Congratulations on choosing a Sistem Air central unit! The materials used and the construction quality make it an extremely reliable product, made even more exceptional by a full 6-year T-warranty warranty, which starts from the registration date on the website www.sistemair.it. The T-warranty warranty covers all the construction elements of the central vacuum unit (excluding replacement bags) whose purchase must be proven by a valid tax document that identifies the product. Damage caused by negligence, mishandling, inappropriate use or tampering will not be covered by warranty. Sistem Air will take over the supply of spare parts, replaced under warranty, excluding transport and labor costs. To activate the T-Warranty warranty, simply register on the website by entering the unique serial number present in the T-Warranty envelope, which can be purchased from your trusted wholesaler.
