5.2 MAINTENANCE REQUIREMENTS
5.2.1 MODELS 105, 108, 112, 305, 308, & 312-AMX
The Models 105-AMX, 108-AMX, 112-AMX, 305-AMX, 308-AMX, and 312-AMX require
calibration once every six months as regular maintenance. Refer to Section 6 for details.
5.2.2 MODELS 125, 140, 160, 320, 345, 360, 390 and 3120-AMX
The Models 125, 140, 160, 320, 345, 360, 390, and 3120-AMX require maintenance once every
three months. Maintenance of these models consists of cleaning the fan filter. It is important
that this filter is kept clean in order to insure proper cooling of internal components. Loss of
available power and over-temperature shutdown may result from a dirty or clogged filter.
The fan filter is cleaned as follows:
1. Slide the chassis forward to reveal the fan filter access panel, located on the
bottom of the chassis, immediately behind the front panel of the unit.
2.
Remove the fan filter access panel. (The 320-AMX has no access panel.
Loosen the 2 screws that partially protrude from the side panels, directly above
the filter, to allow the filter to slide out of its holder.)
3. The filter will slide out of its holder. Remove the filter.
4. Wash and dry the fan filter. The filter is a metal screen mesh type. It is
reusable and is best cleaned by washing with warm soapy water. Make sure
that the filter is dry before installing it into the chassis.
5. Install the filter and then replace the fan filter access plate or remaining screws.
6. Slide the chassis back into its normal position.
If system operation is suspect or the calibration interval has passed, perform the calibration
procedure outlined in Section 6.
