Call us from the location of the installation. We will run through a number of steps to test the product's performance. If it appears that an exchange is necessary, we will send an e-mail to the wholesaler from whom you purchased the product, saying that we approve the replacement. The email will also contain the RMA (Return Merchandise Authorisation) number of your request. Your wholesaler will only exchange products with a valid RMA number. So make sure to always call us first!
