Application Note 1013: Rated Capacity vs. Maximum Capacity ©2012 Mitsubishi Electric US, Inc. Due to continuing improvement, above specification may be subject to change without notice.
“Rated Capacity” is the system output capacity observed at standard AHRI rated testing conditions (47°F, and 17°F outdoor for heating). AHRI testing, performed to AHRI-210/240, requires the compressors to be run at a constant speed (60Hz) due to testing limitations. Any advantage gained by variable speed equipment is not exhibited in the test results. The test result values are listed in the AHRI Directory of Certified Product Performance, which is accessible through the AHRI website.
Application Note 1014: M-Series Dry Mode Description ©2012 Mitsubishi Electric US, Inc. Due to continuing improvement, above specification may be subject to change without notice.
Mitsubishi Electric/HVAC Division offers air conditioning equipment specifically for thermal comfort conditioning. While the units are designed for cooling and in the case of Heat Pumps for heating and not for humidity control there is a function to reduce the latent content in the air. Dry Mode is the operating mode for Mr. Slim and CITY MULTI indoor units used to reduce the moisture content of the air in the conditioned space served by the indoor unit – without significantly reducing the room temperature.
The relationship between the room temperature and the set temperature in Dry Mode is shown in Figure 1. Figure 1. The relationship between room temperature and set temperature Dry Mode uses the same coil frost prevention (defrost) as the Cool Mode to eliminate ice on the coil.

Application Note 1021: M&P Series High Altitude Applications ©2012 Mitsubishi Electric US, Inc. Due to continuing improvement, above specification may be subject to change without notice.
When air conditioners and heat pumps are installed in areas above sea level, capacity is reduced due to decreased air density. Equipment size must be increased to meet the load requirements. The following correction factors apply to CITY MULTI and Mr. Slim air conditioners and heat pumps for both heating and cooling operation. The indoor and outdoor units need to be sized based on the capacity reduction due to the decreased air density.
Adjusting equipment size for high-altitude applications is not supported by Design Tool software, so correction factors must be performed manually. No other adjustments are necessary in the system design and application. August 2012 Application Note 1021 ©2012 Mitsubishi Electric US, Inc.

Application Note 1022: Regarding Refrigerant Accessories ©2012 Mitsubishi Electric US, Inc. Due to continuing improvement, above specification may be subject to change without notice.
August 21, 2006 MEMO: Refrigerant Accessories Please be advised that we do not recommend the following accessories on our ductless air conditioners or heat pump units. Filter Driers: Our units are made in the factory under clean conditions and are brazed using dry nitrogen. They are charged with clean oil and new refrigerant. When the line sets are attached using flare connections the copper is clean. Under clean conditions filter driers are not necessary and will only cause pressure drops in the system.

Application Note 1024: Supplemental Heat Control ©2012 Mitsubishi Electric US, Inc. Due to continuing improvement, above specification may be subject to change without notice.
The P-Series, SEZ and SLZ indoor units, when installed with MXZ, PUZ or SUZ heat pump outdoor units, can interface and enable supplemental and auxiliary heat sources using an indoor board connector (CN-24 or CN-152, depending on indoor unit). For indoor units connected to PUY outdoor units, external heat control does not function. (Please note that at this time M-Series indoor units (MS/MSZ/MFZ) do NOT support any supplemental heat control or interface capabilities.
Supplemental Heat Control via CN-24 for PLA, PCA and SLZ Indoor Units CN-24 controls are indicated in Figure 1and require no setup at the remote controller. This function is only available in heating operation. Figure 1. CN-24 controls Figure 2 illustrates a typical wiring diagram for PLA, PCA and SLZ indoor units using CN-24: Figure 2.

Application Note 1025: No Simultaneous Heating and Cooling with MXZ ©2013 Mitsubishi Electric US, Inc. Due to continuing improvement, above specification may be subject to change without notice.
Multi-zone (MXZ) heat pump systems can connect two or more indoor units with one outdoor unit. Be advised that multi-zone systems with model numbers that begin with MXZ do not support simultaneous heating and cooling. All indoor units on these type models must all be in the same mode at the same time: either cooling or heating. The entire system will have a mode; individual indoor units set to the opposite mode will be in standby.
mode, having auto mode enabled on the connected indoor units does not guarantee that the system will switch modes when an indoor unit switches modes. Therefore, auto mode does not work as users expect on a multi-zone system, and is not recommended. Simultaneous Heating and Cooling For applications that require simultaneous heating and cooling, Mitsubishi Electric Cooling & Heating offers two options: 1. For smaller applications, multiple one-to-one single-zone systems. 2.
