High Energy Efficiency
Hitachi conforms to the
2002/31/EC Directive – 92/75/EEC
“Energy labelling Directive (ELD)” ,
which is applicable from June 2004
on all air conditioning products up
to 12Kw cooling capacity. The DC
inverter PAM technology helps us
to achieve the ‘A’ class, the highest
level of energy efficiency which is
clearly indicated on the standard
labelling system.
Advantages include:
Rapid start up
The variable speed compressor
(inverter) enables the system to
rapidly reach the desired room
temperature setting. Once the
desired room temperature has been
achieved the compressor rotation
speed is reduced, saving up to 30%
in energy usage (when compared to
conventional systems) without
compromising comfort levels.
Improved performance
The inclusion of a DC driven motor
delivers an enhanced performance
over standard AC motor driven
systems. This enhanced performance
can be as much as 10%!
Features and benefits
Rapid Start Up
Improved Performance
PAM – Minimised loss
of performance
Hitachi’s PAM (Power Active Module)
control system mirrors the current
pulse waveform to avoid distortion
and therefore achieve almost
100% power factor to enhance
power efficiency. This cutting edge
device is employed in all Hitachi
Mono/Multizone products for your
comfort and energy saving for our
environment. It ensures the efficient
use of input power and minimises
loss to less than 1%. The PAM
range boasts an industry leading
COP of more than 4.0.
All DC Inverter
As you would expect from an
Industry leader such as Hitachi,
we have been at the forefront of
technological development and
advancement. As the pioneer
of ‘DC’ Inverter driven Room
Air Conditioners, our units boast
the significant advantage of all
DC Inverter driven compressors
and fans. Enhanced inverter
performance and system
performance are achieved by
the addition of a ‘DC’ drive.
Conventional Inverter PAM Inverter

High performance
cooling at -10ºC and
heating at -15ºC
The cooling and heating performance
is even more impressive than
previously. The units have been
designed for cooling operation
under low temperatures down to
-10°C. At outdoor temperatures as
low as -15°C, the PAM controlled
range of inverter split systems
continue to provide high capacity
heating performance.
Digital DC Scroll
Compressor
The motor uses digital control to
maximise PAM control performance.
• Loss during high-speed revolution
is reduced thanks to digital control
of the motor.
• Shaft runout during high-speed
revolution is lessened by three
balancers mounted on the
crank shaft.
• Efficient operation with drastically
reduced refrigerant leakage is
ensured by the automatic
compression system, in which the
tip of the slewing scroll is kept in
absolute contact with the fixed
scroll, in addition to special
processing of the scroll surface.
DC Twin Rotary Compressor
Today all Monozone and two Multizone
room air conditioning units have Hitachi’s
new twin rotary compressor which has even
less vibration and even higher performance
efficiency than conventional rotary compressors.
• Two rotating cylinders ensure well balanced
rotation unlike the conventional single-rotary
type, thus greatly reducing any vibration noise.
• The compressor’s operation is magnificently
improved by the independent operation of
the cylinders leading to greater efficiency
and lower vibration.

Features and benefits
R410a Refrigerant
Hitachi is using the new R410a
refrigerant in all of its room air
conditioning products to ensure its
continual environmentally friendly
approach as well as the on going
development of techniques for
saving energy and reducing
power consumption.
Air Quality
Either the SPX-CFH5 or SPX-CFH11, washable
carbon and anti-bacteria air purifying filters are
included in all of Hitachi’s room air conditioning
products. This ensures that the micro dust,
pollen particles and odours that can collect on
filters can be easily removed. The filters can be
washed and reused up to 20 times.
Self Diagnosis System for
Easy Servicing
All air conditioning units are made
with easy servicing in mind. All
components can be easily reached
and self diagnosis is made easy.
Errors are easily identified by the
blinking patterns made by lights on
the LED outside the indoor and
inside the outdoor units.
SPX-CH5, SPX-CH11
Breathable structure. Micro level dust is absorbed by static electricity.
Reusable after washing.

Nano-Titanium Filter (Air Exchanger range only)
Automatic Operational Control
In our new Air Exchanger models we
have introduced the Hitachi state
of the art Nano-Titanium Catalyst
which dramatically improves the
functions of deodourisation, bacteria
elimination and anti-bacterial
measures. Titanium Oxide has been
used as a photocatalyst for many
years but Hitachi have now enhanced
it by reducing its size to a nanometer
– over 1000 times smaller than
ordinary bacteria agent.
This ultrafine catalyst can therefore
catch smaller microbes or bacteria
which may escape from other filters
leading to higher air quality circulating
around the room.
The comparison table easily shows
the size of the Nano Titanium
Catalyst in relation to other
ordinary anti bacterial agents
and also details the size of some
common bacteria in relation to
the size of the filter and showing
what does get through.
The Nano-Titanium does not
deteriorate or run out as particles
and dead fungi do not accumulate
on the surface, so it can be used
semi-permanently.
Both the SPX-CFH15 and
SPX-NFH1 filters are included.
Auto restart
If the auto start mode is selected at
the ON/OFF switch, then the unit
automatically resumes operation in the
mode that was in use before it was
switched off. This saves time for the
user on start up and setting selection.
Auto changeover
The built-in microcomputer
continuously selects the best
operating mode to achieve the
required heating and cooling
temperature. The sensor checks
the operating mode periodically
to provide maximum comfort
for the user. (Applicable to all DC
Inverter models.)
Easy to use remote control
All units come with a standard easy to use wireless or wired remote control,
equipped with 24hr timer. All commands are shown on the liquid crystal
display while convenient, frequently-used functions (sleep mode timer,
fan speed and louver control) can be operated with one touch buttons.
Monozone/Multizone
13
Extensive range and full
indoor/outdoor compatibility
The Hitachi Multizone range was the worlds first all DC Inverter Multisplit
system with zone by zone cooling or heating for up to four rooms.
Hitachi DC scroll and DC twin-rotary compressor, together with awardwinning DC inverter PAM technology, aid the achievement of a system
power factor of almost 100%, thus providing unparalleled performance
and efficiency. The all DC Inverter system ensures extremely sensitive
and accurate temperature control through fuzzy logic and offers
remarkably low sound levels.
The wide range of units have been designed for cooling operation under
low temperatures, down to -10°C. This feature enables cooling to be
obtained even in winter on buildings with high internal heat gains due to
lighting, people and machines, particularly in areas such as shops and
lecture rooms. The heating operation under low temperature, down to
-15°C can also be performed.
The recent integration of Multizone and Monozone employing R410A
refrigerant provides a comprehensive selection of DC inverter PAM mono
and multi split systems, maintaining full compatibility of indoor unit
throughout the range.
Monozone/Multizone compatible indoor unit range caters for all requirements
offering wall mounted, floor standing, 60cm x 60cm cassettes, and in the
ceiling duct units, designed to offer elegance and comfort to any application.
Comprehensive range/long pipe length
and easy installation
You can choose and connect freely from different types of indoor and outdoor
units depending on the number of rooms, width and shape of the room.
The single Monozone outdoor units work on a 20m to 30m maximum
length of piping, and are made in four different capacities.
Multizone outdoor units can have a maximum chargeless piping length
up to 70m when one outdoor unit is used with four indoor units in various
locations. A maximum combination of indoor units can provide a wide

Powerful
A bigger, compact flap delivers air quickly to every corner of the room and
the powerful, sweeping air flow eliminates dead zones and improves the
cooling and heating effect.
Silent
The trapezoidal blades cut the air diagonally to minimise air resistance and
the conical blade fan ensures a high airflow. With this diagonal air blow,
less friction is caused, which reduces noise and improves efficiency. The
fan diameter has been increased from the conventional 90mm to 100mm.
Efficient
The Lambda- shaped heat exchanger’s advanced design has a wide
suction area and graduation – design grill which both increase the
efficiency and performance of the heat exchanger. The wide suction
area increases the air intake which enables the unit to adjust the
room temperature quickly.
Clean
