Removing the cover from the computer
Remove the top cover of the computer as described in the computer user guide.
There are five screws: three at the back and one on either side towards the front.

Fitting the fan
I
f a working fan is not already fitted in your computer, we strongly recommend you
to fit one before using a hard disc.
Locate the bag containing the fan and its fittings.
The fan is fitted to the front left hand side of the Archimedes, just in front of the
power supply.
Take the four M4 screws and insert them, from the outside, into the four mounting
holes.
Hold each screw in place while you push a rubber grommet onto it. This helps keep
fan noise to a minimum.
Examine the fan itself. You will find two arrows: one indicates the direction of
rotation and the other the direction of air flow. Place the fan onto the four screws
with the air flow arrow pointing into the computer The wires should be next to the
power supply.
Put the filter into the filter cover and place the assembly onto the four M4 screws,
so that the filter is trapped between the fan and the filter cover. (The filter should
be replaced before it becomes clogged with dirt. Replacement filters can be
ordered in packs of ten).
Fit the four M4 nuts to secure the fan. Use a screwdriver to tighten the screws
