Cooling
Your air conditioner is designed to cool in warm weather when the outside temperature is above 60 °F (15.6 °C) and below 115 °F
(46.1 °C), so it won’t cool a room if it is already cool outside.
Condensation is normal
Air conditioners actually pump the heat and humidity from your room to the outside. Humidity becomes water, and your air
conditioner will use most of the water to keep the outside coil cool. If there is excessive humidity, there may be excess water that
will drip outside. This is normal operation.
Frosting
This usually occurs because of insufficient airflow across the coils, a dirty filter, cool damp weather, or all these. Set the SYSTEM
mode to FAN ONLY and the frost will disappear. Setting the thermostat a little warmer will probably prevent the frosting from
recurring.
Noises
All air conditioners make some noise. Friedrich units are designed to operate as quietly as possible. An air conditioner mounted in
a wall is quieter than one mounted in a window. It is important to ensure that the chassis seal gasket is properly installed (refer
to SPECIFICATIONS FIGURE 205).
Unit Cooling Mode
Once the ambient temperature rises past the cool demand threshold (Cool Set Point + 1.5 ˚F) (see figure below),
and the compressor is not locked out, the cooling cycle begins. As shown in the figure below, the fan is started 5
seconds prior to the compressor. Once the ambient temperature has been lowered to the cool set point (Cool Set
Point minus .25 ˚F), the cooling cycle starts to terminate by shutting off the compressor. After a 30 seconds delay,
the fan is shut off. (See figure below for graphic details)
