Replacing the HPL lamp
A lamp must be installed before you use the luminaire.
Step 1: Disconnect power to the Source Four luminaire before installing the lamp.
Step 2: Loosen the knurled bolt on the back of the lamp housing and pull the housing out.
Step 3: Holding by the base, remove the HPL lamp from its box.
Step 4: Align the flat sides of the lamp base with the retention brackets on either side of the
socket as shown in Figure 3 .
Step 5: Push down on the lamp base until the lamp seats firmly. When properly installed, the top
of the lamp’s base will be even with he top edges of the retention brackets.
Step 6: Press lamp retaining clip across lamp base to secure.
Step 7: Reinstall the lamp housing by aligning the bolt hole and tightening the knurled bolt.
N o t e : Verify that the HPL lamp you intend to install is suitable for your facility’s voltage;
115-, 120-, 230-, and 240-volt HPL lamps are available. See HPL lamp table, page
4 . Operating HPL lamps above their rated voltage reduces lamp life and can cause
premature lamp failure.
W A R N I N G : Let the lamp cool before replacing.
C A U T I O N : Use caution when installing or replacing any lamp.
When installing/replacing lamp, be sure to point the lamp away from your face and
away from others before inserting it firmly into the assembly.
This may prevent injuries if the lamp should break.
N o t e : To avoid premature lamp failure, do not touch the lamp glass. If you do, clean it
carefully with isopropyl alcohol and a clean lint-free cloth. Allow to dry before
operation.
C A U T I O N : Improperly installed lamps cause premature lamp failure and socket problems.
