MAC 250™ Beam Kit
Installation Guide
Introduction
This Installation Guide explains how to install the MAC 250 Beam™ Upgrade Kit to convert a standard
Martin Professional™ MAC 250 Wash™ to a MAC 250 Beam model. Installation only takes a few
minutes. A fixture software update is required if the installed software version is earlier than v. 1.4.0.
If you keep the standard components you remove, the MAC 250 Beam components can be uninstalled
and the fixture returned to standard MAC 250 Wash configuration at any time.
The MAC 250 Beam Kit has part number P/N 91610101.
For the latest documentation and information about this and all Martin Professional products, please
visit the Martin website at www.martin.com.
Warning! The MAC 250 Beam has a much more intense light beam than the standard MAC 250
Wash. Do not use it to illuminate any surface closer than 3.5 m (11 ft. 6 ins.) from the front of the
head, or you may create a fire risk.
Make sure that the front lens does not face the sun directly for longer than a few seconds at any
time during daylight hours. The Beam lens can focus the sun's rays inside the fixture, causing
internal damage and creating a possible fire risk.
Apart from the new minimum distance to illuminated surfaces specified above, follow all the
other safety precautions in the MAC 250 Wash user manual when installing the MAC 250 Beam
Kit and using the modified product. The user manual is supplied with MAC 250 Wash fixtures,
and the latest revision of the user manual is also available for download from the Product
Support page for the MAC 250 Wash at www.martin.com
Disconnect the fixture from power and allow to cool for at least 20 minutes before starting work.
The MAC 250 Beam Kit must be installed by qualified professional technicians only. Read all of
this Installation Guide carefully before starting to install the Kit.
If you have any questions about how to install the MAC 250 Beam Kit or use the MAC 250 Beam
safely, please contact your local Martin distributor (see www.martin.com/distributors for details)
or call the Martin 24-hour service hotline on +45 8740 0000, or in the USA on 1-888-tech-180.
Important! Do not get oil or grease onto optical components. If necessary, clean components
with 99.9% isopropyl alcohol.

Tools required
Screw sizes given in this Installation Guide are indicative only.
The following tools are normally required to install the standard MAC 250 Beam Kit. However, if screws
have been replaced during service, for example, you may find that other tools are required.
• Pozidriv PZ1 and PZ2 screwdrivers
• Torx TX20 screwdriver
Installation procedure
To install the MAC 250 Beam components in a standard MAC 250
Beam fixture:
1. Disconnect the fixture from power and allow it to cool.
2. See Figure 1. Release the head cover retaining screws
(arrowed) and remove both head covers. You can either let the
head covers hang on their safety cables or unclip their safety
cables and remove them completely, whichever is more
convenient.
3. Apply the tilt lock with the head topside up (in this position the
text on the back of the head is the right way up).
4. See Figure 2. Remove
the four crosshead
retaining screws from
the front lens
assembly and remove
the front lens. The
screws have Loctite
applied at the factory,
so take care when
removing them. Store
the front lens for
possible re-use if the
fixture is to be
returned to standard
MAC 250 Wash
configuration at a later
time. You can send the
screws for scrap metal
recycling, because
new Torx screws are
supplied in the Kit.
Figure 1
Figure 2
MAC 250 Beam Installation Note 3
5. See Figure 3. Fasten the new front lens
mounting bracket (P/N 62420240) supplied in
the Kit to the front of the head using the four
M4 X 12 Torx 20 screws (P/N 08070710) also
supplied in the Kit. Apply a very small quantity
of Loctite to the threads before tightening the
screws.
If you reinstall the original front lens at a later
date to return the fixture to standard MAC 250
Wash configuration, re-use these Torx screws.
6. See Figure 4. Remove the four screws
(arrowed) that hold the aperture plate in place inside the front
of the head. See Figure 5. Remove the aperture plate and
install the new aperture plate with shield plate (P/N
23819530) supplied in the Kit in its place, re-using the
original four screws. The shield plate in the aperture plate
must face upwards as illustrated to protect the wiring in the
head from sunlight that might be focussed into the head by
the new front lens assembly.
If you reinstall the original front lens at a later date to return
the fixture to standard MAC 250 Wash configuration, you
must remove the new aperture plate together with the new
front lens assembly.

7. A set of six beam effect gobos (P/N 62420250) is supplied in the Kit. See Figure 6. To install a beam
effect gobo, remove a color filter from the color wheel by pressing it gently away from its retaining
tabs (A) and lifting it carefully out of the color wheel (B).
8. Filters and gobos have small beads of silicone applied to them to act as cushions. If a bead of
silicone from a color filter has become stuck to the color wheel, remove it and replace it on the color
filter.
9. Insert gobos with the silicone beads facing the color wheel with reference to Figure 7 and to the
illustration on the last page of this guide. Store the original color filters safely for possible future
re-use.
10. We recommend that you install beam effect gobos in the
color/gobo wheel in the positions seen from the front lens
side* shown in Figure 7 in all the fixtures you modify, so that
all MAC 250 Beam fixtures will have identical behavior under
DMX control. A larger copy of this illustration is included on
page 6 of this guide.
*The previous revision of this installation note showed the
color/gobo wheel seen from the lamp side. Figure 7 shows
the wheel seen from the front lens side instead to give a true
picture of the wheel in reality, because the front lens side is
where the color filters/gobos are actually installed. Note that
when viewed from the front lens side, the gobo slots are
numbered counterclockwise.
11. See Figure 8. The new
front lens assembly (P/N
62409076) has a safety
cable with a carabiner
clip. Attach the clip to the
head using either of the
two holes (A) provided in
the new front lens
mounting bracket, then
push the clip flat (B) to
give space for the front
lens assembly.

12. See Figure 9. Clip the new
front lens assembly securely
onto its mounting bracket in
the front of the head.
13. Stick the warning
label supplied in
the Kit onto the
back of the head as
shown in Figure 10.
With the Beam Kit
installed, this label
replaces the
warning printed on
the standard MAC
250 Wash. Do not
illuminate any
surface within
3.5 m (11 ft. 6 ins.)
of the MAC 250
Beam. Do not
allow the front
lens to point at
the sun.
14. Finally, before using the fixture, update the fixture software to version 1.4.0 or later, following the
software update instructions in the MAC 250 Wash user manual. From software v.1.4.0, the frost
filter is moved very slightly forward in order to reduce reflections from the CMY flags. There is no
need to roll back the software to an earlier version than v.1.4.0 if the fixture is returned to a standard
MAC 250 Wash configuration at a future time.
The front lens assembly must be unclipped and removed from the head when the fixture is packed in a
MAC 250 flightcase. We recommend that you re-use the assembly’s protective packaging supplied in
the MAC 250 Beam Kit and store the assembly in the tray in the flightcase.

To give a realistic picture of the color/gobo wheel, this illustration shows the wheel as seen from the front lens
side – the side where color filters and gobos are actually installed. The previous revision of this installation note
showed the color/gobo wheel as seen from the lamp side.
Note that when the wheel is viewed from the front lens side, the gobo slots are numbered counterclockwise.
