MAINTENANCE
Bulb Replacement NightMaster
1. Ensure power is OFF and the lamphead is cool to the touch prior to replacing the bulb.
2. Ensure the replacement bulb has the same voltage and wattage rating.
3. Loosen the two screws on each side of the lamphead. Open the glass cover (the gasket may also come off).
4. Slide the bulb sideways into the spring contact and lift it out from the opposite side.
Note:
When handling the new bulb avoid touching it except on the flat seal at either end. (Grease or oily fingerprints can cause
damage the quartz bulb.) If the bulb is accidently touched, gently wipe it clean with alcohol.
5. Check both lamp base contacts to be sure they are perfectly clean.
6. Push one end of the bulb into the spring contact until the other end can be placed into the opposite contact. Rotate the lamp
back and forth about its axis to ensure adequate seating of contacts.
Caution:
Do not operate the light with the front glass removed.
7. Ensure the gasket is in place. Close the glass cover and tighten the two screws. Do not over tighten the screws.
Note:
Bulb life is extended when the lamphead is mounted so the bulb is mounted in a horizontal position.
