20 MAC 250 Wash

Installing the wide-angle lens

A 61.5° cutoff-angle wide-angle lens is supplied with the MAC 250 Wash, together with all items necessary

to install it.

To install the wide-angle lens:

1. Disconnect the fixture from power and allow

it to cool.

2. Set the tilt lock and remove top and bottom

head covers.

3. See Figure 9. Prepare to hold the front lens

assembly as it is released, then remove the

four retaining screws and remove the

assembly.

4. See Figure 10. Place the front lens

assembly face down on a work surface.

Remove the 4 screws from the lens clamps,

then remove the clamps (A), the standard

lens (B) and the 4 silicone tubes (C) from the

lensholder ring (D).

5. Reassemble using the same screws but

replacing the standard clamps, silicone

tubes and lens with the extra items supplied

with the MAC 250 Wash.

Note that the smooth side of the lens must face towards the lamp, as shown in Figure 10. Make sure

that the lens is centered and sits flat on the lensholder ring (D). Tighten screws enough to compress the

silicone tubes and hold the lens firmly, as shown in Figure 11.

6. Reinstall the lens assembly in the head, reinstall the covers and release the tilt lock before applying

power.
