Installation
WARNING
Installer must be suitably qualified and ensure compliance with all codes and
standards including AS/NZS3500.1.
Failure to comply even partially with installation instructions may void the
warranty.
Positioning
Unpack machine, check for damage and complete delivery. Install machine on
sound waterproof self-draining floor and use adjustable feet to level machine.
Allow room for detergent to one side of machine or in adjacent cupboard. 20litre
container requires about 450H x 250W x 350D, but smaller containers are available
from many suppliers.

smaller than rack with guide to prevent rack falling into sink. Align sink with
dishrack path as shown.
