4. High Condenser Temperature Alarm (clogged lter) (E7)

and should be checked twice monthly and cleaned when necessary. The unit is also
equipped with a condenser thermistor to determine if the condenser or condenser air
lter is excessively dirty. If the condenser thermistor detects a temperature that exceeds

After cleaning the lter, the alarm will automatically reset once the temperature at the
condenser outlet drops below 136.4°F (58°C).
