Interior Cleaning
Use a dry, low-velocity stream of air to clean the interior of the chassis. Use
a soft-bristle brush for cleaning around components.
Exterior Cleaning
Cautions
Avoid getting moisture inside the chassis during exterior cleaning, especially
through the top vents. Use just enough moisture to dampen the cloth.
Do
not
wash the front- or rear-panel connectors or switches. Cover these components while
cleaning the chassis.
Do
not
use harsh chemical cleaning agents; they may damage the chassis. Avoid chemicals
that contain benzene, toluene, xylene, acetone, or similar solvents.
Clean the exterior surfaces of the chassis with a dry lint-free cloth or a
soft-bristle brush. If any dirt remains, wipe with a cloth moistened in a mild
soap solution. Remove any soap residue by wiping with a cloth moistened
with clear water. Do
not
use abrasive compounds on any part of the chassis.
Cleaning and Replacing the Fan Filters
Dirty fan filters can dramatically reduce the cooling performance of the
PXI-1044 chassis. Clean the filters whenever they become visibly dirty.
You can easily remove the chassis air filters from the rear of the chassis by
removing the filter retainer. To remove the filter retainer, loosen the
retainer screws. The filter cover and retainer are shown in Figure 1-2,
Clean the fan filters by washing them in a mild soap solution and then
vacuuming or blowing air through them. Rinse the filters with water and
allow them to dry before reinstalling them on the chassis.
If desired, you can replace the fan filters with part number FF 450-A/30P
from Air Filtration Products, Inc., Tucson, AZ 85705.
The same filter media can be purchased in sheets, and a rectangular section
of this material can be used instead of three separate filters.
