2. Always ensure that scraper tool blades are
changed regularly to ensure that the scraper
tool works efficiently and prevents damage to
the griddle plate surface.
3. Clean the range castings with a stiff nylon brush
or a flexible spatula to remove any food debris.
Daily Cleaning
1. The grease / spill tray(s) should be checked and
emptied frequently to prevent overflow and
spillage. Remove the spill tray(s) while still warm
so that the grease is in a liquid state. Empty any
grease from the trays and wash the trays
thoroughly in the same manner as any cooking
utensil.
2. Clean the control panel with a damp cloth light-
ly moistened with a solution of mild
detergent and water. Wipe dry with a clean dry
cloth.
3. Remove the burner caps, bases, the trivets and
thoroughly clean including the splash back,
interior and exterior surfaces of the range with
hot water, a detergent solution and a soft
scrubbing brush.
4. Brush the griddle surface (optional - if fitted) with
a soft bristled brush. Any carbon deposits should
be removed using a scraper tool followed by
wiping with a cloth to prevent accumulation of
food deposits.
5. Dry the Range thoroughly with a dry cloth and
polish with a soft dry cloth.
Weekly Cleaning
NOTE:
 If the Range usage is very high, we recommend
that the weekly cleaning procedure is carried out
on a more frequent basis.
 Ensure that protective gloves are worn during the
cleaning process.
 DO NOT use harsh abrasive or caustic detergents
or strong solvents as they will damage the
cooktop, burners and griddle plates (if fitted).
 DO NOT use water on the trivets, griddle plates
and burners while they are still hot as cracking
may occur. Allow these items castings to cool
and remove for cleaning.
 DO NOT clean the burners in a dishwasher.
General
General
Clean the Range regularly. A clean Range looks
better, will last longer and will perform better.
Carbonised grease on the surface or between the
trivets, griddle plates will hinder the transfer of heat
from the cooking surface to the food. This will result
in loss of cooking efficiency.
NOTE:
