	Indoor temp.: 62 ~ 90°F / 17 ~ 32°C

NOTICE

• The relative humidity of room should be less than 80%. If the unit is used in a condition with a relative humidity over 80%, there will be condensed water on the surface of the unit.
  • Performance may be reduced outside of these operating temperatures.

NOTICE

Always wait 3 minutes when turning the unit off and then on again, or when changing from cool to fan and back to cool. This prevents damage from occurring to the compressor.

To begin operating the air conditioner, follow these steps:

1. Set the temperature to the coldest setting.
2. Set the control to HIGH COOL.
3. Adjust the louver for comfortable air flow (see Air Directional Louvers).
4. Once the room feels cool, adjust to the temperature you find most comfortable.
5. Make sure that the air flow inside and outside are not obstructed.

Air Directional Louvers

The louvers will allow you to direct the air flow Left or Right, or Up and Down (optional on some models) throughout the room as needed.

Move the Levers from side to side until the desired LEFT/RIGHT direction is obtained.

You can also move the LEFT lever to adjust air flow UP/DOWN as needed.

CARE AND CLEANING

CAUTION

Clean your air conditioner occasionally to keep it looking new. Be sure to unplug the unit before cleaning to prevent shock or fire hazards.

Air Filter Cleaning

Models RAC-WK15

Line drawing of a computer tower with ventilation grilles and fan base (no text or symbols)

The air fi liter should be checked at least once a month to see if cleaning is necessary. Trapped particles in the fi liter can build up and cause an accumulation of frost on the cooling coils.

• Push the vent handle to the Vent Closed position (where applicable).
• Open the front panel.
• Grasp the filter by the center and pull up and out.
• Wash the fi Iter using liquid dishwashing detergent and warm water. Rinse fi Iter thoroughly.
• Gently shake excess water from the filter. Be sure the filter is thoroughly dry before replacing.
• You may also vacuum the filter clean rather than washing.

NOTICE

Never use hot water over 104^ F ( 40^ C) to clean the air fi Iter. Never attempt to operate the unit without the air fi Iter.

Cabinet Cleaning

• Be sure to unplug the air conditioner to prevent shock or fire hazard. The cabinet and front may be dusted with an oil-free cloth or washed with a cloth dampened in a solution of warm water and mild liquid dishwashing detergent. Rinse thoroughly and wipe dry.
• Never use harsh cleansers, wax or polish on the cabinet front.
• Be sure to wring excess water from the cloth before wiping around the controls. Excess water in or around the controls may cause damage to the air conditioner.
• Plug in air conditioner.

Winter Storage

If you plan to store the air conditioner during the winter, remove it carefully from the window according to the installation instructions. Cover it with plastic or return it to the original carton.

TROUBLESHOOTING TIPS

Before calling for service, review this list. It may save you time and expense. This list includes common occurrences that are not the result of defective workmanship or materials in this appliance.

Problem Solution

Air conditioner does not start.	Wall plug disconnected. Push plug firmly into wall outlet.
	Circuit breaker tripped. Reset circuit breaker.
	Check if the light on the plug is on. If it is off, press the RESET button.
	Power is OFF. Turn power ON.
	Unit turned off and then on quickly. Turn unit off and wait 3 minutes before restarting.
Air from unit does not feel cold enough.	Room temperature below 62°F (17°C). Cooling may not occur until room temperature rises above 62°F (17°C).
	Temperature sensor behind the air fi Iter is touching the cold coil. Try to move it so it does not contact the cold coil.
	Reset to a lower temperature.
	Compressor shut-off by changing modes. Wait approximately 3 minutes and listen for compressor to restart when set in the COOL mode.
	Check for potential obstructions blocking the outdoor intake/exhaust. Clear any obstructions.
Air conditioner cooling, but room is too warm- ice forming on cooling coil behind air filter.	Outdoor temperature below 64°F (18°C). To defrost the coil, set to FAN ONLY mode.
	Air fi Iter may be dirty. Clean fi Iter. Refer to Care and Cleaning section. To defrost, set to FAN ONLY mode.
	Thermostat set too cold for night-time cooling. To defrost the coil, set to FAN ONLY mode. Then, set temperature to a higher setting.
Air conditioner cooling, but room is too warm- NO ice forming on cooling coil behind air filter.	Dirty or restricted air fi Iter. Clean fi Iter. Refer to Care and Cleaning section. To defrost, set to FAN ONLY mode.
	Temperature is set too high, set temperature to a lower setting.
	Air directional louvers positioned improperly. Position louvers for better air distribution.
	Front of unit is blocked by drapes, blinds, furniture, etc. - restricts air distribution. Clear obstruction in front of unit.
	Any open doors, windows, or registers may allow cold air to escape. Close any doors, windows, or registers.
	The room may be too warm. Allow additional time to remove “stored heat” from walls, ceiling, floor and furniture.
Problem Solution
Air conditioner turns on and off rapidly.	Dirty air fi Iter- air restricted. Clean air fi Iter.
	Outside temperature extremely hot. Set FAN speed to a higher setting to bring air past cooling coils more frequently.
	Check for potential obstructions blocking the outdoor intake/exhaust. Clear any obstructions.
Noise when unit is cooling.	Air movement sound. This is normal. If too loud, set to a slower FAN setting.
	Window vibration - poor installation. Refer to installation instructions or check with installer.
Water dripping INSIDE when unit is cooling.	Improper installation. Tilt air conditioner slightly to the outside to allow water drainage.Refer to installation instructions - check with installer.
Water dripping OUTSIDE when unit is cooling.	Unit removing large quantity of moisture from humid room. This is normal during excessively humid days.
Remote sensing deactivating prematurely (some models).	Remote control not located within range. Place remote control within 16,4 feet & 180°, radius of the front of the unit, and pointed in the general direction of the air conditioner unit.
	Remote control signal obstructed. Remove obstruction.
Room too cold. Temperature setting too low. Increase temperature setting.
Noise when unit starts.	A “da-da” sound may occur for thirty seconds when the unit is turned on due to the compressor starting. It is normal.
Unit will not connect to WiFi or App does not work.	For additional support and troubleshooting tips, follow the link in this QR code:
