2. Safety Information

Always prioritize safety when handling and installing high-intensity discharge lamps. Failure to follow these guidelines may result in injury or damage to equipment.

• Power Disconnection: Always ensure the equipment is completely powered off and disconnected from the main power supply before attempting any installation, removal, or maintenance.
• Eye Protection: Mercury vapor lamps emit intense UV radiation. Never look directly at an operating lamp. Ensure proper UV shielding is in place within your equipment.
• Skin Protection: Avoid direct skin contact with the lamp's glass surface. Oils from your skin can create hot spots, leading to premature lamp failure. Always use the provided gloves or clean, lint-free gloves when handling the lamp.
• Handling: Handle the lamp with care. Avoid dropping or subjecting it to physical shock, as this can cause breakage and release of mercury vapor.
• Disposal: Mercury vapor lamps contain mercury. Dispose of used lamps according to local environmental regulations. Do not dispose of them in regular household waste.
• Ventilation: Ensure adequate ventilation in the work area, especially if a lamp breaks.

4. Setup and Installation

Follow these steps carefully to install the replacement lamp:

1. Prepare the Work Area: Ensure your work area is clean, well-lit, and free from obstructions.
2. Power Off Equipment: Crucially, turn off and unplug the NuArc platemaker or silkscreen exposure equipment from the power source. Allow the old lamp to cool down completely if it was recently in use.
3. Access Lamp Housing: Refer to your NuArc equipment's original manual for instructions on how to safely open and access the lamp housing.
4. Remove Old Lamp: Wearing protective gloves, carefully remove the old lamp from its sockets. Dispose of the old lamp responsibly according to local regulations for mercury-containing products.
5. Handle New Lamp: Put on the provided protective gloves. Avoid touching the glass surface of the new lamp with bare hands.

7. Install New Lamp: Carefully insert the new Ushio lamp into the lamp sockets within the equipment. Ensure it is seated firmly and correctly according to the equipment's design. Do not force the lamp into place.
8. Secure Housing: Close and secure the lamp housing of your equipment.
9. Reconnect Power: Plug the equipment back into the power source.
10. Test: Power on the equipment and test the new lamp's functionality.

5. Operating Considerations

The wattage of this lamp (1000W) is determined by the power supply within the NuArc machine it is used in. While this lamp may sometimes be marketed as a 1200W lamp, the NuArc power supplies are designed to drive it at 1000 watts. The lamp will operate at the power level dictated by your specific NuArc equipment.

6. Maintenance

Regular maintenance helps prolong the life and efficiency of your lamp:

• Cleaning: Periodically, and always before installation, clean the lamp's glass surface with a clean, lint-free cloth and isopropyl alcohol. This removes dust, fingerprints, and other contaminants that can cause hot spots and reduce lamp life. Ensure the lamp is cool and disconnected from power before cleaning.
• Inspection: Regularly inspect the lamp for any signs of damage, such as cracks or discoloration. Replace the lamp if any damage is observed.
• Cooling: Ensure the equipment's cooling system is functioning correctly. Overheating can significantly reduce lamp lifespan.

7. Troubleshooting

If the lamp does not function after installation, consider the following:

• No Power: Verify that the equipment is properly plugged in and receiving power. Check circuit breakers or fuses.
• Improper Installation: Ensure the lamp is fully and correctly seated in its sockets. A loose connection can prevent ignition.
• Equipment Malfunction: If the lamp is correctly installed and receiving power, the issue may lie with the equipment's ballast, ignitor, or other internal components. Consult your NuArc equipment's service manual or a qualified technician.
• Lamp Failure: Although new, lamps can sometimes be faulty. If all other troubleshooting steps fail, the lamp itself may be defective.
