5. Maintenance & Troubleshooting
The repair and maintenance of the Model 5209 includes replacement of the T3-style lamps
and quartz wind and cleaning of the reflector.
Lamp Removal, Replacement, Installation
The six T3-style lamps are installed into the Model 5209 heater when shipped from the factory.
The following procedure details the process to replace the lamps in the Model 5209 (reference
Figure 5-1, 5-2, & 5-3):
Note:
• Remove all power from the heater BEFORE attempting to install/replace the lamps.
• Allow a minimum of ½-inch (12 mm) of slack in the lamp lead so that the lead is not taut
when inserted into the lamp terminal block.
• Always take care to handle all lamps by the ceramic end seals and use clean cotton or
latex gloves to prevent contamination of the quartz lamp envelope.
1. Remove End Cover Screws (3 per end cover).
2. Remove End Covers on both ends of the heater.
3. If installed in the heater, remove the quartz
window from the heater by sliding the window out
of the slots machined into the reflector body. Take
this opportunity to clean the window using non-
abrasive cleaning solvent and clean, soft cotton
cloth (see Section 6).
