Removing a lens

Change lenses if they become cracked or badly scratched.

1.

CE Source FourPAR lenses get hot while the unit is on. Let the
luminaire cool before handling the lens.

2.

Place the luminaire on a flat, stable work surface. Do not install or
remove lenses with the unit hanging in the air.

3.

Remove the safety screen by squeezing the screen clip with your
thumb and forefinger. Pull the screen out (

Figure 2

).

4.

Position the lens rotation ring with the spring clip located at the top
of the unit, directly below the retaining clip (

Figure 3

).

5.

Tilt the front of the luminaire down at least 45 degrees.

6.

Press the spring clip with your finger to release the lens (

Figure 2

).

7.

Allow the lens to drop forward from under the clip.

8.

When the lens drops, remove your finger, allowing the lens to slide
forward until it rests on the lens catchers (

Figure 4

).

9.

Carefully remove the lens from the luminaire.

Installing a lens

1.

Position the luminaire with the front of the unit (the lens side) fac-
ing you and tilted slightly (

Figure 5

).

2.

Position the lens rotation ring with the spring clip located at the top
of the luminaire, directly below the retaining clip.

3.

Hold the lens by the edge, and position it so the convex side faces
the back of the luminaire (

Figure 5

).

Note:

Installing the lens with the convex side out will not impair
the optics, BUT it will make lens removal difficult and reduce
gel life.

4.

From the top of the luminaire, slide the lens behind the lens
catchers and position its base behind the tabs on the bottom of the
lens rotation ring.

5.

Gently push the top of the lens inward until it snaps behind the
spring clip

.

6.

Install the safety screen before using. To install the safety screen,
squeeze the screen clip with your thumb and forefinger and place
the safety screen in the lens rotation ring. The screen clip must be
placed below the retaining clip (

Figure 2

).

WARNING!

Unplug the luminaire before attempting to remove or

install a lens.
