External Static Pressure & Air Flow
56 Universal System Air Conditioner
1. Ceiling Concealed Duct (ABNC-EL, ABNH-EL Models)
External static pressure given after substracting coil losses motor step factory installed.
External static pressure can be higher than the maximum given in the table, but the unit faces the problem of
freezing the coil.
The assured range of air-conditioner is in the only shady part and in the other part, the specification of
air-conditioner may differ with the above table.
If the static pressure of air-conditioner is out of the shady part, please adjust the static pressure.
* Change the connection of the indoor fan motor connector to increase the motor speed to obtain similar CFM
at 15 mmAq Static Pressure as at 10 mmAq Static pressure.
