Remote Controller
(Optional)
Remote Controller encases a sensible thermostat to ensure accurate temperature control.
The Microcomputer
Type Deicer
The microcomputer type deicer is capable of sensing both refrigerant and outdoor temperature with its
highly sensible dual thermistors, and eliminates such waste as that defrosting is accomplished although the
outdoor coil is frosted only thinly when outdoor temperature is low.
Thus, the microcomputer type deicer not only saves unnecessary power, but also ensures constant
comfortable heating. In addition, the deicer is capable of selecting defrosting cycles, longer or shorter
depending on the volume of frost on the outdoor coil.
Evaporator and
Condenser
Efficient cross fin coils are used: the unique waffle louver fins*1 maximize heat exchange efficiency, while
the Hi-XA copper tube*2, featuring an inner spiral groove, fully exploits refrigerant turbulence to help
increase heat exchange efficiency. The result is substantial energy savings.
The fin of the heat exchanger is finished with special acrylic coating (PE fin), and highly resistant to
corrosion due to acid rain, sea breeze, etc.

Heating Capacity at
Low Outdoor
Temperature
The heating capacities tabulated do not include capacity drop during frosting period and defrosting
operation.
Namely, the integrated heating capacities in consideration with capacity drop during frosting period and
defrosting operation are obtained from the following formula.
Integrated heating capacity = (Capacity tabulated) X
(Integrated correction factor during frosting period) (kcal/h)

Capacity
Note: Integrated heating capacity means that heating capacity during one cycle (between defrosting period and
defrosting period) as shown on Page 5, which is integrated and converted to heating capacity per hour.
