Control Panel Operation

Let’s check out how to control your air conditioner. On the control panel,
ju st t o the lef t o f th e POW ER
control panel function buttons and mode icons can be viewed in Figure 8.

Power On – Press the
power button will illuminate to indicate the power is on. The backlight on
the power switch will automatically dim to 20% intensity after 15 seconds
of inactivity. The remote control can also be used to turn power ON / OFF
(See Remote Control).

Display – The display is a high effi ciency LCD with a built-in white back
light. The back light has an automatic two (2) step dim function. After 15
seconds of inactivity, the display dims to 20% intensity. After an additional
120 seconds, the display switches off. Touching buttons will automatically
bring the display to full brightness.

There are four control push buttons on each side of the display.

SYSTEM Button – Allows the user to sequentially select,

, HEAT , and FAN ONLY operation. Press the
the display advances to the next mode. A new icon appears. At the same
time, the mode displays for two (2) seconds, then returns the display to
the temperature set point for modes other than FAN. Note that when the
heating function is not available, the system will automatically skip the
HEAT

SPEED

display window, plus a fan speed icon (triangle) changes to indicate the
new speed level when auto is selected. Fan speed automatically varies
depending on the set temperature on the control panel and the actual
room temperature. Let me explain. Say for example you’re working in
your garage and you need to open the big door for several minutes. The
air conditioner will sense a wide difference between the set temperature
and the actual room temperature when this occurs the system fan speed
increases to MAX. The fan speed decreases (in step) as the temperature
difference decreases. When the set point temperature is reached the FAN
speed returns to the original setting.

designed to keep the interior space above freezing by energizing the
electric heater anytime the indoor room temperature falls to 40° F (4° C).
With the freeze protection feature turned on, when the unit senses the
indoor temperature fall to 40° F (4° C) the unit will run the heater and high

Temperature Offset – In some cases the built in thermostat on the unit
may not display the temperature as it is felt in the room. This can be caused
by many things including the size of the unit, the heat load on the room or
other factors. Friedrich allows you to select the appropriate temperature
offset to make the temperature readout as accurate as possible for your
application. In many cases the factory 0° F (-18° C) offset will provide
an accurate temperature readout. To change the offset follow these

Remote Control Operation

Remote Control – Refer to Figures 11 and 12 during operation description.

Getting Started – Install two (2) AA A 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 10 for effectiveness). Press the

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,

your garage and you need to open the big door for several minutes. Since
there is a big difference between your set temperature and the actual room
temperature the system fan speed increases to MAX. It remains at this
speed until the room temperature matches the set temperature.

Airflow Selection and Adjustment

Air flow direction adjustment

The airfl ow 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 d irec ted l eft, righ t, up or d own i n or der t o ac hiev e th e mos t op timu m
airfl ow positioning.

To a djus t ai rfl ow 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 airfl ow may be stronger out of one side of the
louvers than the other.

TO BRING IN FRESH AIR – Move the lever to the Fresh Air
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.

Fresh air and exhaust control

Your air con di tion er has the ability to bring fresh air into the room or ex haust
stale air out of the room. The con trol slide is found on the upper part of
the unit (See Fig ure 13).

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 spring or fall when indoor air tends to get
stale, or after a social gathering involving smokers, or to re move cooking
odors.

BEST PERFORMANCE – Move the lever to the Re -Circulate Position

. This is the most effi cient mode for cooling and heating.

Installation Instructions

READ THIS FIRST! Electrical Requirements

WARNING

Electrical Shock Hazard

Make sure your electrical receptacle has the
same configuration as your air conditioner’s
plug. If different, consult a Licensed Electrician.

Do not use plug adapters.
Do not use an extension cord.
Do not remove ground prong.

Always plug into a grounded 3 prong oulet.
Failure to follow these instructions can result in
death, fire, or electrical shock.

IMPORTANT: Before you begin the actual installation of your air
conditioner, check 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.

The following instructions are for standard chassis model groups
distinguished by the fi rst two letters of the model designations and cabinet
sizes listed in Table 3.

STEP 1. Follow steps 1, 2, 3, and 4 of the "STANDARD WINDOW

INSTALLATION" instructions beginning on page 20.

STEP 2. CABINET PREPARATION – Remove the sill plate from the

cabinet by removing two (4) nuts and screws (Figure 38).
Note that the chassis retainer is secured by a right side nut
and screw (Detail A, Figure 38). Bend the tabs of the sill plate
down into its channel at both ends of the plate or cut them off
(Detail B, Figure 38) Rotate the sill plate 180° (end-to-end,
Detail B, Figure 38) 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 38). Ensure that the chassis retainer is reinstalled
as shown in the detail.

NOTICE

The outside cabinet condenser air intake louvers
MUST NOT BE BLOCKED by extra thick walls.

STEP 3. WA LL PREPAR ATI ON – 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 39. Walls exceeding the maximum
thickness shown in the chart, should be altered as shown in
Figure 39.

Programmable Thermostat

Your unit features an advanced 7 day programmable thermostat feature that
can be used to turn the unit on or off or even change modes and maintain
temperatures throughout the day.

Factory settings are shown in addendum 1 (Schedule Table with Energy
Saving Values). These values can be changed by following the procedures
in the preceding paragraphs. Basic options are: Four (4) day groups.

1. Monday through Friday.

2. Saturday and Sunday only.

3. Monday through Sunday.

4. Individual days (Mon thru Sun).

Each of the day groups have four (4) time periods: WAKE (06:00), AWAY
(08:00), RETURN (18:00), and NIGHT (22:00).

The start time for each of the time periods can be changed. In addition,
each time period can have its own temperature and fan mode.

For example, let’s say you are in a cool climate region. You leave for work
at 08:00 and return home around 18:30. You can set the temperature lower
while you are away from your home. At 18:00, you set the temperature
higher for the RETURN period so the room is nice and comfortable when
you arrive.

Final Inspection & Start-up Checklist

 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 fi 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 "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 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 (YS10),
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

Re mov e the gril le, by l oose nin g fou r (4) c apt ive s crew s (S ee F igur e 44). In
the upper left corner, remove one (1) screw on the battery retaining door
(See Figure 45). 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 fi lter.
Clean or replace it as necessary.

Figure 44

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

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 14) is properly installed (refer to installation
instructions).

Routine Maintenance

To ensure proper unit operation, the air fi lters should be cleaned at least
mo nthl y, a nd m ore f requ ent ly if c ondi ti ons war ra nt. The u nit must be t ur ned
off before the fi lters are cleaned.

WARNING

Electrical Shock Hazard

Make sure your electrical receptacle has the
same configuration as your air conditioner’s
plug. If different, consult a Licensed Electrician.

Do not use plug adapters.
Do not use an extension cord.
Do not remove ground prong.

Always plug into a grounded 3 prong oulet.

To Remove, Wash and Replace Filter

Lower front panel (See Figure 2). Use handle on fi lter to fl ex fi lter up and
out of retainer. Remove fi lter from unit (See Fi gure 3). Clean fi lter monthly
or more frequently if needed. Refer to accessories section for fi lter options.

Coils & Chassis

NOTE: Do not use a caustic coil cleaning agent on coils or base pan.

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 fi n pack. Use a
sweeping up and down motion in the direction of the vertical aluminum fi n
pack when pressure cleaning coils.

NOTE: It is extremely important to insure that none of the electrical

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 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 the fi 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.

Use a biodegradable cleaning agent and degreaser. The use
of harsh cleaning materials may lead to deterioration of the
aluminum fi ns or the coil end plates.

and/or electronic parts of the unit get wet. Be sure to cover all
electrical components to protect them from water or spray.

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.

● The outside temperature is below
60° F (16° C).

● The digital control is set to fan
cycling mode.

● The air conditioner has insuffi cient
cooling capacity to match the heat
gain of the room.

● The air conditioner has insuffi cient
heating capacity to match the heat
loss of the room.

● This may be due to an excessive
heat load in the room.

● It may also be due to an improperly
sized unit.

● This may be normal for higher
effi ciency (EER) air conditioners.

● 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.

● 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.

● 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.

● 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.

● 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.

● 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.

● 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 use of higher effi ciency 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 effi cient, model. The actual energy
usage, however, will be signifi cantly less when
compared to older models.

● The energy effi ciency ratio (EER) and cooling
capacity rating (Btu/h) listed on the unit’s rating
plate are both agency certifi ed.
