(*Note (2))
See the section “12.1.10.2 or 12.1.10.3”.
Check if the setting is within the range of use on the PQ diagram.
If out of range, adjust until it becomes within the range of use.
In the case of identical setup, it is possible to omit this operation check if judged
unnecessary.

External static pressure setting completed
(1) Check the following items before performing the setting-check operations or auto airflow volume operations.
1) Check to make sure that the electrical wiring and ducting have been completed. Activate the stand-by mode.
In particular, make sure that the closed damper located in the middle of the duct is open, if installed. Also,
make sure that air filters have been installed inside the air inlet duct.
Check to make sure air is not leaking from the joints.
