C. INSTALLATION OF THE UNIT
C.1 Pre-Installation Checkpoints
Before attempting any installation, carefully consider the
following points:
• Clearances and provision for servicing. Install this unit
in accordance with local and national standards. Any
and all work must be done by authorized personnel.
• 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 Table E.1 to determine the
correct fuse or circuit breaker amperage for your model.
• The power cord has a plug with a grounding prong and a
matching receptacle is required.

Falling Object Hazard
Not following Installation Instructions
for mounting your air conditioner can
result in property damage, injury, or
death.
The following instructions apply to wood, masonry, brick, concrete or cinder
block wall construction.
STEP 3. CABINET PREPARATION – Remove the sill plate from the cabinet
by removing two (2) nuts and screws (Figure C.5.4). Note that the
chassis retainer is secured by a right side nut and screw (Figure
C.5.4 Detail 1). Bend the tabs of the sill plate down into its channel
at both ends of the plate or cut them off (Figure C.5.4 Detail 2).
Rotate the sill plate 180° (end-to-end, Figure C.5.4 Detail 2) 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 (Figure C.5.4 Detail 3). Ensure that the chassis
retainer is reinstalled as shown in the detail.
STEP 4. 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 C.5.6 Walls exceeding the
maximum thickness shown in the chart should be altered as shown in Figure
C.5.6
STEP 5. 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 6. 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 C.5.7,
C.5.8, C.5.9).

• 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.
J.2 Air Flow Selection and Adjustment
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.
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.

J. STARTUP AND OPERATION
J.5 Start-up
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 insufficient airflow across the coils, a
dirty filter, 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).
NOTICE
This unit is certified to operate in cooling mode under these
maximum conditions. Any operation beyond these conditions may
result in intermittent operation.
Indoor temperature: 90 °F (45% relative humidity)
Outdoor temperature: 110 °F (25% relative humidity)
If unit is heat pump equipped, it is certified to operate in heating
mode under these maximum conditions. Any operation beyond these
conditions may result in intermittent operation.
Indoor temperature: 80 °F (humidity does not affect operation)
Outdoor temperature: 70 °F (60% relative humidity)
J.4 Remote Control Operation
Remote Control - Refer to Figure J.4.1 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. 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.

COMPLAINT CAUSE SOLUTION
Unit does not operate.
• The unit is turned to the off position, or the
thermostat is satised.
• Turn the unit to the on position and raise or lower temperature
setting (as appropriate) to call for operation.
• The LCDI power cord is unplugged.
• Plug into a properly grounded 3 prong receptacle. See “Electrical
Rating Tables” on Page 6 for the proper receptacle type for your
unit.
• The LCDI power cord has tripped (Reset
button has popped out).
• Press and release RESET (Listen for click. Reset button latches
and remains in.) to resume operation.
• The circuit breaker has tripped or the
supply circuit fuse has blown.
• Reset the circuit breaker, or replace the fuse as applicable. If
the problem continues, contact a licensed electrician.
• There has been a local power failure.
• The unit will resume normal operation once power has been
restored.
Unit Trips Circuit Breaker or
Blows Fuses.
• Other appliances are being used on the
same circuit.
• The unit requires a dedicated outlet circuit, not shared with other
appliances.
• An extension cord is being used.
• Do NOT use an extension cord with this or any other air condition-
er.
• The circuit breaker or time-delay fuse is
not of the proper rating.
• Replace with a circuit breaker or time-delay fuse of the proper
rating. See Table E.1 for the proper circuit breaker/ fuse rating for
your unit. If the problem continues, contact a licensed electrician.
LCDI Power Cord Trips
(Reset Button Pops Out).
• The LCDI power cord can trip (Reset
button pops out) due to disturbances on
your power supply line.
• Press and release RESET (Listen for click. Reset button latches
and remains in.) to resume normal operation.
• Electrical overload, overheating, or cord
pinching can trip (Reset button pops out)
the LCDI power cord.
• Once the problem has been determined and corrected, press
and release RESET (Listen for click. Reset button latches
and remains in.) to resume normal operation.
NOTE: A damaged power supply cord must be replaced with a new power supply cord obtained from the product manu-
facturer and must not be repaired. The power cord must be replaced by trained service personnel.
Unit Does Not Cool/ Heat Room
Sufciently, or Cycles On And Off
Too Frequently.
• The return/ discharge air grille is blocked.
• Ensure that the return and/ or discharge air paths are not blocked
by curtains, blinds, furniture, etc.
• Windows or doors to the outside are open. • Ensure that all windows and doors are closed.
• The temperature is not set at a cool
enough/ warm enough setting.
• Adjust the Temperature control to a cooler or warmer setting as
necessary.
• The lter is dirty or obstructed. • Clean the lter, (see Routine Maintenance), or remove obstruction.
• The indoor coil or outdoor coil is dirty or
obstructed.
• Clean the coils, (see Routine Maintenance), or remove obstruction.
• There is excessive heat or moisture
(cooking, showers, etc.) in the room.
• 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.
• The temperature of the room you are
trying to cool is extremely hot.
• Allow additional time for the air conditioner to cool off a very hot
room.

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.
