READ AND SAVE THESE INSTRUCTIONS
TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR INJURY TO PERSONS,
OBSERVE THE FOLLOWING:
1. Use this unit only in the manner intended by the manufacturer.
If you have questions, contact the manufacturer at the address or
telephone number listed in the warranty.
2. Before servicing or cleaning unit, switch power off at service panel
and lock the service disconnecting means to prevent power from
being switched on accidentally. When the service disconnecting
means cannot be locked, securely fasten a prominent warning
device, such as a tag, to the service panel.
3. Installation work and electrical wiring must be done by a qualified
person(s) in accordance with all applicable codes and standards,
including fire-rated construction codes and standards.
4. Sufficient air is needed for proper combustion and exhausting
of gases through the flue (chimney) of fuel burning equipment
to prevent backdrafting. Follow the heating equipment
manufacturer’s guideline and safety standards such as those
published by the National Fire Protection Association (NFPA),
and the American Society for Heating, Refrigeration and Air
Conditioning Engineers (ASHRAE), and the local code authorities.
5. When cutting or drilling into wall or ceiling, do not damage
electrical wiring and other hidden utilities.
6. This unit must be grounded.
7. Do not connect this product as a load on a fan speed control or
light dimmer.
8. Read and understand entire instructions before proceeding with
installation.
INSTALLATION
Install controls and wire them as shown. Use following guidelines:
• IMPORTANT:

control.
QTXE110 Ultra Silent™ fan must be wired to SMSC110
SmartSense

control.
• Useminimum75°Cratedelectricalwiring.
• Except for required neutral wire, these controls install like
normal switches. Make sure electrician knows each control
location must have a neutral wire. Neutral wire at switch
locations may be code requirement or regular practice in
installation municipality; but unless explicitly specified,
electrician might not install it.
• Specify deep device electrical boxes where controls will be
installed. These controls fit in most North American electrical
boxes; however, deep boxes provide extra working space which
eases installation. Labor cost savings can offset higher box
costs, which is usually less than a dollar over standard depth
boxes. Use boxes that have 18 cu. in. minimum volume and
are at least 1-1/2 in. deep.
