Retaining

clip

Source Four jr / jr Zoom

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:

1: Release the retaining clip by pushing it sideways while gently pulling

backwards.
2: Insert the color frame.
3: Lock the retaining clip by pushing sideways while gently pushing

forward.

Note:

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

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:

WARNING:

1: Disconnect power to the fixture before installing the lamp.
2: Loosen the knurled bolt on the back of the lamp housing and pull the

housing out.

3: Holding by the base, remove the HPL lamp from its box.

.

CAUTION:

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.

Let the lamp cool before replacing.

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.
