Disconnecting The Liquid Cooling System Hoses - Christie Boxer 4K Series Service Manual

2. Open the Service door on the side of the projector.
3. To adjust the convergence knobs, use the 2.5 mm tool included with the projector.
If adjusting by hand without using the tool, pull out the convergence adjustment knobs to
engage them.
4. Use the Convergence test pattern to assist with adjusting the horizontal and vertical lines.
Vertical convergence and rotation is done by adjusting two knobs. Christie recommends
rotating a single knob a maximum of a quarter rotation before adjusting the second knob a
quarter rotation. For example, if using one hand, turn the left knob a quarter rotation and then
the right knob a quarter rotation, and so on. Adjusting a single knob for vertical or rotational
adjustment to an extreme before adjusting the second knob may result in the convergence
mechanism binding.
5. When complete, push in all the convergence adjustment knobs to disengage the knobs.

Disconnecting the liquid cooling system hoses

The liquid cooling system hoses are pressurized and may cause spraying or dripping when
disconnected for service.
These procedures must be followed regardless or whether the system has been powered on previously
or not.
