Comfort is a home that’s cool and dry in the
summer and cozy and warm in the winter.
This environment is what you get with the
Mr. Slim system: perfect year-round comfort.
The M-Series systems install easily. Mounted
high on the wall, the indoor unit blends into
most room environments without taking up
any window space. These systems also
feature automatic cooling/heating change-
over, which automatically switches the
system between cooling and heating to
compensate for fluctuating temperatures.
They’re nearly silent because their fans
deliver air quietly and continuously with
only a gentle whoosh for constant circulation
and filtration. (This capability is the reason
Mr. Slim systems were the first choice for
thousands of churches, schools and librar-
ies across the U.S.) Our M-Series systems
are the perfect way to cool or heat any room
in your home. M-Series INVERTER systems
provide high-speed and efficient cooling and
heating performance to keep your home
consistently cozy year-round.
Superior INVERTER
Technology
Now you can benefit from technology that
outperforms conventional systems with
Mitsubishi Electric’s INVERTER technol-
ogy. Precise rotation speed control helps
you keep temperatures consistent. At high
rotation speeds you get faster cooling and
heating. At low rotation speeds the tempera-
ture is efficiently maintained, and starting
currents are kept at low levels so they do
not affect other appliances. Pulse Amplitude
Modulation (PAM) keeps efficiency high
by ensuring that the system effectively
uses 98 percent of input power supply.
No Ductwork Required
Mr. Slim systems require no ductwork, just
a small, three-inch opening for two refriger-
ant lines and control and power wiring to
connect the indoor and outdoor units. This
feature allows for quicker installation, less
mess, and a better-looking and more com-
fortable space. If you are adding on a room,
you don’t have to tie into an existing system
to steal cool or warm air from other areas in
the home. This advanced technology means
better room control and increased comfort
plus greater efficiency.
Total, Healthy Comfort
The POWERFUL mode is available to
cool or heat any desired space quickly by
lowering the set temperature in cooling
mode or raising the set temperature in heat-
ing mode by seven degrees. It increases the
fan speed for 15 minutes. Auto changeover
maintains consistent temperature in a room
by automatically sensing whether the space
needs cooling or heating. For challenging
cooling environments, low-ambient tem-
perature control means our systems perform
effectively in cooling mode even when the
external temperatures dip to as low as
14 degrees Fahrenheit. Even more important
you can benefit from our anti-allergen filter.
Using blue enzymes, this filter helps
minimize germs, bacteria, and viruses.
Control Technology
With the new A-Control system the indoor
unit is powered through the outdoor
unit. Three polarity sensitive wires plus a
ground conductor run from the outdoor to
the indoor unit providing both power and
communication. Advanced wireless remote
control is standard on all M-Series models.
On the INVERTER-driven units, an option
for a wired wall controller is available.
System Control in the
Palm of Your Hand
Mr. Slim’s M-Series offers a compre-
hensive remote controller that controls
temperature, fan speed and more.
Choose from four modes: COOL, HEAT,
AUTO and DRY. The controller also has
a 12-hour ON/OFF timer for one-button
control of your personal comfort. Our
new MSY(Z)-A24/D30/D36NA models
add the WIDE VANE button to evenly
distribute airflow to a wider angle
(150 deg.) from right to left, maintaining
a comfortable temperature across a wide
area. The M-Series INVERTER models
can tie into the P-Series wired controller
and CITY MULTI
®
M-NET with adapter
to give an on-the-wall controller option.
Warm Air, No Drafts
Our hot-start technology provides
warmth from the beginning. The fan
increases in speed as the coil is
warmed, reducing drafts so when
you want warm air, you’ll get it.
