Before you start using this product, please follow these guidelines:
• Please carefully read the complete manual before beginning with the installation process.
• No liability is accepted for installation errors.
• Only use plastic, copper or brass components in the circuit. The use of other materials can lead to
corrosion and other damage to the waterblock.
• Before mounting, please check the compatibility of the cooler with your GPU by comparing the PCB
on page 2 with your GPU.
• All Bykski coolers are approved for use with „Aquacomputer DP-Ultra“ liquid only. The use of other
uids occurs at the user‘s own risk.
• Bykski GPU coolers must only be cleaned with distilled water, the use of other cleaning agents may
damage the cooler! Never use cleaning agents containing alcohol or acid, this causes the destruc-
tion of the acrylic components and may attack the nickel plating!
• Tighten the screws and ttings carefully and rmly. Never use brute force.
• Make sure to thoroughly bleed air out of your water block, otherwise the cooling capacity may be
limited.
