M330 Manual Service 34
6.6 Field Modification for Low Heat Rate
Warning: Electrical Shock Hazard! This equipment is to be serviced by trained
personnel only.
This procedure is to remedy a problem if the over-temperature cut-off switch causes the M330
to disconnect heater power before reaching 1700 °C. Newer models have the cut-off switch in
the “new location” and this procedure does not apply.
1. Remove the M330 Rear Panel.
2. Relocate the Over Temperature Manual Reset Thermostat as shown below. Drill two
holes in top cover sheet metal and use self tapping screws to attach. This allows the
M330 to go to 1700 °C.
