2. Air flow & static pressure conditions for fresh air intake
Be sure to use a duct fan (booster fan) when applying fresh air intake. As for sequential operation with the duct fan, see Item 3.
FRESH AIR INTAKE (Installation at site)
1. Location for installing fresh air intake
The fresh air intake duct can be connected by removing the knockout holes on the casing of the indoor unit and attaching the fresh air intake flange and duct. When applying fresh air intake, confirm that the mixed air is within applicable conditions as the intake air mixes with the ambient air.
