depending on the air conditioner model.
Modify the TIMER Function
Navigate to the TIME menu to set the timer.
25
Remote Control - Refer to Figure 52 during operation description.
Getting Started - Install two (2) AAA batteries in the battery compartment
located on the back of the unit.
Operation - The remote control should be within 25 feet of the air conditioner
for operation (refer to Figure 52 for effectiveness). Press the power button
to turn the remote on. The remote will automatically power off after 15
seconds if the buttons are not being pressed. The remote must be on to
control the unit.
POWER Button - Turns remote and unit on and off.
SYSTEM Button - Allows the user to sequentially select the following:
AUTO, COOL, HEAT, and FAN ONLY operations. When the button is
pressed, the display indicates which mode has been selected via a display
message. Note that when the heating function is not available, the system
will automatically skip the HEAT mode.
FAN MODE Button - Selects between automatic (AUTO FAN) or
CONTINUOUS operation. In the AUTO FAN mode, the fan only turns on
and off when the compressor operates or the heat function is enabled.
NOTE: AUTO FAN is not available in the FAN ONLY Mode, the display
indicates CONTINUOUS. In the CONTINUOUS mode, fan speed
is determined by your selection on the FAN SPEED button.
FAN SPEED Button - Used to sequentially select new fan speed,
plus AUTO operation. When the FAN SPEED button is pressed, the
fan speed icon (triangle) changes to indicate the new speed level. Fan
speed automatically varies depending on the set temperature on the
control panel and the actual room temperature. For example, if there
is a big difference between your set temperature and the actual room
temperature, the system fan speed increases to HIGH. It remains at
this speed until the room temperature matches the set temperature.
UP and DOWN Arrows - Pressing either the 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.
Remote Effectiveness
Handheld Remote - Has an operating range of up to 25 ft. The infrared
remote control signal must have a clear path to transmit the command to
the air conditioning unit. The remote signal has some ability to “bounce”
off of walls and furniture similar to a television remote control. The diagram
below shows the typical operating range of the control in a standard room
with 8 ft high ceilings.

Airflow direction adjustment
The airow path may be adjusted to distribute air independently from the
left or right side of the discharge opening. Each of the banks of louvers can
be directed left, right, up, or down in order to achieve the most optimum
airow positioning.
To adjust airow direction, grab the lever in the center of the louver bank
and move it in the direction that you would like the air to be directed. Please
note that it is normal that airow may be stronger out of one side of the
louvers than the other.
Figure 53
FRR008
Airflow Selection and Adjustment
Fresh air and exhaust control
Your air conditioner has the ability to bring fresh air into the room or exhaust
stale air out of the room. The control slide is found on the upper part of the
unit (see Figure 53).
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.
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 spring or fall when indoor air tends to get stale,
or after a social gathering involving smokers, or to remove cooking odors.
BEST PERFORMANCE – Move the lever to the Re-Circulate Position.
This is the most efcient mode for cooling and heating.
27
IMPORTANT: Before you begin the actual installation of your air
conditioner, check your local electrical codes and the information below.
Your air conditioner must be connected to a power source with the same
alternating current (A.C.) voltage and amperage as marked on the name
plate located on the chassis. Only A.C. can be used. Direct Current (D.C.)
cannot be used.
CIRCUIT PROTECTION – Use on single outlet circuit only. An overloaded
circuit will invariably cause malfunction or failure of an air conditioner;
therefore, it is necessary that the electrical protection is adequate. Due
to momentary high current demand when the air conditioner starts, use a
“TIME DELAY” fuse or a HACR type circuit breaker. Consult your dealer or
power company if in doubt.
Refer to the electrical name plate located on the air conditioner chassis
(see Page 2) to determine the correct fuse or circuit breaker amperage for
your model (see Table 1 on Page 6 for electrical receptacle types).
The power cord has a plug with a grounding prong and a matching
receptacle is required.

STEP 5. Check the window sill and frame to be sure they are in
good condition and functioning.
STEP 6. CABINET MOUNTING – Raise the lower window
1
/4″ more than
the height of the cabinet. Carefully slide the cabinet through
the opening until the lower sill plate channel rests behind the
window sill and the top angle rests against the window (see
Figure 58). Center the cabinet within the opening. Drill three (3)
5
/32″ diameter pilot holes into window sill using the holes in the
cabinet sill plate as a guide. Install three (3) #12 x 2″ long screws
(Item 4) (see Figure 58).
STEP 7. OUTSIDE SUPPORT MOUNTING – Refer to Figures 57
and 58. Assemble the support brackets (Item 1) to the
bottom of the cabinet with four (4) 10-24 1″ long screws
(Item 2) and four 10-24 flat nuts (Item 3). Adjust the support
brackets, using a combination of the elongated holes of the
bracket and different hole locations in the cabinet, to bring
the bottom support bracket pads in contact with the wall. A
1″ x 4″ or 2″ x 4″ SPACER SHOULD BE USED BETWEEN THE
WALL AND SUPPORT THE BRACKETS WHEN INSTALLED
ON ALUMINUM OR VINYL SIDING. Drill
5
/32″ diameter pilot
holes and secure the brackets to the wall with two (2) 12A
x 2″ long screws (Item 4).
NOTE: DO NOT LEVEL the cabinet from front-to-back. Make sure
there is approximately a
3
/8″ to
1
/2″ slope (
1
/8 to
1
/4 bubble
on level) toward the outside of the house.
Adjust the support brackets to provide an inside-to-outside slope for
excess condensation drainage (refer to Standard Window Installation,
Figures 59 through 61). Tighten all screws.
Alternate support method A: If you have a deep window sill which
prevents you from mounting the brackets as shown in Figure 61, try the
following: Using the elongated holes and different hole locations in the
cabinet, set the placement of the bracket to support the unit’s weight
(Figure 62). Tighten all screws.
Alternate support method B: If the window ledge gap is narrow, try the
following. Bend the bracket end tab at. Cut the bracket in two (2) places
as shown in Figure 63. Bend the short piece so it will be vertical when
installed. Adjust the placement as required. Tighten all screws.
STEP 8. Measure and cut the wingboard panels (t with about
1
/8″
clearance) from the supplied Masonite (Item 8) to t the space
between the window side channels and cabinet (Figure 64).
Make sure you include the depth of the window channel.
NOTICE
For YOUR security and safety, YOU must
provide a means of preventing the upper
part of the window from opening.
STEP 9. To assemble the wingboard panels, push on the “J” type speed
nuts (Item 9) and spring steel clips (Item 10) (see Figure 65

STEP 10. INSTALL THE R1 INSULATION PANEL – To minimize air
leaks and ensure optimal insulation, install the included R1
insulation panel (14 in parts list) (see Figure 67A-C).
First, measure the width from one side of the cabinet/ sleeve
(covering the side angles where the wingboard was just secured)
to the end of the wingboard (see Figure 67A).
Next, cut the R1 insulation panel to the measured width and
remove protective cover, exposing adhesive on back panel
(see Figure 67B).
Last, evenly apply the adhesive side of the panel across the
entire height and width from side angle to wingboard panel
(see Figure 67C).
Repeat the steps above for the other wingboard panel.
STEP 11. INSTALL THE WINDOW SEALING GASKETS – Measure
and cut the dark foam window seal gasket (Item 12) and
install it between the upper glass panel and the top part of
the window sash (see Figure 67A).
STEP 12. Carefully team lift the chassis and set it into the cabinet. Slide
the chassis stopping approximately 3″ from full insertion. Insert
the chassis seal gasket (Item 13) one inch deep between the
chassis and the cabinet (see Figure 68) as shown on Page 37.
A paint stir stick or ruler might be helpful here. Begin inserting
the gasket at either bottom corner and go up the side, across the
top, and down the opposite side. Then push the chassis all the
way into the cabinet.
NOTE: If the chassis seal gasket is not installed or installed improperly,
the operation of the unit will be negatively affected. Operational
noise and outside noise will also amplied.

STEP 1. Follow Steps 1, 2, 3, and 4 of the “STANDARD WINDOW
INSTALLATION” instructions beginning on Page 29.
STEP 2. CABINET PREPARATION – Remove the sill plate from the
cabinet by removing two (2) nuts and screws (Figure 78).
Note that the chassis retainer is secured by a right side
nut and screw (Detail A, Figure 78). Bend the tabs of the
sill plate down into its channel at both ends of the plate or
cut them off (Detail B, Figure 78). Rotate the sill plate 180°
(end-to-end, Detail B, Figure 78) and reinstall. Reverse the
orientation of the nuts and screws, so that the head of the
screws are on the underside of cabinet facing up and the
nuts are on top (Detail C, Figure 78). Ensure that the chassis
retainer is reinstalled as shown in the detail.
STEP 3. WALL PREPARATION – The maximum wall thickness permissible
without special construction is determined by the model size to be
installed. Observe the maximum wall thickness shown in Figure 79.
Walls exceeding the maximum thickness shown in the chart should
be altered as shown in Figure 79.
STEP 4. CHECKING WIRING AND PLUMBING – Check for wiring
and plumbing inside and outside of the wall to be sure none will
be damaged when the cabinet framework is being constructed.
STEP 5. OPENING CONSTRUCTION – Depending upon size of unit
to be installed, lay out the hole dimensions per Table 3. Cut
and frame-in the opening to nished dimensions. If the wall
construction is a typical frame, or 2″ x 4″ studding with brick or
stone veneers, locate the opening next to one of the studs. For
masonry, concrete, or cinder block walls, locate an opening for
your convenience (see Figures 80, 81, and 82).

♦ Inspect and ensure that all components and accessories have been
installed properly and that they have not been damaged during the
installation progress.
♦ Check the condensate water drain(s) to ensure that they are
adequate for the removal of condensate water, and that they meet
the approval of the end user.
♦ Ensure that all installation instructions concerning clearances around
the unit have been adhered to. Check to ensure that the unit air lter,
indoor coil, and outdoor coil are free from any obstructions.
♦ Ensure that the circuit breaker(s) or fuse(s) and supply circuit wire
size have been sized correctly. If the unit was supplied with a power
supply cord, insure that it is stored properly.
♦ Ensure that the entire installation is in compliance with all applicable
national and local codes and ordinances having jurisdiction.
♦ Secure components and accessories, such as a decorative front cover.
♦ Start the unit and check for proper operation of all components in
each mode of operation.
♦ Instruct the owner or operator of the units operation, and the
manufacturer’s Routine Maintenance.
NOTE: A log for recording the dates of maintenance and/ or service is
recommended.
♦ Present the owner or operator of the equipment with the Installation &
Operation Manual, all accessory installation instructions, and the name,
address, and telephone number of the Authorized Friedrich Warranty
Service Company in the area for future reference if necessary.
Heat pumps operate differently
If your unit is a “KH”, 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 heating:
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 temperature drops below 37 °F (3 °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 (KHS10), it is designed for use in warmer climates and
does not have an electrical heat feature, and will not provide
adequate heat below 37 °F (2.8 °C).
Control Panel Battery Change Procedure
Remove the grille, by loosening four (4) captive screws (see Figure 84). In
the upper left corner, remove one (1) screw on the battery retaining door
(see Figure 85). Remove and replace the battery (CR2450). Reinstall
the battery retaining door. Align the grille guide pins then tighten the four
(4) captive screws. Before closing the grille panel door, check the lter.
Clean or replace it as necessary.

Figure 85
Final Inspection & Start-up Checklist
This is a warm weather appliance
Your air conditioner is designed to cool in warm weather when the outside
temperature is above 60 °F (15.6 °C) and below 115 °F (46.1 °C), so it won’t
cool a room if it is already cool outside. If you want to cool a room in the
spring or fall, select the FAN ONLY mode and set the Fresh Air/ Exhaust air
control to Fresh Air. This will bring in a supply of cooler outside air.
Condensation is normal
Air conditioners actually pump the heat and humidity from your room to the
outside. 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 these. Set the SYSTEM mode 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 units are designed to
operate as quietly as possible. An air conditioner mounted in a wall is
quieter than one mounted in a window. It is important to ensure that the
chassis seal gasket (Item 13) is properly installed (refer to the Installation
Instructions).
1. USE HAND TOOLS WHEN INSTALLING
AND REMOVING FRONT PANEL.
DO NOT OVERTIGHTEN SCREWS.
2. DISCONNECT POWER AND FOLLOW
ALL LABELED WARNINGS WHEN
FRONT PANEL IS REMOVED.
45
To ensure proper unit operation, the air lter should be cleaned at least
monthly, and more frequently if conditions warrant. The unit must be turned
off before the lter is cleaned.
To Remove, Wash and Replace Filter
Lower front panel (Figure 2). Use the handle on the lter to ex lter up and
out of retainer. Remove lter from unit (Figure 3). Clean the lter monthly or
more frequently if needed. Refer to the Accessories section for lter options.
Coils & Chassis
NOTE: Do not use a caustic cleaning agent on coils or base pan. Use a
biodegradable cleaning agent and degreaser. The use of harsh
cleaning materials may lead to deterioration of the aluminum
ns or the coil end plates.
The indoor coil and outdoor coils and base pan should be inspected
periodically (annually or semi-annually) and cleaned of all debris (lint,
dirt, leaves, paper, etc.) as necessary. Under extreme conditions, more
frequent cleaning may be required. Clean the coils and base pan with a
soft brush and compressed air or vacuum. A pressure washer may also be
used; however, you must be careful not to bend the aluminum n pack. Use
a sweeping up and down motion in the direction of the vertical aluminum n
pack when pressure cleaning coils.
NOTE: It is extremely important to insure that none of the electrical
and/ or electronic parts of the unit get wet. Be sure to cover all
electrical components to protect them from water or spray.
Decorative Front
Use a damp (not wet) cloth when cleaning the control area to prevent water
from entering the unit, and possibly damaging the electronic control.
The decorative front and the cabinet can be cleaned with warm water and a
mild liquid detergent. Do NOT use solvents or hydrocarbon based cleaners
such as acetone, naphtha, gasoline, benzene, etc.
The indoor coil can be vacuumed with a dusting attachment if it appears
to be dirty. DO NOT BEND FINS. 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 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 the lter thoroughly before
reinstalling. Use caution, the coil surface can be sharp.
Fan Motor & Compressor
The fan motor & compressor are permanently lubricated and require no
additional lubrication.
Wall Sleeve
Inspect the inside of the wall sleeve and drain system periodically (annually
or semi-annually) and clean as required. Under extreme conditions, more
frequent cleaning may be necessary. Clean both of these areas with an
antibacterial and antifungal cleaner. Rinse both items thoroughly with water
and ensure that the drain outlets are operating correctly. Check the sealant
around the sleeve and reseal areas as needed.

Troubleshooting Tips
47
COMPLAINT CAUSE SOLUTION
Unit Does Not Cool/ Heat Room
Sufciently, or Cycles On And Off
Too Frequently (continued).
• The outside temperature is below 60 °F
(16 °C).
• Do not try to operate your air conditioner in the
cooling mode when the outside temperature is below
60 °F (16 °C). The unit will not cool properly, and the
unit may be damaged.
• The digital control is set to fan cycling mode.
• Since the fan does not circulate the room air
continuously at this setting, the room air does not
mix as well and hot (or cold) spots may result. Using
the continuous fan setting is recommended to obtain
optimum comfort levels.
• The air conditioner has insufcient cooling
capacity to match the heat gain of the room.
• Check the cooling capacity of your unit to ensure it
is properly sized for the room in which it is installed.
Room air conditioners are not designed to cool
multiple rooms.
• The air conditioner has insufcient heating
capacity to match the heat loss of the room.
• Check the heating capacity of your unit. Air conditioners
are sized to meet the cooling load, and heater size
is then selected to meet the heating load. In extreme
northern climates, room air conditioners may not be able
to be used as a primary source of heat.
Unit Runs Too Much.
• This may be due to an excessive heat load
in the room.
• If there are heat producing appliances in use in the
room, or if the room is heavily occupied, the unit will
need to run longer to remove the additional heat.
• It may also be due to an improperly sized unit.
• Be sure to use exhaust vent fans while cooking or
bathing and, if possible, try not to use heat producing
appliances during the hottest part of the day.
• This may be normal for higher efciency
(EER) air conditioners.
• The use of higher efciency components in your new
air conditioner may result in the unit running longer
than you feel it should. This may be more apparent, if
it replaced an older, less efcient, model. The actual
energy usage, however, will be signicantly less
when compared to older models.
• You may notice that the discharge air
temperature of your new air conditioner
may not seem as cold as you may be
accustomed to from older units. This
does not; however, indicate a reduction
in the cooling capacity of the unit.
• The energy efciency ratio (EER) and cooling
capacity rating (Btu/ h) listed on the unit’s rating
plate are both agency certied.
