The oven should be cleaned inside and outside on a daily
basis. Outside cleaning: Never use steel wool or abrasive
cleaning material to clean the exterior. Use a moist towel
or recommended stainless steel cleaner.
• Switch off the oven and keep the door closed. The oven
fans will cool down the oven automatically.
• Before starting to clean the oven wait at least 30
minutes to cool down.
• Be careful and make sure it is not hot before reaching
into the oven. Wait until it is cool.
• Please remove the stone and the stone holder made of
chrome nickel steel.
• For safety pull the plug before cleaning the oven.
• Do not use a water jet to clean the appliance. Sever
damage or electrical hazard could result. The warranty
becomes void if appliance is flooded.
• Use a damp clean cloth or sponge to clean the
appliance. If the oven is heavily soiled a liquid
detergent can also be used. After the application of
liquid detergent the baking chamber must be wiped
down with clean water.
• We recommend using a liquid detergent, which is
certified for food industrial use and has capabilities of
removing lipids, proteins and organic substances.
DAILY CLEANING
Wait for the oven to cool down completely. Wear safety
gloves. Remove the stone holder and stone. You may want
to clean the oven in the morning when the oven is cool -
before food production begins.

CLEANING

Spray oven cleaner on the side and back walls of the
baking chamber and on the bottom of the baking chamber.
Soak the wire cooking shelf with cleaning detergent to
remove food residue. Wear safety gloves.
Wipe with a damp cloth. Afterwards rinse with fresh
water. You may also use a scotch brite sponge or a plastic
scouring pad to clean the wire cooking shelf.
Before cleaning the stone, be sure the stone has cooled
completely to prevent cracking. To clean the stone use
a damp towel or sponge and fresh water. Do not use a
strong detergent. This can affect the taste of the food.
Discolored marks on the stone are not a sanitation threat,
but be sure to remove larger particles from the surface.
As the water soaks in, wipe off food residue from the door
plate and rinse surface by wiping with a sponge and clean
warm water.

WEEKLY CLEANING
Regularly clean the back vents of the oven of dust and
grease. Be sure the oven has cooled down and the fans are
not running. Use a damp towel. If the cooling vents are
blocked, the oven could malfunction.
Regularly check that the wall clearances are sufficient
otherwise damage to the appliance and surroundings may
occur. Do not store anything directly on the oven.
Keep at least 15 cm distances from heat sources, like a
grill or other heating appliances. Keep at least 102mm
space on the left and right sides, and 300mm clearance
from the back. An optional Alto-Shaam heat shield can be
used in the back to reduce the rear clearance requirement
to 0mm.
Failing to do so will void warranty and cause premature
failure of components. Please refer to the instruction
manual.
Clean the front of the oven the same way. Be sure the
contact area between door and oven front is always clean
and free of debris. Build up of particles in this area can
cause the oven to malfunction.
Wipe the inside of the baking chamber as the detergent
has soaked in. Rinse surfaces by wiping with a sponge and
clean warm water.

STEP 1: PREPARE FILE
Copy the firmware file named “AS420UI1.bin” to a good
quality USB drive. The file name must always be the same.
This means you have to make sure not to mix up different
firmware files on your computer. After the update is finished,
always check the version number on the start screen to be
sure the right version is installed.
STEP 2: PREPARE OVEN
Connect the USB drive to the USB port of the oven and
open the door. Disconnect the main power for 10 seconds.
Alternatively turn off the main circuit breaker for 10 seconds.
STEP 3: PERFORM UPDATE
Reconnect the main power and wait for 20 seconds. The
Update process starts instantly. The LED on the USB Drive
flashes fast, then stops, then flashes fast again, then stops
and flashes slowly (update finished).
During these 20 seconds:
•DONOTinterruptpower!
•DONOTremovetheUSBdrive!DONOTtouchany
buttons/switches!
STEP 4: RESET
After 20 seconds, when the LED on the USB drive flashes
slowly, remove the USB drive and close the door. Then
disconnect the main power again for 10 seconds.
STEP 5: POWER ON AND VERIFY
Connect the main power again. Then power on the control
panel. On the bottom of the start screen the current firmware
version is displayed.

CHANGE DOOR SWITCH
First check that the door is closing properly. If debris
builds up on the door it might not close properly and the
door switches are not activated properly.
STEP 1
Unplug, or disconnect the main power of the oven (not
onlythefuse!),thenopentheservicepanelontheright
side of the oven. Remove the top of the oven. The door
switch is located on the upper left corner of the electric
board. Open the door.
STEP 2
Disconnect the cables of the PCB. Disconnect the cables of the door switch.

CHANGE DOOR SWITCH
STEP 5
Reinstall the electric board with the six screws. Then
reconnect the cables to the PCB (keypad cable black side
up).
STEP 3
Unscrew the six mounting screws of the electric board (two at the bottom, two at the upper left, two at the upper right).
Then carefully move the electric board towards you to gain access behind the electric board.
STEP 4
Now unscrew the four screws of the door switch assembly,
remove it and assemble the new door switch assembly.
Reassemble the four screws. But do not fully tighten the
screws at this point, so the new door switch can move
freely for later adjustment.

CHANGE DOOR SWITCH
STEP 6
Connect the cables back to the new door switch assembly. The cables are marked S11, S12, etc. The first two letters
indicate which switch to connect the cable to (S3 at the top, S1 at the bottom left, S2 at the bottom right). The third
number indicates which contact of each switch. (1 upper contact COM, 2 middle contact NO, 3 lower contact NC). For
example S11 has to be connected to the upper COM contact (1) of the Switch S1 at the bottom right.
STEP 7: ADJUSTING THE DOOR SWITCH
With everything back in place, the four screws of the
door switch have to be loose, otherwise the door switch
assembly might be damaged when closing the door. Slowly
close the door.
STEP 8
Push the upper switch towards the left until the trigger
of the switch just touches the outside of the switch. Do
not press so hard that the trigger bends over the housing
of the switch. When you have the right position, fix the
position with the screw. Repeat with the lower switches.
Push the assembly to the right position where the trigger
starts to touch the housing and tighten the screws.

STEP 9: CHECK THE SWITCHING SEQUENCE
Open and close the door very slowly, so you hear the ‘click’ noise of the switches three times. Also watch the
switches.
STEP 8: CONTINUED
Xcelerate™ Hi-Speed Oven
CHANGE DOOR SWITCH
When closing the door S2 must ‘click’ first, after that S1 and S2 should ‘click’.
S2 is the safety switch. If S2 does not switch before S1 and S3 switch (‘click’), a short circuit will occur and circuit
breaker F1 will trip. This mechanism is an international standard that disables microwave operation if there is a
malfunction of a switch or the adjustment is not correct.
If this type of short circuit occurs more than two or three times, switch S2 is likely damaged and must be replaced
again.
When you are sure the switch activation sequence is correct, you can apply power to the oven. Place a glass of water
in the oven, start a cooking sequence that includes the use of microwave power and slowly open the door. If all works
fine, open the door quickly. If the adjustment is correct the oven will work normally. If F1 trips while opening the door,
checktheswitchesagain.Alwaysdisconnectthemainpowerplugwhenworkingonthedoorswitch!
