48,000 BTU 23 SEER Mitsubishi Multi-Zone Ductless H2i Hyper Heat Pump Condenser w/ Base Pan Heater

Mitsubishi MXZ-SM48NAMHZ-U1: Overview, Features, Warranty, and Required Equipment

Overview

The Mitsubishi MXZ-SM48NAMHZ-U1 is a heat pump condenser designed for use in multi-zone systems. Compared to using multiple single-zone condensers, a multi-zone unit is more practical in many applications since it takes up less space. With its integrated drain pan heater, the MXZ-SM48NAMHZ-U1 can heat down to -13°F, ensuring warmth even during the coldest months.

Features

• 48,000 BTU multi-zone heat pump condenser
• Variable speed inverter-driven compressor with quiet operation features
• Requires a branch box
• Hyper Heat technology for enhanced comfort down to -13°F

48,000 BTU

The MXZ-SM48NAMHZ-U1 is rated to handle a total of 48,000 BTU, which should be the same or greater than the total BTU count across all air handlers paired with it. In some cases, a certified pairing may have a higher BTU count total than the condenser's rating. However, anything higher than this rating can potentially lower the speed at which the unit can heat and cool, as well as limit the functional outputs of each air handler if they are all running at the same time.

Warranty

Mitsubishi offers a 5-year parts and 7-year compressor warranty on all its products. If the unit is registered online through the manufacturer after installation following state and local codes, the warranty is upgraded to a 10-year parts and compressor warranty.

Required Equipment

The MXZ-SM48NAMHZ-U1 is designed with only one set of line set ports, which allows it to support a higher BTU output than units with multiple sets. Therefore, at least one branch box is required for this unit to function, allowing it to connect to multiple air handlers. The condenser also requires air handlers, controllers, and other basic installation equipment to function, all of which are available at an additional cost.

With its variable speed compressor, the MXZ-SM48NAMHZ-U1 can provide more precise adjustments to the covered spaces with the right air handlers. This also slightly improves electrical efficiency by ramping the compressor up and down based on the unit's air handlers' needs, as well as providing a more stable temperature output from the connected air handlers to provide superior comfort.

For ease of control, many air handlers compatible with the MXZ-SM48NAMHZ-U1 can use any Mitsubishi-brand thermostat or adapter. The most convenient way to control the unit is through the Kumo cloud WiFi adapter, which allows each air handler to be accessed from anywhere with an internet connection. However, in most applications, you will need one thermostat or adapter per indoor air handler that you want to be able to control with it.
