Rheem RP14AZ Endeavor Line Classic Series iM Heat Pumps Instruction Manua

Features and Benefits

Swept Wing Fan Technology 1 : Features quieter operation and improved unit acoustics
Two-Stage Scroll Compressor 2 : Features two speeds (high and low) of cooling and heating, providing more precise

temperature control, lower humidity and greater efficiency when compared

to single stage compressors

Inverted Reversing Valve: Allows for faster heat transfer with gravity assist shifting and reduced joint stress for increased reliability
PlusOne ® Expanded Valve Space: 3 – 4 in. – 5 in. service valve space—provides a minimum working area of 27-square inches for easier access
PlusOne ® Triple Service Access: 15 in. wide, industry leading corner service access, two fastener, removeable corner and individual louver panels—makes repairs easier and faster
