Safety Precautions
We have provided many important safety messages in this manual and on your appliance. Always read and obey all
safety messages.
WARNING
CAUTION
All safety messages will tell you what the potential hazard is, tell you how to reduce the chance of injury, and tell you
what will happen if the instructions are not followed.
Your safety and the safety of others are very important.
This is a safety Alert symbol.
This symbol alerts you to potential hazards that can kill or hurt you and others.
All safety messages will follow the safety alert symbol with the word “WARNING”
or “CAUTION”. These words mean:
Indicates a hazard which, if not avoided, can result in severe personal injury or
death and damage to product or other property.
Indicates a hazard which, if not avoided, can result in personal injury and
damage to product or other property.
NOTICE
Indicates property damage can occur if instructions are not followed.
WARNING
Refrigeration system
under high pressure
Do not puncture, heat, expose to flame or
incinerate.
Only certified refrigeration technicians should
service this equipment.
R410A systems operate at higher pressures
than R22 equipment. Appropriate safe
service and handling practices must be used.
Only use gauge sets designed for use with
R410A. Do not use standard R22 gauge sets.

Unpacking Instructions
STEP 1. Cut all 4 packing straps.
STEP 2. Remove wooden shipping bar dividers.
STEP 3. Remove top foam pads.
STEP 4. Slowly remove outer box, careful not to loosen decorative front.
STEP 5. Slide the foam front support for ward
STEP 6. Carefully lift decorative front box from foam front support
STEP 7. Remove decorative front and set safely aside
WARNING: Before Operating Your Unit
WARNING
Electrical Shock Hazard
Make sure your electrical receptacle has the
same configuration as your air conditioner’s
plug. If different, consult a Licensed Electrician.
Do not use plug adapters.
Do not use an extension cord.
Do not remove ground prong.
Always plug into a grounded 3 prong oulet.
Failure to follow these instructions can result in
death, fire, or electrical shock.
Make sure the wiring is adequate for your unit.
If you have fuses, they should be of the time delay type. Before you install
or relocate this unit, be sure that the amperage rating of the circuit breaker
or time delay fuse does not exceed the amp rating listed in Table 1.
DO NOT use an extension cord.
The cord provided will carry the proper amount of electrical power to the
unit; an extension cord may not.
Make sure that the receptacle is compatible with
the air conditioner cord plug provided.
Proper grounding must be maintained at all times. Two prong receptacles
The grounded receptacle should meet all national and local codes and
ordinances. You must use the three prong plug furnished with the air
conditioner. Under no circumstances should you remove the ground
prong from the plug.
Test the power cord
All Friedrich room air conditioners are shipped from the factory with a
Leakage Current Detection Interrupter (LCDI) equipped power cord. The
LCDI device on the end of the cord meets the UL and NEC requirements
for cord connected air conditioners.
To test your power supply cord:
1. Plug power supply cord into a grounded 3 prong outlet.
2. Press RESET (See Figure 1).
3. Press TEST, listen for click; the RESET button trips and pops out.
4. Press and release RESET (Listen for click; RESET button latches
and remains in). The power cord is ready for use.
NOTICE
Do not use the LCDI device as an ON/OFF switch.
Failure to adhere to this precaution may cause
premature equipment malfunction.
Once plugged in, the unit will operate normally without the need to reset
the LCDI device. If the LCDI device fails to trip when tested or if the power
supply cord is damaged, it must be replaced with a new power supply cord
from the manufacturer. Contact our Technical Assistance Line at (800)
541-6645. To expedite service, please have your model number available.

Control Panel Operation
Let’s check out how to control your air conditioner. On the control panel,
just to the left of the POWER
control panel function buttons and mode icons can be viewed in Figure 8.
Power On – Press the
power button will illuminate to indicate the power is on. The backlight on
the power switch will automatically dim to 20% intensity after 15 seconds
of inactivity. The remote control can also be used to turn power ON / OFF
(See Remote Control).
Display –
light. The back light has an automatic two (2) step dim function. After 15
seconds of inactivity, the display dims to 20% intensity. After an additional
120 seconds, the display switches off. Touching buttons will automatically
bring the display to full brightness.
There are four control push buttons on each side of the display.
SYSTEM Button – Allows the user to sequentially select,
, HEAT , and FAN ONLY operation. Press the button and
the display advances to the next mode. A new icon appears. At the same
time, the mode displays for two (2) seconds, then returns the display to
the temperature set point for modes other than FAN. Note that when the
heating function is not available, the system will automatically skip the
HEAT
and modes.
FAN MODE Button – Selects between automatic
operation. In the

Depending on your model, you can select between LOW, MED, HIGH,
When the
button is pressed, the fan speed is temporarily displayed
in the display window, plus a fan speed icon (triangle) changes to indicate
the new speed level. W
hen auto is selected,
fan speed automatically varies
depending on the set temperature on the control panel and the actual
room temperature. Let me explain. Say for example you’re working in
your garage and you need to open the big door for several
minutes. The
air conditioner will sense a wide difference between the set temperature
and the actual room temperature when this occurs the system fan speed
increases to MAX. The fan speed decreases (in step) as the temperature
difference decreases. When the set point temperature is reached the FAN
speed returns to the original setting.
SCHEDULE Button – The
button turns the schedule function on
and off. The current day of the week is indicated as a dot underneath
the day symbol. Pressing the
button a second time turns the
schedule function off. The schedule function comes preprogrammed with
recommended energy savings values (Addendum 1). The values may
be changed through the schedule program function (See Programmable
Thermostat).
UP and DOWN arrows – Pressing either
(UP) or (DOWN) button
changes the desired room temperature. The factory preset lower and
upper limits are 60° F (16° C) and 99° F (37° C). These buttons are also
used to navigate between function options when using the User Menu or
Maintenance Mode.
BACK Button .detceles neeb sah meti unem a retfa desu si nottub sihT –

DISPLAY/ENTER Button – This button is used in conjunction with User
menu and Maintenance Mode operation to select items.
This button may also be used alternately to

Maintenance Required – When maintenance is required, a service icon
appears on screen. This icon will not be dismissed until maintenance
has been performed. If the service icon
the icon
is established the service icon
goes away.
Wait – The WAIT icon
Whenever the compressor shuts off, system pressures must be allowed
to equalize. At this time, an internal timer begins a count-down from up to
240 seconds. If a demand for heat or cool occurs during this count-down
the WAIT icon
displays letting you know that the compressor will not
operate until the count-down has completed. This timer prevents damage
to the unit if it tries to start too quickly after it stops running. Normally the
WAIT icon
is off. Once the timer has cleared, the air conditioner will
heat or cool based on the temperature setting. Electric heat is not affected
by this timer.
Protection Alert (Freeze) – If the room freeze protection is active, the
display indicates this by showing Room Freeze Protection "FRZ". Once
temperature is less than 40° F (4° C), and the air conditioner is equipped with
electric heat, the room freeze protection will activate. The air conditioner
will run high fan and electric heat until the room temperature reaches
46° F (8° C). Pressing the
Low Battery – When the battery is low a warning display
button delays the freeze protection function
will be
inserted before other messages such as “COOL”. If the Low Battery
alert is on, the battery in the control unit must be changed. Refer
to the changing the battery procedure. Once the battery is changed, the
alert message will go off. Refer to Troubleshooting Tips. Under normal
conditions the battery life should be greater than 7 years.

other factors. Friedrich allows you to select the appropriate temperature
offset to make the temperature readout as accurate as possible for your
