16. FLM LIQUID COOLING CIRCUIT
About this chapter
This chapter describes how to diagnoses and to maintain the liquid cooling circuit of the FLM projector.
WARNING: All procedures in this chapter may only be performed by “qualified service technicians” .
WARNING: All actions performed on the liquid cooling circuit should occur in ambient conditions (25°). The
projector should have sufficiently cooled down (minimum 2 hours).
WARNING: Do not change the air pressure of a calibrated liquid cooling circuit (see marking on pressure
vessel), unless stated explicitly in the servicing procedure.
