Clean the Oven Using the STEAM Mode
Before using the steam oven for the first time, heat it once
while it is empty:
1. Fill and slide in the water tank (see instructions under
"Water Tank", page 7).
2. Remove all accessories from the oven (cooking
inserts, wire rack).
3. Close the oven door.
4. Turn the Mode Selector Knob to STEAM. Press
ENTER.
5. Select ENTER again to access the settings menu.
6. Using the "+/–" buttons, select TIMERS.
7. Using the "+/–" buttons, select OVEN TIMER. Press
ENTER.
8. Set the cooking time for 20 minutes (0:20, in HR/MIN
format). Press ENTER.
— The oven will heat for 20 minutes and then stop.
Countdown will begin after the oven has finished
preheating.
This initial cleaning will also calibrate the steam oven to the
air pressure at your location. Calibration produces more
steam than ordinary use.

Automatic Calibration

The boiling point depends on the air pressure. The higher
the altitude, the lower the air pressure, and also the boiling
point. The steam oven automatically calibrates to adjust to
the pressure conditions in your area the first time steam is
used at 212°F (100°C).
Calibrating the Steam Oven
1. Remove all accessories from the oven (cooking
inserts, wire rack). The oven must be empty and cold.
2. Turn the Mode Selector Knob to STEAM. More steam
than usual will be produced during calibration.
Calibration takes about 15 minutes to complete. Do not
interrupt the calibration cycle. Do not open the oven door
during calibration. Should the calibration process be
interrupted by opening the door or switching off the
appliance, the steaming function will not operate properly.
Recalibrate the appliance manually if you should move to
ensure that the steam oven automatically adjusts to your
new location. Refer to "Operation" to reset all parameters to
.

Recalibration is not necessary after a power failure.

Steam Oven Default Settings
With the steam oven OFF, you can access various other
oven features. Many of these features should be adjusted
when the oven is first installed or after a move to a new
location.
Using the "+/–" buttons, choose SETTINGS and press
ENTER on the initial options on the display screen. The full
list of settings will display:

ALARM DURATION
Use the "+/–" buttons to scroll through the settings list,
pressing ENTER for the one you wish to adjust.
LANGUAGE: Instead of manually changing weight or
temperature units, you can go to LANGUAGE and select
either ENGLISH or FRENCH. Choosing ENGLISH defaults
the weight and temperature units to lbs/°F. Choosing
FRENCH defaults these settings to kg/°C. The display will
change to CUSTOM if you change either of the units by
going directly to them in the settings list.
WATER HARDNESS: The hardness of the tap or bottled
water (NEVER distilled water) you put in the water tank
should be determined and entered with this setting when
the appliance is installed. As explained on page 6, you may
either use water hardness strips or contact your local water
utility to find out the hardness of your tap water.
Enter WATER HARDNESS and set it to this value using the
"+/–" buttons for the number scale. If you move or if your
water source changes, you will need to reset the water
hardness value.
CALIBRATE OVEN: This setting resets the temperature
calibration to 210°F (100°C) the next time the STEAM mode
is used. (See also "Automatic Calibration" on page 8).
TEMPERATURE UNITS: If you choose this setting, you
can override the LANGUAGE default and manually select
either degrees Fahrenheit (°F) or Celsius (°C) for the
temperature display. The calculation for conversion
between temperatures in Fahrenheit and Celsius is shown
below (T = temperature):
T°(Fahrenheit) = T°(Celsius) x 9/5 + 32
