7 P REPARING THE COOLANT
Your kit comes with a 2 Oz (60ml) bottle of Swiftech’s specially formulated HydrX  concentrated coolant. The product
should be mixed with distilled water only. Simply empty the concentrated coolant into a 33 fl oz (1 liter) plastic bottle, and
complete filling with distilled water. Your coolant is now ready. Note: a 5% mix might still allow some algae formation
over prolonged usage if your system is continuously exposed to daylight (such as a clear acrylic case for example).
Under such circumstances, we would suggest using a 10% mix (1 bottle for ½ liter)
Use of alcohols (Alcohol Allyl, Amyl, Benzyl, Ethyl (Ethanol), Isopropyl, Methyl (Methanol), n-Butyl) or antifreeze
products containing the listed alcohols is prohibited as it will result in deterioration of the reservoir over-time,
and will void your warranty. Resistance to Ethylene and Methylene glycol used in antifreeze products is excellent.
8 F ILLING - UP THE CIRCUIT
Simply pour the coolant that you prepared into the reservoir – carefully to avoid spills, allowing the circuit to fill-up by
simple gravity. Note: for the gravity to take effect the reservoir should be placed or held at the highest point of the cooling
circuit. Once the reservoir is full, seal the fill port back with its cap in order to avoid any spills, and start-up the pump
(see Note in chapter 9 below on how to startup the pump). The reservoir will quickly (within 1 second) empty itself.
Immediately turn off the pump, top-off the fluid to the maximum level, and restart the pump. You need to repeat this
operation 2 to 3 times, until the circuit is finally full of coolant. Then, allow the system to run 10 minutes uninterrupted to
clear all the micro-bubbles and foam, and finally top-off the level one last time. Your liquid cooling circuit is now ready.
Allow the system to run for (3) hours and frequently inspect all your connections for possible leaks before you
reconnect and re-install all your components (motherboard, hard drives, etc.)
The Minimum Operating Level is situated at the Swiftech Logo (approximately ½” of the reservoir). The reservoir
should not be operated below this level, which could result in degradation of the system cooling.
9 N OTES AND TROUBLESHOOTING
While filling up the reservoir, the pump discharge tube does not fill-up with fluid: this will prevent the pump from
priming and circulate the liquid thru the circuit. It means that there is a significant pocket of air trapped in the circuit,
preventing the fluid to rise up to the pump discharge spigot. Make sure that your reservoir inlet and outlet barbs are
oriented upwards. If your installation required that the reservoir be mounted upside-down, temporarily dismount it from
the chassis, this will allow the air to escape and travel up to the reservoir. If you are using Swiftech’s “Radbox” simply
remove the 4 screws from the half shell and rotate the reservoir until the filling procedure is complete, then re-attach the
radiator/fan/half shell assembly to the Radbox base.
Air keeps circulating into the circuit, long after the pump has primed:
There is a significant pocket of air trapped into the circuit, check the radiator as indicated above, and/or the water-block.
The fluid level is too low: top-off the reservoir to the appropriate level.
One of the components connections is loose, or improperly tightened: Inspect each connection for traces of moisture,
and tighten all worm-drive clamps, and various connections in the circuit.
Note - Starting the Power Supply when the motherboard is not connected
While the Internet contains numerous references on how to use a paper-clip to short-out pin 13 (GND - BLACK) and 14
(PS-ON – GREEN) of the 20 pin ATX connector as shown below, we nonetheless recommend instead using a power-
supply tester. A wide variety of these common devices are available on the Internet (Google key word: “PSU tester”),
and among Swiftech resellers (www.frozencpu.com, www.Directron.com, www.newegg.com, etc.).
