HVAC Products 30 May 2008
General notes
The RMS705 switching and monitoring device is maintenance-free (no battery chan-
ges, no fuses). The unit should only be cleaned with a dry cloth.
The unit cannot be repaired on site.
The RMS705 switching and monitoring device is subject to 2002/96/EEC regulations
(WEEE, Waste of Electrical and Electronic Equipment).
"The device must be disposed of as electronic scrap in compliance with the European
directive 2002/96/EEC (WEEE) and not together with municipal waste. The relevant
national regulations must be observed using the correct disposal channels. Local and
currently valid legislation must be complied with."
