Maintenance32 Air filter, lens and main unit cleaning CAUTION If you use the projector mounted on the ceiling, ask the dealer to carry out the maintenance such as cleaning. Cleaning the air filter The filter under the air filter cover is the device to shut out dusts or dregs. Do not use the projector with the filter taken off. Give a frequent clean especially to the air filter. (The cleaning period is once per about 50 hours). 1) Unplug the power cord. 2) Take off the air filter cover. The filter is on the right side of the projector. Pull up the filter tabs. 3) Clean the air filter cover. Remove dust and stains with a vacuum cleaner. CleanerÕs nozzle 4) Attach the air filter cover. Notes ¥ When the air filter is dusty, the ventilation is impaired. This causes the temperature inside the projector to rise, and may damage the unit. ¥ Attach the air filter cover firmly after the cleaning. If it is not set correctly, the dusts will enter and they will be projected and overlapped on the picture. Cleaning the lens Use a blower or a lens cleaner to clean the lens. Never rub or tap the lens with a hard object as the lens surface is fragile. Cleaning the main unit ¥ Pull out the power cord before cleaning. ¥ Use a soft cloth to wipe off stains from the surface. ¥ To remove difficult stains, use a soft cloth slightly moistened with a weak solution of synthetic detergent and water, and finish with a soft, dry cloth. Replacing the intake, exhaust fans and air filter To maintain the efficiency of the projector, replace the intake and exhaust fans about every two to three years. Ask the dealer for the replacement.
33Maintenance Lamp replacement The lamp will eventually begin to project dark or dull pictures and finally will not light up. (LampÕs life length depends on the use condition.) In such a case, replace the lamp with new one.1 2 1 2 2 1 3 2 1 Take off the lamp cover on the bottom panel. Loosen two screws, and pull off the lamp cover. Pull out the lamp. Loosen the two fixing screws, and lift up the handle to pull out the lamp. Load a new lamp. Slide until it hits the bottom and tighten the two fixed screws. Attach the lamp cover. Slide the cover in place and tighten two screws. Reset the lamp timer. Refer to the lamp instructions for resetting. Notes ¥ The projector displays the total working time at every 1,000 hours (only when plugged in and turned on; ex. Ò >1000H Ó, Ò >2000H Ó). ¥ The lamp should be replaced if the total working time exceeds about 2,000 hours. ¥ Attach the lamp cover firmly after replacing the lamp. If it is not set correctly, the power will not turn on. ¥ Use a new lamp when replacing it. ¥ The lamp is made of glass and is very fragile. Do not touch the lamp with your bare hands and do not jolt or damage it. Do not use an exhausted lamp. Unplug the power cord. Wait until the lamp gets cold enough. 6 7 1 23 4 5 CAUTION ¥ If you use the projector mounted on the ceiling, ask the dealer to carry out the maintenance such as cleaning or replacement of the lamp. ¥ When replacing, always use lamp ÒTLPL8Ó (sold separately). For detail, refer to TLPL8 instruction. ¥ If you have been using the projector, the lamp will be very hot, and may cause burn injuries. Wait for the lamp to cool (for longer than 1 hour) before replacing it. ¥ If the lamp should break, please handle with care to avoid injury due to broken pieces and contact your dealer for repair service.
