Lennox CB31MV Air Handler Owner manual

predictable

The CBX32MV has a handle on performance.

The air conditioner or heat pump installed outside your home can’t work alone.

You also need an indoor unit to distribute conditioned air through the ductwork and into each room. The CBX32MV handles that job—and a whole lot more.

We’ve designed the CBX32MV with a variable speed motor

that delivers more consistent temperatures along with enhanced humidity control. It works quietly and efficiently in both heating and cooling modes, and even helps improve your home’s air quality.

So don’t let anyone tell you all air handlers are pretty much alike. Fact is the CBX32MV does its job better, making you more comfortable.

less energy and noise; greater savings

Greater efficiency and savings

The CBX32MV is specifically designed to work with a matched outdoor unit— the air conditioner or heat pump—to deliver optimum performance and maximum energy efficiency. The air handler’s variable speed motor uses

far less energy than conventional single-speed motors. So your home feels great and you save money, too.

Significantly reduced sound levels

The CBX32MV is built to be quiet. Its variable speed motor ramps up slowly, so there’s no noisy blast of air at start-up. Low-speed fan operation keeps

things quiet, too. And to further minimize sound, the blower compartment is surrounded by extra-thick insulation.

Uses

2/3 less energy than competitive single-speed models*

CBX32MV

Quiet, efficient, environmentally responsible air handler.

* Compared to air handlers with conventional single-speed blower motors, the CBX32MV’s variable speed motor uses two-thirds less electricity.

Innovative features make your home feel more comfortable.

Variable speed technology makes all the difference.

Designed to deliver a higher degree of comfort and innovation, the CBX32MV uses advanced variable speed technology to circulate air throughout the home. By operating at a range of speeds, the CBX32MV offers more precise control and helps to reduce sounds and maximize energy efficiency.

During warmer weather, the CBX32MV works with your air conditioner or heat pump to provide consistent cooling, while also lowering humidity levels for improved air quality.

icomfort ™ -enabled

To get maximum performance from the

CBX32MV, just add the icomfort ™ Touch

thermostat. The easy-to-use icomfort Touch can be programmed in minutes.

It allows the air handler to exchange information with other icomfort-enabled home comfort system components and make adjustments as needed, so you feel comfortable without having to think about it.

More-breathable air

During hot weather, the

CBX32MV provides continuous air circulation while cooling your home. The variable speed motor allows your air conditioner to remove moisture from the air for improved comfort and air quality. And low-speed fan operation increases the effectiveness of your filters, allowing them to capture and remove more allergy-aggravating contaminants.

A friendlier refrigerant

The CBX32MV is optimized to work with air conditioners or heat pumps using the chlorine-free R-410A

refrigerant, which meets the U.S. EPA’s most stringent environmental guidelines.
