Maintenance
To maintain optimum performance and minimize wear fixtures should be cleaned frequently. Usage and environment are
contributing factors in determining frequency. As a general rule, fixtures should be cleaned at least tw ice a month. Dust build up
reduces light output performance and can cause overheating. This can lead to reduced lamp life and increased mechanical wear. Be
sure to power off fixture before conducting maintenance.
Unplug fixture from power. Use a vacuum or air compressor and a soft brush to remove dust collected on external vents and internal
components. Clean all glass w hen the fixture is cold with a mild solution of glass cleaner or Isopropyl Alcohol and a soft lint free
cotton cloth or lens tissue. Apply solution to the cloth or tissue and drag dirt and grime to the outside of the lens. Gently polish
optical surfaces until they are free of haze and lint. Do not to touch the lamp glass when cleaning fixture. Oil and dirt can cause
damage and premature aging of the lamp. In the event that the lamp is touched or becomes dirty, clean the lamps with an alcohol
wipe.
DMX Primer
There are 512 channels in a DMX-512 connection. Channels may be assigned in any manner. A fixture capable of receiving DMX
512 will require one or a number of sequential channels. The user must assign a starting address on the fixture that indicates the first
channel reserved in the controller. There are many different types of DMX controllable fixtures and they all may vary in the total
number of channels required. Choosing a start address should be planned in advance. Channels should never overlap. If they do, this
will result in erratic operation of the fixtures whose starting address is set incorrectly. You can however, control multiple fixtures of
the same type using the same starting address as long as the intended result is that of unison movement or operation. In other w ords,
the fixtures will be slaved together and all respond exactly the same.
DMX fixtures are designed to receive data through a serial Daisy Chain. A Daisy Chain connection is w here the DATA OUT of one
fixture connects to the DATA IN of the next fixture. The order in w hich the fixtures are connected is not important and has no
effect on how a controller communicates to each fixture. Use an order that provides for the easiest and most direct cabling. Connect
fixtures using shielded tw o conductor tw isted pair cable with three pin XLR male to female connectors. The shield connection is pin
1, while pin 2 is Data Negative (S-) and pin 3 is Data positive (S+). CHAUVET carries 3-pin XLR DMX compliant cables, DMX-10
(33’), DMX-4.5 (15’) and DMX-1.5 (5’)
Returns Procedure
Returned merchandise must be sent prepaid and in the original packing, call tags will not be issued. Package must be clearly labeled
with a Return Merchandise Authorization Number (RA #). Products returned w ithout an RA # will be refused. Call CHAUVET and
request RA # prior to shipping the fixture. Be prepared to provide the model number, serial number and a brief description of the
cause for the return. Be sure to properly pack fixture, any shipping damage resulting from inadequate packaging is the customer’s
responsibility. CHAUVET reserves the right to use its ow n discretion to repair or replace product(s). As a suggestion, proper UPS
packing or double-boxing is alw ays a safe method to use.
Claims
Damage incurred in shipping is the responsibility of the shipper; therefore the damage must be reported to the carrier upon receipt of
merchandise. It is the customer's responsibility to notify and submit claims w ith the shipper in the event that a fixture is damaged due
to shipping. Any other claim for items such as missing component/part, damage not related to shipping, and concealed damage,
must be made within seven (7) days of receiving merchandise.
Fixture Cleaning
The cleaning of internal and external optical lenses and/or mirrors must be carried out periodically to optimize light output. Cleaning
frequency depends on the environment in which the fixture operates: damp, smoky or particularly dirty surrounding can cause greater
accumulation of dirt on the unit’s optics.
Clean with soft cloth using normal glass cleaning fluid. - Always dry the parts carefully. - Clean the external optics at least every 20 days.
Clean the internal optics at least every 30/60 days.
