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 LLC 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

LIMITATIONS AND EXCLUSIONS: If any Quest 876 Dehumidifier Dehumidifier part is repaired or replaced, the new

will be extended by the period of time, if any, that the Quest 876 Dehumidifier Dehumidifier is out of service while 

awaiting covered warranty service).

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 limitation 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.
