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
 
    • 
• •  • 
The height is only 36cm and can be installe d even where
the space is limited.
2.1.2. Automatic restart function
 
    • 
• •  • 
W hen the electric power comes back after a power failure,
the unit itself automatically restarts the operation in the pre-
failure mode.

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 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 charging
unnecessary for...

2.4.2. Separate indoor/outdoor unit
power supplies
The power supply can be connected to (1) just the outdoo r
units, or (2) to both indoor and outdoor units.
2.4.5. Twin operation
 
    • 
• •  • 
Simultaneous air conditioning of wide spaces and corners is
possible. Indoor units of different horsepowers and models
can even be used in combination.

Refrigerant pipes which were previously used to carry
R22 must not be re-used. If replacing the indoor and
outdoo r units, be sure to replace all refrigerant pipes
also.
