TestEquity LLC (TestEquity) warrants Environmental Chambers (Equipment) manufactured by TestEquity and supplied under 

this contract to be free from defects in materials and workmanship under normal use and proper maintenance. 

 

TestEquity will repair or replace any defective part for a period of THREE YEARS from the date of invoice. TestEquity reserves 

the right to require any defective part be returned, freight prepaid, to TestEquity’s factory or to inspect any defective part at the 

Purchaser’s site. TestEquity shall have sole discretion to determine whether any part is defective and whether any defective part 

will be repaired or replaced. This limited warranty shall extend to any standard chamber accessory and component part which is 

normally sold by TestEquity. Non-standard accessories and component parts specified by the Purchaser shall be warranted only 

to the extent of the original manufacturer's warranty, if any exists. 

 

If the repair or replacement is performed in the FIRST YEAR from the date of invoice, TestEquity will also pay for the labor 

associated with the repair at the Purchaser's site, subject to TestEquity’s prior approval. During the SECOND and THIRD YEAR 

of the warranty period, Purchaser will be responsible for the installation and cost of installation of replacement or repaired parts.

TestEquity reserves the right to satisfy the labor portion of this limited warranty either through its own service personnel or an 

authorized agent. In order to provide expeditious service, TestEquity reserves the right to satisfy its limited warranty obligation 

by sending replacement parts to be installed by the Purchaser if they can be installed easily without special tools or training. 

TestEquity reserves the right to satisfy this limited warranty by requiring the Purchaser to return the Equipment to TestEquity 

when such return is feasible.

their own without prior approval from TestEquity. Replacement parts must be supplied by TestEquity for in-warranty claims. 

Purchaser will not be reimbursed for parts they buy on their own without prior approval from TestEquity. 

 

The following parts are excluded from this limited warranty and are sold as-is or are considered expendable: interior light bulb, 

viewing window, paint and cosmetic surface finishes and treatments, port plugs, and refrigerant.

locations, Purchaser is responsible for all labor costs for repairs or parts installation, and for all shipping costs associated with 

providing replacement parts. 

 

This limited warranty does not cover: (1) Defects or damages arising as the result of shipment by common carriers or private 

transportation, unless TestEquity undertakes shipment and transportation of the Equipment to Purchaser’s site or contractually 

assumes the risk of damage to the Equipment in shipment; (2) Defects or damages arising out of, or as the result, of mishandling, 

modification, or improper start up, installation or maintenance of the Equipment (including start up, installation or maintenance 

not in accordance with TestEquity’s written procedures); (3) Defects or damages resulting from, or arising out of, abuse, misuse, 

neglect, intentional damage, accident, fire, flood, earthquake, or any other act of God.
