INSTALLATION

Caution:

• Installer must be a qualified, experienced technician

• Disconnect power before installation to prevent electrical

shock and equipment damage.

• Make all connections in accordance with electrical wiring

diagram and in accordance with national and local electrical codes. Use copper conductors only.

• NEMA Type 1 covers are intended for indoor use primarily to

provide a degree of protection against contact with the enclosed components.

MOUNTING PROCEDURE

Mount the HC-201 on the outside surface of the return air duct in a horizontal position where it is exposed to freely circulating air (other mounting positions are possible but not preferred).

Caution: Avoid locations where excessive moisture, corrosive fumes, vibration or high ambient temperatures are present.

See Figure 3 for template dimensions for mounting.

1. Remove adhesive from the back of mounting template and press template to desired mounting location on duct.

2. Drill the four mounting holes as indicated on template, using No. 30, 1/8-inch (3 mm) diameter drill.

3. Cut out center portion of duct as outlined on template.

4. Using four (4) of the provided mounting screws, mount humidistat to the duct.

5. Remove the cover and make all electrical connections in accordance with job wiring diagram and in compliance with national and local electrical codes.

6. Replace the cover and install cover screw provided.

7. Turn dial knob to desired setting. If locked dial setting is desired, remove dial knob, tighten the dial lock screw and replace knob.
