Frequently Asked Questions - WCT12A30B Friedrich

How to clean the air filter?

Remove the front panel by pulling on the handles. Pull out the filter by its handles. Wash it with clean water to remove dust, rinse, squeeze without twisting, and let dry. Replace the filter by inserting each tab into its slot, then reattach the front panel by snapping the push buttons.

What to do if the unit does not start?

Check that the unit is on and the thermostat calls for cool or heat. Make sure the power cord is plugged in and the GFCI RESET button is pressed (a click should be heard). Check the circuit breaker or fuse. If the problem persists, contact a professional.

How to set the temperature?

Use the UP and DOWN arrows on the control panel or remote to increase or decrease the set temperature. In Fahrenheit mode, each press changes the temperature by 1°F; in Celsius mode, by 0.5°C.

How to use the remote control?

Install two AAA batteries in the back compartment. Point the remote at the unit's infrared receiver (no obstacles) within a range of 25 ft (7.60 m). Press ON/OFF to turn the unit on or off. Use the SYSTEM, FAN MODE, FAN SPEED keys and arrows for settings.

How to install the wall sleeve (WSE)?

The wall opening must be 17 1/4 inches high by 27 1/4 inches wide. Place the WSE sleeve with a downward slope of 3/8 inch toward the outside. Secure it to the wall with screws and caulk around the perimeter to prevent leaks. Ensure the drain protrudes at least 9/16 inch outside.

What does the CHECK FILTER indicator mean?

The CHECK FILTER indicator lights up after 1,000 hours of fan operation (about 45 to 60 days). It indicates the filter needs cleaning. To clear the alert, press the CHECK FILTER button. Check the filter every 30 days for optimal performance.

How to lock the control panel?

Access the LOCK menu via the MENU button. Enable locking with the arrows, then set a four-digit access code. Once activated, the ON symbol appears on the screen. To unlock, enter the same code via the LOCK menu.

The unit is not cooling enough, what to do?

Check that the filter is not clogged, the air grille is unobstructed (curtains, furniture), and windows and doors are closed. Ensure the mode is COOL and the set temperature is low enough. If the outdoor temperature is below 60°F (16°C), cooling may be inefficient.

Can I use an extension cord?

No, NEVER use an extension cord. The supplied power cord is designed to handle the unit's current. Using an extension cord can cause overheating, fire, or electrocution. Plug directly into a grounded wall outlet.

How to connect the unit to Wi-Fi?

Access the CnCT menu by pressing the MENU button and navigating with the arrows. Select the CnCT submenu and enable Wi-Fi. On your mobile device, go to www.FriedrichConnect.com, create an account, then add the unit following the on-screen instructions.

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 Selection and Adjustment

Airflow direction adjustment

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.

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 outlet.

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 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 5 for electrical receptacle types).

The power cord has a plug with a grounding prong and a matching receptacle is required.

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 Page 5 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 Page 5 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.

Troubleshooting Tips continued

COMPLAINT CAUSE	SOLUTION
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.
