6.1 LAMP
REMOVAL/REPLACEMENT/INSTALLATION: The lamps are
included with the Model 6020 heater, but are shipped separately to avoid breakage. The
following procedure details the process to install or replace the lamps in the Model 6020
(reference Figure 6-1):
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.
2. Remove end covers on both ends of the heater.
3. Pull the lead wires out of the wire nuts. (see Figure 6-1).
