Caution
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. This will 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 the entire cooling system – copper, brass, nickel, aluminum, and steel – from corrosion.
- Fill the reservoir with coolant and cycle the power on and off several times while the pump pushing the coolant into the loop.
- DO NOT let the pump run dry, when there is no liquid entering the pump turn off your power immediately.
- Fill the reservoir to the top as it will prevent air from going into the pump
- If necessary tilt the system slightly from side to side to bleed the air out of the loop.
- Place some paper towels under fittings and joining points to test for leaks.
- Run the loop with the fill port open for about 24 hours to completely bleed the air out of the loop.
- Before starting, flush out your system correctly to prevent any coolant or unwanted particles sticking to your tubes, radiators and other cooling components.
- Coolant might fade over time.
