Cautions for the handling and installation place of outdoor air processing unit
①
stop with the thermostat based on the value of sensor A and the setting temperature by the remote control.
Remote control’s setting temperature indicates the outdoor air temperature that controls the start and stop of operation
by the thermostat.
When the thermostat is turned off, the operation is changed to the fan mode so that the outdoor air is blown out
directly into the room. For example if the remote control is set to 22°C in cooling operation, and if the outdoor air
temperature is 22°C or lower at that time, the unit will go into fan operation.
②
When there is a difference between the air-conditioning temperature in the room during cooling operation and the tempera-
ture of air blown out from the outdoor air processing unit, dewing water may drip from the unit.To prevent the dewing, provide
③
4JODF the air blow outlet on the outdoor air processing unit may blow out the outdoor air directly, orient the outlet in such a
way that it will not blow air directly to persons in the room.
④
4JODF the unit controls the thermostat start and stop by monitoring the outdoor air temperature, it is prohibited to monitor the room
temperature by means of the room temperature monitoring by changing the thermostat setting at the remote control side and the
optional remote thermistor. Otherwise, dewing water may drip from the unit at lower outdoor air temperatures during cooling operation.
