MXZ-5C42NAHZ - Mitsubishi H2i® Hyper-Heating 42,000 BTU 5-Zone Heat Pump Unit

Regular price $4,540.50

The Mitsubishi 42,000 BTU low temperature multi-zone outdoor heat pump (MXZ-5C42NAHZ) is an extremely efficient heating and cooling option that can handle five zones at significantly lower temperature levels. 

Mitsubishi's current 42,000 BTU hyper-heat outdoor heat pump model is the MXZ-5C42NAHZ2. This specific outdoor unit allows you to connect a wide variety of indoor units that can range up to 24,000 BTU. The MXZ-5C42NAHZ is part of Mitsubishi's M-Series, catering to residential applications. This outdoor unit is perfect for customers located in regions that experience consistent sub 0 temperatures. 

For proper installation, plan for:

  1. Line Set - When hooking up indoor units to the MXZ-5C42NAHZ, you'll need a few types of refrigerant lines. This outdoor unit requires a branch box which uses  3/8" & 5/8" line-set. Additionally, there can be three different combinations of line-sets that connect indoor units to this outdoor unit: 1/4" & 3/8" for 6,000-12,000 BTU units, 1/4" & 1/2' for 15,000-18,000 BTU units, and 3/8" & 5/8" for 24,000 BTU units. Our line-sets kits come in different lengths; however, you can cut the copper pipes to fit your application.

 

  1. A Branch Box - For the MXZ-5C42NAHZ, you'll need one of two Mitsubishi branch boxes - PAC-MKA3 (three-zone) or PAC-MKA5 (five-zone). You will use the three-zone branch box (  PAC-MKA3) if you only have three larger units, or you will use the five-zone (  PAC-MKA5) if you are using all five zones. If you're planning on using more than one branch box, you'll need a Y-joint to split your refrigerant line to accommodate both.

 

  1. Port Adapters - If you are installing 2 1 BTU indoor units to this outdoor unit you will need a port adapter. There are other variations that may require adapters as well. Please read the installation manual to see which adapters you will need for a successful installation. 


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

 

  1. 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. 

 

  1. Outdoor Condenser Bracket (Optional)   This bracket provides an even surface, off the ground, on which to place your outdoor condenser. This bracket can handle up to 400 lbs and is great way to ground your outdoor unit system.
