Lennox Elite, CBK47UHET-018-230, 1.5 Ton, Constant Torque, Upflow/Horizontal Refrigerant Versatile Air Handler

Elite® Series

CBK47UHET Air Handler

High performance, high-efficiency, constant-torque air handler with refrigerant versatility

The CBK47UHET features all-aluminum Quantum™ Coil technology, renowned for its remarkable ability to resist corrosion from environmental contaminants found indoors. Combined with a constant-torque blower motor for quieter and more efficient operation.

These versatile air handlers come factory ready for R-410A refrigerant but can be converted to R-454B refrigerant at time of installation with a Refrigerant Detection System. This gives you flexibility during installation to meet the repair or replacement needs of your customers, while also allowing you to stock fewer air handlers in inventory and save space. See ‘Installation Flexibility’ below for more details on converting.

Energy Efficiency

• High-efficiency indoor coil – provides exceptional heat transfer and low air resistance for high-efficiency operation.
• Power Saver™ constant-torque motor technology for increased electrical efficiency using up to 33% less energy than permanent split capacitor (PSC) models.

Installation Flexibility

• Versatile Air Handlers can be converted to R-454B refrigerant at time of install with separate purchases of our Refrigerant Detection System Air Handler sensor and mounting bracket kit (27J27), Refrigerant Detection System Non-Communicating Blower Control Board (27A02), and an R-454B TXV (refer to R-454B TXV substitution chart for proper sizing). Converting air handler after initial installation violates the safety agency mark and, therefore, voids the warranty. See RDS component decision tree above for selecting conversion components.
• Two-piece cabinet for ease of installation in tight applications.

Quiet Operation

• Fully insulated cabinet that reduces sound for quiet operation and helps prevent cabinet sweating in hot and humid environments.

Home Comfort

• Optional electric heat to deliver an instant boost of hot air for added comfort. ECB47 Electric Heat Strips required for CBK47 Versatile Air Handlers. See Electric Heat Kit Compatibility Chart above for more information.

Reliable Performance

• Quantum™ Coil featuring a proprietary aluminum alloy exclusive to Lennox – is designed to weather the harshest elements.
• Antimicrobial drain pan resists growth of mold and mildew which improves indoor air quality and reduces drain line blockage.
