5.5.2 Radiator Air Filter
NOTICE:
DO NOT try to clean and reuse old filters. The air filters in this product cannot be cleaned
thoroughly enough for reuse. Reusing air filters can lead to the contamination of optical components.
(Estimated Replacement Time: 2 minutes)
The radiator air filter is located on the left side of the
projector near the front. It is responsible for cleaning
the intake air before it goes through the radiator
(liquid to air heat exchanger) before moving into the
IOS compartment. It is recommended this filter be
replaced at the same time the light engine air filter is
replaced.
1. Push down on the snap tab at the top of the
cover. ( Figure 5-12 )
2. Pull cover out.
3. Slide the air filter out from the back of the cover
and discard.
4. When replacing, insert the new air filter with the
airflow indicator facing into the projector.
5.5.3 LAD Filter
(Estimated Replacement Time: 10 m 5 minutes calibration)
The LAD Filter is mounted together with the LAD fan in the light engine compartment. This assembly is
secured to the light engine handle. The LAD filter is responsible for filtering the already filtered air from the
light engine compartment, which is then directed to each DMD via clear tubing. The LAD filter rarely requires
replacement, but should be inspected regularly.
1. Remove the front top lid. See
5.4.2 Front
Top Lid, on page 5-5.
2. Remove the high security lid. See 5.4.3
High Security Lid, on page 5-6.
3. Pull the LAD filter out ( Figure 5-13 ).
4. Install a new LAD filter repeating the above
instructions in reverse.
5. Disconnect the three LAD hoses (one going
to each DMD) and turn projector power on
using the TPC. This allows any shavings
from the removal and replacement process
to be blown out of the LAD hoses, but not
onto the DMDs.
6. Re-connect the three LAD hoses again.
