ACAI recommends that if you are going to install a cooktop have it installed by a certified, fully insuranced experienced professional. There are so many cowboys up here in the Top End its hard to tell. Ask to see their Contractors card & insurance. If something goes wrong you want to know you are covered & not left paying the bill. The experienced installer will always install as per manufacturers instructions. They will also show you how to operate your new equipment before they go & clean up after themselves. Shown below are the main areas that Consideration must be made before you select your cooktop in our experience.
