10-Year Full Replacement Warranty
How It Works:
The Details:
Nexus 21 products are manufactured to the highest standards of quality and we are proud to provide the industry’s longest, most comprehensive warranty: 10 years of full-replacement
coverage.*
Nexus 21’s dedicated product-support specialists are ready to assist you with any questions. We ask that our specialists be consulted before any repairs or modifications are attempted, as
these may void the product warranty.
Step 1:
If you experience any problem with a Nexus 21 system, call our Product-Support Team at 1-480-306-5462.
Step 2:
We’ll guide you through some of our basic troubleshooting procedures to help identify any issues. The majority of reported issues are resolved with us on the first call without a need for
replacement parts or systems.
Step 3:
In the event that you do need a replacement part or system, we’ll ship it to you right away, along with a prepaid UPS return shipping label and a package for the defective part or system
to be returned to our office. Nexus 21 will cover the shipping cost of the replacement part or system within the continental United States and Canada (excludes Hawaii, Alaska and Puerto
Rico). Shipping costs for replacement parts or systems shipped internationally will be covered up to a value of $50. Any additional shipping costs, including applicable duties and taxes,
are the responsibility of the customer or receiving party.
Nexus 21 warrants all systems to be free from defects in material and workmanship from the date of purchase until the end of the coverage period (shown below). The warranty includes
all parts, motorized components, electronics and metal parts. If a Nexus 21 system or part proves to be defective in material or workmanship during the expressed warranty period, Nexus
21 will replace it free of charge. If the exact original purchase product is not available (due to upgraded designs or discontinuation of a model), the defective product will be replaced with
a similar product of equal or greater value. The replacement will then be covered by the balance of the time remaining on the customer’s original warranty. A Nexus 21 product-support
representative will determine whether a part or an entire system should be replaced.
*Coverage periods for the warranty are as follows:
Residental and Hotel Use
• All Nexus 21 motorized products (except Apex): 10 years
• Apex Motorized Wall Mount: 5 years
Commercial and Educational Use
• All Nexus 21 motorized products (except Apex): 5 years
• Apex Motorized Wall Mount: 3 years
The Nexus 21 full-replacement warranty does NOT cover: any product on which the serial number has been defaced, modified or removed; damage, deterioration or malfunction resulting
from accident, misuse, neglect, power surges, fire, water, lightning or other acts of nature; unauthorized product modification; failure to follow manufacturer’s recommended installation
instructions supplied with the Nexus 21 system; repair or attempted repair by anyone not authorized by Nexus 21; causes external to the product such as electric power fluctuations or
failure; use of supplies or parts not meeting Nexus 21 specifications or any other cause which does not relate to a product defect.
PLEASE NOTE: In order for any warranty claim to be covered fully under the outlined policy we will require the name, company name or contact information for the original purchaser of
the product to qualify the claim. If the information requested cannot be supplied to us or located on file, replacement parts or systems may not be covered under warranty.
