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 5 to 115°F ●
(-15 to 46ºC); indoor temperature for cooling 64 to 114°F (18 to 46ºC); indoor temperature for
heating 5 to 98°F (-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.
