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.

Install controls and wire them as shown. Use following guidelines:

•IMPORTANT:

QTXE080 Ultra Silent™ fan must be wired to SMSC080 SmartSense® control.

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

•Use minimum 75 °C rated electrical wiring.

•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.

•All controls must be grounded using attached ground wire.
