Important Notes
Batteries are consumable and are not covered. Cosmetic finishes and appearance are excluded. Stainless steel resists staining but is not stain-proof - tea staining is a natural process and is not covered where cleaning and maintenance guidelines have not been followed.
Damage from salt spray, coastal air, high humidity and other corrosives is excluded. In Gold Coast and coastal locations, choose a suitable finish and follow the care and maintenance guidance to protect your hardware and preserve your cover.

This manufacturer's warranty is in addition to other rights and remedies you may have under the law. Our goods come with guarantees that cannot be excluded under the Australian Consumer Law. You are entitled to a replacement or refund for a major failure and to compensation for any other reasonably foreseeable loss or damage. You are also entitled to have the goods repaired or replaced if they fail to be of acceptable quality and the failure does not amount to a major failure.
