Sound Ratings; Outdoor Units; Indoor Units - Carrier 40KMC Product Data

Outside Air - - Up to 20% outside air can be introduced to the
40KMC or 40KMQ through pre- -punched knockouts.
If the 40KMC or 40KMQ is installed close to an outside wall,
some outside air can be introduced by running field supplied
ductwork to the unit. the amount of outside air that can be
introduced is determined by using the chart in Fig. 9.
If the cassette is installed in the middle of a room and is not close to
an outside wall, a power ventilation kit can be used to overcome
the static pressure in the ductwork and allow the needed CFM.
For applications that are very sound sensitive, it is recommended to
limit the fresh air intake to 10% when using a power ventilation
kit.

Air Discharge - - The 40KMC and 40KMQ units have four
discharge outlets that are equipped with motorized louvers for
better comfort. The user has three operating choices with the
louvers
1. AUTO - - The position of the louver is determined by the
mode in which the unit is running.
2. CONTINUOUS - - Louvers move continuously
3. STATIONARY - - Louver position is determined by the
user.
Air can be discharged from 4, 3, or 2 louvers. An accessory kit is
required to block the discharge from each louver.
Air Throw Data - - The following table shows the air throw data of
the 40KMC and 40KMQ units. The numbers shown indicate the
maximum distances reached by the airflow with a speed equal to or
greater than .66 ft/sec (0.2 m/sec) with louvers in the cooling
position.
