Notes 1) Factory default setting of fan speed is [STANDARD] which has standard static pressure.
If high static pressure setting is required, change setting to [HIGH SPEED 1] with remote controller on site.
(Regarding the setting method, refer to the user's manual of remote controller for detail)
Notes 2) When setting up high static pressure, do not operate the unit under the condition of 60Pa or lower of the external static pressure.
Notes 3) The fan speed of this model can be switched between two speeds.
