-
Simple Electromechanical Controls: Intuitive mechanical dials allow staff to easily select cooking temperatures (50°C to 270°C) and set timer durations (1–60 minutes or endless continuous mode).

Operating & Cleaning Guidelines
-
Setup & Preheating: Turn the temperature control dial to your desired setpoint (up to 270°C) and set the timer duration or endless mode. Allow the dual contra-rotating fans to bring the chamber to working temperature before loading your trays.
-
Baking & Humidification: Swing open the lateral door and load your 600x400mm trays or GN 1/1 pans onto the chrome side runners. Engage manual water injection during the initial phase of baking to introduce surface moisture for artisan breads or roasts.
-
End-of-Shift Sanitisation: Allow the cavity to cool completely. Unlatch and remove the inner glass pane from the side-opening door to clean between glass layers. Wipe down the smooth Ever Clean enamel walls with a soft, non-abrasive damp cloth and mild food-safe cleaner.
