Setup & Operation
Unpacking
Unpack the fixture and carefully inspect for any signs of physical damage. Report any damage to Wildfire or
your local distributor immediately. Included with each unit should be the following items:
1. Pipe mounting clamp, designed to attach the fixture to a 11/2” to 2” pipe truss
2. Safety Cable, Provided to secure the fixture when mounted on a pipe truss
3. Wildfire IronArc™ Lamp, Model LMP-250D
Before mounting the fixture you will need to install the lamp refer to Lamp Replacement on page 6 for correct
installation.
Installation
After installing the lamp place the fixture in desired location the fixture is equipped with a yoke assembly for
mounting. The yoke may be fitted with either a pipe clamp (included) for mounting on a pipe truss or a baby bail
block or junior pin for mounting on a light stand.
If the fixture is mounted on a pipe truss be sure to use the included safety cable looping it through the yoke
assembly and around the pipe truss this will prevent the fixture from falling and possibly causing injury in the
event that the pipe clamp was not securely tightened.
To adjust the angle of the fixture loosen the knobs on either side of the unit slightly, rotate to desired angle and
tighten. Care should be taken to support the front of the fixture while loosening the knobs to prevent the fixture
from rotating forward and possibly causing injury.
The fixture comes standard with a 7.5” Bracket assembly for attaching dowsers and scrollers such as Wybron’s
Eclipse or Coloram Series as well as barndoors and other accessories. When using accessories with this fixture
be sure to attach the safety cable provided by the accessory manufacturer to the fixtures yoke assembly.
Plug the fixture into the appropriate power source. If you are controlling the unit with a lighting control board you
will need to make sure it is plugged into a non-dim circuit if the fixture is plugged into a dimmable circuit it will
not operate.
Operation
To strike the fixture push the power/breaker switch to the on position Allow at least 2 minutes for the lamp to get
to full brightness. Once the fixture has been powered up and the lamp has ignited if you shut it off and try to turn
it back on the hot re-strike prevention circuitry in the ballast will prevent the lamp from striking until it is
completely cooled (approximately 5 minutes). If the power/breaker switch is left in the on position during this
cool down period the lamp will strike automatically once it has cooled sufficiently. The ballast is also equipped
with automatic lamp failure protection circuitry that shuts the fixture down if the lamp should fail for any reason,
preventing any damage to the fixture. In addition the ballast is equipped with high temperature protection
circuitry that shuts the fixture down if the ballast case temperature exceeds 85 C when the fixture cools it will
strike again automatically.
Lamp Timer
The fixture is equipped with a lamp timer that counts the number of hours the fixture is on. The timer will only
operate when the fixtures power switch is turned on. This is used to determine when the lamp needs replacing.
Wildfire recommends replacing the lamp every 1000 hours for maximum effect. The timer will automatically
reset to zero upon reaching 9999:59:59. If you need to reset it manually depress the small button on the timer.
5

DMX Control
If your fixture is equipped with DMX control you can switch the fixture on or off via a DMX 512 signal by setting
the DMX address switch on the back of the fixture to the desired address (001 to 512). Once the fixture receives
a DMX 512 data signal above 60% (153-255) the lamp will ignite. If the data signal falls below 40% (0-101) the
lamp will extinguish. Setting the DMX address on the fixture to 601 bypasses the DMX control and allows you to
switch the fixture on or off manually. The DMX input connector pin configuration is: Common Pin 1, Data Minus
Pin 2, and Data Plus Pin 3. Pins 4 and 5 are not used at this time.
Maintenance and Troubleshooting
Lamp Replacement
Unplug the fixture. Remove any accessories from the front. Make sure the fixture is cool to the touch before
opening the front lens assembly cover. Unhook the clasps on either side of the fixture allowing the front lens
assembly cover to swing down. Grasp the lamp in the center remove it by pushing it gently to one side sliding
the other end forward. Reverse this procedure to install the new lamp. After installing gently rock the new lamp
back and forth to insure the depressions on the ends of the lamp are firmly seated on the posts of the sockets. If
the lamp is not firmly seated arcing could occur melting both the socket and lamp. Care should be taken not to
touch the new lamp directly use a cloth or glove when handling if you have touched the lamp it must be cleaned
with alcohol to remove any oils and fingerprints prior to striking. For maximum UV-A output always use Wildfire
IronArc™ lamps, and change the lamp in your fixture every 1000 hours.
Cleaning
For best performance, the reflector, lamp and filter lens should be kept free of dirt and dust. At no time should
any cleaning chemicals or abrasives be used to clean any part of the fixture. Do not spray or apply any liquid
directly to any part of the fixture. Always unplug the unit. before cleaning. For normal cleaning, a dry soft cloth
should be used to wipe any surface free from dust and light dirt. Cleaning the reflector will require that the lamp
be removed. Remove the lamp by following the instructions listed under lamp replacement above. Once the
lamp has been removed, gently wipe off the reflector using a soft dry cloth. In the event the reflector is heavily
soiled, lightly dampen the cloth with a mild window cleaning agent and wipe clean. The filter lens can be cleaned
in the same manner. The lamp should be cleaned with alcohol only.
Troubleshooting
Other than the lamp, there are no user serviceable parts in the fixture.
The fixture will not strike – Check to make sure there is power to the fixture. Make sure the power/breaker
switch on the back of the fixture has not been tripped. Unplug the unit. Check to see if it has a lamp installed
and that it is seated properly in the sockets (see lamp replacement above). Check to see if the safety cutoff
switch is making contact by closing the lens cover and listening for a clicking sound. If the fixture still is not
striking try replacing the lamp. If you have checked all of the above and the fixture still won’t strike contact
Wildfire technical support at [phone] or your local distributor.
The effect is not working anymore – Try changing the lamp. The lamp in your Wildfire fixture is rated at 1000
hours. This does not necessarily mean that the lamp will “burn out” or not light after 1000 hours it may continue
to burn for much longer period of time however the amount of UV it produces will be reduced considerably
causing the effect to appear as though it isn’t working. Wildfire recommends for maximum effect to change the
lamp every 1000 hours.
