Koolance EX2-755-R - Manual (Page 14)

20 21 User Manual
If your pump has a speed control option, set it to the lowest level during
this time. Allow the pump to run until the liquid noise subsides.
During this process, cooling systems often need to be tilted gently
to allow air to escape from the pump and radiator. Until the pump
is “burped” in this manner, it can cavitate and there will be no
circulation. (This does NOT indicate a problem with the pump.)
The reservoir level will decrease during this procedure. Remove the fill
port cap and add more liquid when needed. If you frequently hear this
rushing noise in the future, it indicates the need for more coolant.
Replace the fill port on the reservoir. Do not overtighten the fill port.
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. If cooling a computer, this can be done without powering on
other hardware for extra safety (see below).
CAUTION : Jumping the incorrect ATX power supply pins can cause
permanent damage to the power supply.
!
Make sure the AC power cord is attached to the power supply. If the power supply
has a rear switch, it must be set to the ON (-) position. Using the included green
Jumper Wire, insert the metal prongs into the fourth and sixth holes on the 20-24
pin ATX motherboard power supply plug (usually green and a black ground wire;
See diagram
).
That’s it! Replace the ATX motherboard connection and boot-up the computer.
Filling & Maintenance
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.
If you are upgrading or removing a cooling block in your system, please follow the
instructions below.
Adding Coolers & Maintenance
CAUTION : Any time a hose is disconnected with coolant still inside,
leaking will occur. It is highly recommended to empty your cooling
system of coolant before disconnecting any hoses.

Radiator Performance
Over time, dust will accumulate on the radiator. While the cooling system may
continue to operate in this condition, performance can decrease. To keep the
system clean, check the radiator periodically (through the top fan grill) and use
a can of electronics air cleaner if necessary.
Working on a liquid cooling system is much easier and safer when liquid coolant is
removed beforehand. However, certain procedures can be done without removing
the coolant.
A binder clamp (available at office supply stores) is helpful for keeping a hose folded
while removing or adding coolers. Even so, pressure within the cooling system is
such that liquid will not easily flow out unless relieved elsewhere-- for example, by
opening the reservoir fill port.
Bend the hose directly before and after the section to be worked on. Place a binder
clamp on both bends, or tie them in this position to help avoid fluid loss. There will
be some liquid exposed; do not operate on the cooling system in this manner near
or above electronic hardware.
