4. With the nipple on the replacement lamp facing towards the back as shown in Figure 4, insert the left pin
into the socket. Push down on the right-hand spring and snap the pin into place.
5. Make sure that the terminals on the lamp sit below the V-section in the lampholder clips and not in the
V-section itself, as shown in Figure 5.
6. Lift the lamp assembly so that lamp is level with the center of the reflector. Push the assembly straight in
until it seats, making sure the lamp passes through the reflector opening.
7. Push and turn the 4 fasteners a quarter turn or so clockwise to close the lamp access panel.
8. After installing a new lamp, reset the lamp hour and lamp strike counters. See “Time” on page 14.
To align the lamp
Important! Align the lamp carefully. An excessive hot-spot will
damage optical components.
1. Apply power and allow the MAC 575 Krypton to reset.
Using either a controller or the control menu, strike the
lamp and project an open white beam on a flat surface.
2. See Figure 6. Center the hot spot vertically using the
top Allen-head adjustment screw (A) in the center of the
rear plate. Center the hot spot horizontally using the
side-to-side adjustment screws (C).
3. If there is an excessive hot spot, turn the bottom
adjustment screw (B) counterclockwise until the light is
evenly distributed. If the light is brighter around the
edge than it is in the center, or if light output is low, turn
the bottom adjustment screw (B) clockwise until the
light is bright and evenly distributed.
