To Install a Column Module Assembly in the LTM
Oven Door
This procedure assumes that you are installing the column module into an empty location in
the LTM oven door. If installing a column module in a new location, first prepare the LTM oven
door and install the fan. See
. To remove an existing column module,
see
“To Remove a Column Module Assembly from the LTM Oven Door”
Also, a module assembly can be installed into the LTM oven door before or after attaching the
CFT unions to the columns. This procedure assumes the CFT unions are installed.
WARNING
Be careful! The oven or internal oven accessories may be hot enough to cause burns. If either
is hot, wear heat-resistant gloves to protect your hands or allow the parts to cool before
beginning the work.

Place a felt insulation gasket over the two rails and union connections on the transfer line
module. Tuck the gaskets under the retaining springs for the transfer lines so that each sits
evenly over the end face of the transfer line module. See
.
•
Do not touch the insulation to open column or union ends.
•
The tight clearance of the gasket over the retaining springs should hold it in place.
