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. Remov e
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.

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 v ery 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 configur ation, r e-use t hes e Torx screws.

6. See Figure 4. Remove t he four screws
(arrowed) that hold the ap erture 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.

Figure 3

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.
