• Do not mount directly on exterior walls below grade (condensation)
• Protect from plumbing leaks
• Protect from splash caused by sprinkler system inspection ports
• Do not mount in areas with humidity-generating equipment (such as dryers, production machinery)
When selecting a location to mount the 6820 control panel, the unit should be mounted where it will NOT be exposed to: temperatures out-
side the range of 0°C- 49°C (32°F-120°F) or humidity exceeding 93% non-condensing.
