6.2.3 Cleaning Air Filters
All filters should be checked monthly. If needed, filters should be cleaned/replaced (see below,
Cleaning the air filters:).
If the instrument's environment is especially dusty, the air intake filters should be checked periodically
and cleaned or replaced if needed. These filters must remain clean and unobstructed; restricted airflow
from dirty filters may cause the instrument interior to reach excessive temperatures, which can affect
results and possibly cause hardware malfunctions or failures. The filters can be cleaned and reused.
Each instrument has two filters: one is located behind the bottom faceplate on the left side (electronics
bay), and the others are located at the top edge of the cabinets (cabinet air). They can be removed
without tools.
See Figures 6-2a through 6-5.
Cleaning the air filters:
1 Wash dirty filters in a bactericidal disinfectant.
2 Place them on paper towels and dry them thoroughly (if you are going to reuse them
immediately).
3 To save time, you can replace dirty filters with a spare clean set. Wash, dry, and set aside the
removed dirty filters for the next filter replacement.
Removing the electronics bay filters (Figures 6-2a and 6-2b):
1 The top electronics bay filter is located behind an access door just to the left of the LCD
Touchscreen.
2 Pivot the access door outward away from the instrument. The door opens like a left-hinged
door.
3 To remove the filter, lift it up slightly, and then pivot the bottom outward. Lower the filter out of
the filter housing.
4 To insert a clean filter, place the top edge under the top lip of the mounting bracket. Slide the filter
up, pivot the bottom in toward the mounting bracket, and lower the filter into place.
5 The bottom electronics bay filter is located behind the bottom panel on the lower instrument.
6 To remove the panel, grasp both edges and pull the panel away from the instrument. The panel
should pop off with light to moderate force.
