80 mm lamp fan and lamp blower
The 80 mm lamp fan (526-0057-xx) and lamp blower (526-0056-xx) fasten to the side of the lamp
housing. The two fans work together to cool the lamp inside the lamp housing.
Both fans are included with a new lamp housing or with a new optical engine. Both are also available
separately.
To remove the 80mm fan
1 Remove the chassis and attached parts from the top case (see page 28).
2 Remove the optical engine (see page 47).
CAUTION Make sure you install the DMD protective cover before proceeding. (see page 48)
3 On the bottom of the lamp housing, remove the cable from the cable clip and pull the cable from
between the lamp housing and color wheel housing.
