All Calpha products purchased from Calpha or their official dealers come with a limited warranty (as shown below). This limited warranty covers substantial defects in workmanship & materials and, for some products, performance.

The warranty period started from the original purchaser’s date of recipient.

Warranty Period

*Please Note: For safety, any wiring work should be performed by a licensed electrician. Failure to properly install or operate the equipment will void the warranty.

**Prorated Warranty Details:

Within a valid warranty, Calpha will choose from the following two options:***

(1) repair the product at no charge, using brand new or refurbished replacement parts;
(2) exchange the product with a functionally equivalent product that is new or which has been manufactured from serviceable used parts.

All replacements will be compatible with the original products with an equal power rating. A replacement product/part assumes the remaining warranty of the original product or ninety (90) days from the date of replacement or repair, whichever provides longer coverage for you.

The transfer of property ownership is completed once a original product and its repaired product or replacement have been exchanged.The replaced product or part becomes Calpha’s property and the replacement product or part becomes your property.

*** Please Note: If a warranty claim is invalid for any reason, the purchaser will be charged for

necessary expenses incurred by Calpha (e.g. shipping, labor and material costs).
