1 SERVICE INFORMATION
Caution:
OPb 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).
OPb free solder will tend to splash when heated too high (about 1100° F/600°C).

2.1. Variety of excellent features
2.1.1. Compact design, height 27 cm
 
    • 
• •  • 
The height has been reduced to 27 cm, the equipment can
be installe d in limited spaces.
2.1.2. Versatile installation
 
    • 
• •  • 
The indoor unit is designed in order that air will also enter
from below, for easier installa tion under different conditions.
 
    • 
• •  • 
The equipment has two drain outlets on the right and left
side for adoption to the installa tion conditions in the
buildin g.
2.1.3. Easy...

[Product features]
2.2.1. Low-noise design improves 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 reduces 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...

2.3.1. 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 and outdoo r units need
to be replaced.
 
    • 
• •  • 
For example, liquid and gas pipesfrom 10years 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 supplie d.)
2.3.2. Additional refrigerant...

2.3.8. Centralized draining method
 
    • 
• •  • 
Even when multiple outdoo r units are installe d to a wall, the
drain outlets can be concentrated into a single drain pipe.
This makes installa tion easier and also improve
appearance.
2.4. A brand-new control method
using the latest in technology
2.4.1. Powersupplywiring 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 outdoo r
units.

2.5. New refrigerant Series [R407C]
pipe installation
2.5.1. Procedure
 
    • 
• •  • 
The new refrigerant (R407C) has a different composition to
the previously-used refrigerant (R22), so some contents
and method of pipe installa tion and charging work are
different from before. Care should be taken whencarrying
out this work.
2.5.2. Installation and precautions
2.5.2.1. Before installation
 1. Determine the installa tion division.
 2. Check the refrigerant to be used....

 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 time60 min. or more
* Vacuum pump capacity 60 l/min. or higher
 
    • 
• •  • 
Drawing 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.
