This User Manual is updated regularly. Please be sure to check our support page for a newer version of this guide: www.koolance.com/support GENERAL PRECAUTION Please read this manual carefully before beginning the installation of your Koolance system. This manual assumes the user has basic experience in building and configuring computer systems. Information referring to traditional hardware assembly is intentionally brief.
! WARNING: The Koolance liquid & coolant pack contain chemicals which may be harmful or fatal if swallowed. KEEP THIS AND ALL DANGEROUS CHEMICALS OUT OF THE REACH OF CHILDREN. If ingestion has occurred, seek medical attention immediately. Give two glasses of water. Do not induce vomiting. In the case of eye contact, flush eyes immediately with water for 15 minutes. Remove contact lenses. Call a physician if irritation persists.

the ▼ or ▲ buttons to adjust pump settings, or hold down an arrow to skip to the lowest or highest mode directly. There is no automatic mode for the pump.
Positioning the Cooling System External Nozzles & Power Cable The cooling system is designed to operate in various locations, but it must run upright. Reservoir air filtration is not possible in all orientations. Install the nozzles you purchased for your cooling system. It’s recommended to hand-tighten all fittings to avoid damaging the cooling unit. Depending on the individual system, placing the cooling unit 3-6 feet (1-2 meters) away is an acceptable distance for most installations.
Connecting the Slot Adapter Installing the Slot Adapter The included Slot Adapter allows the cooling system to connect with ATX computers through an available card slot. It is responsible for inlet/outlet tubes, the external power cable, temperature sensors, and shutdown lead. Install the Slot Adapter into any available rear card slot in your computer.
Power Connection ATX Pass-Through Lead The cooling system requires 12V DC up to approximately 20W. Since it’s adapted internally, it does not use a separate AC outlet when powered by a computer. (See AC power option later.) The ATX pass-through lead is responsible for sending the shutdown signal if any sensor reaches 3ºC (5ºF) above the preset alarm temperature (See LED Display for configuration). Connect the Slot Adapter’s main power plug to a computer power supply 4-pin Molex plug.
AC Power Option Cooler & Tubing Configuration To power the cooling unit with 110VAC/60Hz or 220VAC/50Hz, an optional power inverter is available from Koolance. This connects to the cooling system’s rear 9-pin plug. There are a vast number of methods for configuring hoses in a liquid cooling system (serial, parallel, combinations, alternating components, etc.).
Parallel Loops Disconnecting Hoses Parallel loops are normally used to help accommodate water blocks with significantly disproportionate flow restriction. They can become quite complicated, and if not well-planned, may lower performance through added bottlenecks and pressure drop. One suggestion for parallel loops is to reduce tubing size when splitting. Ideally, the hose area going into the splitter will be roughly equal to (or slightly lower than) the combined hose area coming out.
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. With the connected outlet hose, roughly estimate the length you will need to your first cooler, and cut it. Cut the second hose with enough length to reach the last water block that will be in your system.
Testing & Filling Replace the fill port on the reservoir. Do not overtighten the fill port. Once all the water blocks have been connected, the system can be filled with coolant. The fill port is located on top of the reservoir. Remove the large slot-headed screw (with a screwdriver or large coin). ! The cooling system should be powered on to assist in the filling process. This also allows you to check hose connections and make sure there are no tubing folds, leaks, or blockages.
Adding Coolers & Maintenance Troubleshooting With normal use, Koolance’s liquid coolant should be replaced every 2-3 years. If it ever becomes contaminated, unclear, or significantly changes color, it should be replaced immediately. A Koolance “drain valve” (sold separately) is recommended to make that process easier. We hope your Koolance system will provide you with years of reliable cooling performance.
this procedure may not be possible since there will be no visible air gap. 5. My system has boot-up problems, or does not turn on... 5 - 5 (“S - S”): Sensor short. This indicates that the sensor may be faulty or electrically bypassed. If the sensor is listed with an “S-S” status, the cooling system alarm will sound. The sensor should be replaced. Please visit our support web page. The majority of these problems are not related to the Koolance system, but to hardware or configuration issues.
Limited Warranty Koolance Incorporated (“Koolance”) warrants each new Koolance liquid-cooled system (“the system”), against defects in materials or workmanship for a period of one year from the date of purchase, and agrees to repair or replace any defective Koolance system without charge. Shipping costs are non-refundable. This warranty is non-transferable. All warranty claims must be accompanied by the original proof of purchase.
