3.1 Unpacking, installation site, assembly
tools, safety information
Unpacking:
Please compare the delivery carefully with the
packing note, delivery note or invoice.
We strongly recommend that you keep a copy of
these documents with the manual, so that you
have information on the time and scope of the
delivery later when ordering more equipment or
when the microscope is serviced.
Make sure that no small parts are left in the
packing material.
Some of our packing material has symbols indicating environment-friendly recycling.
n.b.!
When lifting the microscope out of the packaging
do not touch any movable, mechanical components.
When putting the microscope on the desk and
adjusting its position, make sure not to damage
the sensitive damping feet on the underneath of
the microscope.
n.b.!
Do not connect microscope and peripherals
to mains yet (see section 3.2, Assembly)
Installation site
Make sure that the workplace is free from oil and
chemical fumes. Vibrations, direct sunlight and
major temperature fluctuations should be avoided. For ergonomic microscopy we recommend
a stable desk (about 70–80 cm high) and a comfortable, adjustable chair.

Safety information
This instrument of safety class 1 has been built
and tested according to EN 61 010-1/IEC 1010-1
safety standards for electrical measurement,
control and laboratory equipment.
n.b.:
To keep the microscope in this safe condition,
it is essential to note the advice and warnings
given in this manual.
The mains plug must only be inserted into a
grounded outlet.
If an extension cord is used, it must be grounded
as well. Any interruption of the ground connector
inside or outside the microscope or disconnecting the ground connector can render the microscope potentially dangerous. Intentional severance is forbidden!
n.b.:
Using the ground connection, any accessories connected to the microscope which have
their own and/or a different power supply can
be given the same ground conductor potential. Please consult our servicing personnel if
you intend to connect units without a ground
conductor.
Make sure that only fuses of the specified type
and rating are used as replacements. It is forbidden to use mended fuses or to short-circuit the
fuse holder.
n.b.:
The instruments and accessories described in
this manual have been safety-tested and
checked for possible hazards.
Before modifying the instrument in any way or
combining it with non-Leica products not
dealt with in this manual, it is essential to consult the Leica agency for your area or the main
factory in Wetzlar!
Any unauthorized alteration to the microscope or use for which it was not intended will
automatically terminate any warranty claim.
11
n.b.:
The electric accessories of the microscope
are not waterproof. If water gets inside them,
it may cause electrical shock.
Do not put the microscope and its accessories
near a water tap or anywhere else where
water may get inside them.
n.b.:
Before changing fuses or lamps, always turn
the mains switch off and disconnect the mains
cable.
n.b.:
Protect the microscope from major temperature fluctuations. These may lead to condensation which can damage the electric and
optical components.
n.b.:
Avoid skin contact when using immersion oil!
Ask the supplier for a safety information
sheet!

3.2 Assembling the lamp mount, mirror housing,
lamphousing, illumination telescope
1 Insert the lamp mount or the mirror housing in
the back panel and screw down with Allen
screws. Make sure the guide pin of the lamp
mount (7.1) engages in the back panel of the
microscope (6.2).
2 Put lamphousing 107/2, 107, 106Z onto the lamp
mount and screw down with the fixing screw
(9).
3 If you are using gas discharge lamps in
connection with fluorescence techniques we
recommend you use the illumination telescope
(8.4). This is inserted between the lamp mount
and the lamphousing 106Z and magnifies the
image of the focal point of the lamp by the fac-
tor 2x in the entrance pupil of the objective.
This results in substantially higher illumination
intensity for fluorescence.
3 Plug the lamp plug into the socket on the
microscope stand (6.3).
4 Insert a 50 mm light filter in each of the 2 filter
slots on the lamphousing mount (7.4)
4 Connect the mains cable to the mains socket in
the microscope stand.

3.3
Assembling and exchanging the incident
light lamps
Assembling and exchanging Hg and Xe lamps
Power units
Hg and Xe lamps are powered by separate power
units.
Please make sure to read the special manuals for
these power units.
n.b. It is extremely important to
heed the following advice!
Always disconnect the power unit from the
mains before assembling the lamphousing
106Z.
Wait for the lamphousing to cool down for at
least 15 minutes as otherwise it may explode.
Never touch glass parts of the burner with your
bare hands as finger perspiration burns in.
Wipe off any finger perspiration and dirt with
a clean cloth.
Adjust the lamps immediately after ignition
(see page 53).
Never look directly into the light path (risk of
glare)
Always wear the supplied gloves and face
mask when assembling Xe burners (risk of
explosion).
Type Average life span
Hg ultra high pressure lamp 50W (A.C.) 100 h
Xe high pressure lamp 75 W (D.C.) 400 h
Hg ultra high pressure lamp 100W (D.C.) 200 h
Hg ultra high pressure lamp 100W (D.C., type 103 W/2) 300 h
Avoid switching on and off frequently, as this
greatly reduces the life of the lamp.
Hot Hg lamps do not ignite again until they
have cooled down.
It is best to keep a record of the number of
hours a lamp has been in use (hour counter in
the power unit) and compare it with the manufacturer’s specifications.
Spent burners become discoloured and
should be exchanged before the specified life
expectancy has expired.
Ensure that lamphousing is adequately ventilated. Never block the air vents with paper, etc
(fire risk).
Dispose of spent burners in an environmentfriendly way.
Lamphousing 106Z L
Besides the halogen lamp, the following gas
discharge lamps can be used, which each require different lamp mounts (13) and power units:
n.b.!
1. the lettering is upright after insertion (different diameters of the metal base for the Hg 100
and Xe 75 burners ensure that these are
always inserted the right way up).
n.b.!
2. if the bulb has a seal point (13.2), the burner
is turned so that this point will be at the side,
not in the light path.
n.b.!
The Hg 50W lamp is correctly fitted when:
1. The type name stamp on the lower lamp
base is visible. It must be readable, i.e. not
upside down.
2. the upper base is labelled with the letters
- UP-.

Put the upper pin of the burner between the
clamps of the flexible power supply and clamp
with screw (13.1).
Unscrew the stud (13.3) in the holder slightly, insert the lower end of the metal base and retighten
the stud.
Make sure that the lamp base and the power unit
have the same number. If the lamp base is marked L1, for example, L1 must also be set on the
power unit to make full use of the lamp and not to
shorten its life.
Move the collector to the front position with the
focusing knob (14.1).
n.b.!
Remove the protective covering from the
burner (13.7).
Put the lamp holder with burner inserted into the
lamphousing and secure with the screws
(11.10).Try moving the collector (14.1): it must not
touch the power lead. When closing the lamphousing, make sure that the pins of the cut-out
plug engage in the sockets (11.11). Retighten the
screws of the lid. Push the cut-out plug in as far
as it will go.
Attach the lamphousing to the microscope and
connect to the power unit (compare mains voltage!)
n.b.!
Adjust the burner immediately after ignition.
To exchange the collector on the lamphousing
106Z:
Move the collector (11.2) to the rearmost position
with the focusing knob (14.1). Pull the focusing
knob of the collector outwards (the lamp is not
inserted) and remove the collector.

Assembly of Leica DMR tubes:
All the tubes in the Leica DMR range can be
adapted with the IR HC tube adapter (23.3):
e.g.
Binocular observation and photo tube HC FSA 25
PE (23.1)
Viewing angle 30°
With side port for reflecting measurement scales
and µ marks into the microscope image (slide
overlay) and for connecting the MACRODUAL
ZOOM device (see under Accessories, Slide
Overlay and Macro device)
Field of view index up to 22.
Eyepiece diameter 30mm for HL PLAN 10x/20 or
22 eyepieces
Eyepieces with larger field of view numbers are
not recommended for use on the DM IRM.
The tube adapter IR HC is mounted on the tube
change mount of the stand and stabilised by
tightening the clamp screw (23.4).
n.b.: Hold on to the tube adapter until the clamp
screw is tightened.
Then insert the HC FSA 25 PE tube in the change
mount of the tube adapter and fasten with clamp
screw (23.5).
The following tubes from the Leica DMR range
are also adaptable:
Bino HC BSA 25 (24.1)
Trino HC FSA 25 P and PR (24.2)
(P + PR = with and without back reflection)
Photo port for 1 photo/TV connection (25.2)
Photo port for 2 photo/TV connections (25.1)
Switchable 100%/100 % (25.3)
All Leica DMR trinocular tubes have the following
beamsplitting system:
100% vis., 100 % photo or 50%/50%.
