20 21 User Manual Filling & Maintenance
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. Free this component by removing
its side drive screws. Slowly pull it out just enough
to expose the refill plug (about 2.75”, 7cm).
Testing & Filling
WARNING :
Most coolants are electrically conductive. Use caution
when filling the system, and keep all liquids away from electronics and
power cables. In case of emergency during installation, immediately
unplug the primary AC power cable. Dry the system thoroughly before
proceeding.
!
Replace the fill port on the reservoir. Do not overtighten the fill port.
Slowly fill the system. To maintain the product
warranty, use only Koolance approved coolant.
Many alternative liquids and additives can cause
permanent damage to the cooling unit (through
chemical reaction, corrosion, biological growth,
thermal expansion, viscosity, etc.).
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 usually indicates the need for more
coolant.
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 as labeled below (usually green and a
black ground wire; See diagram).
That’s it! Replace the ATX motherboard connection and boot-up the computer.
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).
