Caution
The information described in this catalog is for the purpose of selecting the appropriate products.
Before actually using this product, be sure to read the instruction manual carefully to ensure proper
operation.
1. A Solution to growing demand for energy sav-
ings: Automatic energy saving operation
• Under the energy saving mode, conditions can be set
automatically to ensure that the motor runs at peak effi-
ciency. This approach takes into consideration the axial
force of fans which frequently changes. This results in
minimized power consumption, and satisfies the increasing
demand for the greater energy savings.
2. Automatic stopping of the inverter cooling fan
while air conditioning system is not in operation
• By selecting cooling fan stop operation, the inverter cooling
fan can be stopped when the temperature of the inverter
cooling fan becomes low while the inverter operation
command is off.
• Although energy savings may appear minimal from the point
of view of the air conditioning unit itself, the total saving
effect that can be realized by the whole air conditioning
system is significant. Furthermore, the cooling fan stop
operation contributes to a more quiet operation, as the
cooling fan operation sound may be a nuisance at night.
3. Unnecessary to resort to any special sound-
proofing measures; Fuji inverter drives a motor
with silent motor sound.
• We have succeeded in eliminating most of the unpleasant
motor sound that usually comes from the motor which is
driven by the inverter.
The sound levels are comparable to those of commercial
power sources.
