MAINTENANCE
Cleaning
WARNING
• Before cleaning or performing maintenance,
disconnect the power supply and wait until the fan
stops.
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
104 °F (40 °C).
3
Gently shake the excess water from the filter
and replace.
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 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.

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 the purposes of 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 a claim for arbitration.
Agreement to Binding Arbitration and Class Action Waiver. Upon failure to resolve the dispute during
the 30 day period 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 set forth 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 set forth in this section, the rules set forth 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 in accordance with 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
27
EN
claim or the relief sought in the demand is frivolous or brought for an improper purpose (as measured by
the standards set forth 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 attorneys’ 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 on the basis of (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 [email protected], 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.
