EKWB Loop VTX PWM Motor

Product Usage Instructions

Pump Installation:

Insert the O-Ring into a Pump groove.
Install the EK-VTX Pump using four (4) M4x35 ISO 7984 screws. Position the pump onto the reservoir. Make sure all the holes are aligned. Tighten the screws evenly.

Connecting the PumpThe EK-VTX Pump has two connectors: a 4-PIN MOLEX CONNECTOR and a 4-PIN PWM FAN CONNECTOR.

Testing the Loop

To ensure successful installation, perform a leak test for 24 hours after filling the loop with coolant.
Connect the pump to a PSU outside of your system and let it run continuously for testing.

Inspect all parts for leaks, fix any issues, and repeat the testing if necessary.
Ensure all hardware is dry before powering on the system to\ prevent damage.

FAQ

Q: Can the EK-VTX Pump be used with all FLT reservoirs?
A: Yes, EK-VTX pumps can be used with all FLT reservoirs compatible with DDC pumps.

Q: What should I do if I encounter coolant leaks during testing?
A: If leaks occur, fix the issue, repeat the testing process, and ensure all hardware is dry before powering on the system.

Q: Where can I find support or order spare parts?
A: For support or spare parts, contact EKWB at https://www.ekwb.com/customer-support

PUMP INSTALLATION

If you have already filled your loop with coolant, you will need to drain it before installing the EK-VTX Pump.

STEP 1
Insert the O-Ring into a Pump groove.
STEP 2
Install the EK-VTX Pump using four (4) M4x35 ISO 7984 screws. Position the pump onto the reservoir. Make sure all the holes are aligned. Tighten the screws evenly. Before attaching the EK-VTX Pump, make sure the O-Ring is placed correctly! Do not use excessive force! For this step you will need:

CONNECTING THE PUMP

The EK-VTX Pump has two connectors:

4-Pin Molex – must be connected directly to your PSU at all times as it is used to power the pump;
4-pin PWM Fan – can be connected to your motherboard CPU Fan or designated water pump header. It can also be connected to a controller. This cable is used to control and report the rotational speed of the pump. If it’s not connected, the pump will run at maximum speed (100% PWM).

TESTING THE LOOP

To make sure the installation of EK components was successful, we recommend you perform a leak test for 24 hours.
When your loop is complete and filled with coolant, connect the pump to a PSU outside of your system. Do not connect the power to any other components!
Turn on the PSU and let the pump run continuously. It is normal for the coolant level to drop during this process as air collects in the reservoir.
Inspect all the parts of the loop, and in the case of coolant leaks, fix the issue and repeat the testing process. Ensure that all hardware is dry before the system is powered on in order to prevent any damage.
