Lamp Information 3
Installing and Replacing the Lamp
A lamp must be installed before you use the fixture.
Figure 2: Lamp door on bottom of the fixture
1: Disconnect power to the fixture before installing or replacing the lamp.
2: On the bottom of the fixture, turn the latch on the lamp door one quarter-turn and then open
the door.
3: Remove the lamp holder assembly by turning the knurled knob counterclockwise to release the
lamp socket assembly.
4: Twist the lamp socket assembly counterclockwise one quarter-turn and remove from the fixture.
Figure 3: Remove lamp with quarter-turn counterclockwise
Note:
Verify that the HPL lamp you intend to install is suitable for your facility’s voltage;
115V, 120V, 230V, and 240V HPL lamps are available. See HPL Lamp Table on
page 2. Operating HPL lamps above their rated voltage reduces lamp life and can
cause premature lamp failure.
WARNING: Unplug the fixture and allow it to cool down before changing the lamp.
CAUTION:
The socket assembly remains connected to the fixture by means of its
electrical leads. Do not pull the wired assembly or place undue stress on it.

5: If replacing a lamp, carefully remove the old lamp from the lamp socket assembly.
6: Holding the new HPL lamp by the base, remove it from its box.
7: Align the flat sides of the lamp base with the retention brackets on either side of the socket in
the lamp holder assembly as shown in
Figure 3 .
8: Push down on the lamp base until the lamp seats firmly. When properly installed, the top of the
lamp’s base will be even with the top edges of the retention brackets.
9: Reinstall the lamp holder assembly into its socket in the fixture so that the arrow points towards
the “unlock” icon on the socket.
10: Turn the lamp holder assembly clockwise one quarter-turn so that the arrow points to the “lock”
icon.
11: Turn the knurled knob clockwise to secure the lamp holder assembly.
12: Close the lamp housing door and turn the latch to secure the door.
CAUTION:
Use caution when installing or replacing any lamp.
When installing and replacing lamp, be sure to point the lamp away from
your face and away from others before inserting it firmly into the assembly.
This may prevent injuries if the lamp should break.
Note:
To avoid premature lamp failure, do not touch the lamp glass. If you do, clean it
carefully with isopropyl alcohol and a clean lint-free cloth. Allow to dry before
operation.
CAUTION:
Improperly installed lamps and lamp holder assemblies can cause premature
lamp failure and socket problems.

Using Accessories
The accessory holder is equipped with two slots and a locking door that prevents color frames and
accessories from falling out.
Figure 6: Accessory holder door in the open position
Figure 7: Fixture with accessories
WARNING: Make sure all color frames and accessories are locked in position with the
accessory door before hanging the fixture.
Accessories such as barn doors and color scrollers must be secured with safety
cables to the mounting position, such as batten, truss, or other secure
structure.
Fixture should never be oriented so that the weight of the accessories, such
as color scrollers or barn doors, rests against the accessory holder door.

The performance of saturated colors may be less than desirable in any theatrical
lighting fixture, especially when equipped with a 750W lamp. For best results, always
use high-quality color media rated for high-temperature use.
A variety of heat shield products is also available from many color media
manufacturers. Follow the manufacturer’s instructions for the use of these products.

Adjusting the Yoke
Adjusting the Yoke Balance Point
You can adjust the yoke mounting position on the fixture to accommodate varying weights of different

handle on the rear of the unit.
Figure 9: Yoke balance and angle adjustment

Installing the lens
1: Position the fixture with the front of the unit (lens side) facing you, and tilted slightly upward.
2: Hold the lens by the edge and position it so the stepped side faces the front of the fixture.
3: From the top of the fixture, slide the lens into the lens retaining slot and then rotate the top of
the lens into place.
4: Slide the plastic lens retaining clips on each side of the lens inward to secure the lens. See
Figure 10 .
Cleaning the Glass Lens and Reflector
Replace the lens if it contains visible damage such as cracks or deep scratches that may impair its
effectiveness.
The reflector is located behind the lamp. You must remove the lamp before cleaning the reflector.
Remove dust with a blast of oil-free air or wipe with a clean, lint-free cloth. You can use isopropyl
alcohol, distilled water, or a 50%–50% mixture of both to clean the lens and reflector.
Note:
Do not leave fingerprints on the lens. Handle the lens with a soft, clean cloth.
Note:
The lens will not fit properly and will not function correctly if it is installed with the
stepped side facing the rear of the fixture.
WARNING: Do not use ammonia-based or other harsh commercial cleaners. Clean lens
only as directed.
Commercially available glass cleaning agents should be avoided because they
may contain ammonia, other harsh chemical detergents, or abrasive agents.
These cleaners may damage the glass surface and the Anti-Reflective
coatings. Do not immerse or soak the glass in any cleaning solution.
