INSTALLATION
Caution
1. Before refilling coolant for testing the water cooling system, please make sure
again that all water tubes and connectors are securely fitted and correctively
positioned. (EK-EKoolant high quality coolant is recommend)
2. If any fault develops not caused by pump but caused by falsely installation, the
damage is not covered by the two (2) year warranty.
3. Please notice that if the water tube is folded to cause the water flow stopped
while installation.
4. Forbid to operate EK pump without liquid.
5. Operating environment: Indoor or in the computer case, environment
temperature range is 0 ~ 60oC.
6. While removing water tubes, be sure to keep the device of these tubes away
from any electronic part.
7. If you hear noise of bubbles while pump is operating, please make sure that the
air pocket is out of the pump. (to see details in Annotation below)

Step 1 Placing the water tank / reservoir
1. Make sure the water tank / Reservoir is placed above the pump.
2. This enables water coolant to fill the pump and enables pump to fill the
whole system with water.
Step 2 Installation of connector
3. Setting the O-ring on the G1/4 threaded fittings.
4. Fitting the connectors with water outlet and inlet of pump tightly.
(The pump suits with G1/4 threaded fittings.)
Step 3 Installation of water tube
1. Setting the clamp on the tube first.
2. Tightly link the tube with connectors which connected with pump.
3. Using the clamp to clamp the junctions.
(Please make sure that every junction is tightly connected.)

Step 4 Installation of power supply
1. The power cord of pump can be plugged into CPU fan’s power outlet on
motherboard. Besides, you can use 3pin turn 4pin cord to connect with
power supply in the non-use of sensor line situation.
2. Please read motherboard or power supply manual in detail before pump
installation.
3. If you choose to use AC adaptor for power supply, please select DC12V,
1A to 3A ones. (Please make a choice depending on product
specifications)
Step 5 Infusing coolant
1. Before you infuse coolant, please make sure that the water-cooling
system has been full assembled.
2. When you fill the coolant into the water tank/reservoir, please move pump
and water tank out of the housing to prevent other components from
improper infusing damage. Or cover other hardware with thick layer of
paper towels or regular towels.
3. Open the refilling lid of water tank, and fill the coolant almost to the top of
the water tank/reservoir then cover the top of the tank/reservoir back.
4. Turn on the power for few seconds only, and check the coolant is sucked
into the system. Before the water tank/reservoir is empty turn off the
pump.
5. According to different watercooling systems as they can accept different
volume of coolant, such as tank capacity and tube length, you may need
to repeat the step 4-1 and 4-2 to make sure coolant is full of the whole
system.

Step 6 Fixing pump
1. After confirming no leakage situation, you can start fixing pump.
2. There are four equidistant holes on both top and bottom sides for two
steadies. You can freely choose which direction you want to fix. Besides,
you can add pad to strengthen the shock-absorbing effect.
3. After selecting the fixed mode that you like, assemble mountings, then fix
in the place that you make selection.
Annotation: Exhausting / Bleeding
Placing tank upon pump, turn on the power for 1 minute then turn off the
power for 1 minute, too. This action should last 5 minutes.
This will help bleeding the small air bubbles from your watercooling system.
