RESTRICTIONS APPLICABLE WHEN PERFORMING THE CHECK
RUN
When the Check run starts, all indoor units connected to the outdoor unit will start to run
automatically. During the Check run, you cannot check the operation of the indoor units
separately. After the Check run, check the operation of the indoor units separately in normal
operation.
The operable temperature ranges for the Check run are: outdoor temperature -15 to 46ºC; indoor
temperature for cooling 18 to 46ºC; indoor temperature for heating -15 to 37ºC.
In the check run, the conditioner will automatically switch between cooling and heating
depending on the outdoor temperature and indoor temperature. If the outdoor temperature or
indoor temperature is outside the above operable temperature range, wait until the temperature
is within the operable range and then perform the Check run.
Please do not conduct the Check run with all the windows in the room closed. Otherwise the
indoor temperature could get too low or too high.
Depending on the difference of the indoor temperature of each room, a judgment may be
impossible.
