1) The above table shows the correlation of External Static Pressure & AIR FLOW.
2) Duct work must be designed within the range of
on installing the unit.
3) Change the connection of the indoor fan motor connector to increase the moror speed to dbtain
similar CFM at 15mmAq stastic pressure.
4) If duct work is designed under
External Static Pressure, adjust the External Static Pressure
applying air damper.
