This product is intended for installation only by expert users. Please 
consult with a qualified technician for installation. Improper installation 
may result in damage to your equipment. EK Water Blocks assumes no 
liability whatsoever, expressed or implied, for the use of these products 
nor their installation. The following instructions are subject to change 
without notice. Please visit our website   www.ekwb.com for updates. 
Before installing this product, please read the important notice, 
disclosure, and warranty conditions printed on the back of the box.

Before you start using this product, please follow these basic guidelines:

Please read the manual carefully before starting the 
installation process.

Please remove your graphics card from the computer 
to ensure the safest mounting process and prevent any 
possible damage to your GPU and/or graphics card circuit 
board (PCB).

The EK-HFB and EK-ACF type fittings require only a small 
amount of force to screw them firmly in place since the 
rubber O-ring gaskets ensure the liquid seal.

The use of corrosion inhibiting coolants is always 
recommended for any liquid cooling system.

Do not use pure distilled water. For best results, EK 
recommends the use of EK-CryoFuel coolants.

Make sure to bleed the air from your water block thoroughly, 
or you will not reach optimal performance.
