Therefore when applying these units in a residential application make sure that the units
are not mounted at the top of the stairs blowing directly onto a wall or inside a niche or cut
out in a room.
Again the temperature sensor is designed to sense the returning air after it has been
supplied to the room, extracted the heat and humidity and then returned to the unit, not
when it has been bounced directly back off a wall or other obstacle.
Ambient
As standard the units are capable of cooling down to an ambient of 65 DegF, which is
sufficient for the majority of residential applications.
Indoor unit Location
For optimum unit operation the High Wall Indoor unit should be mounted a minimum of 6
feet from the floor. A minimum height of 4 feet must be maintained for correct unit
operation. Ensure air flow is never directly straight onto areas where people may sit or
congregate, as the temperature difference between Supply and Return air will be
approximately 35 DegF.

The Outdoor units are designed to operate with extremely low noise levels compared to
the standard US condensing unit, this allows the outdoor units to located in areas closer to
property lines, however when locating the
