This document is a user manual for Midea EasyCool Window Air Conditioners, specifically models MAW12S1YWT, MAW10S1YWT, MAW08S1YWT, MAW06R1YWT, MAW05R1YWT, and MAW05M1YWT. It provides comprehensive instructions for installation, operation, maintenance, and troubleshooting.
Function Description:
The Midea EasyCool Window Air Conditioner is designed to provide cooling for indoor spaces. It operates on a 60Hz frequency and offers a cooling capacity ranging from 5000 to 12000 BTU/h, depending on the model. The unit can be controlled via a control panel on the unit itself or with a remote controller. Key operating modes include Cool, Fan, Dry (dehumidifier), and Auto. It also features an Energy Saver function, Sleep mode, and a Timer function for scheduled operation. Some models include a Fresh Air Vent control for recirculating indoor air, drawing in fresh air, or exchanging air. Air directional louvers allow users to adjust the airflow direction.

- Safety Features: Automatic 3-minute time delayed start for the cool circuit to prevent compressor overheating and circuit breaker tripping. Grounding is essential for minimizing shock and fire hazards.
Usage Features:
- Control Panel: Features buttons for ON/OFF, Timer, Sleep, Mode (Auto, Cool, Dry, Fan), Up/Down (temperature/timer adjustment), Fan Speed (Auto, Low, Med, High), ECO (Energy Saver), and Check Filter. Some models (Wi-Fi enabled) also have a Connect Indicator Light.
- LED Display: Shows set temperature (°C or °F), Auto-timer settings, and actual room temperature in Fan Only mode. Displays error codes (AS for room temperature sensor, ES for evaporator temperature sensor, HS for electric heating sensor).
- Operating Modes:
- Cool Mode: Provides maximum cooling with adjustable fan speeds.
- Fan Mode: Circulates room air without cooling; fan speed is adjustable.
- Dry Mode: Functions as a dehumidifier; fan speed is automatically controlled to Low.
- Auto Mode: Automatically selects cooling or fan-only operation based on selected temperature and current room temperature; fan speed is automatically controlled.
- Energy Saver (ECO) Function: The fan runs for 3 minutes after the compressor shuts off, then cycles on for 2 minutes at 10-minute intervals until the room temperature rises above the set temperature, at which point cooling resumes. Available in Cool, Dry, and Auto modes.
- Sleep Mode: Gradually increases the set temperature by 2°F/1°C after 30 minutes, and again after another 30 minutes, maintaining this new temperature for 7 hours before returning to the original setting. Available in Cool and Auto modes.
- Timer Function: Allows scheduling of Auto Start and Auto Stop programs, adjustable in 0.5-hour increments up to 10 hours, then 1-hour increments up to 24 hours.
- Fresh Air Vent Control (MAW10 to MAW12): Allows selection between recirculating indoor air (Vent Closed), drawing in fresh air (Vent Open), or exchanging air (Vent and Exhaust Open).
- Air Directional Louvers: Horizontal louvers pivot for up/down airflow, and levers move side-to-side for left/right airflow.
- Remote Control: Provides full functionality of the unit from a distance of up to 16.4 ft (5 meters). Requires a CR2025 lithium battery.
Maintenance Features:
- Air Filter Cleaning: Recommended at least once a month. The filter can be washed with liquid dishwashing detergent and warm water, rinsed, and dried, or vacuumed. The "Check Filter" LED illuminates after 250 hours of operation as a reminder.
- Cabinet Cleaning: The cabinet and front can be dusted with an oil-free cloth or washed with a damp cloth and mild liquid dishwashing detergent. Harsh cleansers, wax, or polish should be avoided.
- Winter Storage: If storing the unit for winter, it should be removed from the window, covered with plastic, or returned to its original carton.
- Troubleshooting Tips: The manual includes a list of common problems and their solutions, such as the unit not starting, insufficient cooling, ice formation on coils, rapid cycling, noise, and water dripping.
- Safety Precautions: Emphasizes unplugging the unit before cleaning, proper grounding, avoiding damage to the power cord, and proper ventilation when using near gas-burning devices. Specific warnings are provided for units using R32 flammable refrigerant, including not piercing or burning refrigerant tubing and ensuring proper ventilation.
- Professional Service: Recommends contacting an authorized service technician for repairs, maintenance, or power cord replacement, and a qualified electrician for electrical installation or if aluminum house wiring presents problems.
