MXZ-SM36NAMU Mitsubishi 36,000 BTU 4-Zone Smart Multi Heat Pump Unit – R410A

The Mitsubishi 36,000 BTU Smart Multi outdoor heat pump (MXZ-SM36NAM) is an extremely efficient heating and cooling option that can handle up to four zones if connected to M&P-Series indoor units, and up to 11 zones if connected to City Multi indoor units. 

Current model is MXZ-SM36NAM-U1. This specific outdoor unit allows you to connect a wide variety of indoor units. The MXZ-SM36NAM is part of Mitsubishi’s Smart Multi Series, catering to residential or commercial applications. This outdoor unit is a replacement for the retired MXZ-4C36NA model. This outdoor unit does require a branch box to operate. 

For proper installation, plan for:

1. Line Set – When hooking up indoor units to the MXZ-SM36NAM, 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 the branch box: 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. Branch Box – For the MXZ-SM36NAM, you’ll need one of two Mitsubishi branch boxes – PAC-MKA32BC (three-zone) or PAC-MKA52BC (five-zone), if you are installing M- or P-Series indoor units. You will use the three-zone branch box if you only have two or three indoor units, or you will use the five-zone branch box if you have four indoor units.

1. Port Adapters – Depending on the capacities of the indoor units, you may need port adapters. There are different units combinations that may require port adapters of different sizes. 

1. Disconnect Box & Electrical Whip Kit – The disconnect & whip kit  provides a safe and simple way to connect your outdoor condenser to your 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.
