WELCOME to years of economical comfort

Your new Friedrich Room Air Conditioner has been carefully engineered and manufactured to give you many years of dependable, efficient operation, keeping your room at a comfortable temperature and humidity level. Many extra features have been built into your Friedrich Room Air Conditioner to assure quiet operation, greatest circulation of cool, dry air, most flexible selection of function controls, and high economy of operation.

There are many things you can do in and around your home to save more money - and even increase the efficiency and long life of your Friedrich unit. Here are a few examples:

1.How to Set Thermostat: When you first turn on your air conditioner, select the highest fan speed and set the thermostat to its coldest position to cool the room. When the desired temperature is reached, turn the thermostat control toward "warmer" until the compressor goes off. The thermostat will then cause the compressor to go on and off to maintain this selected temperature. You can adjust the fan speed for optimum air circulation.

2.Do not block the flow of air to and from the unit - make sure the louvers are directed to give even distribution of air throughout the room. Caution: If air is obstructed and/or deflected back into the air conditioner, this may cause the unit to cycle on and off rapidly, which could damage your unit.

3.Adequate insulation - walls, ceilings, and below floors - can save up to 50% of the cost of cooling in most areas of the country.

4.Caulking: in well insulated homes, air leaks around doors, windows, lighting and plumbing fixtures can account for as much as 30% of the load on heating and cooling systems. See that all these areas are well caulked.

5.Install weather stripping (metal is preferable to felt) around exterior doors and windows.

6.Have a fireplace? Be sure the damper is closed during air conditioner operation.

7.When it’s time to reroof or repaint the outside of your home, choose light colors. They reflect heat instead of absorbing it.

8.Shade your outside walls (especially on the west) from the direct sun; most importantly, shade the unit itself Trees and shrubs provide natural shading, but make sure they don’t block the air flow around the unit. If natural shade isn’t present, awnings are the best solution for shading the unit and the windows. Also, avoid areas where too much dust or pollen would be drawn into the air conditioner.

9.Inside the house, use blinds, screens, or drapes on windows exposed to the sun. They will reduce your cooling needs. (Lined or insulated draperies will also help cut heating costs in winter).

10.Make sure your attic area is properly vented. In addition, consider installing turbine or power ventilators to help remove hot air from your attic.

11.Keep your Friedrich unit clean. Use a vacuum cleaner attachment for accessible parts, but take care not to damage them. Clean the reusable filter at least twice a month.

12.Set the thermostat at a higher temperature - save 5% in energy usage for each degree of temperature over 72°F.

These are the most important suggestions for saving money on cooling costs. Some, however, may not be applicable to your house or area. Check with your local utility company for more specialized information.

How to operate your Friedrich room air conditioner

To start unit

If your air conditioner is installed and plugged into a proper receptacle, it is ready to go. The first time the unit is started, the compressor will delay for three minutes. See Automatic Component Protection on the following page.

1Touch the Power button once. The unit will automatically be inCool mode with the temperature set at 75°F (24°C) and the fan speed at F1, the sleep setting.

To set mode of operation

When you first turn the unit on, it will be in the Cool mode with constant fan.

2On WS cool-onlymodels, touch theMode buton once to activate theMoneySaver® (WS models only. See item 14 for Money Saver instructions on WY/WE models).

MoneySaver® is a feature that cycles the fan with the compressor so that the fan does not run all the time. This saves energy and improves dehumidification. MoneySaver® will also run to test the temperature if the off cycle is too long. Or you may prefer constant fan for more air movement. (To return to constant fan, touch theMode button two more times).

In order to run the fan by itself, do the following:

On WY/WS heat-coolmodels, touch theMode button once to activate theFan Only feature. TheFan Only setting will circulate air in the room without the compressor coming on.

3Continuing from MoneySaver® mode, touch theMode button once to activate theFan Only feature (WScool-onlymodels.

To adjust temperature

4Use the Mode button to select either theCool orMoneySaver® function (or Heat for WY/WEheat-coolmodels)

5COOLER – Touch thebutton to lower the room air temperature.

6WARMER – Touch thebutton to raise the room air temperature.

7Press both the andbuttons at the same time to switch the temperature from Fahrenheit (°F) to Celsius (°C). Repeat Step 7 to switch from °C back to °F.

To adjust fan speed

8Touch the Fan Speed button to see the current setting. Touch it again to change speed. F1 is the lowest setting (SLEEP SETTING / LOW), F2 is MEDIUM, and F3 is HIGH.

To activate Smart Fan (WS cool-onlymodels)

9There is a fourth option, SF, when selecting the fan speed. This is the SMART FAN function. SMART FAN DOES NOT OPERATE IN CONJUNCTION WITH THE FAN ONLY MODE.

To activate Smart Fan (WY/WE heat-coolmodels)

9Press the Smart Fan button to activate the Smart Fan. The light will indicate that this feature is in use.

Smart Fan will adjust the fan speed automatically to maintain the desired comfort level. For example, if the outside doors in your home are opened for an extended period of time, or more people enter a room, Smart Fan may adjust to a higher fan speed to compensate for the increased heat load. This keeps you from having to adjust the fan speed on your own.

To set the hour clock

10Touch the Set Hour button to see the current setting. The number that is displayed is the approximate time (hour only).

Use theandbuttons to change the settings. BE SURE TO SET A.M. AND P.M. ACCORDINGLY. (P.M. is indicated by a red light in the upper left corner of the display).

To set the timer

NOTE: Set the HOUR CLOCK (Set Hour) before attempting to set timer functions.

You can set the Start Time andStop Time a minimum of one hour apart, and a maximum of 23 hours apart.

11After setting the time, press the Set Hour button once (Start

light on). Use the andbuttons to select the time that the unit willSTART.

12After selecting the Start Time, press theSet Hour button once.

(Stop Light on). Use the andbuttons to select the time that the unit willSTOP. After selecting the stopping time, press theSet Hour button once.

13Press the Timer On/Off button (light turns on) to activate the timer function. To deactivate this function, press theTimer On/Off button once again (light turns off). Once the on and off times have been selected, they will remain in memory and cycle daily until changed.

NOTE: If the unit is unplugged or the power is interrupted, the HOUR must be reset or theTimer On/Off will not function when desired.

To Activate Money Saver (WY/WE models)

14Press the Money Saver button to activate the Money Saver feature. The light will indicate the Money Saver is in use.

MoneySaver® is a feature that cycles the fan with the compressor so that the fan does not run all the time. This saves energy and improves dehumidification. MoneySaver® will also run to test the temperature if the off cycle is too long. Or you may prefer constant fan for more air movement. (To return to constant fan, touch theMode button two more times).

How to clean the air filter

Your Friedrich room air conditioner is equipped with a Permafoam reusable air filter which is not affected by washing. The filter serves to remove dust, pollen, and other impurities from the air.

KEEP THE FILTER CLEAN - A clogged, dirty filter will reduce the operating efficiency of your unit and contribute to frosting of the indoor coil. Be sure to check the filter every 7 to 10 days. The filter check procedure is easy, due to the unique design of the Friedrich DECORATIVE FRONT.

FILTER ACCESS - Remove the INTAKE GRILLE from the DECORATIVE FRONT frame by grasping it at the upper right and left side corners. Pull out until the GRILLE is released from the upper retaining snaps. Tilt down toward you, lift up and out of the bottom retaining snaps. This will expose the filter. Remove the filter by pulling it toward you. Wash the filter in hot, soapy water, rinse, squeeze lightly to remove excess water, shake dry - do not twist - and replace in the unit on the two support hangers. Replace the INTAKE GRILLE by positioning the bottom of the GRILLE into the bottom retaining snaps. Tilt the front up and away from you. Press in lightly on top and the GRILLE will position itself into the upper retaining snaps.

How to change airflow direction

The DISCHARGE GRILLE is installed at the factory to provide 45˚ upward airflow into the room. (Direction 1 in Figure 5). If a vertical airflow is desired (Direction 2), the direction can be changed by rotating the DISCHARGE GRILLE.

Unplug the air conditioner.

Remove the DISCHARGE GRILLE RETAINER attached with one screw in the right side of the grille.

Remove the DISCHARGE GRILLE from the retaining slots near the CONTROLS, and rotate the grille as shown in Figure 5.

Reinstall the DISCHARGE GRILLE by placing it in its retaining slots. Reattach the DISCHARGE GRILLE RETAINER with the retaining screw. The unit is now ready to operate.

How to cover inner weather panel holes

Two beige plugs are included in the plastic bag taped to the WallMaster chassis. These plugs may be used to cover the two holes left after removing the inner weather panel (see Figure 5). The plugs must be attached before the DECORATIVE FRONT frame is installed.

Electrical requirements

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 supply with the same AC voltage and hertz rating as marked on the nameplate located on the chassis. Only alternating current (AC) can be used. Consult pages 3 and 7 for the correct type of receptacle for your model.

An overloaded circuit will invariably cause malfunction or failure of an air conditioner, therefore, it is extremely important that the electrical power and the wiring is adequate. Consult your dealer or power company if in doubt.

CIRCUIT PROTECTION - Before installing or relocating your Friedrich Room Air Conditioner, check the amp rating of the circuit breaker or"TIME-DELAY"fuse. Refer to the nameplate located on the air conditioner chassis to determine the correct fuse or circuit breaker amperage for your model. The rating MUST NOT exceed the value stated on the nameplate. If the air conditioner is connected to a circuit protected by a fuse, a"TIME-DELAY"fuse must be used due to the momentary high current demands when your air conditioner is started.

Never use an extension cord

Your Friedrich room air conditioner is equipped with a three-prong(grounded) plug for your protection against shock hazards and should be plugged directly into a properly groundedthree-prongreceptacle. If you have atwo-prongreceptacle you will need to have the circuit replaced by a certified 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 thethree-prongplug furnished with the air conditioner.

NEVER CUT OR REMOVE THE GROUNDING PRONG FROM THE PLUG.

Power cord information

All Friedrich room air conditioners are shipped from the factory with a Leakage Current Detection Interrupter (LCDI) equipped power cord. The LCDI device meets the UL and NEC requirements for cord connected air conditioners effective August 2004.

To test your power supply cord:

1.Plug power supply cord into a grounded 3 prong outlet.

2.Press RESET (See Figure 6).

3.Press TEST (listen for click; Reset button trips and pops out).

4.Press and release RESET (listen for click; Reset button latches and remains in). The power supply cord is ready for operation.

NOTE: LCDI device is not intended to be used as a switch.

Once plugged in the unit will operate normally without the need to reset the LCDI device.

If the device fails to trip when tested or if the power supply cord is damaged it must be replaced with a new supply cord from the manufacturer. We recommend you contact our Technical Assistance Line at (800) 541-6645ext. 662. To expedite service, please have your model and serial number available.

NOTE: Your LCDI device will resemble one of these illustrations.

Troubleshooting tips and home maintenance

Won’t cool

If the unit operates, but won’t cool, determine if the controls are properly set. Wait three minutes before setting the thermostat to a cooler position in order to check control settings. Check the filter and clean it thoroughly, if needed. Check to see if the vent door is closed. Check to see if the chassis seal gasket is properly installed (refer to page 14 for seal gasket installation).

Won’t heat (for heat/cool models only)

If the unit operates, but won’t heat, determine if the control settings are correct. Adjust the thermostat to a warmer position to determine if it operates. Also, check the filter and clean it thoroughly, if needed.

Odors in heating (for heat/cool models only)

You may notice a smoke odor the first time the heater element comes on. This is common in any type of heat system when first turned on for the winter. The odor comes from dust and other particles that accumulate during the warm months. The odor will dissipate quickly.

Frosting of the indoor coil

Certain operating conditions may produce indoor coil frost. During the cooling operation, a dirty filter or restricted air distribution in combination with cool, damp weather could cause such an occurrence. Should the indoor coil frost over while cooling, set the control to FAN and keep it running until the frost on the coil is gone. Setting the thermostat to a slightly warmer position will probably keep the coil from frosting over again.

Cleaning the decorative front

The decorative front of your Friedrich room air conditioner, as well as the complete cabinet, may be cleaned with warm water and mild detergent. Under adverse operating conditions, the indoor and outdoor coils and base pan may require periodic cleaning to maintain efficient operation. Your Friedrich dealer should be called when this service is required.

Won’t run

If the unit fails to operate, check to see if the power cord is firmly plugged in. Check for blown fuses, tripped circuit breakers or a tripped LCDI Device (Refer to LCDI reset instructions in the Power cord information section). Restore the circuit breaker or replace the blown fuse with a proper size"TIME-DELAY"fuse. The proper fuse size is shown on pages 4 and 7 in these instructions. After restoring the current supply to the unit, wait three minutes before restarting.

Things to know about a WallMaster heat pump

During the heat pump operation, you may notice some functions that did not occur when the unit was used for cooling:

1.It is common for ice to form on the outdoor coil of your WallMaster Heat Pump. The ice forms due to moisture in the outdoor air passing over cold (below freezing) coil surfaces.

2.When the outdoor coil forms ice, your heat pump will automatically initiate a defrost. The compressor will stop and the fan will continue to run. The electric heat will be turned on to continue warming the room while the outdoor air defrosts the outdoor coil. After the defrost is completed, the unit will automatically return to the heat pump mode.

3.It is normal for vapor (steam) to rise from the outdoor coil during the defrost. This is similar to expelling warm breath on a cold morning.

4.If the outdoor temperature drops below 43°F during heat pump operation, your WallMaster Heat Pump will automatically switch to electric resistance heat and will continue to operate in this mode as long as the outdoor temperature remains at 43°F or below.
