1.1 GENERAL
INFORMATION
1.1.1 Specifi c features
(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 24~38% 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 (coeffi cient 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) 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 fi eld.
(6) All air supply ports have auto swing louvers. (Only case of FDTC, FDT, FDEN and FDKN models). The indoor fan motor has
three speeds of high, medium and low.
(7) All models have service valves protruding from the outdoor unit for faster fl are connection (FDCVA802, 1002: Only a gas side is
brazing) work in the field.
(8) The size and weight of the outdoor units in the FDCVA 151~251,302 Series have been greatly reduced. Use of an inverter has also
improved energy conservation and economy.
(9) Compared to the previous models, a single fan is used in the FDCVA402~602 outdoor unit models and forward blowing is used
in the FDCVA802 and FDCVA1002 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 fi xed speed units.
(10) Realization of signifi cant reduction in size and weight compared with our former models, applying front blow outlet on all models.
Reductions are 50% in weight of 6HP, 72% in volume of 8HP and 63% in the foot print of 8HP.
