III. Fill and bleed operations
LEAK PROOF YOUR CIRCUIT BEFORE YOU FILL IT UP – DO NOT SKIP THIS STEP!
The following procedure is a convenient and safe solution to leak proof your circuit WITH ALL THE
COMPONENTS ALREADY INSTALLED
,
BUT WITH
NO
LIQUID IN THE SYSTEM , thus avoiding any chances of
spilling moisture on your valuable components, thanks to Swiftech’s fill-and-bleed system:
Close the main valve as shown in Figure 7.
CRITICAL
TIP!
Connect the 2 precut tubes that came with your kit to the inlet and discharge valves of the fill & bleed kit.
Open either one of the inlet or discharge valves, and close the other.
Suck vigorously on the open line to create a vacuum inside the circuit (see note*).
Close the valve. You now have a circuit under moderate vacuum.
Remove the tube from your mouth, and wait 30 seconds to a minute.
Finally, obstruct the extremity of the tube with your thumb, and re-open the valve. Tube should adhere to your thumb
as a result of the vacuum. This is evidence that your system is completely air tight, thus completely leak proofed ☺
* Note:
The tubing we use is food grade, and as long as you clean it properly, it can be safely placed into your
mouth.
Fill and bleed operations, step by step
1. Preparing 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 or demineralized water only. Simply empty the
concentrated coolant into a 33 fl oz (1 liter) plastic bottle, and complete
filling with your distilled water. Your coolant is ready.
2. Connecting the fill-and-bleed tubes
Connect the 2 precut tubes that came with your kit to inlet and
discharge valves of the fill & bleed kit, and set the valves as shown
Figure 7. The extremity of the inlet tube should be pushed all the way
down the bottom of the feed bottle.
Note the orientation of the valve levers in Figure 7.
Since the valves close clockwise, positioning the
valves as shown here will orient the valve levers
towards each other once closed, which is easier to
reach if your case does not feature a removable
top (see closed valve position Fig 12 page 8)
3. Priming the circuit
WARNING: DO NOT SKIP THIS STEP UNDER ANY
CIRCUMSTANCE – Your pump is not self-priming, and the pump
impeller housing must be filled with fluid before you apply power.
HOLD THE FEED BOTTLE ABOVE THE COMPUTER,
and start gently sucking on the discharge tube to prime the circuit.
Then place it back into the bottle. The coolant will start flowing down
the inlet, and the circuit will fill-up by simple gravity (figures 8 and 9)
