Define the project and site conditions
Start with the proposed number of miners, exact models, operating schedule, expansion plans, and a budget for the complete site. Document electricity availability and tariff structure, outdoor temperature extremes, humidity, dust, water availability, noise constraints, access, and drainage. Confirm locally applicable land-use, building, electrical, fire, environmental, and water requirements with the relevant authorities and qualified professionals. A warehouse with enough floor space is not automatically suitable. Obtain a site assessment before committing to equipment, leases, or installation dates.
Design around the exact equipment
Build a requirements sheet from the current manufacturer manuals for each miner and cooling system. Capture electrical phase and voltage, connector requirements, coolant specification, permitted inlet temperature, flow, pressure, equipment clearances, and operating limits. Similar ANTMINER names can represent different installation requirements. Assign electrical and mechanical engineers to reconcile these documents into one design, including drawings, protective controls, isolation points, and service access. Do not copy limits from another model or use a profitability listing as an installation specification.
Plan a complete route for heat
A hydro miner normally passes approved coolant through internal channels or cold plates in a circulating loop; it is not an immersion tank. The heated liquid must transfer energy to a suitable external heat-rejection system before returning. Have the designer size pumps, distribution, filtration, expansion provisions, heat exchangers, and outdoor coolers for the complete load and local weather. A closed miner loop does not necessarily mean the whole facility consumes no water: an external evaporative system may need replenishment. Include condensation and freeze protection.
Engineer power, controls, and communications
Have a qualified local electrical team design and install the supply, distribution, earthing, cable protection, isolation, and emergency arrangements. Include the auxiliary demand of pumps, controls, and heat-rejection equipment, plus the required design margin. Mechanical and electrical safety must work together so cooling failures cannot leave miners heating without adequate flow. Plan reliable network connections, restricted administrator access, device naming, and alarms that reach the responsible operator. Live wiring, protection changes, pressure testing, and internal equipment work are professional tasks.
Commission in stages and keep evidence
Agree a written commissioning and acceptance plan with the installers before energizing the farm. Qualified personnel should complete the required electrical and mechanical inspections, coolant preparation, leak checks, sensor checks, and safety-control verification. Start with a small approved group, verify stable flow and temperatures, and compare local miner data with pool-accepted work. Increase load only after the previous stage passes. Record ambient conditions, readings, alarms, and defects. A successful boot is not acceptance; the installation should demonstrate stable operation under the agreed test conditions.
Assign maintenance and compare total cost
Set clear responsibilities for daily monitoring, alarm response, coolant quality, filters, pumps, external coolers, spares, seasonal preparation, and specialist repair. Establish a documented shutdown response for leaks, lost flow, overheating, or electrical concerns; never bypass protection to maintain output. Include installation, cooling electricity, water where relevant, consumables, staffing, downtime, insurance, and end-of-life costs in the budget. Recalculate revenue under changing price and difficulty scenarios. Any heat-reuse income depends on a separate viable customer and engineered arrangement, and mining profitability is never guaranteed.
