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).

2.2.1. 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...

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 installa tion and charging work are
different from before. Care should be taken whencarrying
out this work.
2.8.2. Installation and precautions
2.8.2.1. Before installation
 1. Determine the installa tion division.
 2. Check the refrigerant to be used.

• •  • 
W hen brazing pipes together, or when brazing copper
pipes and copper joints, use a brazing material (Bcup-3)
which does not require flux.
