Quest CDG 174 Dehumidifier Limited Warranty 

Warrantor:

Therma-Stor LLC 

4201 Lien Rd 

Madison, WI 53704 

Telephone: 1-866-933-7486

Who Is Covered: This warranty extends only to the original end-user of the Quest CDG 174 

dehumidifier, and may not be assigned or transferred.
Year One: Therma-Stor LLC warrants that, for one (1) year the Quest CDG 174 dehumidifier will operate free from any defects in 

materials and workmanship, or Therma-Stor LLC will, at its option, repair or replace the defective part(s), free of any charge.
Year(s) Two Through Five: Therma-Stor LLC further warrants that for a period of five (5) years, the condenser, evaporator, and 

compressor of the Quest CDG 174 dehumidifier will operate free of any defects in material or workmanship, or Therma-Stor LLC, 

at its option, will repair or replace the defective part(s), provided that all labor and transportation charges for the part(s) shall be 

borne by the end-user.
End-User Responsibilities: Warranty service must be performed by a Servicer authorized by Therma-Stor LLC. If the end-user 

is unable to locate or obtain warranty service from an authorized Servicer, he should call Therma-Stor LLC at the above number 

and ask for the Therma-Stor Service Department, which will then arrange for covered warranty service. Warranty service will be 

performed during normal working hours.
The end-user must present proof of purchase (lease) upon request, by use of the warranty card or other reasonable and reliable 

means. The end-user is responsible for normal care. This warranty does not cover any defect, malfunction, etc. resulting from 

misuse, abuse, lack of normal care, corrosion, freezing, tampering, modification, unauthorized or improper repair or installation, 

accident, acts of nature or any other cause beyond Therma-Stor LLC’s reasonable control.
Limitation and Exclusions: If any Quest CDG 174 Dehumidifier part is repaired or replaced, the new part shall be warranted for 

only the remainder of the original warranty period applicable thereto (but all warranty periods will be extended by the period of 

time, if any, that the Quest CDG 174 Dehumidifier is out of service while awaiting covered warranty service).
UPON THE EXPIRATION OF THE WRITTEN WARRANTY APPLICABLE TO THE Quest CDG 174 OR ANY PART 

THEREOF, ALL OTHER WARRANTIES IMPLIED BY LAW, INCLUDING MERCHANTABILITY AND FITNESS FOR A 

PARTICULAR PURPOSE, SHALL ALSO EXPIRE. ALL WARRANTIES MADE BY THERMA-STOR LLC ARE SET FORTH 

HEREIN, AND NO CLAIM MAY BE MADE AGAINST THERMA-STOR LLC BASED ON ANY ORAL WARRANTY. IN 

NO EVENT SHALL THERMA-STOR LLC, IN CONNECTION WITH THE SALE, INSTALLATION, USE, REPAIR OR 

REPLACEMENT OF ANY Quest CDG 174 OR PART THEREOF BE LIABLE UNDER ANY LEGAL THEORY FOR ANY 

SPECIAL, INDIRECT OR CONSEQUENTIAL DAMAGES INCLUDING WITHOUT LIMITATION WATER DAMAGE 

(THE END-USER SHOULD TAKE PRECAUTIONS AGAINST SAME), LOST PROFITS, DELAY, OR LOSS OF USE OR 

DAMAGE TO ANY REAL OR PERSONAL PROPERTY.
Some states do not allow limitations on how long an implied warranty lasts, and some do not allow the exclusion or limitation of 

incidental or consequential damages, so one or both of these limitations may not apply to you. 
Legal Rights: This warranty gives you specific legal rights, and you may also have other rights which vary from state to state.
