Repair Procedures
I. Thermostat/TCO Kit
Disconnect electrical and compressed air service.
Remove the heat shield assembly by removing the two Phillips
head screws from either side of the heat shield and the one
Phillips head screw on the heat shield immediately above the
loading chamber.
The thermostat and TCO are assembled as a unit and are replaced
as such no matter which component has failed.
The Quick-Slide clips should be removed from the thermostat.
Remove the two screws holding the thermostat, and pry the
thermostat from the block. Insert new thermostat. Make sure the
rear rim of the thermostat is slipped into the slot in the heat block
before affixing screws.
The thermal cutout assembly is then removed by disconnecting the
Phillips head screw, holding the thermal cutout to the head block
on the stand off strip. Remove the other end of the thermal cutout
from the terminal strip with a small Phillips screwdriver. Procedure
is reversed to replace the thermal cutout.
