 Mitsubishi's current 12,000 BTU outdoor heat pump model is the SUZ-KA12NAHZ. This outdoor unit will support you even in sub 0 Fahrenheit temperatures! The SEZ-KD12NA4R1.TH horizontal ducted indoor air handler is an innovative piece of equipment. Slim in design and excellent in performance, this air handler is easy to install and is great for retrofit installs. This system is ideal for customers who own cape cods or just need their top levels of their homes conditioned well. 

For proper installation, plan for:
  1. Line Set - When hooking up SEZ-KD12NA4R1.TH (air handler) to SUZ-KA12NAHZ (outdoor condenser), you'll need refrigerant lines. You'll need 1/4" & 3/8" for this system. Our line-sets kit comes in different lengths; however, you can cut the copper pipes to fit your needs.

  2. Disconnect Box & Electrical Whip Kit - The disconnect box and electrical whip comes in each installation kit. It provides a safe and simple way to connect your outdoor condenser to your homes' electrical panel.

  3. Outdoor Condenser Plastic Pad (Optional) - This pad provides an even surface, free of debris, on which to place your outdoor condenser. It also comes with snow-risers to provide separation from the ground. 

  4. Wall Bracket (Optional) - A wall bracket is a simple and sturdy way to mount your outdoor condensing unit off of the ground and attached to your home.
