To replace the air filter in the FastIron SX-1600, perform the following tasks.
1.
Loosen the captive fasteners in the front of the filter retainer.
2.
Pull the filter retainer away from the chassis as shown in the figure above.
There is a hook on the back of the retainer that is attached to the grab-strap. As you pull the retainer out, the filter is pulled along
with it.
3.
Unhook the filter retainer from the air filter and discard the used filter.
4.
Partially insert the replacement air filter (part number 11211-401) by sliding it along the metal guides.
The filter is marked with an arrow. The arrow indicates how the filter should be installed in regards to the direction of airflow in
the chassis. Since air is pulled through the chassis, the arrow must point up towards the fan tray.
5.
Attach the hook on the back of the filter retainer to the filter grab-strap.
6.
Push the filter retainer into the chassis and tighten the captive fasteners.
