1 Chapter Introduction User Manual 1
Congratulations on your purchase of a Koolance system! As the most sophisticated product of its kind, Koolance offers many unique features found nowhere else in the realm of computer cooling. In addition, you can expect to enjoy all of the advantages that water-cooling technology brings with it. Advantages of Water Cooling Water transfers 30 times faster, and holds over 4 times more heat than air.
Every Koolance system includes built-in hardware safety features. Our proprietary power control board constantly monitors liquid temperature, sounding an alarm if it should get too high, and even turning-off your computer if you are not there to do so. But Koolance’s innovations extend beyond just cooling features. Our safe, patent-pending CPU Retention Clip places even pressure across the CPU, protecting the chip and simplifying installation.

Radiator - The primary heat exchanger is the main cooling element, and provides high thermal dissipation in a relatively small area.
System Settings By default, the ERM-3K4U automatically adjusts fan speeds based on the liquid temperature inside the reservoir. For actual CPU temperatures, please refer to your motherboard’s BIOS, or 3rd-party software. The Koolance system alarm will sound if the reservoir sensor gets too high (default: 55ºC / 131ºF). While alarming, the radiator fans will increase to 100% power. This temperature is adjustable (See “LED Display - Alarm Settings”).
Details on fan modes are as follows: Auto Mode Manual Mode Fan Power % Total CFM Fan RPM 0 - 35ºC (32 - 95ºF) 1 30 84 720 36 - 37ºC (97 - 99ºF) 2 35 99 840 38 - 39ºC (100 - 102ºF) 3 40 114 960 40 - 41ºC (104 - 106ºF) 4 45 129 1080 42 - 43ºC (108 - 109ºF) 5 50 141 1200 44 - 45ºC (111 - 113ºF) 6 60 171 1440 46 - 47ºC (115 - 117ºF) 7 70 198 1680 48 - 49ºC (118 - 120ºF) 8 80 225 1920 50 - 51ºC (122 - 124ºF) 9 90 255 2160 52 - 99ºC (126 - 210ºF) 10 100 282 24
LED Display - Rotating The front LED display of the ERM-3K4U can be rotated horizontally and used as a 4U rackmounted chassis, or vertically and used as an upright tower. By default, the display is in the horizontal position. Top Cover To rotate the display, remove the ERM-3K4U top cover (above the reservoir), both rack handles and ears, and both front bezel side screws.

Power Connection The ERM-3K4U has a primary power connection on the rear side. This will accept either 120V/60Hz or 220V/50Hz inputs. The main AC power switch will be illuminated whenever power is supplied to the ERM-3K4U unit, whether the switch is “ON” or “OFF”. The “ON” position is indicated with an arrow: ◄. Pump Connections Pump 1 Pump 2 Pump 3 Pump 4 Pump 5 (Number of pumps present varies by model.
Cooler & Tubing Configuration 3/8” (10mm) or 1/4” (6mm) ID Rear quick disconnect nozzles for 3/8” (10mm) internal diameter tubing are included with the ERM-3K4U. If desired, these pump inlets and outlets can be converted directly to 1/4” (6mm) ID lines using optional Koolance quick disconnect nozzles. For 1U profile computers, 1/4” (6mm) ID is recommended.
Parallel Tubing Koolance coolers which are 6mm (1/4”) can still be effectively used in larger diameter systems. Using a parallel tubing configuration with hose splitters will help maintain coolant flow rate through these systems.
Connecting Hoses Each tubing connection uses a threaded compression fitting (“hose screw”) to keep it secure. To connect these components: Thread a hose screw onto the tube end. Squeeze the tube while pushing it firmly over the nozzle. Tubing should completely cover the nozzle. Tighten the connection by sliding the compression fitting down over the nozzle and screwing it securely by hand. Do not overtighten the nozzle fitting.
Disconnecting Hoses Hoses are designed to snug firmly around the nozzle. If you need to remove a hose for any reason, it may not pull off easily, even after unscrewing the compression fitting. Usually, a connection will come free by squeezing the hose on top of the nozzle and pulling away. Pulling in front of the nozzle will stretch the tubing and make it tighter. If this fails, cutting a small incision lengthwise (parallel) along the nozzle will free it.
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. Generally, the outlet of the cooling system or radiator will connect with your CPU Cooler, but this is completely optional. With one of the connected hoses, roughly estimate the length you will need to your first cooler, and cut it.
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 kits’ individual installation instructions, then continue on to the next section.
3 Chapter Filling & Maintenance ! 16 WARNING: The ERM-3K4U pumps can not be run “dry” for any period of time. Never power-on the cooling system without sufficient liquid in the reservoir. Dry-running (and thereby damaging the pump) is not covered under the Koolance product warranty.
Testing & Filling Once all of the coolers have been connected, the system can be filled with coolant. The refill plug is located on top of the reservoir bay unit. Unscrew the small metal refill plug by hand. If it is too tight, use pliers to loosen it gently. To avoid damaging the tank threading, never use tools to tighten the metal refill plug when screwing it back in. ! WARNING: The liquid coolant is electrically conductive.
Allow the pump to run for about 1-5 minutes. When filtration has ended, the liquid “bubbling” noise should stop. The reservoir level will typically drop during this bleeding process. Add more coolant and repeat as necessary until the reservoir level stabilizes. (In the future, if you begin to hear air bubbles rushing through the pump, it may indicate that more coolant needs to be added.) Pump Cavitation The ERM-3K4U pumps can be sensitive to cavitation during the initial bleeding process.
Adding Coolers & Maintenance For preventative maintenance, Koolance recommends replacing the liquid coolant every 2 years. A Koolance “drain valve” (sold separately) can make that process easier. The liquid should be immediately replaced if it ever becomes contaminated, unclear, or significantly changes color. Although uncommon, biological growth and corrosion are substantially easier to prevent than clean-up.
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. The pumps do not appear to be operating properly... The pumps need to be “burped” during the initial bleeding process to avoid this situation. Reduce pump speed using the rear dial (but not low enough to stop the pumps).
be malfunctioning. Please visit our support web page for more information. Verify that the pump is operating (see Troubleshooting #1), and that liquid flow is present in the reservoir. Note that if the reservoir was over-filled during system assembly, this procedure is not possible since there will be no visible air gap. 5. My system has boot-up problems, or does not turn on... The majority of these problems are not related to the Koolance case, but hardware or configuration issues.
8. The LED Display Panel shows 5 - 0 (“S - 0”) or 5 - 5 (“S - S”)... Your Koolance LED display may specify if there is a problem with the cooling unit. Please use the following guide in determining the cause of a problem: 5 - 0 : Sensor open. This indicates that the temperature sensor may be disconnected or faulty. If the sensor can not be detected, the cooling system alarm will sound. The sensor will need to be reconnected inside the unit, or else replaced.
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.
