Wall Mounting
IMPORTANT:
• Mount the humidity controller in an area with
average room temperature and average
relative humidity. The maximum temperature
at the location selected must not exceed
125 ° F (52 ° C).
• The humidity controller can be mounted
directly on the wall.
Locate the humidity controller about 5 ft (1.5m)
above the floor on an inside wall.
Drill a small hole in the wall.
Run low voltage wiring to the location and pull about
6 in. (152 mm) of wire through the hole.
Plug the hole with nonflammable insulation to prevent
drafts from affecting the humidity controller operation.
Remove the humidity controller assembly by
inserting a screwdriver into the notch on the bottom
of the case and prying loose.
Position the case horizontally over the wires with the
arrows on the tabs pointing up and secure the case
to the wall using the two screws provided.
Connect the wires to the humidity controller assem-
bly using leadwires and wire nuts provided (see
Wiring section and Fig. 2).
Tuck the wires into the bottom of the case.
Snap the cover assembly into the case (Fig. 2).
