WARNING: Before operating your unit
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 re lo cate this unit, be sure that the
amperage rating of the circuit breaker or time delay fuse
does not exceed the amp rating listed in Figure 1.
DO NOT use an extension cord.
The cord provided will carry the proper amount of electrical
power to the unit; an ex ten sion cord will not.
Make sure that the receptacle is compatible with
the air conditioner cord plug provided.
This insures proper grounding. If you have a two-prong
receptacle you will need to have the circuit replaced by
a certifi ed electrician with a grounded circuit that meets
all national and local codes and ordinances. Under no
circumstances should you remove the ground prong from
the plug. You must use the three-prong plug fur nished with
the air con di tion er.

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 meets the UL and
NEC requirements for cord connected air conditioners
effective August 2004.
To test your power supply cord:
1. Plug power supply cord into a grounded 3 prong outlet.
2. Press RESET (See Figure 2).
3. Press TEST (listen for click; Reset button trips and
pops out).
4. Press and release RESET (listen for click; Reset button
latches and remains in). The power supply cord is ready
for operation.
NOTE: LCDI device is not intended to be used as a
switch.
Once plugged in the unit will operate normally without the
need to reset the LCDI device.
If the device fails to trip when tested or if the power supply cord
is damaged it must be replaced with a new supply cord from
the manufacturer. We recommend you contact our Technical
Assistance Line at (800) 541-6645 ext. 662. To expedite
service, please have your model and serial number available.

For the best cooling performance & highest energy efficiency
Keep the filter clean
Make sure that your air conditioner is always in top performing condition by clean ing the fi lter regularly. Instructions for removing and cleaning the fi lter can be found on
page 5 and 6.
Provide good airflow
Make sure that the airfl ow to and from the unit is clear.
Your air conditioner puts the conditioned air out at the top
of the unit, and takes in unconditioned air at the bottom.
Airfl ow is critical to good operation. It is just as important
on the outside of the building that the airfl ow around the
unit exterior is not blocked.
Insulation
Good insulation will be a big help in maintaining desirable
comfort levels. Doors should have weather stripping. Be
sure to caulk around doors and windows.
Proper installation of seal gasket
Make sure the seal gasket has been installed properly to
minimize noise and improve effi ciency. If the seal gasket
has not been installed, please refer to your installation
instruction manual.
Unit placement
If your air conditioner can be placed in a window or a wall
that is shaded by a tree or another building, the unit will
operate even more effi ciently. Using drapes or blinds on
the sunny side of the dwelling will also add to your unit’s
effi ciency.

How to operate your Friedrich room air conditioner
(All models except YQ07 and EQ08. For YQ07 and EQ08, see page 6)
To start unit
If your air con di tion er is installed and plugged into a prop er
re cep ta cle, it is ready to go.
Function control
This dial control allows you to select cooling or heat ing at
three different speeds, as well as FAN ONLY.
Turn to OFF to turn everything off.
Turn to HI COOL or HI HEAT for quick re sponse.
Tur n to ME D CO OL or MED H EAT to ma in ta in a de sired
temperature.
Turn to LO COOL or LO HEAT for nighttime use, or
when demand is
low.
The FAN ONLY setting will circulate air in the room
with out the com pres sor coming on. The FAN ONLY
set ting can also be used with the EXHAUST air set ting to
re move stale air or smoke from the room, or it can be used
with the FRESH AIR setting to bring outside air into the
room, es pe cial ly in the spring and fall when cool ing isn’t
nec es sary.
The FRESH AIR and EXHAUST con trols are in the
up per air discharge area (see Figure 6, page 5). The cen ter
position of this control is the normal, or closed po si tion,
which re cir cu lates air for max i mum per for mance in the
cool ing mode.
NOTE: You may notice an odor when fi rst ac ti vat ing the
heat when the electric heat el e ment comes on. This is due
to dust burning off that may have gath ered on the coil
during the sum mer.
Temperature control
This dial is the thermostat. Turn it clock wise for cool er and
counterclockwise for warm er.
Money Saver® switch
This rocker switch can be depressed to either YES or NO.
In the YES position you will get the most eco nom i cal
operation. Both the fan and com pres sor will cy cle on and

the cooling mode. This control will only op er ate when the
unit is in cooling or heating mode. In the NO position, the
fan will run con stant ly as long as the unit is in the cooling
or heat ing mode.
Please Note: The YS09 is a 115 volt model and does not
provide adequate heat below 37°F (3°C). This prod uct is
designed for warm climate ap pli ca tions.

Removing and cleaning the filter / fresh air and exhaust feature
To remove, wash and replace filter and return air grille
Open the return air (RA) grille by grasping it at the top
outside edges and pulling towards you (See Figure 4). The
RA grille will stay open until it is detached or closed (it is
easier to completely detatch the grille before closing it).
To remove the RA grille, grasp it at the bottom and pull
towards you.
The fi lter is held in place by two spring clips (See Figure 4).
Push down on the clips, grasp the fi lter and pull towards you
to remove it for cleaning. Clean with warm water and a mild
detergent, rinse, dry completely and replace. Use caution
when removing the fi lter. The internal metal components
are sharp.
If the RA grille has been removed, pick up the grille by
supporting it from both sides near the bottom (See Figure 5,
Note 1). Lift return air grille and insert the grille's tabs into
the bottom slots of the discharge air plenum (See Figure 5,
Note 2). Snap the grille into place by pushing the grille up
and onto the unit's latches at the bottom (See Figure 5, Notes
3 and 4).
Fresh air and exhaust control
You r a ir con d i t io n er has the ability to bring fresh air into the
room and ex haust stale air out of the room. The con trol le ver
is found on the upper part of the unit (See Fig ure 6).

NOTE 2
SLOT
TO BRING IN FRESH AIR - Move the lever to the FRESH
AIR position which allows outside air to enter the room.
This is useful in fall and spring as a means of bringing in
fresh outside air when using FAN ONLY. It can also be
used in the summer with the com pres sor in the Cool ing
Mode if you wish. Normally, for most effi cient operation,
cooling is ac com plished with this control in the middle or
closed position.
TO EXHAUST INDOOR AIR - Move the lever to the
EXHAUST position. This will allow stale air to be expelled
to the outside of the dwelling. This is es pe cial ly handy
in the winter when indoor air tends to get stale, or after
a social gathering involving smokers, or to re move odors
after cooking.

Troubleshooting tips
920-003-10 (4-05)
Won’t cool?
If your air conditioner operates, but won’t cool; check to
see if the controls are properly set. Check the fi lter and
clean thoroughly if needed. Check to see if the vent door
is closed. Check to see if the chassis seal gasket is installed
(refer to installation instructions).
Won’t run?
Make sure the power cord is plugged in all the way. 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.
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) and
below 115°F (46°C), so it won’t cool a room if it is already
cool outside. If you want to cool a room in the winter, set
the unit to Fan Only and set the Fresh Air/Exhaust control
to Fresh Air. This will bring in a supply of outside air.
Condensation is normal
Air conditioners actually pump heat and humidity from
your room to the outside air. Hu mid i ty 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 insuffi cient airfl ow across
the coils, a dirty fi lter, cool, damp weath er, or all of these.
Set unit to Fan Only and the frost will disappear. Setting
the ther mo stat 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).
Cleaning your air conditioner
The decorative front and the cabinet can be cleaned with
warm water and a mild detergent. The indoor coil can be
va cuu med with a dusting att achment if it appear s to be di rt y.
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 thoroughly
before reinstalling the fi lter.
Heat pumps are different in the way they operate
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 coil temperature drops below 20°F (7°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
pu mp operat ion. I f you r unit is a 115 volt model (YS09
or YQ07), it is designed for use in warmer climates
and has no ele ctr ica l heat featur e, a nd wil l not prov ide
adequate heat below 37°F(3°C).
