WARNING: Beforeoperatingyourunit
Make sure the wiring isadequate 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 Figure 1.
DO NOT use an extension cord.
The cord provided will carry the proper amount of electrical
power to the unit; an extension cord will not.

This insures proper grounding. If you have a two-prong
receptacle you will need to have the circuit replaced by
a certified electrician with a grounded circuit that meets
all national and local codes and ordinances. Under no cir-
cumstances should you remove the ground prong from the
plug. You must use the three-prong plug furnished with
the air conditioner.

Keep the filter clean
Make sure that your air conditioner is always in top per-
forming condition by cleaning the filter regularly. Instruc-
tions for removing and cleaning the filter can be found on
page 5 and 6.
Providegoodairflow
Make sure that the airflow to and from the unit is clear. Your
air conditioner puts the air out at the top of the unit, and
takes in air at the bottom. Airflow is critical to good opera-
tion. It isjust as important on the outside of the building that
the airflow around the unit exterior is not blocked.
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 efficiently. Using drapes or blinds on
the sunny side of the dwelling will also add to your unit's
efficiency.
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.

Tostart unit
If your air conditioner is installed and plugged into a proper
receptacle, it is ready to go.
Functioncontrol
This dial control allows you to select cooling or heating 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 response.
Turn to MED COOL or MED HEAT to maintain a desired
temperature.
Turn to LO COOL or LO HEAT for nighttime use, or
when demand is low.
T W I N T E M P ®
The FAN ONLY setting will circulate air in the room
without the compressor coming on. The FAN ONLY
setting can also be used with the EXHAUST air setting to
remove stale air or smoke from the room, or it can be used
with the FRESH AIR setting to bring outside air into the
room, especially in the spring and fall when cooling isn't
necessary.
The FRESH AIR and EXHAUST controls are in the
upper air discharge area (see Figure 5, page 5). The center
position of this control is the normal, or closed position,
which recirculates air for maximum performance in the
cooling mode.
NOTE:
You may notice an odor when first activating the heat
when the electric heat element comes on. This is due to
dust burning off that may have gathered on the coil during
the summer.
Temperaturecontrol
This dial is the thermostat. Turn it clockwise for cooler and
counterclockwise for warmer.

MoneySaver®switch
This rocker switch can be depressed to either YES or NO.
In the YES position you will get the most economical
operation. Both the fan and compressor will cycle on and
off together, maintaining the selected temperature at a more
constant level and reducing the humidity more efficiently in
the cooling mode. This control will only operate when the
unit is in cooling or heating mode. In the NO position, the
fan will run constantly as long as the unit is in the cooling
or heating mode.
Please Note: The YS09 is a 115 volt model and does not
provide adequate heat below 37°F (3°C). This product is
designed for warm climate applications.

Howto operateyourFriedrichroomair conditioner(Continued)
To remove, wash and replace filter
Open the return air (RA) grille by grasping it at the top
outside edges and pulling towards you (see figure 3). The
RA grille will stay open until it is detached or closed. If
you need to remove the RA grille, grasp it at the bottom
and pull towards you.
The filter is held in place by two spring clips (see figure 4).
Push down on the clips, grasp the filter 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 filter. The internal metal
components are sharp.
Figure 3
If the RA grille has not been completely detached, close it
by grasping it at the top outside edges and pushing it towards
the unit until it snaps shut.
If the RA grille has been removed, reposition it bottom
first, while lining up the control panel opening with the
control panel itself (see figure 3). Once it is lined up, push
in at the bottom of the RA grille until you hear it snap into
place. Now close it by grasping the tip outside edges and
pushing it towards the unit until it snaps shut.
Fresh air and exhaust control
Your air conditioner has the ability to bring fresh air into
the room and exhaust stale air out of the room. The control
lever is found on the upper part of the unit (see Figure 5).
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 unit in the Cooling
Mode if you wish. Normally, for most efficient operation,
cooling is accomplished with this control in the middle or
closed position.
Figure 5
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 especially handy
in the winter when indoor air tends to get stale, or after
a social gathering involving smokers, or to remove odors
after cooking.

ModelYO.07
This model has a different control panel (Figure 6) from the
TWINTEMP _ _/_0_
larger TwinTemp® units, but it performs equally well. This
model is designed for use in warmer climates; therefore it
does not have back-up electric heat and will not provide
adequate heating below an outdoor ambient temperature
of 37°F (3° C).

Heatpumpsaredifferentinthewaytheyoperate
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.
Troubleshootingtips
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.
Won't run?
Make sure the power cord is plugged in all the way. Check
for a bad fuse or a tripped breaker. This guide shows the
proper fuse size on page 3.
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.
Condensationisnormal
Air conditioners actually pump heat and humidity from
your room to the outside air. 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.
.
If the outdoor coil temperature drops below 20°F (-
7°C), your heat pump will automatically turn on the
electric resistance 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 (YS09
or 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).
Frosting
This usually occurs because of insufficient airflow across
the coils, a dirty filter, cool damp weather, 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 conditioner mounted
in a wall is quieter than one mounted in a window.
Cleaningyourair conditioner
The decorative front and the cabinet can be cleaned with
warm water and a mild liquid detergent. The indoor coil
can be vacuumed with a dusting attachment 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.
