MAINTENANCE
Bulb Replacement
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. (If there
are two bulbs installed, each bulb will be half the listed wattage.)
3. Remove the wire guard. Squeeze top to bottom and slip out of bezels.
4. Hold the glass in place while removing the bezels. Remove the four cap head
screws and remove the bezels. Remove the glass.
Note:
Gasket is attached.
5. 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.
6. Check both lamp base contacts to be sure they are perfectly clean.
7. 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.
8. Hold the glass in position. Ensure the glass is inside the lip on all four sides.
9. Install the bezels and secure with the four screws.
10. Install wire guard.
Note:
Bulb life is extended when the lamphead is mounted so the bulb is in
a horizontal position.
Cleaning
High intensity lights may, over time, develop a powdery white film on the reflector.
If this happens remove the glass (see bulb replacement procedure) and gently wipe the
refelctor clean with a soft cloth.
