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
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 1 000 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
22 Air Conditioner
WARRANTY (USA)
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 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;
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.

WARRANTY (CANADA)
WARRANTY (CANADA)
ARBITRATION NOTICE: THIS LIMITED WARRANTY CONTAINS AN ARBITRATION PROVISION
THAT REQUIRES YOU AND LG TO RESOLVE DISPUTES BY BINDING ARBITRATION INSTEAD OF
IN COURT, UNLESS THE LAWS OF YOUR PROVINCE OR TERRITORY DO NOT PERMIT THAT, OR,
IN OTHER JURISDICTIONS, IF YOU CHOOSE TO OPT OUT. IN ARBITRATION, CLASS ACTIONS
AND JURY TRIALS ARE NOT PERMITTED. PLEASE SEE THE SECTION TITLED “PROCEDURE FOR
RESOLVING DISPUTES” BELOW.
PROCEDURE FOR RESOLVING DISPUTES:
EXCEPT WHERE PROHIBITED AT LAW, 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. EXCEPT WHERE PROHIBITED AT LAW, YOU AND LG BOTH
IRREVOCABLY AGREE TO WAIVE 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 Canada, 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
LGECI Legal Team at 20 Norelco Drive, North York, Ontario, Canada M9L 2X6 (the “Notice of
Dispute”). 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 of LG’s receipt of the Notice of Dispute,
the dispute shall be resolved by binding arbitration in accordance with the procedure set out herein.
You and LG both agree that, during the arbitration proceeding, the terms (including any amount) of
any settlement offer made by either you or LG will not be disclosed to the arbitrator until the
arbitrator determines the dispute.
Agreement to Binding Arbitration and Class Action Waiver. Upon failure to resolve the dispute during
the 30 day period after LG’s receipt of the Notice of Dispute, you and LG agree to resolve any claims
between you and LG only by binding arbitration on an individual basis, unless you opt out as provided
below, or you reside in a jurisdiction that prevents full application of this clause in the circumstances
of the claims at issue (in which case if you are a consumer, this clause will only apply if you expressly
agree to the arbitration). To the extent permitted by applicable law, 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, except to the extent such a prohibition
is not permitted at law, 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 except to the extent this prohibition is not permitted at law in your province or
territory of jurisdiction as it relates to the claims at issue between you and LG.
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 private and confidential, and conducted on a
simplified and expedited basis before a single arbitrator chosen by the parties under the provincial or
24 Air Conditioner
WARRANTY (CANADA)
territorial commercial arbitration law and rules of the province or territory of your residence. You
must also send a copy of your written demand to LG at LG Electronics, Canada, Inc., Attn: Legal
Department- Arbitration, 20 Norelco Drive, North York, Ontario M9L 2X6. This arbitration provision is
governed by your applicable provincial or territorial commercial arbitration legislation. 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 province or territory of your purchase shall govern this Limited
Warranty and any disputes between you and LG except to the extent that such law is preempted by
or inconsistent with applicable federal or provincial/territorial law. Should arbitration not be permitted
for any claim, action, dispute or controversy between you and LG, you and LG attorn to the exclusive
jurisdiction of the courts of the province or territory of your purchase for the resolution of the claim,
action, dispute or controversy between you and LG.
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 unless you seek more than $25
000 in damages, in which case the payment of these fees will be governed by the applicable
arbitration rules. Except as otherwise provided for herein, LG will pay all filing, administration and
arbitrator fees for any arbitration initiated in accordance with the applicable arbitration 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 applicable laws), then the payment of all
arbitration fees will be governed by the applicable arbitration 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 applicable arbitration 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 (1) on the basis of documents submitted to the arbitrator, (2) through a telephonic
hearing, or (3) by an in-person hearing as established by the applicable arbitration rules. If your claim
exceeds $25 000, the right to a hearing will be determined by the applicable arbitration rules. Any in-
person arbitration hearings will be held at the nearest, most mutually-convenient arbitration location
available within the province or territory in which you reside unless you and LG both agree to another
location or agree to a telephonic arbitration.
Severability and Waiver. If any portion of this Limited Warranty (including these arbitration
procedures) is unenforceable, the remaining provisions will continue in full force and effect to the
maximum extent permitted by applicable law. Should LG fail to enforce strict performance of any
provision of this Limited Warranty (including these arbitration procedures), it does not mean that LG
intends to waive or has waived any provision or part of this Limited Warranty.
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
