DC Inverter Ducted Air Conditioners
Technology. With over 5% of revenue invested in research and development programs,
Hitachi has developed world leading technologies including some of the most advanced air
conditioning systems currently available.
Reliability. For over 25 years Hitachi has been providing Australians with reliable, efficient
air conditioning products for both residential and commercial applications.
Easy Installation. Compact, lightweight and with flexible piping and wiring, Hitachi’s DC
Inverter Ducted units allow easy installation in any environment.
R407C. Be confident in knowing that your Hitachi Ducted DC Inverter system uses a
refrigerant that is non-toxic, non-flammable with zero ozone depletion.

DC INVERTER DUCTED AIR CONDITIONING
In a climate as diverse as ours you need a reliable temperature control
system that responds to the environment quickly and efficiently.
With over 30 years worldwide experience Hitachi has gained a reputation
for quality, reliability and industry leading technology.

Energy Efficient POWER SAVING DC INVERTER
Inverter technology allows a room to reach the required
temperature more rapidly and up to 30% more efficiently
than Constant Speed Systems. Inverter technology
also eliminates the frequent stopping and starting
often required by standard systems in order to maintain
consistent temperature conditions.
Rather than starting the motor up and stopping it
when the desired room temperature is reached, Hitachi
Inverters adjust (increase/decrease) the speed of the
compressor in order to maintain the desired temperature
in the most efficient manner.
DC COMPRESSOR AND FAN MOTOR
The “permanent magnet” motor featured in the DC
compressor maintains magnetic current without the need
for a constant source of electricity. This ensures the motor
suffers less ambient energy loss, delivering 10% greater
efficiency than equivalent AC inverters.
The outdoor fan motor also utilises a DC motor to further
improve system efficiency.
PAM SYSTEM
The Hitachi Power Active Model (PAM) Inverter System
suppresses electrical distortion to minimise power losses
to less than 1%, thereby maximising system efficiency.
Heating performance is particularly improved to
ensure efficient performance even when the ambient
temperature is -15˚C.
NEW CBC (CONDENSER BEST CONTROL) SYSTEMS
New CBC1 achieves high-efficiency cycles and lower
energy consumption.

PEACE AND QUIET
The beauty of Hitachi’s DC Inverter systems is the quiet
operation which can be attributed to innovative noise
reduction technology. The result is a hard-working,
efficient system that is amongst the quietest on the
market.
The newly designed fin and bell mouth combine to
minimise resistance for a smoother airflow through the
unit. The Delta-shaped edges on the fan deliver more
efficient air movement allowing for a smaller fan and
minimised noise levels.
Through advanced design developments, both in the fan
motor and the compressor rotor, electromagnetic noise
common in other inverter systems is significantly reduced.

Ergonomic DesignSLEEK, SPACE-SAVING DESIGN
The compact, lightweight design of Hitachi’s Ducted
DC Inverter systems provide increased flexibility when
it comes to positioning the outdoor unit.
The subtle vents, located throughout your home,
quietly and efficiently deliver cool or warm ducted
air throughout the building to maintain a constant
temperature, while the indoor unit can be easily installed
out of sight, in the ceiling or under the floor.
INTELLIGENT CONTROLS
Hitachi style flows through to the sleek, LCD
wall-mounted controls which reflect the sophistication
of the DC Inverter systems.
While an optional
Wireless Remote Control
is available for those
who want the ultimate
in convenience.
ZONING
Hitachi’s ducted units can be programmed into different
zone areas. You can choose to cool or heat only the
selected zones that are being used resulting in far greater
efficiency.
R407C REFRIGERANT
The new range of Hitachi inverters feature the refrigerant
R407C. While achieving similar energy efficiency levels of
previous refrigerants, R407C is
non-toxic, non-flammable with
zero ozone depletion.
IDEAL REPLACEMENT UNIT
In many cases existing wiring, circuit breakers and
refrigerant piping can be re-used due to the unique
features of Hitachi’s DC Inverter Ducted Units (contact
Hitachi for more details).
5 YEAR WARRANTY
The 5 year warranty on parts and labour
is your guarantee of the finest quality and
customer support.*
* 5 years domestic application. 1 year commercial application.
