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 Cassette / NEW Outdoor Unit.
The new Cassette / new Outdoor models are possible to have address setting for twin / triple control or group control
automatically when main power supply is switched on.
(Manual address setting is also possible by using DSW1 switch on the indoor unit P.C. board.) However,
this address setting is
only possible when proper wiring connection is made and indoor unit must be of original unit
.
1.1. Example of trouble during test operation
If the below phenomenon is found during test operation, wrong address setting is possible.
Therefore, please inspect the address setting.
1. LCD display of the wired remote control is not illuminated 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 OFF/ON button is ‘on’.)
(For normal operation, the outdoor unit will only start its operation after 3 to 5 minutes upon pressing the OFF/ON button.)
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 of master and slave etc.
1.2. Caution during test operation
Do not touch the remote control button 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 the main power supply switch is ‘on’, the P.C. board will automatically memorize the connecting system.
Consequently, when initial power supply is ‘on’, there mustn’t be any interchanging of units even of the same type and same
capacity unit.
Therefore, connection of the unit to another system is prohibited.

2.2. Low-noise outdoor units
4
2.2.1. Product features
•
• •
•
Low-noise design improves comfort in surrounding
areas
1. The noise-suppressing winglet fan is a result of new
research into vane design theory. The unique curved
shape suppresses the generation of vortexes, thus
reducing air flow noise.
2. The adoption of double-orifice rings reduces air
passage resistance.
3. Strengthening of the noise insulation materials in the
compressor and the sealing-in of mechanical noise
allows vibration noise to be greatly enclosed and
suppressed.
4. The heat exchanger has an L-shaped design to allow air
to flow more smoothly.
5. Noise is automatically reduced further during night-time
operation with lower outdoor air temperatures.
2.3. Greatly improved workability
increases system renewal
capability
•
• •
•
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 and outdoor 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 or
one size larger. Effective utilization of materials reduces
working time and trouble. (Adaptor sockets are not
supplied.)
•
• •
•
Additional refrigerant charging unnecessary for 30 m
−
− −
− All models do not require any additional charging of
refrigerant for 30 m of pipe length. This makes
installation much easier.
•
• •
•
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. By connecting a drain elbow and a
discharge pipe, water leakages can be prevented even
when the unit is installed to a wall.
•
• •
•
Save space design allows units to be installed side-byside continuously
−
− −
− Servicing after installation can be carried out by
removing 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 in any of four directions
(forward, right, down, rear).
−
− −
− Small liquid pipe diameters of 9.52mm for 34BB model,
making installation work much easier.
•
• •
•
Centralized draining method
−
− −
− Even when multiple outdoor units are installed to a wall,
the drain outlets can be concentrated into a single drain
pipe. This makes installation easier and also improves
appearance.
5
2.4. A brand-new control method
using the latest in technology
•
• •
• Easier power supply wiring connection
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 drive
wires and signal wires. If a connection error is made, the
relay does not operate and current does not flow to the
circuit boards.
•
• •
•
Twin and Triple operation
−
− −
− Simultaneous air conditioning of wide spaces and
corners is possible. Indoor units of different
horsepowers 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.
•
• •
•
Separate indoor/outdoor unit power supplies
The power supply can be connected to (1) just the outdoor
units, or (2) to both the indoor and outdoor units.
•
• •
•
Easy test operation
Test operation can be carried out for both indoor and
outdoor units.
•
• •
•
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
connection configuration (twin or triple format) and remote
control functions such as automatic louvre operation and
cooling or heating mode are automatically detected and set
instantly.

2.8. New refrigerant Series [R407C]
pipe installation
2.8.1. Procedure
•
• •
• The new refrigerant (R407C) has a different composition to
the previously-used refrigerant (R22), so some contents
and method of pipe installation and charging work are
different from before. Care should be taken when carrying
out this work.
2.8.2. Installation and precautions
2.8.2.1. Before installation
1. Determine the installation division.
2. Check the refrigerant to be used.
•
• •
• Check that the refrigerant is R407C.
•
• •
• Check that the gauge pressure is at a maximum of 3.3
MPa.
3. Make a drawing of the Installation.
2.8.2.2. Installation
1. Install the sleeve and the insert.
2. Install the indoor unit.
3. Install the refrigerant piping.
•
• •
• Pipe materials (Phosphours Deoxidization Seamless
Pipe)
•
• •
• Refrigerant pipes which were previously used to carry
R22 must not be re-used. If replacing the indoor and
outdoor units, be sure to replace all refrigerant pipes
also.
•
• •
• Check the pipe thickness.
(1/4, 3/8, 1/2 : t = 0.8mm 5/8, 3/4 : t = 1.0mm)
•
• •
• Clean the inside of the pipes.
•
• •
• When storing pipes, seal both ends of the pipes and
store them indoors to prevent water, dust and other
foreign particles from getting inside.
•
• •
• Take care not to let any foreign particles (oxide scales,
water or dirt) get inside the refrigerant lines (same as for
R22).
■
Refrigerant pipe storing
Location Installation period Storing method
Outdoors 1 month or more Pinching
Less than 1 month Pinching or taping
Indoors Any
•
• •
• Pinching method
Close off the ends of the pipes with pliers or similar tool
and seal the opening by brazing.
•
• •
• Taping method
Wind PVC tape around the ends of the pipes to seal the
2.7. Group Control Equipment
7
openings.
•
• •
• Do not work for refrigerant piping on outdoor on rainy
days.
•
• •
• Seal by brazing.
•
• •
• Be sure to use only a non-oxidizing brazing material.
(Use nitrogen. Anti-oxidants cannot be used.)
•
• •
• When brazing pipes together, or when brazing copper
pipes and copper joints, use a brazing material (Bcup-3)
which does not require flux.
•
• •
• Flare processing and ester oil.
•
• •
• Sealing can be improved by applying ester oil or mineral
oil (the minimum amount necessary) to flares and flange
connections.
•
• •
• Due to the high hygroscopic tendency for ester oil, do
not mix or use any other impurities. (This can cause
deterioration of the compressor oil and problems with
the compressor.)
•
• •
• After preparing the refrigerant pipes, close both ends of
the pipes by brazing if not immediately connecting them.
•
• •
• A torque wrench must be used.
4. Install the drain pipe.
5. Install the ducts.
6. Insulate against heat.
7. Carry out the electrical work.
•
• •
• Connecting cables and power cables.
8. Make all necessary settings.
9. Prepare the outdoor unit foundation.
10. Install the outdoor unit.
11. Air-tightness test.
For the final check, there should be no pressure drop when
3.3 MPa is applied for 24 hours.
12. Vacuum drying.
Vacuum draw time 60 min. or more
* Vacuum pump capacity 60 l/min. or higher
•
• •
• D rawing the vacuum will remove any moisture.
•
• •
• The pressure after vacuum drawing should be 755
mmHg or less.
•
• •
• Use a special vacuum pump (with backflow-prevention
mechanism).
•
• •
• Gas must never be used for air purging.
13. Additional refrigerant charging.
•
• •
• Check that refrigerant volume is correct.
•
• •
• Be sure to charge refrigerant in liquid state.
•
• •
• Always charge in liquid state.
When the refrigerant is charged from the cylinder, the
composition may change greatly (compounds which do
not easily evaporate may remain inside the cylinder), so
the refrigerant must always be charged in a liquid state.
(It is recommended that a manifold with sight glass be
used.)
■ Boiling point at normal atmospheric pressure
(reference)
Refrigerant HFC32 HFC125 HFC134a
Boiling point -52°C -49°C -26°C
•
• •
• Use a special gauge manifold and charging hose.
•
• •
• If refrigerant leaks occur, replace all of the refrigerant
(same as for R22).
•
• •
• Note that a R22 leak detector cannot be use to detect
leaks.
•
• •
• Refer to the Installation Instructions included for the
correct charging amount.
•
• •
• Make a note of additional refrigerant charging amounts
in the record table.
14. Test operation and adjustment.
15. Organize documentation before handover.
16. Handover and explanation of operation.
•
• •
• Ventilation of closed rooms
R407C is a non-flammable refrigerant with low toxicity,
but in the gas state its specific gravity is heavier than
that of air, and so if leaks occur in a closed room,
suffocation may occur. Toxic gases may also be
generated if it comes into direct contact with flames, so
adequate ventilation must be provided.
