APPLICATION DATA
UNIT SELECTION
Select equipment that either matches or supports slightly more than
the anticipated peak load. This provides better humidity control,
fewer unit cycles, and less partload operation.
For units used in spaces with high sensible loads, base equipment
selection on unit sensible load, not on total anticipated load. Adjust
for anticipated room wet bulb temperature to avoid undersizing the
equipment.
UNIT MOUNTING (OUTDOOR)
Refer to the unit’s installation instructions for further details.
Unit leveling For reliable operation, units should be level in all
planes.
Clearance Minimum clearance (see Fig. 5) must be provided
for airflow. The condensing units are designed for freeflow
application. Air inlets and outlets should not be restricted.
Unit location A location which is convenient to installation and
not exposed to strong winds. A location that can bear the weight of
the outdoor unit and where the outdoor unit can be mounted in a
level position.
Do not install the indoor or outdoor units in a location with special
environmental conditions. For those applications, contact your
sales representative.
