Product Overview
Merit® Series
CBK45UHPT Air Handler
Standard performance, standard-efficiency, three-speed air handler with refrigerant versatility
The CBK45UHPT features all-aluminum Quantum™ Coil technology, renowned for its remarkable ability to resist corrosion from environmental contaminants found indoors. Combined with a three-speed blower motor for air circulation you’d expect in an affordable, efficient package.
These -01 models come factory ready for R-410A refrigerant but can be converted to R-454B refrigerant at time of installation with a Refrigerant Detection System Sensor and Mounting Bracket Kit, Refrigerant Detection System Blower Control Board, A2L Labels, and an R-454B TXV. 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.
Energy Efficiency
- High-efficiency indoor coil – provides exceptional heat transfer and low air resistance for high-efficiency operation
- Multi-speed Permanent Split Capacitor (PSC) motor providing circulation in an affordable, efficient package.
Installation Flexibility
- -01 Air handler can be converted to R-454B refrigerant at time of install with our Refrigerant Detection System sensor and mounting bracket kit (26Z69), Refrigerant Detection System Blower Control Board (27A02), A2L labels, and an R-454B TXV (refer to R-454B TXV substitution chart for proper sizing). Converting after initial installation violates the safety agency mark and, therefore, voids the warranty.
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 back up heat to deliver an instant boost of hot air for added comfort
Reliable Performance
- Antimicrobial drain pan resists growth of mold and mildew which improves indoor air quality and reduces drain line blockage
