Pacific PR2U

Cautions

Thermaltake recommends the following steps to be taken before using the Pacific series radiators and water blocks:

• To ensure a clean loop, flush and rinse your radiators and water blocks with distilled water prior to use.
• Do not use tap water or distilled water as your coolant; it may harm your loop and reduce performance.
• It is strongly recommended to use market-proven pre-mix coolant, such as Thermaltake Coolant 1000. It offers great performance while protecting the entire liquid loop from corrosion.
• Before storing your water cooling components, please clean, rinse, and dry them to ensure a longer lifespan for your components.

Thermaltake recommends the following steps to be taken after completing your water loop setup:

• It is strongly recommended to use market-proven pre-mix coolant, such as Thermaltake Coolant 1000. It offers great performance while preventing corrosion in the entire cooling system – copper, brass, nickel, aluminum, and steel.
• Fill the reservoir with coolant and cycle the power on and off several times while the pump pushes the coolant into the loop.
• DO NOT let the pump run dry; turn off the power immediately if there is no liquid entering the pump.
• Fill the reservoir to the top to prevent air from entering the pump.
• If necessary, tilt the system slightly from side to side to bleed air out of the loop.
• Place some paper towels under fittings and joining points to check for leaks.
• Run the loop with the fill port open for about 24 hours to completely bleed air out of the loop.
• Before starting, flush your system correctly to prevent any coolant or unwanted particles from sticking to your tubes, radiators, and other cooling components.
• Note that coolant might fade over time.
