A hydro-cooled machine (water-cooled) is not "plugged in" like an air-cooled ASIC. Stability depends as much on the machine as on the water circuit : filling, purging, flow rate, heat exchange, and leak control.

At Happy Mining , we see two clean paths to get started:

• Option A: BITMAIN ANTRACK V1 (integrated hydro cabinet/rack, up to 4 miners)

• Option B: 12 ​​kW watercooling kit (compact “plug-and-play” solution for a simple loop)

1) Choose the right option (simple rule)

You want an “organized / multi-machine” module

➡️ Choose the ANTRACK V1 : it is a cabinet designed to accommodate water-cooled miners and centralize integration.

You want to cool one machine (or small setup) with a simple loop

➡️ Choose the 12 kW water cooling kit : it's a practical basis if you want a quick and controllable start-up, without building a complete "industrial" loop.

2) Option A — Hydro Setup with BITMAIN ANTRACK V1

What you buy (in practice)

The AntRack V1 is designed to centralize a clean hydro setup: you install the machines in a “cabinet” chassis, and you rely on an already structured architecture.

Commissioning (reliable method)

1. Placement & access maintenance
   Install the ANTRACK V1 on stable ground, with space to access fittings/valves (this makes all the difference when you need to intervene quickly).

2. Filling + purging (critical point)
   Even with a cabinet, the number one risk remains trapped air . Fill slowly, circulate, bleed, then bleed again. Keep the watercooling manual handy: watercooling_manual.pdf .

3. Progressive assembly of ASICs
   Start with 1 machine, validate the stability (temp/alerts), then increase to 2/3/4. The classic mistake is to fill the cabinet "all at once" without validation.

4. Starting in the correct order
   Always: cooling ON → ASIC ON (otherwise a "dry" start is possible). This point is also mentioned in the watercooling manual. .

✅ When to choose this option: if you want a well-defined “rack/cabinet” setup and a clean deployment path via AntRack V1 .

3) Option B — Hydro Setup with the 12 kW Water Cooling Kit

What is the kit used for (and how to use it correctly)?

The 12 kW water cooling kit is a compact solution for creating a simple loop around one (or a few) Hydro miners, as long as you remain consistent with the thermal load and radiator ventilation.

Commissioning (step-by-step)

1. Placement: Allow the radiator to breathe
   The radiator must dissipate heat through proper airflow. If you place it in a corner, you'll recirculate the hot air and lose all headroom. The basic points are detailed in the watercooling manual. .

2. Pipe connection (supply/return)
   Branch without twisting/pinching, and maintains clean routing. (Yes, it sounds trivial, but a lot of low flow comes from just a poorly positioned hose.) See also the manual .

3. Filling (never start dry)
   The kit states that the coolant is not included : you will need to perform a clean fill and then bleed the system. A dry start is the scenario that causes the most rapid damage. Reference: watercooling_manual.pdf .

4. Purge (often several cycles)
   If the pump cavitates or the flow is unstable, it's often due to air. Re-purge after a few minutes. The manual explicitly mentions cases where air blocks operation: watercooling manual .

5. Startup
   First, the 12 kW water cooling kit in stable circulation → then the ASIC.

✅ When to choose this option: if you want a simple and quick setup around the 12 kW kit , typically for 1 machine (or small, very well-ventilated setup).
