2.1 Electrical Information
Power Requirements:
120/208-240 VAC, 60 Hz, 30 Amp breaker**
Oven is equipped with a 6-foot flexible shielded power cord.
** See Special Information section below regarding
input voltage to the oven
Electrical connections:
Black Wire: Connect to L1
Red Wire: Connect to L2
White Wire: Connect to N (Neutral)
Green Wire: Connect to GND (Ground)
A dedicated circuit consisting of a dedicated breaker, supply line and
junction box must be used on all oven installations.
Connection details are given on the diagram located on the top of the
oven. The electrical supply should be checked against the diagram to
ensure all electrical and safety requirements are met prior to electrical
connection
Special Information:
Ovens can be special ordered or converted to 120/208 VAC 60 Hz supply
voltage. The 208 VAC ovens are equipped with an additional label
indicating the oven has been converted. Special care should be taken to
ensure ovens converted to 208 VAC are not connected to higher
voltages. Always check wall voltage before installation.

3.0 Commissioning and Operation
3.1 Before using for the first time
New ovens may have a slight odor during the first few uses. To eliminate
the odor quickly, operate the oven at a high temperature for 2 hours.
Make sure the room is well ventilated during this process
Before heating the oven remove all accessories from the oven.
Use a soft cloth or sponge to wipe out the interior using a solution of
warm water and non-abrasive detergent. Dry the interior with a soft cloth
Turn the program to “convection”
Set the temperature to 480 °F / 250 °C using the “+” button while the
indicator light between the “+” and “-“ buttons is lit.
Set the timer by pressing the “Cook” button on H350 models, the “Timer”
button on H373 & H387 models.
“0:00” will appear in the display and the “+/-“ indicator will illuminate.
While the light between the “+/-“ is lit enter 2 hours using the “+” button.
The oven will begin to heat as soon as the indicator light between the “+/-“
goes out.

Time/Temperature button
All time and temperature selections are made using the “+” or “-". To
make changes press one button at a time. For rapid advancement hold in
the button.
- Oven temperatures are 10 °F / 5 °C increments
- Core temperatures are in 2 °F / 1 °C increments
When the light between “+” and “-“ buttons is illuminated, time and
temperatures can be entered or changed.
When the light goes out your entry is accepted.

3.3 Using The Oven
3.3.1 Cooking Using Default Temperatures
Turn the program selector knob to the desired program
H350 H373/H387
The default oven temperature will appear in the display. The indicator
between the “+/-“ buttons will illuminate
The oven will start to heat as soon as the indicator between the “+/-“
buttons goes out.
• Adjust the default temperature if needed
• Allow the oven to preheat if necessary. The oven
temperature can be monitored in the display
• Place food in the oven
• Enter the cooking time
At the end of the cooking time:
A tone will sound for 5 seconds and the →symbol flashes
To turn off the tone and the flashing symbol:
• Press the “Cook” button (H350) “Timer” (H373. H387)
• Turn the program selector to “O”

3.4 Rapid Heat
The rapid heat feature activates the heating elements at maximum
power to heat the oven rapidly. With the “Convection”, “Auto Roast”,
or “Surround” programs the “Rapid heat” feature activates
automatically if the selected temperature is:
• At least 280°F / 140°C in “Auto Roast”
• At least 300°F / 150°C in “Surround”
• A flashing “F” or “C” besides the temperature indicates “Rapid
heat” is on
3.4.1 Turning Off “Rapid Heat”
For some dishes it may be desirable to turn off “Rapid heat” (cookies,
small cakes)
• Select the oven program and temperature
• As soon as the actual temperature appears in the display, “Rapid
heat” can be turned off
• Press the “-“ button and hold until the “F” / “C” in the display stops
flashing
• Once the program selector has been turned to “0”, “Rapid heat”
will be available for the next use

Cooling Air Intake Path
1. Refer to Figure 4-1
2. Via the deflector strips (3)
3. Via the air intake under the door (4)
4. Via the air openings at the rear of the unit (5)
5. Function: To cool the appliance and it’s electrical components
Cooling Air Path
1. Refer to Figure 4-1
2. Via the cooling fan (8)
3. Via the air duct (9)
4. Function: Cool air is mixed across the cooling duct with vapors
removed from the oven via the vapor outlet connection
Cooling Air Discharge
1. Refer to Figure 4-1
2. The cool air and vapor mixture is discharged at the air outlet between
the door handle and fascia panel
4.0.1 Cooling Fan Run-On
The cooling will run during the cooling down cycle until a temperature of
approximately 160 °F is reached. This will prevent damage caused by
condensation collecting in the appliance. During this cycle the cooling fan
operates at the lowest speed. The length of the run on time is determined
by the temperature inside the oven cavity and may be more then one
hour. Opening the door can terminate the run-on.

4.1 Catalyser System (H387 Models)
Figure 4-2: Cooling and Venting Air Paths – Novatronic Ovens With Self-Clean (H387)
1. Refer to figure 4-2
2. The catalyser (3) removes grease particles from expelled air to
reduce odors
3. Grease particles and substances producing odors are converted
to water and carbon dioxide.
4. The water and carbon dioxide are removed by the cooling fan (2)
and expelled via the vent duct (1)

4.1.2 Pyrolitic or Self-Cleaning (H387 Models)
The Miele pyrolitic or self-cleaning system is a thermal process for
cleaning the oven (self-cleaning). At a temperature of approximately 900°
F solid residues are converted to a gaseous state. The catalyser
minimizes smoke and odor development.
Heating: During pyrolitic or self- cleaning, the pyrolitic or self-cleaning
heater element (outer element) is constantly activated. The grill (inner
heater element) and convection fan elements are activated alternately.
Door Lock: The oven door is locked immediately after the start of the
function and only releases after the cycle is complete and the
temperature has dropped below approximately 390°F
Pyrolitic or Self-Cleaning Duration: The duration of the pyrolitic or self-
cleaning cycle ranges based upon the cleanliness of the oven. The
cleaner the oven the shorter the time required to clean and vice versa.
Refer to Figures 4-3 and Figure 4-4.
