To be used with ETC Dimmer Doubler™

Color frame holder
The color frame holder is equipped with a spring-loaded retaining clip that prevents color frames and accessories from falling out.

WARNING : Make sure all color frame accessories are locked in position with the retaining clip before hanging the Source Four.

Release the retaining clip by pushing it sideways while gently pulling backward.
Insert the color frame.
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 number 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.
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 on 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 it.

Disconnect power to the fixture before installing the lamp.
Loosen the knurled bolt on the back of the lamp housing and pull the housing out.
Holding by the base, remove the HPL lamp from its box.
CAUTION : Use caution when installing or replacing any lamp. When installing/replacing a 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.
Align the flat sides of the lamp base with the retention brackets on either side of the socket as shown below. CAUTION : Improperly installed lamps cause premature lamp failure and socket problems.
Press the lamp retaining clip across the lamp base to secure it.
Reinstall the lamp housing by aligning the bolt hole and tightening the knurled bolt.

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 at right. The outer knob centers the lamp within the reflector. The inner knob adjusts the lamp’s field.

Turn on the fixture and aim it at a flat surface. Adjust the barrel to create a hard edge.
Unlock and loosen the outer knob by turning it counterclockwise.
Gently move the outer knob from side to side and up and down until the lamp is centered within the reflector.
Once the lamp is centered, turn the outer knob clockwise to lock it in place.
Finally, turn the inner knob either clockwise or counterclockwise to achieve an optimum flat field. See figure below.

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 provides a range from 25° to 50°.

Loosen the beam focus knob(s) on the underside of the barrel as shown at right.
Slide the lens(es) forward or backward to achieve the desired beam edge.
Once the fixture is focused, tighten the beam focus knob(s).

Shaping the beam

The beam can be shaped using the shutters, 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 at right). 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. The 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 below).

Use a Phillips screwdriver to loosen the screws on the drop-in iris slot cover. Do not remove screws.
Slide the cover completely forward to expose the slot.
Insert the iris with the flat side toward the shutters and make sure the iris handle extends from the slot.
Slide the slot cover back toward the shutters until it meets the iris handle. Leave enough space to move the iris handle.
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 at right).

Tightly fasten the C-clamp to the yoke with the provided yoke bolt and lock washer.
Place the C-clamp on the mounting pipe, and then tighten the pipe bolt to secure it.
Loosen the C-clamp pan screw and rotate the yoke to the desired position.
Tighten the pan screw to lock the fixture.

CAUTION : Tighten the 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.

Adjusting the yoke position
The Source Four jr/jr Zoom provides 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 below). To change the height position, perform the following steps.

Remove the yoke locking knobs, washers, and hex bolts from either side of the fixture.
Raise or lower the fixture to the desired position within the yoke.
Reinstall the yoke’s hex bolts, washers, and locking knobs.
Tighten the yoke knobs to secure in position.

Setting the angle within the yoke

Loosen the yoke locking knobs (see figure at right). Do not remove them.
Tilt the fixture to the desired position.
Tighten the yoke locking knobs to secure in position.

Lens and Reflector

Switching lens assemblies
Follow these procedures to replace a fixed field lens with a Zoom lens.

Loosen the screw at the front of the baffle. See figure at right.
Pull the light baffle out of the barrel.
Remove the beam focus knob from the bottom of the barrel and slide the lens assembly from the barrel.
Slide the Zoom lens rear assembly into the barrel and install its beam focus knob.
Slide the Zoom lens front assembly into the barrel and install its beam focus knob.
Reinstall the light baffle and secure it with the retaining screw.

Note : Reverse steps 1–6 to replace the Zoom lens with a standard lens.

Cleaning glass lens

WARNING : Do not use ammonia-based or other harsh commercial cleaners. Clean lens only as directed.
Commercially available glass cleaning agents should be avoided as 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.
