PREFACE THE STRONG HIGHLIGHT II Xenon ... - Iceco.com

MAINTENANCEWARNING: OPEN AC DISCONNECT BEFORE SERVICING UNIT.THE STRONG HIGHLIGHT II CONSOLE requires very little maintenance to keep it ingood working order. Routine cleaning of the equipment is the most important element, and cleaning intervalsare determined by the dirt and dust conditions at the installation site.THE REFLECTOR should be cleaned with a soft, clean, dry cotton cloth every two weeks. Ifexcessively soiled, a commercial liquid glass cleaner may be used. Use no abrasives. Exercise extreme carenot to scratch or fingermark the coated surface.CHECK ALL ELECTRICAL CONNECTIONS periodically for tightness. Particular attentionshould be paid to the DC connections at the bulb, the shunt, and the positive binding post.THE BULB should be checked regularly for presence of dirt or foreign material on theenvelope. Dirt or foreign material must be removed from the bulb immediately, or they will burn into thequartz envelope and shorten bulb life. NOTE: Observe all safety procedures when working around the bulb.THE INSIDE of the lamphouse compartment and the blower intakes should be cleanedperiodically, depending on the dust conditions at each installation. Keep all air inlet grilles clean and freefrom obstructions.BOTH THE FRONT AND TOP LAMPHOUSE BLOWERS require periodic lubrication.Oil holes in the blower motor end bells are marked, and use of a squeeze-type, plastic injection oiler isrecommended. NOTE: blower motors are thermally protected, and failure to routinely service them couldcause overheating and periodic shutdowns. Interruption of the air flow will open lamphouse interlockswitches and extinguish the xenon bulb.TO EXPOSE THE OIL HOLES of the front blower, dismount the motor cover by removingthe two mounting screws. Both oil holes of the top blower motor are accessible by removing the frame andgrille assembly from the off-operator side of the top blower cover. Apply a few drops of machine oil in eachoil hole once or twice a year. Wipe off excess oil to prevent dust attraction.TWO SIX-INCH BLOWERS at the bottom of the off-operator side panel are required onlywhen the console uses a high reactance xenon power supply. These blowers, like the built-in blowers usedin the switching power supply, utilize sealed bearings and require no lubrication.HL2/018
