EQUIPMENT DAMAGE HAZARD
Failure to follow this caution may result in equipment damage or improper operation.
In regions with snowfall and cold temperatures, avoid installing the outdoor unit in areas where it can
be covered by snow. If the outdoor unit is installed in areas where heavy snow is expected, a field
supplied ice or snow stand and/or field supplied--installed wind baffle should be installed to protect the
unit from snow accumulation and/or blocked air intake. Blocking the air intake may result in reduced
airflow, significantly reduced performance and damage to the equipment.
