flange
together with the suspension tube.
• Push the suspension tube down until the safety
bolt 1 can be pushed through bore B of the
flange pipe into the cross bores of the suspension tube.
• Then pull the suspension tube down until the
safety bolt lies in recess A of the ceiling flange.
• Then secure the connection with six countersunk screws M6x16 2 (tool: hexagonal socket
wrench) to prevent wobbling. If not possible,
turn suspension tube by 180°.
• Pull the cable or cord through the bore 4 as
shown in the diagram.
• Fix the covers 5 on screws 2.
• Put the two covers on the bores B.
The table on page 9 shows the recommended distance between floor and suspension tube.
Please check this distance when mounting the
lamp.
Note:
The suspension tube is delivered with premounted retaining ring for the ceiling canopy.
Each connection journal is also equipped
with:
• 2 spacer rings
• 1 gib ring
• 1 circlip (Seegerring)

2.3 Mounting the flange and the suspension tube to the ceiling
Before mounting the flange and the suspension tube, assembly work on the ceiling (setting the dowels or
mounting the ceiling anchorage ring and possibly mounting the intermediate flange) must be completed
and all pre-assembly work finished.
Type with ceiling anchorage ring
• Screw three nuts B (each 120°) to the plate of
the ceiling anchorage ring, holding the other
three nuts 0,5cm away from the plate, unscrew
nuts A.
• Position six washers C and six insulating wash-
ers D on the flange.
• Position the flange with suspension tube on the
threaded bolts and adjust it to the required
height using three nuts A and washers C, insulating washers D, and retaining washers E
(each 120°).
Note: Washers C, insulating washers D and
retaining washers E must be put on the
flange in the same order as shown in the
figure.
• The three-point mounting allows a simple vertical adjustment of the suspension tube.
Vertical adjustment is very important and
must be carried out with great care.
If the flange with suspension tube is not in the correct vertical setting, the support arms of the lamp do
not remain precisely in the proper position, they
could turn away and would therefore require excessive braking.
• Then position from above all six nuts B gently
against the flange.
• Screw on the remaining three nuts A with
washers C, insulating washers D and retaining
washers E and tighten all six nuts equally
cross-wise with a torque wrench (25 Nm).
Note: Washers C, insulating washers D and
retaining washers E must be put on the
flange in the same order as shown in the
figure.
• Verify balance with a spirit-level.

Type with ceiling anchorage ring and
intermediate flange
• Screw three nuts G (each 120°) to the plate of
the ceiling anchorage ring, the other three 1cm
away from the plate, unscrew nuts F.
• Position the intermediate flange on the
threaded bolts and adjust it to the required
height using three nuts F and washers H.
• Then position all six nuts G gently against the
intermediate flange from above.
• Screw on the remaining three nuts F with
washers H and tighten all six nuts equally
cross-wise with a torque wrench (25 Nm).
• Verify balance with a spirit-level.
For mounting the flange to the intermediate
flange proceed as described at the design with
ceiling anchorage ring.
