• Power Supply: Single phase AC 110-120/220-240 V, 50/60 Hz, ~2.1 kVA with protective ground (3P type). Voltage details on machine identification plate.
• Water Supply: Pressure 69-300 kPa at flow rate >1000 mL/min; temperature 5 to 30°C.
• Dialysate: Concentration 130-159 mmol/L; bicarbonate 20-35 mmol/L; sodium 130-180 mmol/L; flow rate 300-600 mL/min; temperature 34-39°C.
• Blood Pump: Closed loop circuit with ultrafiltration (UF) pump; UF rate 0 to 5.00 L/h; UF profile 0 to 150%; accuracy ±30 mL/h; flow rate 0.50 to 600 mL/min (using 8.5 or 12 mm tubes) or 0.30 to 360 mL/min (using 6.4 or 9.6 mm tubes); accuracy ±20 mL/h.
