a few minutes of your time is required to read this manual for a properly wired
installation and becoming familiar with its features and how to use them. Please

radiator, in front of heating vents, to direct sun light, in excessive humid or dusty
location to avoid damages and to guar- anty a long reliable use. Connect your unit
