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

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).

Ventilation of closed rooms
R407C is a non-fla mmable 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,
suffoca tion may occur. Toxic gases may also be
generated if it comes into direct contact with flames, so
adequate ventilation must be provided.
