INSTALLATION
The control may be mounted in any location provided that
the temperature and humidity of the air in which it is
located will not cause a condensation on the switch parts.
If the ventilating equipment manufacturer has made pro-
visions for, or recommendations for location of this con-
trol, then follow those instructions. If not, the following
suggestions should be observed.
1. The control should be mounted approximately six feet
from the floor, as near as possible to the center of the
ventilated area.
2. Do not locate control on or near an outside wall.
3. Wherever possible, mount on a partitioning wall or on
a post.
WIRING
All wiring should be done in accordance with local and national electrical codes and ordinances.
If the manufacturer of the cooling equipment has supplied
a wiring diagram, follow such recommendations. The
following diagrams show the general use of these con-
trols.
