Warning: To reduce the risk of fire or electrical shock, do not expose this equipment to rain or moisture. The Fan System is factory-set for 110V, 120V or 230V AC operation at either 50 or 60 Hz, according to the country for which the unit was manufactured (230V in European Union countries, in compliance with CE regulations). The operating voltage cannot be changed by the user and any attempt to do so will void the warranty. There are no user serviceable parts inside.

Once the RP-850 has completed its test, it is recommended that the switch be placed in its `auto' position. [. . . ] Behind the grille front is a removable air-filter pad.
