right-hand side of the lamp under its clips on the right-hand side of the lamp compartment. Allow the
spring tension to push the lamp back to the right.
11. Check that the lamp is held securely in its clips on both sides, then tighten the lamp slider locking screw
12. Connect the high-tension lamp wires to the spade connectors on the left-hand side of the lamp.
13. You will save time if you carry out lamp adjustment (see next section) now, if possible. Otherwise we
recommend that you check lamp adjustment and if necessary adjust the lamp before the fixture is used
again.
14. Check that the rubber lamp compartment seal and seal channel on the back of the head are perfectly
clean, and push the seal onto the back of the head so that the lip in the seal locates in the channel and
the flat side of the seal faces outwards.
15. See Figure 11. Reinstall the rear cover safety wire and rear cover fan connector.
16. Reinstall the rear cover on the back of the head. Use a torque driver and tighten the four rear cover
retaining screws to a torque of 0.8 – 0.9 Nm (0.6 – 0.66 ft. lb.). This will compress the lamp compartment
seal correctly.
17. If you have not been working in dry conditions (relative humidity <50%), reduce internal condensation by
carrying out the de-humidifying procedure described in “Dehumidifying the fixture” on page 15.
18. To make sure that the fixture is correctly resealed to its original IP65 level, carry out a vacuum test as
described in “Dehumidifying the fixture” on page 15.
19. Each time you install a new lamp, reset the lamp lifetime counter in the fixture’s control panel.
Send used lamps to a specialized waste disposal center. Do not dispose of them with household or office
waste.
Lamp adjustment
Warning! Read “Lamp safety” on page 5 before adjusting the lamp.
Start the lamp adjustment procedure with the fixture cool. The fixture may become hot during
adjustment, so wear heat-resistant safety gloves that also provide protection from electric shock.
The lamp wiring and connectors carry high voltage, so do not touch them with a tool or with any
part of your body.
Important! If the fan in the rear cover is disconnected, you have two minutes to carry out lamp
adjustment before the fixture shuts down power to the lamp. If two minutes is not enough and lamp
power is shut down before you have finished adjusting the lamp, you must power the fixture off and
on again before you can re-strike the lamp. Disable pan and tilt when powering the fixture on by
pressing the MENU and ENTER menu buttons together for a few seconds immediately after applying
power.
As well as giving uneven projection, a significant hot-spot in the beam will focus extra heat onto optical
components and may cause damage that is not covered by the product warranty.
After installing a new lamp, adjustment may be required to obtain an even beam.
To adjust the lamp:
1. If the fixture has been in use, shut down power to the fixture and allow it to cool for at least 60 minutes.
2. Apply power to the fixture and allow it to reset.
