The combi oven combines a steam and convection oven into
one versatile unit and can serve a variety of cooking functions.
Alto-Shaam’s combi ovens allow chefs to control humidity and
temperature separately, with powerful results. The same oven can be
used to dehydrate vegetables, roast pork, steam rice, smoke brisket
and bake loaves of bread.
The PROtouch™ recipe management system with one-touch

a HACCP data system pairs up with an onboard USB port, so settings
can be downloaded and saved for the future.
When it’s time to clean up, Alto-Shaam’s CombiClean Plus™
automated cleaning system saves labor previously spent scrubbing
the oven cavity. On the oven’s exterior, a PROrinse™ retractable hose
gives you spray-washing power without opening the oven door.
5. Clean the oven glass with glass cleaner or distilled vinegar.
Re-install the side racks and wire shelves – position shelves with
the curved end up and toward the rear of the oven.
When cleaning is complete, the oven must acclimate to room
temperature in the environment where it is placed.
Twenty four (24) hours is recommended.
The oven is now ready for operation.

Auxiliary Functions and Features
Preheat Feature
The oven should be preheated before most cooking
functions. When cooking full loads, use a temperature
50°F (10°C) greater than the cook temperature in order
to recover from heat loss when the door is opened
to add food to the oven. For items that use the Steam
mode, it is necessary to use a preheat temperature
lower than the cook temperature in order to create the
proper amount ofsteam.

The cool-down feature provides the operator with
the ability to lower the temperature of the oven
compartment at an accelerated pace. This function
is useful when it is necessary to immediately change
from a high temperature cooking function to a lower
temperature function or to the steam program.
This function is also useful to help cool the oven
compartment in preparation for cleaning.
