1. Liqui d Cooling Ci rcuit T o oh i g ha m b i e n tt e m p e r a t u r e An Error or warning message “Ambient temp high” is displayed on the local LCD pa nel or touch panel. See manual of the projector for accessing error messages. Possible cause Solution Ambient temperature of the projector is too high.
1. Liquid C ooling Circ uit Possible cause Solution Defect pump. When the projector is running, you don’t feel any vibrations when touching the pump Drain the liquid cooling circuit, replace the pump, fill and pressurize the liquid cooling circuit. T i p: It’ s not ne cessary to drain the cooling circuit of the light processor .

2. Servicing the liquid coo ling circuit 2.1 Preparation for cooling liquid replacement What has to be done 1. Switch off the projector . 2. Remove the lamp unit to access the cooling liquid in- and outlet. 3. If excluding the light processor is required w hile handling the co oling circuit procedures, disconnect the circuit at the flow switch (a).
2. Servicing t he liquid coolin g circuit OUT Image 2-3 Drain complete circui t 2. Close the valve. 3. Fill the syringe with air . Press in the valve of the male fitting when extracting air . Image 2-4 4. Couple the air filled syringe to the inlet of the cooling circuit and force air into the circuit via the syringe.
2. Servicing the liquid coo ling circuit 2.3 Filling the liq uid cooling circu it This procedure can only be used to fill an e mpty (drained) coo ling circuit. Necessary t ools • 60 cm of plastic tube with male valved fitting. • 60 cm of plastic tube with fe male valved fitting.
2. Servicing t he liquid coolin g circuit ab c d e f M F Image 2-7 4. Couple the filled syringe to the inlet of the cooling circuit and press the cooling liquid inside the circuit. Caution: Position the empty bottle above the liquid circuit (on top of projector).
2. Servicing the liquid coo ling circuit 2.4 Refreshing the liquid cooling circuit Over time the cool ing liquid may show d eterioration and hen ce less effective cooling ch aracteristics. T o m ain- tain sound cooling properties, we advise ANNUAL replac ement of the cooling liquid.
2. Servicing t he liquid coolin g circuit OUT IN Image 2- 10 Refresh cooling circ uit 5. Switch on the projector . After projector boot-up procedure, the in ternal pump will automatically start sucking-up the fresh liquid Note: Make sure that the end of the plastic tube remains immersed in the bottle with fresh cooling liquid.
2. Servicing the liquid coo ling circuit b ac d M F F M Image 2-1 1 Caution: It’s important that there is no air i nside the tube. The pump is not self priming and hence i s only capable of sucking through small volumes of air. 3. Push the male valved fitting of the filled tube into the inlet of the cooling circuit.
2. Servicing t he liquid coolin g circuit 7. Uncouple the two plastic tubes. Note: Make sure that both ends of the plastic tubes in the bottle remains immersed until the plastic tubes are uncouple from the li quid c ooli ng cir cuit . Tip : Sometimes a little cooling liquid will be spilled.
2. Servicing the liquid coo ling circuit ab c d e f M F Image 2- 13 2. Couple the syringe to the inlet of the cooling circuit and press t he cooling liquid inside the circuit until the manom eter indicates 1 bar pressure. Ensure that no air bubbles are injected into the circuit.
2. Servicing t he liquid coolin g circuit Check within 24 hours whether th e pressure has stabilized close to 1 bar . If not, search for leak age. 2.7 Calibrating the liquid cooling circuit T o check .
2. Servicing the liquid coo ling circuit ab c d e f M F Image 2- 16 3. Fill the pressure vessel with liquid as follows: a) Couple the syringe with the inlet of the cooling circuit. b) Increase the pressure by pushing in the piston of the syringe (maximum 1 bar indi cated on the m anometer).
2. Servicing t he liquid coolin g circuit 4. Now that the pressure vessel is liquid filled you have to increase the pressure to 1 bar by pushing in the piston of the syringe. Then immediately extract 75 ml back into the syringe by doing the following: a) T aking note of the liquid level already in the syringe, release the plunger .
2. Servicing the liquid coo ling circuit The air hose fitting of the air pump mu st be of the Shrader valve type (A) to match with the pressure vessel, so the Presta valve type (B) has to be removed. Futhermore, the pin (C) inside the Shrader valve has to be removed as well.
An important point after buying a device Barco XLM (or even before the purchase) is to read its user manual. We should do this for several simple reasons:
