Operation & maintenance notes

Topic	Recommendation
Water quality	Use distilled or demineralized water to avoid scaling.
Loading	Do not overload baskets; ensure steam circulation.
Program selection	Choose the correct program for load type (solid, liquid, waste).
Exhaust speed	For liquids, always use slow exhaust to prevent boiling over.
Cleaning	Regularly clean chamber and water tank; drain after use.
Calibration	Periodically check temperature/pressure sensors; accredited service available.
