1. SERVICE INFORMATION
Notice of Address setting forNEW Cassette / NEW OutdoorUnit.
The newCassette / newOutdoormodels are possible tohave address setting fortwin/ triple
control orgroup control automaticallywhenmainpowersupplyis switchedon.
(Manual address setting is alsopossible byusing DSW1 switchon the indoorunit P.C. board.)
However, this address setting is onlypossible whenproperwiring connection is made and
indoorunit must be of original unit.
1.1. Exampleof troubleduring test operation
If the belowphenomenon is found during test operation, wrong address setting is possible. /
Therefore, please inspect the address setting.
1. LCD displayof the wired remote control isnot illuminated
although the mainpower supplyswitch is‘on’.
2. LCD displayhad indicated as normal illumination when power
supplyswitch is‘on’, however outdoor unitcannot be operated. /
(But, itisnecessaryto take 3to 5minutes for outdoor unitto start
from the timing of remote control OFF/ONbutton is‘on’.)/ (For
normal operation, the outdoor unitwill onlystart its operation
after 3to 5minutes upon pressing the OFF/ONbutton.)
3. P.C. board had memorized wrong setting information.
A. Ifmainpower supplyisswitched on with the wrong connection.
B. When changing the connection or combination of units due to
re-installation etc.
-When changing the system from twinto triple(tripleto twin).
-When changing the system from group control to normal one
to one system.
2

-When making the replacement of units of master and slave
etc.
1.2. Caution during test operation
Donot touchthe remote control button and do not change anywirings forone minute whenthe
mainpowersupplyswitchis ‘on’. / (Because the unit is having automatic address setting during
the first one minute.)
1.3. Caution during automaticaddress setting
Whenthe mainpowersupplyswitchis ‘on’, the P.C. boardwill automaticallymemorize the
connecting system. / Consequently, wheninitial powersupplyis ‘on’, there mustn’t be any
interchanging of units evenof the same type and same
capacityunit. / Therefore, connection of the unit toanothersystemis prohibited.
2. FEATURES
2.1. Varietyof excellent features
-Compact design / Compact design 240 mm height, 840 mm width
and 840 mm depth. (3 HPunitbody)
-Automaticrestart function / When the electricpower resumes after
apower failure, the unitwill automaticallyrestarts the operation in
the pre-failure mode.
-Auto fan mode (indoor unit) / Auto fan mode isadded besides HI,
ME and LO. / Itautomaticallyadjusts the fan speed according to
the indoor temperature.
-Drymode function / Drymode can make acomfortableindoor
environment during wet season.
-Quiet operation / The sound level is41dB(A)for 28BB model
during High Fan speed and suitablefor offices, shops, homes etc,
when quiet operation isessential.
3

-Auto Swing Louvre / The airflow anglecan be changed
automatically(or manually)to an anglebetween 10° to 70° using
the remote control.
-Low ambient cooling operation / Cooling operation ispossibleat
outdoor temperature of / -5°C.
-Automaticchangeover function (heat pump models)
The unitautomaticallyswitches between cooling and heating in
accordance with operating load inorder to maintainacomfortable
indoor temperature.
-Hot start system (heat pump models)
-Pipes and drainage / Built-inupward draining mechanism.
2.2. Low-noise outdoor units
2.2.1. Product features
-Low-noise design improves comfort insurrounding areas
1. The noise-suppressing winglet fan isaresultof new research
into vane design theory. The unique curved shape suppresses
the generation of vortexes, thus reducing airflow noise.
2. The adoption of double-orifice rings reduces airpassage
resistance.
3. Strengthening of the noise insulation materialsinthe
compressor and the sealing-inof mechanical noise allows
vibration noise to be greatlyenclosed and suppressed.
4

4. The heat exchanger has an L-shaped design to allow airto flow
more smoothly.
5. Noise isautomaticallyreduced further during night-time
operation with lower outdoor airtemperatures.
2.3. Greatlyimproved workabilityincreases system renewal
capability
-Pipes that are one size larger can also be connected for renewal.
-Ifrenewing the system, existing refrigerant pipes can be utilized so
that onlythe indoor and outdoor units need to be replaced.
-For example, liquidand gas pipes from 10 years ago can be
connected to current pipes with the same size or one size larger.
Effective utilization of materialsreduces working time and trouble.
(Adaptor sockets are not supplied.)
-Additional refrigerant charging unnecessaryfor 30 m
-All modelsdo not require anyadditional charging of refrigerant for
5

30 mof pipe length. Thismakes installation much easier.
-Drainwater dripping-prevention structure
-The base of the outdoor unitisprovided with asingledrainholein
order to prevent drainwater from leaking out of the unit. By
connecting adrainelbow and adischarge pipe, water leakages
can be prevented even when the unitisinstalled to awall.
-Save space design allowsunits to be installed side-by-side
continuously
-Servicing after installation can be carried out byremoving the front
covers.
-Long pipe design for refrigerant pipes
-Maximum piping length of 50m for all models.
-Internal pipe connection
-Pipes are connected inside the units (inside the side covers),
making the final appearance more attractive.
-Pipes can be diverted outward inanyof four directions (forward,
right, down, rear).
-Small liquidpipe diameters of 9.52mm for 43BB and 50BB models,
making installation work much easier.
-Centralized draining method
-Even when multipleoutdoor units are installed to awall, the drain
outlets can be concentrated into asingledrainpipe. Thismakes
installation easier and also improves appearance.

2.4. Abrand-new control method using the latest intechnology
-Easier power supplywiring connection / Power supplywiring and
other wiring tasks can be carried out more easily.
-Twinnon-polar wires used to connect indoor and outdoor units.
-Adoption of connection error prevention circuits for drive wires
and signal wires. Ifaconnection error ismade, the relaydoes not
operate and current does not flow to the circuitboards.
-Twinand Tripleoperation
-Simultaneous airconditioning of wide spaces and corners is
possible. Indoor units of different horsepowers can even be used
incombination.
-Master unitand slave-units can be set automaticallyintwinand
triplesystems. Noaddress setting isnecessary.
-Multipleindoor units can be operated simultaneouslywith asingle
remote control. Note that individual operation isnot possible.
-Separate indoor/outdoor unitpower supplies / The power supply
can be connected to (1) just the outdoor units, or (2) to both the
indoor and outdoor units.
-Easytest operation / Test operation can be carried out for both
indoor and outdoor units.
-Automaticsetting initialization function (Remote control and
Indoor unit) / Inaccordance with the indoor and outdoor units
7

connected and the connection methods, conditions such as the
connection configuration (twinor tripleformat) and remote-control
functions such as automaticlouvre operation and cooling or
heating mode are automaticallydetected and set instantly.
2.5. Wired Remote Control
-The new design includes an easily-visiblered pilot lamp. The
power can be turned on and off at asingletouch, without opening
the cover.
-Has abuilt-inthermistor, allowing indoor temperature detection in
accordance with indoor conditions byswitching with mainunit
thermistor.
-Twinnon-polar wires make installation work easy. (10 mcable
supplied as accessory.)
2.6. Wireless Remote Control
