Maintenance
6.1
Cavity Life
The life expectancy of the cavity depends on the time and temperature of operation. The higher
the temperature, the shorter the life span. At temperatures near the upper end of the range,
the life expectancy is shortened by approximately 30%.
6.2
Safety Interlocks
Automatic shut-down will occur if the region near the cavity housing exceeds ~115 °C. This
thermal fuse must be replaced when over-temperature causes a shut down. The cooling fan will
operate when power is on.
6.3
Periodic Inspections
Check periodically and upon every start up for unusual noises and smells when applying power.
6.4
Fuse Locations
The M310 has one or two fuses. Refer to the table below.

Cleaning
Clean the outside of the cabinet with mild soapy solution and water only. Do not attempt to
clean the emitter plate.
6.6
Heater Element Replacement
The M310-HT heating element is
not
field replaceable since the cavity and elements are an
integral assembly. Contact LumaSense for service if the heating element fails. (Check continuity
of the thermal fuse first.)
