position. The bracket must be rotated 180 degrees to fit it on the right-hand
side.
● The small mounting bracket must be mounted on the left-hand side if it is being
installed in a station inside the Comfort housing.
● The large mounting bracket is intended for installation in a station inside a
Large housing – where it has to be mounted on the right behind the power
supply – or for installation in a 19" pedestal housing – where it can be mounted
on the right- or left-hand side wall.
