Warnings from the manual
We have not found manual warnings for this model.
Notes
The page gives the frequency as 38–41 kHz (no single value, so left empty). 30 W is given in the voltage row and is probably total power. Max water level 600 ml. Tank measures (oval ends) from the seller's reply in the questions and answers. Presets 90/180/280/380/480 s. The page shows the 110 V version (USA); a heater is not mentioned. Verified 2026-10-30
