Due to the hazardous nature of electrical and mechanical requirements only trained and
qualified personnel should install and service heating and cooling equipment.
WARNING
It is important to check airflow and make sure that the furnace does not operate above
the temperature rise specified in the specifications, Section 6. This is particularly
important if a cooling or heat pump coil has been installed. High limit thermal protectors
should never engage during normal operation of the furnace. The high limit protectors
are designed to engage during the improper functioning of the blower or when the air filter
has not been kept clean.
