Access Panels
The chamber module is covered by two access panels: the right side
panel and the left side panel. The door is covered by the door panel. All
are attached to the chassis (or door) by screws. Side panels must be
removed and reattached in a specified order, as some panels cover access
to screws securing other panels.
Door Assembly
Heaters with an integrated thermostat provide the heat input to the door
to maintain its temperature at a predetermined control point. Temperature
sensors are used to monitor the door temperature and provide feedback to
the computer to properly control the heaters. Thermostats will cut off the
power to the heaters if temperature limits are exceeded.
