Power failure
If you have a power failure, the unit's auto-restart feature will resume operation
in the selected mode prior to the power failure.
Won't cool?
If your air conditioner operates, but won’t cool; check to see if the controls
are properly set. Check the filter and clean thoroughly if needed. Check to
see if the chassis seal gasket is installed (refer to Installation Instructions,
Step 8, page 8).
Won't run?
Make sure the power cord is plugged in completely. Check for a bad fuse,
tripped breaker or tripped LCDI Device. Refer to page 3 for LCDI reset
instructions and to confi rm proper fuse size.
For X-Star models only:
You can reset the circuit board by pressing the “MODE” button and the
“TEMPERATURE DOWN” button at the same time. The LEDs (small red
lights) for Hour, Start and Stop will begin blinking. Once this occurs, turn
the unit off by pressing the On/Off button once and then unplug the unit.
Finally, plug the unit back in and turn it on by pressing the On/Off button
once. All settings revert back to the factory default settings.
This is a warm weather appliance
Your air conditioner is designed to cool in warm weather when the outside
temperature is above 60°F (16°C), so it won't cool a room if it is already cool
outside. Also, it will not provide adequate heating when the outdoor ambient
temperature falls below 37°F (3°C).
Condensation is normal
Air conditioners actually pump the heat and humidity from your room to the
outside air. Humidity be comes 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 op er a tion.
Frosting
This usually occurs because of insufficient airflow across the coils, a dirty
filter, cool damp weath er, or all of these. Set unit 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. We build them to operate as quietly as
possible. An air con di tion er 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 Installation Instructions, Step 8, page 8).
Cleaning your air conditioner
The decorative front and the cabinet can be cleaned with warm water and a
mild liquid de ter gent. The indoor coil can be vacuumed with a dusting attach-
ment if it appears to be dirty. The outdoor coil can be gently sprayed with a
hose if you can get to it. If not, you might call your dealer for a more thorough
cleaning when needed. The air fi lter should be inspected weekly and cleaned
if needed by vacuuming with a dust attachment or by cleaning in the sink
using warm water and a mild dishwashing detergent. Dry the fi lter thoroughly
before reinstalling. Use caution– the coil surface can be sharp.
Heat pumps operate differently
If your unit is a "Y", or heat pump model, there are some things that you will
want to be aware of.
Some functions of a heat pump differ from your unit when it is used for
cooling:
1. It is normal for ice to form on the outdoor coil of the heat pump.
Moisture in the outside air, passing over the coil when very cold,
will form ice.
2. If the outdoor temperature drops below 37°F (-3°C), your heat
pump will automatically turn on the electric re sis tance heat. When
the temperature rises to 40°F (4°C) , the compressor will resume
the heat pump operation. If your unit is a 115 volt model (YQ07), it
is designed for use in warmer climates and has no electrical heat
feature, and will not provide adequate heat below 37°F(3°C).
Troubleshooting tips
Window installation kits - heat pump models
Friedrich YQ Heat Pump models are normally installed thru-the-wall and
are packaged and sold without the expandable curtain assemblies. The
WIKQ Curtain Assembly Kit may be purchased as an accessory for window
installations. This accessory can be ordered from your Friedrich Dealer.
When ordering a kit, state model and serial number of your unit.
