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 hav e fus es, t hey sho uld b e of the t ime d ela y typ e. B efor e you ins tall
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
must be replaced with a grounded receptacle by a certifi ed electrician.
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

Control Panel Operation
Let’s check out how to control your air conditioner. On the control panel,
ju st t o the lef t o f th e POW ER
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 – The display is a high effi ciency LCD with a built-in white back
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
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
AUTO
modes.

the
button is pressed, the fan speed is temporarily displayed in the
SPEED
display window, plus a fan speed icon (triangle) changes to indicate the
new speed level when 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.
