Step 4: Attach the new yoke that has been provided with Source Four Par Dimmer kit using the new hardware that has
also been provided.
Step 5: Loosen the knurled bolt on the back of the lamp burner then pull the lamp burner out of the fixture. This lamp
burner is no longer required. A new lamp burner is provided with the Source Four Dimmer kit.
Step 6: Remove the HPL lamp from the lamp burner. Store the lamp in a safe place for re-installation later.
NOTE: To avoid premature lamp failure, do not touch the lamp glass. If you do, clean it carefully with
isopropyl alcohol and a clean lint-free cloth. Allow the lamp to dry completely before operation.
Step 7: Using the two remaining bolts provided in the Source Four Dimmer kit, attach the Source Four Dimmer to the
outside of the newly installed fixture yoke.
NOTE: The fixture yoke offers one set of access holes on one side for Dimmer attachment. Mounting
holes are provided on the Source Four Dimmer to allow horizontal or vertical mounting to the
fixture yoke. ETC recommends installing the Dimmer in a vertical orientation with the user
interface parallel to the yoke (directed up or down). Alternative installation can be perpendicular
to the yoke (with the user interface facing towards the front or back).
CAUTION: Do not install the Source Four dimmer positioned above a fixture that is in a yoke out position.
Dimmer overtemp and failure may occur.
Step 8: For Source Four dimmers with bare-end power input cables, attach a grounding-type attachment plug with
integral cord grip rated for 120v or 240v and at least 15 amps.
Step 9: Replace the lamp to the new lamp burner. Reference the related fixture user manual for instructions to “replace
the HPL lamp: and ”center the lamp and adjust the field”.
Step 10: Reinstall the lamp burner by aligning the bolt hole and tightening the knurled bolt.
