On the back of the cooling unit, you'll find the lid for the reservoir. Obviously, this needs to be filled. As the manual says -- fill half a bottle of the additive(150ml) in the reservoir and fill the rest with destilled water. Using destilled water and not plain tap water is very important to avoid corrosion as well as algea and bacterial growth. The use of tap water or any other additives may cause an adverse chemical reaction and void your warranty.
After filling the reservoir, start the system to remove airbubbles in your system. Shake it, bend it and twist it to make sure there are no airpockets or bubbles left in the waterblock and hoses. But before you mount the waterblock inside your computer, we recommend you test it for a few hours outside you computer to check for leaks et cetera.
When testing the system, you can spend some time familiarizing yourself with the controls of the Hydrocool. The controller inside your computer is fed with data from the cooling unit and, as we mentioned earlier, monitors the system temperature and fluid level among other things. Should the pump fail to operate properly, the alarm will go off when the temperature has reached a preset value, and eventually shut down the system. Both the alarm and shut-down temperatures can of course be manually set by the user by using the buttons on the frontpanel.

You can manually alter the preset values for the cooling unit, alarm, shut-down temperature and so on via the four buttons on the front bezel of the unit. The different buttons are:
- C: Sets the temperature to Celsius
- F: Sets the temperature to Farenheit
- Turbo: full speed on the fans.
The manual has an excellent explanation on how to manually configure your unit, so we will not detail the procedure in this review.
