Cooling and heating capacities are based on the following conditions: Fan is based on High and
Ultra High. The figures in parenthesis indicate the heat reclaimed from the heat recovery ventilator.
Operation sound measured at 1.5m below the center of the unit is converted to that measured in
an anechoic chamber, built in accordance with JIS C1502 condition. The actual operation sound
The sound level at the air discharge port is about 8-11dB higher than the unit's operating sound.
For operation in a quiet room, it is required to take measures to lower the sound, for example install
Efficiency is measured under following condition: ratio of rated external static pressure has been
Feed clean water. If the supply water is hard water, use a water softener because of short life. Life
of humidifying element is about 3 years (4,000 hours, under the supply water conditions of
During the heating operation the freezing of the outdoor unit coil increases, heating capacity
decreases and the system goes into defrost operation. During defrost operation the fans of the
units continue driving (factory settings), the purpose of this is to maintain the amount of ventilation
When connecting with a VRV Heat Recovery outdoor unit, bring the RA (exhaust gas intake) of this
unit directly in from the ceiling. Connect to a BS unit identical to the VRV outdoor unit (master unit),
When connecting the indoor unit directly to the duct, always take the same system on the indoor
unit as with the outdoor unit. Perform group-linked operation and make the direct duct connection
settings from the remote controller. (Mode No. '17 (27)' -first code n° '5' - Second Code n° '6') Do
not connect to the outlet side of the indoor unit, depending on the fan strength and static pressure

When calculating the capacity as indoor units, use 5.6kW.
Cooling capacities are based on: indoor temperature: 27
Heating capacities are based on: indoor temperature: 20
