LAMP REPLACEMENT / INSTALLATION

BEFORE REPLACING THE LAMP, THE UNIT MUST BE "OFF" FOR A MINIMUM OF 5

MINUTES. THIS WILL ALLOW DANGEROUS CHARGES, WHICH ARE PRESENT FOR

PROPER LAMP OPERATION, TO BLEED OFF.

LAMP REPLACEMENT PROCEDURE

1. Allow the unit to cool before removing the lamp/reflector assembly.

2. Unplug the power cord.

3. Remove the cover screws and cover.

4. Disconnect the lamp electrode wire from the positive electrode clip. Do not disconnect the

wire from lamp.

5. Loosen the retaining nut (see Figure 1.1) and rotate the electrode to one side such that the

lamp/reflector assembly can be removed from mount. Remove the lamp/reflector assembly.

6. Install the new lamp/reflector assembly into the mount and move the negative electrode (see

Figure 1.1) into position. Tighten the screw. Do not bend the electrode to install the new

lamp/reflector assembly.

7. Attach the electrode wire to the positive electrode clip (see Figure 1.1).

8. Replace the housing cover on the unit. If access to the unit is limited, use Allen head

screws instead of thumbscrews.

9. Record the serial number of the unit and hour-meter reading on the Bulb History Record.
