You will not need power tools or a tape measure to install your Koolance system, and it should even be less diffi cult than assembling your own computer. Koolance offers liquid coolers for every major hardware device. Providing enormous fl...

The heart of a liquid cooling system is the pump. This device pushes liquid through each cooler and into the heat exchanger. Koolance systems use dual pumps to increase reliability and liquid pressure. If one pump should fail, the second can help prevent potential damage caused by heat increase.

Alarm Settings By default, the Koolance audio alarm will sound if any sensor reaches 55ºC (131ºF). When the system alarm sounds, the LED temperature will fl ash in the display and the radiator fans will increase to 100% power. To change this setting for an individual sensor, choose the desired channel with SET, and press and hold ▲...
Power Connection You may begin the installation of your Koolance system by mounting a power supply in the chassis. The liquid cooling system requires approximately 11-17W from any standard ATX power supply. Connect a 12 Volt 4-pin Molex plug from the power supply to the Power Connection underneath the Radiator.
ATX Power Switch The ATX “pass through” lead is responsible for shutting off your computer if sensor channel #1 reaches 3ºC (5ºF) above the preset alarm temperature (See LED Display for alarm confi guration). Connect the male ATX power lead from the PC3-700 to the chassis main power switch.
Cooler & Tubing Confi guration Depending on the cooling blocks (“coolers”) in your Koolance system and nozzle sizes (1/4”, 3/8”, etc.), they may be connected in series, parallel, or a mixture of both for best performance. Recommended confi gurations are illustrated below.

It is not uncommon to see fi ve or more coolers in a Koolance system, but the limit is usually at what temperature you are comfortable with. Remember, liquid at higher temperatures is still considerably more effective at carrying heat than air at the same temperature.
Connecting Hoses Each tubing connection uses a threaded compression fi tting (“hose screw”) to keep it secure. To connect these components: Squeeze the tube while pushing it Thread a hose screw onto the tube fi rmly over the nozzle. Tubing should end.
Disconnecting Hoses Nozzles are designed to attach tightly. If you need to remove a hose for any reason, it may not pull off easily, even after unscrewing the compression fi tting. Usually, a connection will come free by squeezing the hose on top of the nozzle and pulling away.
Hose Lengths Before installing your liquid coolers, appropriate lengths of tubing must be cut to connect each device. It may be easier to temporarily lay your motherboard and video card inside the case to better-estimate the required amounts. Remove the threaded compression fi...

Continue connecting all of your coolers in the system until there are no longer any open tube ends. Liquid Coolers You should now install the liquid coolers (CPU, GPU, Hard Drive, etc.) to your hardware before continuing this User Manual. Please refer to your cooler kit’s individual installation instructions, then continue on to the next section.
Testing & Filling Once all of the coolers have been connected, the system can be fi lled with coolant. The refi ll tap is located on top of the reservoir. Remove the large slot-headed screw (with a screwdriver or large coin) and insert the refi ll funnel. WARNING The liquid coolant is electrically conductive.
Page 23
The liquid coolant should be fi lled up to about 1.5 cm (1/2”) from the reservoir’s top. This small gap will catch air as it circulates through the system. Do not overfi ll. It is recom- mended to keep paper towels on hand just in case. Replace the refi...
The coolant in your system should be emptied for any of the below reasons. Unless replacing the liquid coolant, it can also be reused. 1. To Keep it Clean - Koolance recommends replacing the liquid coolant about every 2 years. The coolant should also be replaced if it becomes contaminated or signifi...
Troubleshooting We hope your Koolance system will provide you with years of reliable cooling performance. To help avoid unnecessary RMA issues, we have prepared this list of possible operational problems, and their most common solutions. 1. How do I tell if the pumps are working?...
