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 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.

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 certied 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 furnished with
the air conditioner.

For the best cooling performance and highest energy efficiency
Keep the filter clean
Make sure that your air conditioner is always in top
performing condition by cleaning the filter regularly.
Instructions for removing and cleaning the lter can be
found on page 5.
Provide good airflow
Make sure the airow 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. Airow is critical to good operation.
It is just as important on the outside of the building that the
airow around the unit exterior is not blocked.
Unit placement
If your air conditioner can be placed in a window or wall that
is shaded by a tree or another building, the unit will operate
even more efciently. Using drapes or blinds on the sunny
side of the dwelling will also add to your unit’s efciency.
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.

How to operate your Friedrich room air conditioner
To start unit
If your air conditioner is installed and plugged into a
properly grounded receptacle, it is ready to operate.
Mode control
This dial allows you to select cooling at three different
speeds, as well as Fan Only.
Off- turns the unit off.
Hi Cool- for quick cooling.
Med Cool- to maintain a desired temperature.
Lo Cool- for night time use, or when demand is low.
Fan Only- will circulate air in the room without the
compressor coming on.
This 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. This is especially useful in the spring and fall
when cooling may not be necessary. The FRESH AIR and
EXHAUST controls are in the upper air discharge area.
The center position of this control is the normal, or closed
position, which recirculates air for maximum performance
in the cooling mode.
Figure 2
Temperature control
This dial is the thermostat. Turn it clockwise for cooler
temperature and counterclockwise for warmer.
MoneySaver® switch
This rocker switch can be depressed to either Yes or No.
The Yes position provide 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 efciently. This
control will only operate when the unit is in a Cool mode.
In the No position, the fan will run constantly as long as the
unit is in the cooling mode.

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 gure 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 lter is held in place by two spring clips (see gure 4).
Push down on the clips, grasp the 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 lter. The internal metal
components are sharp.
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 rst,
while lining up the control panel opening with the control
panel itself (see gure 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 top outside edges and pushing
it towards the unit until it snaps shut.

Figure 3
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 compressor in the Cooling
Mode if you wish. Normally, for most efcient operation,
cooling is accomplished 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 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.

Troubleshooting tips
Won’t cool?
If your air conditioner operates, but won’t cool; check to see
if the controls are properly set. Check the lter 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) 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. 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.
Frosting
This usually occurs because of insufcient airow across
the coils, a dirty lter, 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. Friedrich
QuietMasters® operate as quietly as possible. An air
conditioner mounted in a wall is quieter than one mounted
in a window. If mounted in a window, the window mount kit
provided with QuietMaster® models will reduce operating
sound levels, when properly installed.
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
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.
