Optional AC2 Outdoor Unit Placement
The optional AC2 unit must be placed outdoors, with the
fan pointing away from the building. It should be at least 12
inches (30 cm) away from the building or other obstructions
on the back and sides for unimpeded return airflow. There
should be little or no obstruction in the fan (front) direction for at
least 30 feet (9 m), otherwise airflow and therefore overall per-
formance will be reduced.
In addition, there should be at least two feet (0.6 m) of
clearance on the electrical box and refrigeration piping side of
the unit to facilitate servicing and general maintenance.
If there is any expectation that heat rejection (air cooling)
mode will be required while there is snow on the ground, the
outdoor unit must be mounted high enough so that it remains
clear of snow and ice at all times. Since this is not likely, the
unit may be mounted at ground level in most cases. If required,
two different leg kits which add either 15" (38 cm) or 30" (76 cm)
of additional height are available as an accessories.
The AC2 must be bolted down to prevent a tipping hazard.
Note that no field installed filter-dryer is required, since
one is included in the indoor unit.
IMPORTANT NOTE: The line set between the
indoor and outdoor units must not exceed 70
ft (21 m) in length.
Outdoor Fan Speed Reduction
Should fan noise be a concern, for example if the outdoor
unit is mounted near a frequently open window, the outdoor fan
speed can be reduced (up to a maximum of 25%). This should
only be done if necessary, since a small loss in efficiency will
result.
The fan speed can be reduced via the LCD (see
terface & Menus
section) or PC App (see
section).
