Bitmain's guide puts pH at the centre of routine checks and says coolant below pH 7 should not be used. Test pH roughly every six months, track freezing point and conductivity, and do a full coolant check at least once a year. When draining for repair, empty the miner completely.

Bitmain's standard warranty for new S19 and later miners is 365 days from the official shipment date, subject to the sales contract, and is tied to the serial number. A used unit keeps whatever is left of that period. Check the serial on Bitmain's warranty check page before buying. Out of warranty units can still be repaired for a fee.

Bitmain designs it to run with its own hydro cooling infrastructure, but what the miner needs is the flow, pressure, temperature and fluid quality in its spec. A home loop with a pump, dry cooler and plate heat exchanger can meet that if sized for over 5 kW of heat per unit, plus three phase power. Most owners use a hosting site.

Bitmain lists 8 to 10 litres per minute per unit, pressure up to 3.5 bar, inlet coolant 20 to 50°C, and OD10 pipe connectors. Approved fluids are antifreeze (pH 7.0 to 9.0), pure water (6.5 to 7.5) or deionized water (8.5 to 9.5). Use a glycol mix rated for the lowest temperature on site, since frozen and cracked heat exchangers are not covered.

No. Bitmain specifies three phase 380 to 415 V, 50 or 60 Hz, up to 12 A per phase, through an APW11 power supply with a waterproof connector. The power cord is not included. Bitmain also requires an earthed supply, a surge protection device and a disconnect that cuts all three phases at once. Plan the electrical work with a qualified electrician.

They are the same machine in different bins. Bitmain lists 279 TH/s at about 5,301 W and 293 TH/s at about 5,567 W, both around 19 J/TH at 35°C coolant inlet. The 293T makes more hashrate and needs more power and cooling capacity per unit. Compare both in the calculator at your power price.
