Mitsubishi Electric Mr. Slim® Ductless Split-System. Wall Mounted Air-Conditioning Systems.


What is Mr. Slim Ductless Technology?


For many years ductless air conditioning systems have been the quiet solution for cooling and heating problems around the world. Our popular and proven Mr. Slim systems have two basic components: an indoor and an outdoor unit. These units are easily connected by refrigerant lines running through a small 3-inch opening in the wall or ceiling. The outdoor unit cycles the refrigerant through the lines to and from the indoor unit, where the air is conditioned and distributed
into the space. Installation is as simple as mounting the indoor and outdoor units,
connecting the refrigerant lines, and making a few electrical connections. An easy installation for your contractor means you’ll be enjoying the comfort Mr. Slim provides faster.


Why Mr. Slim?


Mitsubishi Electric is the industry leader in ductless air conditioning technology. Our innovations have defined cutting-edge technology for years. Compare, and you’ll see no one surpasses Mr. Slim’s performance for quiet, easy-to-use energy efficient operation.


Where Can Mr. Slim Be Used?


Mitsubishi Electric Mr. Slim systems are the perfect answer for almost any spot cooling or heating situation. For example, the ductless systems can make an uncomfortably hot or cold room in an existing building comfortable. Perhaps you are remodeling or renovating an older home or business built before ducted air conditioning was available. Because there is no ductwork to run, Mr. Slim ductless systems are both plaster-wall and brick facade-friendly so there’s no need to compromise the integrity of your home or office just to make each room comfortable. In addition, Mr. Slim systems are perfect for schools, universities, nursing homes, hospitals, restaurants, hotels, equipment rooms, office buildings, and churches. The versatility and variety of applications for Mr. Slim are virtually unlimited. If a room is too hot or cold, Mr. Slim almost always works!

MSM Multi Wall-Mounted Series Air Conditioners. MS-NW Indoor Unit 18,000 Btu/h Capacity (Dual MS09 Units) Possibilities.


That’s what the MSM system is about. The MSM features

a versatile multi-split design, meaning two MS09NW indoor units can be connected to a single outdoor unit (the MUM18NW). MSM systems are adaptable so you can install just one indoor unit first and add a second unit later. And reducing the number of outdoor units reduces electrical costs and means a cleaner, better-looking exterior. The MSM system is the easy way to have efficient, zoned air conditioning.


Our MSM18NW multi-split air conditioner provides the ultimate in
flexibility. You have the option to install one indoor unit first
and follow-up later with the second unit. When completed the system provides up to 18,000 Btu/h of cooling for two separate rooms.


Installation can be easier for your contractor because there is only one outdoor unit as compared to installing two separate systems. Each indoor unit is controlled separately with a hand-held wireless remote controller.

MS Wall-Mounted Series—Cooling and Heating


What is comfort? Comfort is a home that's cool and dry in the summer and cozy and warm in winter. This is what you get with the Mr. Slim® system, perfect year-round comfort. The MS/MSH system installs easily. Mounted on the wall, the indoor unit blends into most room environments without taking up any window space. The MS/MSH systems are the perfect way to cool or heat any room in your home.


No Ductwork Needed


Mr. Slim systems require no ductwork. There’s only a small, 3-inch opening connecting the indoor and outdoor units. This means easy installation, less mess, and a better looking home.


Wireless Remote Controller

Mr. Slim's M-Series systems offer three remote controllers: two
comprehensive remotes that offer complete control and a
simplified one when only control of temperature and fan speed are needed. Each runs three modes: Cool, Heat and Dry. They control fan speed and temperature setting and have 12-hour on/off timers, giving you one-button control over your comfort Our new MS/MSH24WN models add two exciting new features to the controller. First is a WIDE VANE button, which distributes airflow to a wider angle (150 deg.) evenly from right to left to ensure that a much more comfortable temperature is maintained across a wider area. Second is a button marked LONG, which boosts airflow reach to up to 36 feet. Together these two new features offer seven different airflow patterns, so the conditioned air always flows where you need it.


Hot-Start Technology


Mr. Slim heat pumps use our Hot-Start technology to provide warmth from the beginning, which reduces drafts, so when you want warm air, you'll get it.
