Step 3: Lock the retaining clip by pushing sideways while gently pushing forward.
Note:
The performance of saturated colors may be less than desirable in any theatrical
lighting fixture. For best results, always use high-quality color media rated for high-
temperature use.
ETC’s optional Conical Gel Extender, part # 7060A1048, will provide maximum
color media life. Gel Extenders are not recommended for 70° and 90° lens tubes
due to the extremely wide-angle beam.
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.

Replacing the HPL lamp
A lamp must be installed before you use the fixture.
Step 1: Disconnect power to the fixture before installing the lamp.
Step 2: Loosen the knurled bolt on the back of the lamp housing and pull the housing out.
Step 3: Holding by the base, remove the HPL lamp from its box.
Step 4: Align the flat sides of the lamp base with the retention brackets on either side of the
socket as shown in Figure 3.
Step 5: 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 he top edges of the retention brackets.
Step 6: Press lamp retaining clip across lamp base to secure.
Step 7: Reinstall the lamp housing by aligning the bolt hole and tightening the knurled bolt
Note:
Verify that the HPL lamp you intend to install is suitable for your facility’s voltage;
115-, 120-, 230-, and 240-volt HPL lamps are available.
See HPL lamp table, page 2. Operating HPL lamps above their rated voltage
reduces lamp life and can cause premature lamp failure.
WARNING:
Let the lamp cool before replacing.
CAUTION:
Use caution when installing or replacing any lamp.
When installing/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 cause premature lamp failure and socket problems.

Adjustments
Centering lamp and adjusting the field
The two concentric knobs located on the lamp housing allow you to align the lamp and adjust its
field. See Figure 4. The outer knob centers the lamp within the reflector. The inner knob adjusts the
lamp’s field.
Step 1: Turn on the fixture and aim it at a flat surface. Adjust the barrel to create a hard edge.
Step 2: Unlock and loosen the outer knob by turning it counterclockwise.
Step 3: Gently move the outer knob from side to side and up and down until the lamp is centered
within the reflector.
Step 4: Once the lamp is centered, turn the outer knob clockwise to lock it in place.
Step 5: Finally, turn the inner knob either clockwise or counterclockwise to achieve an optimum
flat field. See Figure 5.
Focusing the beam
On a fixed field angle Source Four jr., with a 26°, 36° or 50° lens, adjust the lens single beam focus
knob to focus the edge of the beam. On a Source Four jr Zoom, adjust the position of both lens
beam focus knobs to set the beam’s spread and to focus the edge of the beam. The Zoom lens
provide a range from 25° to 50°.
Step 1: Loosen the beam focus knob(s) on the underside of the barrel as shown in Figure 6.
Step 2: Slide the lens(es) forward or backward to achieve the desired beam edge.
Step 3: Once the fixture is focused, tighten the beam focus knob(s).

Shaping the beam
The beam can be shaped using the shutters (see Figure 1, a pattern or an optional drop-in iris.
Pattern Projection
The pattern holder slot is on the top side of the barrel and in front of the shutters. It accommodates
an M-size pattern holder (see Figure 7). The pattern holder handle can be bent away from the
shutter handle to keep it from interfering with the action of the shutter handle.
Use an optional donut in the accessory holder to enhance pattern projection. Donut diameter range
should be 2.5” to 2.75”.
Drop-In Iris Slot
The drop-in iris slot is located on the top of the barrel and in front of the pattern holder slot. It
accommodates either a drop-in iris or a motorized pattern device. When the slot is not in use, a
small sheet metal cover secured with two Phillips screws prevents light leakage (see Figure 8).
Step 1: Use a Phillips screwdriver to loosen the screws on the drop-in iris slot cover. Do not
remove screws.
Step 2: Slide the cover completely forward to expose the slot.
Step 3: Insert the iris with the flat side toward the shutters and make sure the iris handle extends
from the slot.
Step 4: Slide the slot cover back toward the shutters until it meets the iris handle. Leave enough
space to move the iris handle.
Step 5: Secure the drop-in iris slot cover by tightening the screws.

Adjusting the C-clamp
The C-clamp attaches the fixture to the mounting pipe and allows you to adjust the position of the
fixture once it is mounted (see Figure 9).
Step 1: Tightly fasten the C-clamp to the yoke with the provided yoke bolt and lock washer.
Step 2: Place the C-clamp on mounting pipe, then tighten the pipe bolt to secure it.
Step 3: Loosen the C-clamp pan screw and rotate the yoke to the desired position.
Step 4: Tighten the pan screw to lock the fixture.
Adjusting the yoke position
The Source Four jr / jr Zoom provide multi-positioning capabilities within its yoke for overall fixture
height and angle.
Setting the fixture height within the yoke
The fixture is equipped with a two-position yoke for modifying the overall height in which the fixture
is mounted (see Figure 10). To change the height position, perform the following steps.
Step 1: Remove the yoke locking knobs, washers, and hex bolts from either side of the fixture.
Step 2: Raise or lower the fixture to the desired position within the yoke.
Step 3: Reinstall the yoke’s hex bolts, washers, and locking knobs.
Step 4: Tighten the yoke knobs to secure in position.
CAUTION:
Tighten C-clamp pipe bolt to 15-20 ft./lbs. (approximately finger tight plus up to
one-quarter turn). Do not exceed 25 ft./lbs. Do not use excessive force.
Tighten the yoke pivot bolt to 5-10 ft./lbs. (approximately finger tight plus up to
one-eighth turn). Do not exceed 15 ft./lbs. Do not use excessive force.
