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. If you want to cool a room in the spring or fall, select the FAN ONLY mode and set the Fresh Air/ Exhaust air control to Fresh Air. This

will bring in a supply of cooler outside air.

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

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).
