1
00:00:00,533 --> 00:00:03,503
To hang a lighting instrument on a pipe,
first place the instrument’s

2
00:00:03,503 --> 00:00:09,442
C-clamp on the pipe with the bolt
pointing away from the area of focus.

3
00:00:09,542 --> 00:00:12,545
This will allow you to have complete
control of the unit when focusing

4
00:00:12,779 --> 00:00:15,949
without having to over-extend your reach.

5
00:00:16,049 --> 00:00:18,351
Once the instrument is placed properly,

6
00:00:18,351 --> 00:00:21,388
hand-tighten the C-clamp.

7
00:00:21,388 --> 00:00:27,260
Using a “C” or “open end adjustable”
wrench, tighten the bolt

8
00:00:27,260 --> 00:00:32,465
by either two quarter-turns
or one half-turn clockwise.

9
00:00:32,532 --> 00:00:34,467
Remember the direction with the rhyme

10
00:00:34,467 --> 00:00:38,338
“Righty tighty, lefty loosey”. 

11
00:00:38,338 --> 00:00:42,642
Once the C-clamp is securely tightened, attach
a safety cable to the unit and pipe.

12
00:00:42,709 --> 00:00:51,317
This will ensure that the instrument
will not accidentally fall.

13
00:00:51,418 --> 00:00:53,219
Do not leave the unit
hanging straight down.

14
00:00:53,219 --> 00:00:55,922
Raise the front of the unit up slightly.

15
00:00:55,922 --> 00:00:58,825
This will ensure the gel will not fall out
when the pipe is flown out

16
00:00:58,825 --> 00:01:06,132
to trim height.
If hanging a leko,
pull the shutters all the way out.

17
00:01:06,199 --> 00:01:09,302
Failing to do this makes the unit appear
to be “Off” during a dimmer check;

18
00:01:09,536 --> 00:01:13,106
as the closed shutters hide
all of the light coming from the lamp.

19
00:01:13,173 --> 00:01:17,777
Completing the circuit
is the last step in hanging a unit.

20
00:01:17,777 --> 00:01:21,047
When you plug the unit in

21
00:01:21,081 --> 00:01:24,084
be sure there is some slack to the cable
behind the instrument.

22
00:01:24,117 --> 00:01:27,720
Otherwise, if the cable is too tight,
the electrician may accidentally unplug

23
00:01:27,720 --> 00:01:30,190
the unit when trying to focus it.

24
00:01:30,190 --> 00:01:31,791
When focusing,

25
00:01:31,825 --> 00:01:36,963
use the pan screw
to adjust the unit from side to side.

26
00:01:36,963 --> 00:01:42,469
And, use the yolk locking knob
to adjust the unit up and down.
