Filling & bleeding the circuit
We recommend using the following mix: 95% purified
water, and 5% of one of the following products:
Swiftech’s specially formulated HydrX coolant,
RedLine water wetter, or Zerex Racing Coolant.
In order to fill and bleed the circuit, you will need to activate
the pump. Since you do not want to run the computer until the
cooling circuit is completely operational, you should
temporarily connect the L wire to the N\C position of the
switch. WARNING: do not forget to reconnect to N\O once
you are ready to run the computer: if you leave the L wire
connected to N\ C, the pump will shut off as soon as the
relay is energized by the power supply, and there would
be no flow in the cooling circuit, causing your CPU to
overheat.
1. Place a holding tank containing your cooling fluid
above the computer.
2. Connect the ¼” tube provided with your kit. Tube 1
goes to valve 1 and tube 2 goes to valve 3
3. Plunge tube 1 only into the holding tank, making sure
it is entirely submerged
4. Open valve1, close valve 2, open valve 3
5. Prime the circuit by gently sucking in air from tube 2,
just enough that you see the liquid starting to flow
down in tube 1
6. Now, you can plunge tube 2 back into the holding
tank
7. Start the pump
8. Let the pump run for 1 minute as shown in the picture
to the right. The liquid should be flowing freely from
tube 2 into the holding tank.
9. Important step: after a minute, and while the
pump is still running:
• Take the holding tank and tubes into one hand –
making sure that the tubes remain plunged into
the liquid,
• Then lay the computer down for just a few seconds
once flat on it’s back, and once flat on its belly. This
will bleed any air still trapped into the circuit.
