Mitsubishi Electric Offers
Three Important Advantages
In today’s competitive environment, simply meeting industry standards, however
stringent, is not enough. Our aim is to exceed them. That’s why when it comes to
comfort, efficiency and durability: Mitsubishi Electric offers you a distinctive advantage.
We call it MEQ — Mitsubishi Electric Quality. And it's a new benchmark that results
in leading edge products, such as air conditioners that consume minimal power and
protect your investment with a long operational lifespan. You can also enjoy superb
reliability, as they’re built to endure the punishment of extreme weather conditions
year in and year out.
True Comfort is Yours to
Enjoy with Our Line-up
We create products designed to
ensure that you and your surrounding
will always be in a perfect harmony.
Whichever model from our Mr. SLIM
line-up you may choose for commer-
cial use in restaurants, stores, or
offices will be your guarantee of
exceptional comfort in every and all
operating condition.
Comfort
Optimum Cost Performance
and Energy Savings
MEQ results in air conditioners that
are rated among the best in the
industry in terms of quality and energy
efficiency. We strive for a perfect bal-
ance of performance, reliability, low
power consumption and long opera-
tional life span. This is complement-
ed by continuous introduction of new
technologies and components that
further reduce energy requirements
and improve eco-friendliness.
Efficiency
Rugged Construction, Rigorous
Testing, Long-lasting Operation
MEQ is behind a mindset that goes to
extremes to ensure higher quality
products that protect the initial
investment over years of reliable ser-
vice. We subject our indoor and
outdoor units to rigorous durability
testing, including harsher tempera-
ture extremes than likely found
anywhere in the world.

High performance, low power consumption,
and excellent reliability.
The MEQ Difference

Multi-language Display
Weekly Timer
The function of the weekly timer equipped can change the set
temperature in addition to the ON/OFF control. Up to 8 pat-
terns can be set for each calendar day.
Whatever your requirements may be, Mitsubishi Electric offers advanced
split-type heat pumps perfect for any interior, any need. Significantly
decreased noise levels enhance comfort while a long list of convenient
features allow for easy installation and far less maintenance. A variety of
system control configurations plus twin multi operation — where multiple
indoor units can be connected to a single outdoor unit — make
our units the first choice for the diverse applications of today.

Design uniformity improves installation flexibility
From the smallest 3HP unit to the largest 6HP model, the new high-
power ceiling cassettes offer a uniformly square 950 x 950mm width
and depth design. Thanks to the uniformity of the panel size, planning
for unit positioning in any room is enhanced and the installation of dif-
ferent capacity models within the same floor space is made possible.
Unit height of only 258mm [PLH-3]
The new high-power ceiling cassette models
boast slim body height for smooth
and aesthetic installation
even in limited
ceiling plenum
applications.

Automatic vane shutter
When the air conditioner is not operat-
ing, the vane shutter* closes automati-
cally to conceal the air outlet and
create an aesthetically appealing flat
surface.
* This feature will not activate when the vane is set at
fixed position.
Wide-flow air outlet
The new high-power ceiling
cassettes offer a wide-flow air
outlet that enables effective air con-
ditioning of atrium-type ceilings up
to 4.2 meters in height.
The demands of high-
ceiling applications such
as halls, showrooms or
shopping malls can now
be fully answered thanks to this powerful yet highly
efficient airflow.

Auto-flap shutter
When the unit is turned off, the
shutter closes automatically over
the air outlet to enhance the stylish
design. The shutter also functions
as a flap to adjust airflow angle to
ensure that comforting air reaches every corner of the room.
Enhanced noise suppression
Low-noise operation has been
achieved through the introduction
of a “near-silent” fan and a
design which minimises airflow
resistance.
Multi-directional piping
To reduce installation time, drain piping can be connected from left
and right. Refrigerant piping can also be connected from the rear, left,
right and base of the unit.
Easy removable filter
Convenient thumbscrews on the filters
enable the filters to be quickly removed for
easier cleaning.
Back plate installation guide
To save time and effort, the back plate installation guide provides clear
instructions on installation positions. The enlarged back plate secures
the unit firmly to the wall, while the support piece which lifts the unit
makes the left-side piping work much easier.
Drain lift-up mechanism (optional)
For greater installation flexibility, the drain water pipe lift-up mecha-
nism has been raised 800mm from the base of the unit.

Extra slim, extra stylish
Sleek and slim with stylishly curved lines, the PCH-GAK Series blends
right into any interior. It also features a single air outlet with an auto
vane that closes like a shutter when the unit is turned off to enhance
overall appearance.
Innovative auto vane system
The auto vane system swings up and down
automatically to distribute air more evenly
throughout the room.
Quiet and comfortable
Smoother airflow, an improved air vent design, and a slimmer fan
combine to provide exceptionally quiet operation — a mere 43dB on
high and 37dB on low (PCH-3GAK).
New direct suspension system
For easier installation, the PCH-GAK Series features a new direct sus-
pension system that makes it unnecessary to remove nuts and bolts
from the main body. A one-touch suspension system is also available.
Piping flexibility simplifies installation
All piping, including those related to drainage, can be connected from
the right, rear and top of the unit. This provides greater flexibility in
selecting piping layout and installation locations.
Flockless vanes
With the adoption of new flockless vanes, dirt and other impurities can
be cleaned off easily with mild household detergent.
Fan phase control plus microprocessor control allow
airflow settings to match ceiling height.
Drain water lift-up mechanism can be pre-installed
(optional).
