(1) All models employ R410A, with RoHS compliance.
(2) Industry leading COP.
Thanks to achievement of the highest COP level in the industry, the energy consumption has been cut by 39~49% compared with
our former models (constant speed models).
(3) Energy labeling "Class A"
MHI models have cleared the class A standard, the highest energy saving level, with their high COP (coefficient of performance).
(4) The microcomputer chip is installed in the indoor unit and outdoor unit. There is no need for the unit to communicate between the
outdoor and indoor units so the unit is more resistant to electromagnetic noise thus the incidence of microcomputer malfunction
has been reduced. The compressor in the outdoor unit has its own self protection function, that reacts according to abnormal high
pressure and excessive high temperature.
(5) Wide range of operation
Heating and cooling operation at -15°C Our new advanced technology has expanded the heating and cooling operation range.
This permits installation of the units considering a heating and cooling operation under a low outdoor temperature condition down
to -15°C .
(6) New remote control for all indoor units
Applying nonpolar 2-core in new remote control line, it is very convenient for installation including renewal case.
(7) There are only three power lines between the outdoor and indoor unit. One cabtyre cable with 3 wires encased in one sheath is
enough for conducting the wiring work between the outdoor unit and the indoor unit. This contributes to simpler wiring work in
the field.
(8) All air supply ports have auto swing louvers. (Only case of FDTC, FDT
speeds of high, medium and low.
(9) All models have service valves protruding from the outdoor unit for faster flare connection (FDCVA802, 1002: Only a gas side is
brazing) work in the field.
(10) The size and weight of the outdoor units in the SRC40~60 and FDC71 Series have been greatly reduced. Use of an inverter has
also improved energy conservation and economy.
(11) Compared to the previous models, a single fan is used in the FDC100~140 outdoor unit models and forward blowing is used in
the FDC200 and FDC250 models,resulting in markedly reduced weight and greater compactness.In addition, use of an inverter
makes these units much more economical compared to the previous fixed speed units.
