Tools Needed

How to Install the Unit

1. To prevent vibration and noise, make sure the unit is installed securely and firmly.

2. Install the unit out of direct sunlight.

3. There should be no obstacles, such as a fence or wall, within 20” from the back of the cabinet because it will prevent heat radiation of the condenser. Restriction of outside air will greatly reduce the cooling efficiency of the air conditioner.
   CAUTION
   DO NOT cover or block any of the side and top louvers. All side louvers of the cabinet must remain exposed to the outside of the structure and unobstructed.

4. Install the unit slightly tilted so the back is slightly lower than the front (about 1/2”). This will force condensed water to flow to the outside.

5. Install the unit with the bottom between 30”~ 60” above the floor level.

Window Requirements

• This unit is designed for installation in standard double-hung windows with actual opening widths from 27” to 39”.
• The top and bottom window sashes must open sufficiently to allow a clear vertical opening of 16” from the bottom of the upper sash to the inside sill.

NOTE

• All supporting parts should be secured to firm wood, masonry, vinyl, fiberglass, or metal.
• This product is a window air conditioner. As such, a standard single-hung or double-hung window is required for proper installation. Nonwindow installations, including using sleeves or wall openings, and other installation methods are not recommended.

Storm Window Requirements

• Windows that include a storm window frame may prevent the air conditioner from tilting down toward the outside to drain properly. For proper drainage, attach a 2” x 2” piece of wood to the inner sill, trimmed to a length that fits inside the window frame. The top of the wood shim must be at least 1 1/4” higher than the top of the storm window frame. Attach the wood securely to the sill with nails or screws.
• If necessary, attach another 2” x 2” wood strip flush against the back of the inner sill.

Preparation of the Cabinet

1. Remove 4 screws which fasten the cabinet at both sides and the back. (Keep the screws for later use.)

2. Slide the unit from the cabinet by gripping the base pan handle and pulling forward while bracing the cabinet.
   CAUTION
   The unit is heavy. To prevent injury, use proper lifting techniques when pulling the unit forward from the cabinet. Obtain assistance from another person if possible.

Cabinet Installation

1. Open the window. Mark a line on the center of the inside sill. Carefully place the cabinet in the window and align the center hole on the cabinet bottom front with the center line on the sill.

2. Pull the bottom window sash down behind the upper guide until It meets the cabinet.

   • NOTE
     Do not pull the window sash down so tightly that the movement of the curtain panels is restricted.

3. Loosely assemble each sill support.
   NOTE
   If the distance to the outer window sill is not that deep, you may not need the bolt and nut.

4. Use 2 type A screws to attach a sill support to the cabinet track holes on one side. Use the cabinet track holes that will place the sill support nearest to the outer edge of the sill. The longer side of the sill support should be facing outside the window. Repeat with the second sill support on the opposite side of the cabinet.

5. Install the cabinet with a slight tilt (about 1/2”) downward on the outside. Use the bolt and nut to adjust the tilt of the cabinet.

   • CAUTION
     Do not drill a hole in the bottom pan. The product is designed to operate with approximately 1/2” of water in the bottom pan. There is no need to add water if the pan is dry.

6. Mount the cabinet to the window sill using 3 type B screws in the holes on the front angle.

7. Pull each curtain panel out until it meets the window sash track.

8. Use a screwdriver or power drill to attach the curtain panels to the window sashes by inserting type C screws into the sashes through the cabinet holes shown in the figure below.

Unit Installation

1. With the aid of an assistant, slide the unit into the cabinet. Do not push on the controls or the finned coils. Reinstall the screws removed from the cabinet sides in step 1 of the preparation of the cabinet.
   CAUTION

   • The unit is heavy. Use an assistant to help lift the unit and set it in place. Lifting and maneuvering the unit by yourself could result in injury.
   • Hold the unit firmly in place until the window frame is lowered to meet the top surface of the unit directly behind the upper guide. If the unit falls from the window, it could cause personal injury or property damage.

2. Cut the non-adhesive foam strip to the proper length and insert it between the upper window sash and the lower window sash.

3. To prevent broken glass or damage to windows, on vinyl or other similarly constructed windows, attach the window locking bracket with a type C screw.

• For reasons not attributable to LGE’s negligence, the service may not operate due to external factors such as, but not limited to, Wi-Fi unavailability, Wi-Fi disconnection, local app store policy, or app unavailability.
• The feature may be subject to change without prior notice and may have a different form depending on where you are located.

Using LG ThinQ to Diagnose Issues
If you experience a problem with your Wi-Fi-equipped appliance, it can transmit troubleshooting data to a smartphone using the LG ThinQ application.

• Launch the LG ThinQ application and select the Smart DiagnosisTM feature in the menu. Follow the instructions provided in the LG ThinQ application.

Demand Response Function
When the appliance operates in Demand Response (DR) mode, the Demand Response function can control energy usage or delay the operation of some functions to save energy during peak usage periods.

• You can override the Demand Response function at any time (using the LG ThinQ or the appliance’s control panel).
• To use the Demand Response function, you need to register your appliance with your electric utility company.

MAINTENANCE

WARNING
Before cleaning or performing maintenance, disconnect the power supply and wait until the fan stops.

Cleaning
Check the air filter at least twice a month to see if cleaning is necessary. Trapped particles in the filter can build up and block the airflow, reducing cooling capacity and causing an accumulation of frost on the evaporator.

Cleaning the Air Filter

1. Remove the air filter from the front grille by pulling the filter forward and then up slightly.
2. Wash the filter using lukewarm water below 40 °C (104 °F).
3. Gently shake the excess water from the filter and replace it.

NOTE
The feature may be changed according to the type of model.

Cleaning the Air Conditioner

• Remove dust from the air inlet and outlet using a vacuum cleaner.
• Wipe the front grille and inlet grille with a cloth dampened in a mild detergent solution.
• Wash the cabinet with mild soap or detergent and lukewarm water, then polish using liquid appliance wax.

NOTE

• To ensure continued peak efficiency, the condenser coils (outside of the unit) should be checked periodically and cleaned if clogged with soot or dirt from outside air.
• For repair and maintenance, contact an Authorized Service Center. See the warranty page for details or call 1-800-243-0000. Have your model number and serial number available. They can be found on the side of the cabinet. Record them for future reference.
• The feature may be changed according to the type of model.

PROCEDURE FOR RESOLVING DISPUTES:
ALL DISPUTES BETWEEN YOU AND LG ARISING OUT OF OR RELATING IN ANY WAY TO THIS LIMITED WARRANTY OR THE PRODUCT SHALL BE RESOLVED EXCLUSIVELY THROUGH BINDING ARBITRATION, AND NOT IN A COURT OF GENERAL JURISDICTION. BINDING ARBITRATION MEANS THAT YOU AND LG ARE EACH WAIVING THE RIGHT TO A JURY TRIAL AND TO BRING OR PARTICIPATE IN A CLASS ACTION.

• Definitions. For this section, references to “LG” mean LG Electronics U.S.A., Inc., its parents, subsidiaries, and affiliates, and each of their officers, directors, employees, agents, beneficiaries, predecessors in interest, successors, assigns, and suppliers; references to “dispute” or “claim” shall include any dispute, claim or controversy of any kind whatsoever (whether based in contract, tort, statute, regulation, ordinance, fraud, misrepresentation or any other legal or equitable theory) arising out of or relating in any way to the sale, condition or performance of the product or this Limited Warranty.
• Notice of Dispute. In the event you intend to commence an arbitration proceeding, you must first notify LG in writing at least 30 days in advance of initiating the arbitration by sending a letter to LG at LG Electronics, USA, Inc. Attn: Legal Department- Arbitration 111 Sylvan Avenue, Englewood Cliffs, NJ 07632. You and LG agree to engage in good faith discussions in an attempt to amicably resolve your claim. The notice must provide your name, address, and telephone number; identify the product that is the subject of the claim; and describe the nature of the claim and the relief being sought. If you and LG are unable to resolve the dispute within 30 days, either party may proceed to file an arbitration claim.
• Agreement to Binding Arbitration and Class Action Waiver. Upon failure to resolve the dispute during the 30 days after sending written notice to LG, you and LG agree to resolve any claims between us only by binding arbitration on an individual basis, unless you opt-out as provided below. Any dispute between you and LG shall not be combined or consolidated with a dispute involving any other person’s or entity’s product or claim. More specifically, without limitation of the foregoing, any dispute between you and LG shall not under any circumstances proceed as part of a class or representative action. Instead of arbitration, either party may bring an individual action in small claims court, but that small claims court action may not be brought on a class or representative basis.
• Arbitration Rules and Procedures. To begin arbitration of a claim, either you or LG must make a written demand for arbitration. The arbitration will be administered by the American Arbitration Association (“AAA”) and will be conducted before a single arbitrator under the AAA’s Consumer Arbitration Rules that are in effect at the time the arbitration is initiated (referred to as the “AAA Rules”) and under the procedures outlined in this section. The AAA Rules are available online at www.adr.org/consumer. Send a copy of your written demand for arbitration, as well as a copy of this provision, to the AAA in the manner described in the AAA Rules. You must also send a copy of your written demand to LG at LG Electronics, USA, Inc. Attn: Legal Department- Arbitration 111 Sylvan Avenue, Englewood Cliffs, NJ 07632. If there is a conflict between the AAA Rules and the rules outlined in this section, the rules outlined in this section will govern. This arbitration provision is governed by the
• Federal Arbitration Act. Judgment may be entered on the arbitrator’s award in any court of competent jurisdiction. All issues are for the arbitrator to decide, except that issues relating to the scope and enforceability of the arbitration provision and to the arbitrability of the dispute are for the court to decide. The arbitrator is bound by the terms of this provision.
• Governing Law. The law of the state of your residence shall govern this Limited Warranty and any disputes between us except to the extent that such law is preempted by or inconsistent with applicable federal law.
• Fees/Costs. You do not need to pay any fee to begin an arbitration. Upon receipt of your written demand for arbitration, LG will promptly pay all arbitration filing fees to the AAA unless you seek more than $25,000 in damages, in which case the payment of these fees will be governed by the AAA Rules. Except as otherwise provided for herein, LG will pay all AAA filing, administration, and arbitrator fees for any arbitration initiated by the AAA Rules and this arbitration provision. If you prevail in the arbitration, LG will pay your attorneys’ fees and expenses as long as they are reasonable, by considering factors including, but not limited to, the purchase amount and claim amount. Notwithstanding the foregoing, if applicable law allows for an award of reasonable attorneys’ fees and expenses, an arbitrator can award them to the same extent that a court would. If the arbitrator finds either the substance of your claim or the relief sought in the demand is frivolous or brought for an improper purpose (as measured by the standards outlined in Federal Rule of Civil Procedure 11(b)), then the payment of all arbitration fees will be governed by the AAA Rules. In such a situation, you agree to reimburse LG for all monies previously disbursed by it that are otherwise your obligation to pay under the AAA Rules. Except as otherwise provided for, LG waives any rights it may have to seek attorney’s fees and expenses from you if LG prevails in the arbitration.
• Hearings and Location. If your claim is for $25,000 or less, you may choose to have the arbitration conducted solely based on (1) documents submitted to the arbitrator, (2) through a telephonic hearing, or (3) by an in-person hearing as established by the AAA Rules. If your claim exceeds $25,000, the right to a hearing will be determined by the AAA Rules. Any in-person arbitration hearings will be held at a location within the federal judicial district in which you reside unless we both agree to another location or we agree to a telephonic arbitration.
• Opt-Out. You may opt out of this dispute resolution procedure. If you opt-out, neither you nor LG can require the other to participate in an arbitration proceeding. To opt-out, you must send notice to LG no later than 30 calendar days from the date of the first consumer purchaser’s purchase of the product by either: (i) sending an e-mail to optout@lge.com, with the subject line: “Arbitration Opt Out” or (ii) calling 1-800-980-2973. You must include in the opt-out e-mail or provide by telephone: (a) your name and address; (b) the date on which the product was purchased; (c) the product model name or model number; and (d) the serial number (the serial number can be found (i) on the product, or (ii) online by accessing https://www.lg.com/us/support/repair-service/schedule-repair-continued and clicking on “Find My Model & Serial Number”).

You may only opt out of the dispute resolution procedure in the manner described above (that is, by e-mail or telephone); no other form of notice will be effective to opt out of this dispute resolution procedure. Opting out of this dispute resolution procedure will not affect the coverage of the Limited Warranty in any way, and you will continue to enjoy the full benefits of the Limited Warranty. If you keep this product and do not opt-out, then you accept all terms and conditions of the arbitration provision described above.
