1 SERVICE INFORMATION
Caution: ●Pb free solder has a higher melting point than standard solder; Typically the melting point is 50 - 70°F (30 - 40°C) higher. Please
use a high temperature soldering iron. In case of the soldering iron with temperature control, please set it to 700 ± 20°F (370 ±
10°C).
●Pb free solder will tend to splash when heated too high (about 1100° F/600°C).
Notice of Address setting for NEW Hide-Away / NEW Outdoor Unit.
The new Hide-Away / New Outdoor models are possible to have address setting for twin / triple control or group control
by automatic when main power supply is switched on.
(Manual address setting is also possible by using Dip switch on Indoor unit P.C. board.) However, this address setting is only
possible when made proper wiring connection and also Indoor unit should be original virgin unit.
1.1. Example of trouble at test operation
If found out as following phenomenon at test operation on site, it may have possibility of wrong address setting.
Therefore, please ensure of the address setting.
1.LCD display of wired remote control had not illuminate although the main power supply switch is ‘on’.
2.LCD display had indicated as normal illumination when power supply switch is ‘on’, however outdoor unit cannot be operated.
(But, it is necessary to take 3 to 5 minutes for outdoor unit to start from the timing of remote control ON/OFF switch is ‘on’.)
3.P.C. board had memorized wrong setting information.
a.If main power supply is switched ‘on’ with the wrong connection.
b.When changing the connection or combination of units due to re-installation etc.
• • •
• When changing the system from twin to triple (triple to twin).
• • •
• When changing the system from group control to normal one to one system.
• • •
• When making the replacement of units as master and slave etc.
1.2. Caution of test operation
Do not touch the remote control switch and do not change any wirings for one minute when the main power supply switch is ‘on’.
(Because the unit is having automatic address setting during the first one minute.)
1.3. Caution during automatic address setting
When main power supply switch is ‘on’, the P.C. board will automatically memorized the connecting system.
Consequently, when initial power supply is ‘on’, there will not be interchangeability of units even of the same type and same
capacity unit. Therefore unable to connect the unit to another system.

2.1. Variety of excellent features
2.1.1. Compact design, height 27 cm
• • •
• The height has been reduced to 27 cm (for 2.0HP to
6.0HP), the equipment can be installed in limited spaces.
2.1.2. Versatile installation
• • •
• The indoor unit is designed in order that air will also enter
from below, for easier installation under different conditions.
• • •
• The equipment has two drain outlets on the right and left
side for adoption to the installation conditions in the
building.
2.1.3. Easy maintenance
• • •
• Equipped with a filter as standard. The filter can be
removed in three directions for easier maintenance.
2.1.4. Static pressure selection
• • •
• The static pressure is selectable; 5mmAq or 7mmAq. The
static pressure can be selected according to the condition
of the duct.
2.1.5. Quiet operation
• • •
• The sound level is as low as 33db (A) for 2.0 HP. The
models is ideal for installation in offices, shop and houses
where quiet operation is important.
2.1.6. Auto fan mode operation
• • •
• Auto fan mode is added to existing modes Hi, Me and Lo.
It aotomatically adjusts the fan speed according to the
indoor temperature.
2.1.7. Dry mode function
• • •
• Dry mode can make a comfortable indoor environment
during wet season.
2.1.8. Automatic changeover function
(heat pump models)
• • •
• The unit automatically switches between cooling and
heating in accordance with operating load in order to
maintain a confortable indoor temperature.
2.1.9. Common design for Indoor unit
and Remote Control
• • •
• The indoor unit and the wire remote control are design as a
common specification between Cooling only and Heat
Pump models.
2.1.10. Wired Remote Control
• • •
• The new design includes an easily -visible red pilot lamp.
The power can be turned on and off at a single touch,
without opening the cover.
• • •
• A built-in thermistor, allowing indoor temperature detection
in accordance with indoor conditions by switching with main
unit thermistor.
• • •
• Twin non-polar wires make installation work easy, (10 m
cable supplied as accessories)
2.1.11. Automatic restart function
When the electric power resumes after a power failure, the unit
will automatically restarts the operation in the pre-failure mode.
2.1.12. Low ambient cooling operation
Cooling operation is possible at outdoor temperature of -5°C
(2.5 HP ~ 6 HP models), 10°C (2 HP model).

2.2. Greatly improved workability
increases system renewal
capability
2.2.1. Pipes that are one size larger can
also be connected for renewal
• • •
• If renewing the system, existing refrigerant pipes can be
utilized so that only the indoor units need to be replaced.
• • •
• For example, liquid and gas pipes from 10 years ago can be
connected to current pipes with the same size for one size
larger. Effective utilization of materials reduces working
time and trouble. (Adaptor sockets are not supplied.)
2.2.2. Additional refrigerant charging
unnecessary for 10 m
• • •
• All models do not require any additional charging of
refrigerant for 10 m of pipe length. This makes installation
much easier.
2.2.3. Drain water dripping-prevention
structure
• • •
• The base of the outdoor unit is provided with a single drain
hole in order to prevent drain water from leaking out of the
unit. Body connecting a drain elbow and a discharge pipe,
water leakages can be prevented even when the unit is
installed against a wall.
2.2.4. Easy test operation
• • •
• Test operation can be carried out for both indoor and
outdoor units.
2.2.5. Long pipe design
Max piping length: 25 (m) 18BB
Height difference/equivalent pipe
length 20/25
2.3. A brand-new control method
using the latest in technology
2.3.1. Power supply wiring is also easier
Power supply wiring and other wiring tasks can be carried out
more easily.
• • •
• Twin non-polar wires used to connect indoor and outdoor
units.
• • •
• Adoption of connection error prevention circuits for drives
wires and signal wires. If a connection error is made, the
relay does not operate and current does not flow to the
circuit boards.
2.3.2. Separate indoor/outdoor unit
power supplies
The power supply can be connected to (1) just the outdoor
units, or (2) to both indoor and outdoor units.
2.3.3. Automatic setting initialization
function (Remote control and
Indoor unit)
In accordance with the indoor and outdoor units connected and
the connection methods, conditions such as the configuration
(twin or triple format) and remote-control functions such as
cooling only or heat pump model are automatically detected
and set instantly.

2.3.5. Twin and Triple operation
• • •
• Simultaneous air conditioning of wide spaces and corners is
possible. Indoor units of different horsepowers and models
can even be used in combination.
• • •
• Master unit and slave-units can be set automatically in twin
and triple systems. No address setting is necessary.
• • •
• Multiple indoor units can be operated simultaneously with a
single remote control. Note that individual operation is not
possible.
