This document is an owner's manual for an LG refurbished window air conditioner, model R-LW1516ER. It provides comprehensive information on safety, installation, operation, maintenance, and troubleshooting for the appliance.

Function Description:

The LG R-LW1516ER is a window-mounted air conditioner designed to cool and dehumidify a room. It offers multiple operating modes including Energy Saver, Cool, Fan, and Dry, allowing users to select the most appropriate setting for their comfort needs. The unit is equipped with a slinger fan to improve efficiency by picking up and expelling condensed water through the condenser.

Important Technical Specifications:

Type: Window Air Conditioner
Model: R-LW1516ER
Electrical Data: Standard 120 V, 3-wire grounding receptacle rated 15 A / 120 VAC / 60 Hz. Requires a 15 A time delay fuse or 15 A circuit breaker.
Refrigerant: R32 (flammable refrigerant, requiring special safety precautions during handling and service).
Window Requirements: Designed for standard double-hung windows with opening widths from 29" to 41". Requires a clear vertical opening of 19" minimum from the bottom of the upper sash to the inside sill. The height offset between the inside sill and outside sill must be less than 1 1/4".
Temperature Control Range: The thermostat can be set between 60 °F-86 °F (16 °C-30 °C).

Usage Features:

Control Panel and Remote Control: The unit can be operated via a control panel on the unit itself or a wireless remote control.
Power On/Off: A dedicated Power button turns the air conditioner on or off.
Fan Speed: Users can select from Low (F1), Medium (F2), or High (F3) fan speeds.
Delay ON/OFF Timer:
- Delay ON: When the unit is off, it can be set to automatically turn on from 1 to 24 hours later, retaining previous mode and fan settings.
- Delay OFF: When the unit is on, it can be set to automatically turn off from 1 to 24 hours later. Each press of the Timer button advances the timer by 1 hour.
Operation Modes:
- Energy Saver: In this mode, the compressor and fan turn off when the set temperature is achieved. The fan periodically turns on (approximately every 3 minutes) to allow the unit sensor to accurately determine if more cooling is needed. This is the default mode when the unit is switched on, except in Fan mode or after a power outage.
- Cool: Ideal for rapid cooling and dehumidification. Temperature and fan speed (High, Medium, Low) are adjustable.
- Fan: Circulates air without compressor operation. Fan speed (High, Medium, Low) is adjustable, but temperature cannot be set.
- Dry: Designed for dehumidification on rainy and damp days, rather than significant cooling. Humidity is removed through compressor operation with the fan speed fixed at Low. Fan speed is not adjustable in Dry mode.
Clean Filter Indicator: An LED lights up after 250 hours of operation to remind users to clean the air filter. This reset must be done via the control panel.
Auto Restart: In case of a power outage, the air conditioner will automatically restart with its previous settings once power is restored.
Ventilation: A ventilation lever allows users to choose between a closed position for best cooling performance or an open vent to draw fresh air into the room.
Air Direction Control:
- Horizontal Airflow: Adjusted by moving the levers of the vertical louvers left or right.
- Vertical Airflow: Adjusted by touching the horizontal louvers up or down.
Remote Control Battery: Uses one new AAA 1.5 V battery. The remote control sensor should not be exposed to direct sunlight for optimal operation.

Maintenance Features:

Air Filter Cleaning: The air filter should be checked at least twice a month and cleaned if necessary. Trapped particles can reduce cooling capacity and cause frost accumulation. To clean, remove the filter, wash it with lukewarm water (below 40 °C / 104 °F), gently shake off excess water, and replace.
Air Conditioner Cleaning: The front grille and inlet grille can be wiped with a cloth dampened in a mild detergent solution. The cabinet can be washed with mild soap or detergent and lukewarm water, then polished with liquid appliance wax.
Condenser Coil Inspection: Condenser coils (outside of the unit) should be periodically checked and cleaned if clogged with soot or dirt to ensure continued peak efficiency.
Service and Repair: For repair and maintenance, users are advised to contact an Authorized Service Center. The manual provides a customer information center number (1-800-243-0000) and recommends having the model and serial number available.
Safety Precautions: Before cleaning or performing maintenance, the power supply must be disconnected, and the fan must stop. Users are warned not to touch metal parts when removing the air filter or use strong cleaning agents, solvents, or spray water directly on the unit.
