PRODUCT OR ITS COMPONENTS (“COMPONENTS”) BY THERMA-
STOR OR THERMA-STOR’S AGENTS ONLY. REFRIGERANT, PIPING, 
SUPPLIES, TRANSPORTATION COSTS, LABOR COSTS INCURRED

INCLUDED. THIS DISCLAIMER AND EXCLUSION SHALL APPLY 
EVEN IF THE EXPRESS WARRANTY AND LIMITED REMEDY SET 
FORTH HEREIN FAILS OF ITS ESSENTIAL PURPOSE. CUSTOMER 
ACKNOWLEDGES THAT NO REPRESENTATIVE OF THERMA-STOR OR 
OF ITS AFFILIATES OR RESELLERS IS AUTHORIZED TO MAKE ANY 
REPRESENTATION OR WARRANTY ON BEHALF OF THERMA-STOR 
OR ANY OF ITS AFFILIATES OR RESELLERS THAT IS NOT IN THIS

EXCEPT FOR ABOVE LIMITED 

WARRANTY, WHICH IS THE SOLE AND EXCLUSIVE WARRANTY 
PROVIDED WITH RESPECT TO THE PRODUCT AND ITS COMPONENTS, 
THERMA-STOR HEREBY DISCLAIMS ALL EXPRESS AND IMPLIED 
WARRANTIES, INCLUDING, WITHOUT LIMITATION, THE IMPLIED 
WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A 
PARTICULAR PURPOSE. 

Warranty Limitations.

 The foregoing limited warranty extends only 

to a Customer and shall be null and void upon attempted assignment 
or transfer. A “defect” under the terms of the limited warranty shall 
not include problems resulting from Customer’s or Customer’s 
employees’, agents’, invitees’ or a third party’s misuse, improper 
installation, improper design of any system in which the Product 
is included, abuse, lack of normal care, failure to follow written 
instructions, tampering, improper repair, or freezing, corrosion, acts 
of nature or other causes not arising out of defects in Therma-Stor’s 
workmanship or material. If a Product or Component is replaced 
while under warranty, the applicable limited warranty period shall 
not be extended beyond the original warranty time period. The 
limited warranty does not cover any costs related to changes to a 
Product or Component that may be required by any codes, laws, or 
regulations that may become effective after initial purchase of the 
Product by Customer. 

Customer Responsibilities. 

As a further condition to obtaining 

warranty coverage hereunder, the Customer must send a valid 
warranty claim to Therma-Stor such that Therma-Stor receives 
such claim prior to the end of the applicable warranty period. 
Therma-Stor shall have no obligation hereunder with respect to 
any claim received by Therma-Stor after the expiration of the 
applicable warranty period. As a further condition to obtaining 
warranty coverage hereunder, the Customer must present forms of 
invoices evidencing proof of purchase of a Product. If such invoices 
do not clearly indicate the date of initial purchase by a Customer, 
the applicable Product’s date of manufacture will be used instead 
of the date of initial purchase for the purpose of calculating the 
commencement of the applicable warranty period. Warranty service 
must be performed by Therma-Stor or a servicer authorized by 
Therma-Stor. In order to obtain warranty service, the Customer 
should call Therma-Stor at 1-800-533-7533 and ask for the 
Therma-Stor Products Service Department, which will then arrange 
for applicable warranty service. Warranty service will be performed 
during customary, daytime working hours. If the Product must be 
shipped for service, Customer shall be solely responsible for properly 
packaging the Product, for all freight charges, and for all risk of loss 
associated with shipment. 

Limitation of Liability. 

IN NO EVENT SHALL THERMA-STOR, 

IN CONNECTION WITH THE DESIGN, SALE, INSTALLATION, USE, 
REPAIR, REPLACEMENT OR PERFORMANCE OF ANY PRODUCT, 
COMPONENT, PART THEREOF OR WRITTEN MATERIAL PROVIDED 
THEREWITH, BE LIABLE, TO THE EXTENT ALLOWED UNDER 
APPLICABLE LAW, UNDER ANY LEGAL THEORY FOR ANY SPECIAL, 
DIRECT, INDIRECT, COLLATERAL OR CONSEQUENTIAL DAMAGES 
OF ANY KIND. NOTWITHSTANDING THE ABOVE LIMITATIONS AND 
WARRANTIES, THE SOLE AND EXCLUSIVE LIABILITY OF THERMA-
STOR, REGARDLESS OF THE NATURE OR THEORY OF THE CLAIM, 
SHALL UNDER NO CIRCUMSTANCES EXCEED THE PURCHASE PRICE 
OF THE PRODUCT, COMPONENT OR PART UPON WHICH THE CLAIM 
IS PREMISED. 

Applicable Law and Venue.

 ANY ARBITRATION, ENFORCEMENT 

OF AN ARBITRATION OR LITIGATION RELATED TO THE PRODUCT 
WILL BE BROUGHT EXCLUSIVELY IN DANE COUNTY, WISCONSIN, 
AND CUSTOMER CONSENTS TO THE JURISDICTION OF THE 
FEDERAL AND STATE COURTS LOCATED THEREIN, SUBMITS TO 
THE JURISDICTION THEREOF AND WAIVES THE RIGHT TO CHANGE 
VENUE. CUSTOMER FURTHER CONSENTS TO THE EXERCISE OF 
PERSONAL JURISDICTION BY ANY SUCH COURT WITH RESPECT TO 
ANY SUCH PROCEEDING. 

Miscellaneous.

 If any term or condition of this Limited Warranty 

is found by a court of competent jurisdiction to be invalid, illegal or 
otherwise unenforceable, the same shall not affect the other terms 
or conditions hereof or thereof or the whole of this Limited Warranty. 
Any delay or failure by Therma-Stor to exercise any right or remedy 
will not constitute a waiver of Therma-Stor to thereafter enforce 
such rights.
