Section 6 – MAINTENANCE

The repair and maintenance of the Model 5194 includes replacement of the T3-style lamp
and quartz window and cleaning of the reflector.

6.1 LAMP

REMOVAL/REPLACEMENT/INSTALLATION: The T3-style lamp

is installed into the Model 5194 heater when shipped from the factory. The following
procedure details the process to replace the lamps in the Model 5194 (reference Figure 6-
1, 6-2, & 6-3):

Note:

Remove all power from the heater BEFORE attempting to install/replace the

lamp.

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 (2 per end cover).
2. Remove end covers on both ends of the heater.
