THIS LANG OVEN PRODUCES HUMIDITY THAT CAN CAUSE
WARNING
THE INTERIOR FLOORING AND ADJACENT EXTERIOR
FLOORING TO BECOME SLIPPERY. USE EXTREME CAUTION
WHEN WALKING ON A WET OR DAMP FLOOR.
The temperature outside the oven should not exceed 104° F (40°
NOTICE
C). This includes the temperature of the air above and around
the oven.
NOTICE
During the first few hours of operation you may notice a small
amount of smoke coming off of the oven, and a faint odor from
the smoke. This is normal for a new oven and will disappear
after the first few hours of use.
WHEN THE LOADING DOOR IS OPENED, HOT AIR AND STEAM

ARE RELEASED FROM THE OVEN INTERIOR. TO AVOID BURNS
OPEN DOOR SLOWLY AND KEEP YOUR FACE AND HANDS
CLEAR OF THE OPENING. ALL INTERIOR SURFACES ARE
VERY HOT. DO NOT TOUCH ANYTHING WITHOUT OVEN MITTS.
Typical Operation
Preheat oven to desired temperature and allow oven to saturate for twenty minutes.
The steam generator absorbs heat and normalizes temperature in the cooking chamber.
Select a cooking program from the main menu of pre-saved programs. When selected, the temperature
setting changes to the correct temperature for the product.
Load a rack full of product into the oven, engaging the rack carrier automatically.
The door of the oven is closed and the rack is lifted off of the floor, allowing it to rotate smoothly.
If a steam time has been set, water flows into the steam generator and cascades through the labyrinth of
heat reserve, converting the water into steam, which condenses on the food product.
When the steam cycle ends (less than 60 seconds,) the circulation blower starts and air is blown past the
heat exchanger and through the rack full of product.
The rotation of the rack insures that the product is cooked evenly throughout the rack. If venting is
desired, such as with breads, the vent cycle is selected when the program is started.
The vent opens for a limited time, allowing dry air to be drawn into the oven, forcing moist air out into the
hood.
The computer control manages all of the timing and temperature functions and sounds an alarm at the end
of the baking cycle.
Open the cooking chamber door and wait until the rack is rotated so that it is aligned with the door.
Release the latch at the top of the rack and remove the rack from the oven.
