______________________________ Installation A. Preparation 1. Shut down the computer, and disconnect it from the mains electricity supply. 2. Leave the computer to cool down, and then remove the existing CPU heat sink. Warning: If the computer has been in use the CPU area may be very hot. Do not touch any parts until you are sure they have cooled down. B.
1. Apply a very thin layer of silicone compound (from the small sachet) to the surface of the CPU. 2. Position the AC4G-D cooling unit on the CPU so that the cold plate sits squarely over the CPU. Warning for AMD: The cooling unit for AMD has a small step in the base. When positioning this unit, you must ensure that the step of the cooling plate sits on the raised part of the CPU socket (see figure below). Failure to do so will void the warranty, result in poor cooling, and could damage the CPU.
3. Making sure that the front of the bay unit is flush with the front of the PC, screw the bay unit into position using the 4 supplied screws (2 on each side of the bay). 4. Connect the bay unit's USB cable connector (female) to the USB connection on the motherboard (male). Note: The motherboard USB connector has 9 pins. Make sure that you position the bay unit's connector correctly so that all 9 pins are connected. 5.
9. Put the PC cover back on. Installation is complete. _______________________________ Operation In order for any cooling system to work efficiently there must be free air flow around the PC case.

The LCD display When you switch your computer on, Mode 1 (Extra-quiet) is activated by default. The AC4G-D LCD display shows the temperature of the CPU and the current fan level. Note: Fan level (or speed) is not the same as mode. Each of the four modes controls fan speed in a different way, but each uses all four fan levels. If you notice that fan level is continuously high, you may decide to switch to a cooler mode. Switching between modes 1.
__________________________ Troubleshooting The blue LED on the AC4G-D bay is on continuously during normal operation. A different state indicates a problem.
