※The unit is coated with ABS (control panel), polyphenylene ether (bath cover), polyacetal (nozzle and drain plug)
and nitrile rubber (tray). (These are nonferrous materials). Compared to metals, these plastics and rubbers can
be easily discolored, deformed and damaged by heat, light (example: direct sun), solution (example: circulation
liquid, cleanser) and forces (impact). So use caution when handling the unit.
