Oz Air Online can help guide you if a warranty issue arises. Firstly you will need to contact the manufacturer as soon as possible and lodge a warranty request. The number for each manufacturer will be on the warranty form which came with the system purchased. You can also find the manufactures contact details here. When placing a warranty claim you will need to provide proof of purchase (your tax invoice).
Reach out to us if you need any assistance or require another copy of your invoice.
