5.Mount case horizontally over wires directly to wall using 2 long screws provided.

6.Replace faceplate and knob.

Step 2ÐDuct Mounting (Low Voltage)

1.Locate humidistat at least 8 in. upstream of humidifier in return-air duct. If mounting near elbow area, keep device 6 in. upstream of elbow so element will be affected by normal airflow. (See Fig. 20.)

2.Remove protective backing from template furnished with each control and apply self-adhesive side on return air duct at selected location. Following instructions on template and in Fig. 21, drill 2 mounting holes and six 1/4-in. diameter sensing holes in duct. Sensing holes allow return air to reach nylon sensing element and operate humidistat.

NOTE: If desired, cut square hole in duct as indicated on template as an alternative to holes.

3.Remove protective backing from foam gasket provided with control and apply to template.

4.Run low-voltage wire from humidifier to template. Lay wire over 1 side of foam gasket. Wire can enter humidistat case from any direction.

IMPORTANT: Do not position wire directly under standoff pro- jections at back of case. If wire is under these projections, case will not seat tightly against gasket causing air leakage and possible improper operation.

5.Remove knob, faceplate, and switch assembly from case by following steps listed below.

a.Remove knob by pulling away from casing. (See Fig. 18.)

b.Lift off faceplate, starting at right side. Left end of faceplate protrudes under lip on casing. (See Fig. 18.)

c.Remove switch by removing 2 screws in back of casing. Pressing tab on case. Lift out control. (See Fig. 19.)

6.Make connections to screw terminals on switch assembly. Re-install switch into casing Ð secure with 2 short screws.

7.While holding wire in place. Mount humidistat case horizon- tally on duct using 2 mounting screws provided. Tighten firmly so that gasket seals space around wires and between case and duct. (See Fig. 21.)

8.Replace faceplate and knob.

Step 3ÐWiring

All wiring must comply with local codes and ordinances.

Step 4ÐAdjustment

Recommended humidistat setting should only be used as a guide. After adjustment of setting, allow at least 5 hr for equilibrium to be reached. Condensation on single pane windows or woodwork indicates excessive moisture. Condensation must not be allowed to continue for extended periods of time, or moisture damage can result. Lower humidistat setting in small steps until condensation disappears. However, if air is too dry, raise the setting.
