 Warranty 

 

NUVAIR extends a limited warranty, which warrants the Pro He

TM

 to be free from defects in materials 

and workmanship under normal use and service for a limited period.  The Pro He is warranted according 
to the pro-rated terms as set forth below.  This warranty is not transferable. 
 
NUVAIR will, at it’s discretion and according to the terms as set forth within, replace or repair any 
materials which fail under normal use and service and do not exhibit any signs of improper maintenance, 
misuse, accident, alteration, weather damage, tampering, or use for any other than the intended purpose.  
Determination of failure is the responsibility of NUVAIR, which will work together with the customer to 
adequately address warranty issues.  When any materials are repaired or replaced during the warranty 
period, they are warranted only for the remainder of the original warranty period.  This warranty shall be 
void and NUVAIR shall have no responsibility to repair or replace damaged materials resulting directly or 
indirectly from the use of repair or replacement parts not approved by NUVAIR. 
 
Terms: 
NUVAIR warrants the Pro He to be free from defects in material and workmanship for a period of twelve 
(12) months from date of purchase.  The warranty covers parts and labor. 
 
A warranty registration card, supplied with system documentation, must be filled out and submitted to 
NUVAIR for the warranty to be registered.  If the warranty registration card is not received within ten (10) 
days of purchase, the warranty will begin with the date of manufacture by NUVAIR. 
 
Maintenance Items: 
Any materials which are consumed, or otherwise rendered not warrantable due to processes applied to 
them, are considered expendable and are not covered under the terms of this policy.  This includes 
batteries. 
 
Return Policy: 
Application for warranty service can be made by contacting NUVAIR during regular business hours and 
requesting a Return Material Authorization number.  Materials that are found to be defective must be 
shipped, freight pre-paid, to the NUVAIR office in Oxnard, California.  Upon inspection and determination 
of failure, NUVAIR shall exercise its options under the terms of this policy.  Warranty serviced materials 
will be returned to the customer via NUVAIR’s preferred shipping method, at NUVAIR’s expense.  Any 
expedited return shipping arrangements to be made at customer’s expense must be specified in 
advance. 
 
Limitation of Warranty and Liability: 
Repair, replacement or refund in the manner and within the time provided shall constitute NUVAIR’S sole 
liability and the Purchaser’s exclusive remedy resulting from any nonconformity or defect. NUVAIR shall 
not in any event be liable for any damages, whether based on contract, warranty, negligence, strict 
liability or otherwise, including without limitation any consequential, incidental or special damages, arising 
with respect to the equipment or its failure to operate, even if NUVAIR has been advised of the possibility 
thereof.  NUVAIR makes no other warranty or representation of any kind, except that of title, and all other 
warranties, express or implied, including warranties of merchantability and fitness for a particular purpose, 
are hereby expressly disclaimed. No salesman or other representative of NUVAIR has authority to make 
any warranties.
