Control Panel Operation

Let's check out how to control your air conditioner. On the control panel, just to the left of the POWER is a liquid crystal display (LCD). All of the control panel function buttons and mode icons can be viewed in Figure 8.

Power On – Press the ⏻ button to turn on the air conditioner. 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 efficiency 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, AUTO Cool *, HEAT and FAN ONLY operation. Press the button and 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 and AUTO.

NOTE: After the compressor stops the fan will continue to operate for 30 seconds.

FAN MODE Button – Selects between automatic AUTO or CONTINUOUS operation. In the AUTO, the fan only turns on and off when the compressor operates or the heat function is enabled.

In the FAN ONLY Mode, AUTO is not available. The display indicates CONTINUOUS. In the CONTINUOUS speed is determined by your selection on the AUTO SPEED.

FAN SPEED Button – Used to sequentially select between fan speeds. Depending on your model, you can select between LOW, MED, HIGH, and MAX and AUTO. Max setting not on SL, EL, YL or cool plus models). When the FAN SPEED button is pressed, the fan speed is temporarily displayed in the 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.

SCHEDULE Button – The 📋 button turns the schedule function on and off. The current day of the week is indicated as a dot underneath the day symbol. Pressing the 📋 button a second time turns the schedule function off. The schedule function comes preprogrammed with recommended energy savings values (Addendum 1). The values may be changed through the schedule program function (See Programmable Thermostat).

UP and DOWN arrows – Pressing either ▲(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.

BACK Button – This button is used after a menu item has been selected. It takes the user back to the previous menu level.

DISPLAY/ENTER Button – This button is used in conjunction with User menu and Maintenance Mode operation to select items. This button may also be used alternately to display the ROOM TEMPERATURE and TIME. If the display is left inactive for 10 seconds it will reset to the TEMPERATURE SET POINT.

Alerts – The control system has five (5) customer alerts.

CHECK FILTER – When the filter needs to be checked, an icon appears on screen. The word “RESET” acts next to the .nottu PACK. The CHECK FILTER alert is issued when the fan run time is greater than 500 hours. This alert may be reset by the user (Refer to Special Functions, Filter Reset).

Maintenance Required – When maintenance is required, a service icon 📁 appears on screen. This icon will not be dismissed until maintenance has been performed. If the service icon 📁 flashes, maintenance is required and must only be performed by qualified service personnel. When the icon 📁 is on standby the system has sensed an abnormal condition. For example: The air in/out louvres may be blocked. Once proper air flow is established the service icon 📁 goes away.

Wait – The WAIT icon 📁 illuminates when the compressor lockout is active. Whenever the compressor shuts off, system pressures must be allowed to equalize. At this time, an internal timer begins a count-down from up to 240 seconds. If a demand for heat or cool occurs during this count-down the WAIT icon 📁 displays letting you know that the compressor will not operate until the count-down has completed. This timer prevents damage to the unit if it tries to start too quickly after it stops running. Normally the WAIT icon 📁 is off. Once the timer has cleared, the air conditioner will heat or cool based on the temperature setting. Electric heat is not affected by this timer.

Protection Alert (Freeze) – If the room freeze protection is active, the display indicates this by showing Room Freeze Protection "FRZ". Once the condition is satisfied, the "FRZ" display is removed. If the room temperature is less than 40^ F ( 4^ C), and the air conditioner is equipped with electric heat, the room freeze protection will activate. The air conditioner will run high fan and electric heat until the room temperature reaches 46^ F ( 8^ C). Pressing the BACK button delays the freeze protection function for five (5) minutes.

Low Battery – When the battery is low a warning display BATT will be inserted before other messages such as "COOL". If the Low Battery BATT alert is on, the battery in the control unit must be changed. Refer to the changing the battery procedure. Once the battery is changed, the alert message will go off. Refer to Troubleshooting Tips. Under normal conditions the battery life should be greater than 7 years.

Remote Control Operation

Remote Control – Refer to Figures 11 and 12 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 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, AUTO Cool HEAT and FAN ONLY operation. 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 and AUTO modes.

FAN MODE Button – Selects between automatic (AUTO) or CONTINUOUS operation. In the AUTO mode, the fan only turns on and off when the compressor operates or the heat function is enabled.

NOTE: AUTO 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 is temporarily displayed in the display window, plus a 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. Let me explain. Say for example you're working in 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.

SCHEDULE Button – The button turns the schedule function on and off. Pressing the button a second time turns the schedule function off. Only the schedule icon will be displayed.

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

Hand Held 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.

The airflow 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 airflow positioning.

To adjust airflow 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 airflow 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 13).

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 efficient 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 first two letters of the model designations and cabinet sizes listed in Table 3.

CAUTION

Remove Shipping Blocks

Prior to operating the unit remove the foam shipping blocks.

Failure to do so may result in damage to the unit which is not covered by the manufacturer's warranty!

STEP 5. Check the window sill and frame to be sure they are in good condition and firmly anchored to the wall. Repair if necessary.

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 18). 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 18).

STEP 7. OUTSIDE SUPPORT MOUNTING – Refer to Figures 19 and 20. 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 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 19 through 23). Tighten all screws.

Alternate support method A: If you have a wide window sill which prevents you from mounting the brackets as shown in Figure 22, 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 22). Tighten all screws.

Alternate support method B: If the window ledge gap is narrow, try the following. Bend the bracket end tab flat. Cut the bracket in two (2) places as shown in Figure 23. 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 (fit with about 1/8" clearance) from the supplied Masonite (Item 8) to fit the space between the window side channels and cabinet. (Figure 24). 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 Figures 25) on page 26. Secure each panel with two (2) screws (Item 11).

Programmable Thermostat

Your unit's digital control 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 filter, 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.

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

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

Remove the grille, by loosening four (4) captive screws (See Figure 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 filter. Clean or replace it as necessary.

Routine Maintenance

To ensure proper unit operation, the air filters should be cleaned at least monthly, and more frequently if conditions warrant. The unit must be turned off before the filters 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. Failure to follow these instructions can result in death, fire, or electrical shock.

To Remove, Wash and Replace Filter

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

Coils & Chassis

NOTE: Do not use a caustic coil 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 fins 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 fin pack. Use a sweeping up and down motion in the direction of the vertical aluminum fin 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 filter 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 filter 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

COMPLAINT CAUSE SOLUTION
Unit does not operate.	The unit is turned to the off position, or the thermostat is satisfied.	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 pg. 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 conditioner.
	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 “Electrical Rating Tables” on pg. 6 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 manufacturer and must not be repaired.
Unit Does Not Cool/Heat Room Sufficiently, 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 filter is dirty or obstructed.	Clean the filter, (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.
Unit Does Not Cool/Heat Room Sufficiently, 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 insufficient 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 insufficient 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 efficiency (EER) air conditioners.	The use of higher efficiency 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 efficient, model. The actual energy usage, however, will be significantly 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 efficiency ratio (EER) and cooling capacity rating (Btu/h) listed on the unit's rating plate are both agency certified.
