Bio‑Rad Laboratories warrants the power module, chamber, variable‑speed pump, and accessories for one year against defects in materials and workmanship, with repair or replacement free of charge.
Opening the lid breaks the low‑voltage current path, causing the power module to shut off the high‑voltage supply, preventing shock.
A PC with an 80386 processor or compatible running Microsoft Windows 3.1 is required for the interactive algorithm.
