General installation guidelines

It is recommended to install the unit in a hallway to limit the MVS-1C exposure to
-
noxious gases.
In order to avoid condensation problems inside the MVS-1C, it is recommended to
-
install the module on an inside wall. If it is not possible, use spacers to have an air
gap between the wall and the controller.
The MVS-1C should be installed in easy-access location but away from damaging
-
elements (heat, cold, water, direct sunlight...).
Do not install the MVS-1C near high-voltage equipment, power supply or
-
transformer.
When installing the mounting plates onto the back of the enclosure, makes sure to
-
use a regular screw driver (DO NOT use a drill or electric screw driver) to screw the
tap screws into the plastic holes.
