What is Mr. Slim® Split-ductless Technology?
For decades split-ductless air-conditioning systems have been the quiet solution for cooling and heating problems around the world. Our quiet and powerful Mr. Slim systems have three main components: an indoor unit, outdoor unit and remote controller. These units are easily connected by refrigerant lines running through a small three-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 indoor 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 authorized contractor means you will be quickly enjoying the comfort Mr. Slim systems provide.

Why Mr. Slim Systems
Mitsubishi Electric is the industry leader in split-ductless air-conditioning technology, period. Our innovations have defined cutting edge technology for over 25 years. Compare and you'll see no one surpasses the Mr. Slim brand's performance for quiet, easy-to-use and energy-efficient operation. And since our split-ductless technology carries the Mitsubishi Electric name, you know every product is built to last. The bottom line is that the Mr. Slim product delivers ultimate comfort control for your home or office. It's true today and will be comfortably evident for years to come.

Can't We Just Stick A Window Unit There?
Sure you can usea, window unit, but it will block your view to the outside from any angle. It's also an open invitation for burglars to pay you a visit. Oh, and don't forget that old window units are also ugly, drippy, noisy and add no significant value to your home. On the other hand, Mr. Slim® products from Mitsubishi Electric are easy for your authorized contractor to install. They work quietly and don't leave a large, easily-accessed opening in your otherwise secure home. And split-ductless systems like Mr. Slim products also add value to your home. All-in-all, window units may be the easy solution, but Mr. Slim systems from Mitsubishi Electric are the smart solution. You get what you pay for when it comes to innovative and reliable air conditioning, and with Mr. Slim products you invest in the comfort for your home or business.

Where Can Mr. Slim Products Be Used?
Mitsubishi Electric Mr. Slim systems are the perfect solution for almost any spot cooling or heating situation. Our split-ductless systems can make an uncomfortably hot or cold room in an existing building comfortable again. 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 split-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. These systems are cooling and heating solutions that can fit into almost any space because smart engineering optimized the capabilities of the new R410A refrigerant and INVERTER technology to develop more efficient systems with smaller indoor and outdoor units. R410A refrigerant is also environmentally friendly with zero Ozone Depletion Potential (ODP). 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 systems are virtually unlimited. If a room is too hot or too cold, a Mr. Slim system can handle it!

INVERTER Technology for Superior Year-round Comfort and Performance

Select straight-cool and all heat pump outdoor units employ Mitsubishi Electric's INVERTER-driven compressor technology (Variable Frequency Drive) to provide exceptional, high-speed cooling and heating performance. Thanks to high rotation speeds, desired temperatures are reached more quickly than with conventional systems. So you can enjoy your ideal level of comfort without delay.

Like a car's cruise control, the system varies the compressor speed, thereby reducing power consumption which results in extra energy savings. This also means the system can engage without affecting other household appliances. The system adjusts itself precisely to the level needed to maintain a consistently comfortable indoor environment. Precise rotation speed control provides comfortable, consistent room temperature.

INVERTER Technology	Conventional Technology
High rotation speed provides fast cooling and heating.	Requires a long time to reach desired temperature.
Low rotation speed efficiently maintains desired temperature.	Has uncomfortable temperature fluctuation.
Low rotation speed keeps starting current low, leaving other appliances unaffected.	Needs heavy energy usage every time compressor turns on.
Precise rotation speed control provides comfortable, consistent room temperature.	Requires high starting current that affects other appliances throughout household.

High-speed Cooling and Heating
High rotation compressor speeds cool and heat a room quickly, saving both energy and cash. The compressor speed is controlled to maximize efficiency, changing speeds according to the cooling and heating load of a room.

Optimum Comfort Year-round
Conventional units start and stop repetitively unlike INVERTER units that detect subtle changes in temperature and adjust compressor speed automatically. Low rotation speed efficiently maintains desired temperature to reduce temperature swings and provide a more comfortable climate.

Extra Energy Savings
For optimum performance INVERTER technology delivers only the energy needed to satisfy the cooling and heating load of a room, thereby reducing energy consumption.

Our CITY MULTI® product line also employs INVERTER technology. Ask about how the Mr. Slim® and the CITY MULTI INVERTER systems give you even greater performance capabilities and design flexibility, making Mitsubishi Electric products the best choice for any of your cooling and heating applications.

GLOSSARY
AIR CONDITIONER: A mechanical device used to control temperature, humidity, cleanliness, and movement of air in a confined space.

Btu/h (British Thermal Units per Hour): A term that is used to measure cooling or heating capacity.

CAPACITY or LOAD: A refrigeration rating system usually measured in Btu's.

COMPRESSOR: A pump found in a refrigeration or air-conditioning system, which pumps refrigerant through pipes between an outdoor and an indoor unit using pressure.

HEAT PUMP: An air-conditioning system that is capable of reversing the direction of refrigerant flow to provide either cooling or heating to the indoor space.

HSPF (Heating Season Performance Factor): A rating of the seasonal efficiency of a heat pump unit when operating in the heating mode.

HVAC: A term which stands for Heating, Ventilation, and Air Conditioning.

INDOOR UNIT: The air-handler of an air-conditioning system, which contains a heat exchange coil, filters and fan. Also, provides conditioned air into the space.

INVERTER TECHNOLOGY: Mitsubishi Electric's MSY, MSZ and MXZ and all P-Series outdoor units use INVERTER-driven compressor technology (Variable Frequency Drive) to provide exceptional indoor, high-speed cooling and heating. By responding to indoor and outdoor temperature changes, these systems reduce power consumption by varying the compressor speed for extra energy savings. The system operates only at the levels needed to maintain a constant and comfortable indoor environment. Our CITY MULTI product line also incorporates INVERTER technology.

MICROPROCESSOR: An electrical component consisting of integrated circuits, which may accept, store, control, and output information.

OUTDOOR UNIT:A component of an air-conditioning system which contains compressor, propeller fan, circuit board, and heat exchange coil. It pumps refrigerant to/from indoor unit.

REFRIGERANT: A gas/liquid substance used to provide cooling by direct absorption of heat.

REFRIGERANT LINES: Copper tubing through which refrigerant flows to and from indoor and outdoor units.

SEER (Seasonal Energy Efficiency Ratio): A rating of the seasonal efficiency of air-conditioning or heating units in cooling mode.

SPLIT-DUCTLESS SYSTEM: A system comprised of a remote outdoor condensing unit connected by refrigerant pipes to a matching. non-ducted indoor air-handler, and a remote controller. Special cases for introducing fresh air may call for limited ducting to air-handler from outside.
