Filter Replacement Whenever you replace the lamp – or more often if the projector is installed in an extremely
dusty environment – you should also replace the air filter. The filter is located on the lamp
side of the projection head, near the front (see Figure 2-1).
1. Turn off the projector. Allow the projector cooling fans to run for at least 10 minutes
prior to disconnecting the power cord and removing the lamp assembly for
replacement.
2. Disconnect the AC power cord from the projector.
3. Remove the screw holding the lamp/air filter cover in place. Then, lift the cover up and
away from the projector (see Figure 3-6).
4. Slide the old filter down and out, then discard.
5. Insert the new air filter, following the labeling for proper inside/outside orientation.
Slide all the way up, under top tabs.
6. Replace the lamp/air filter cover and tighten the screw to secure it.

Lens Replacement If you need to remove the lens – either to replace it or to prepare the projector for
shipment – see Figure 3-5 and proceed as follows:
1. Power down the projector and wait at least 10 minutes to allow the lamp to cool.
2. Remove the secondary anamorphic lens, if present.
3. Place the lens cap on the installed lens to protect it from damage.
4. Release the lens safety tether from the lens ring clamp (if installed).
5. Turn the lens locking lever to the “unlocked” (UP) position.
6. Pull the lens straight out.
If you are installing a new lens, refer to Installing the Primary Lens on page 24.
Always record the serial number of a new lamp. Do this only if you
have just installed a new lamp. This will ensure that the lamp timer
is not reset on an old lamp and that the number of hours logged on
the lamp is accurate.
Note
Use only Runco filters. Never operate the projector without the filter
installed.
