VENTILATION CHECK
Your oven could be connected with one of the following connections
1. Exhaust Hood -*(Recommended Option)
The oven is located under a commercial
hood
2. Exhaust tube or Pipe
The oven is connected to an exhaust tube
ventilation system to the top front and top
back of the oven
3. No ventilation
The oven is not connected to a ventilation
system
Make these observations and cross all the boxes
4. Flue diverter
Be sure that the back flue diverter is
connected firmly to the oven
5. Flue diverter air circulation
Regardless of the connection, the flue
diverter base needs to be open at all times
6. Warning!
DO NOT place any object blocking the
ventilation. this affects the baking, oven
performance and may cause fire
EXTERNAL CONNECTION CHECK
Check external breakers or fuses
1. In your electrical circuit box, check and
identify the position of all the external
circuit breakers or fuses for the oven
2. If you have external circuit breakers.
Check that all the breakers are in ON
position. IMPORTANT! Call an electrician
if the breaker trip again

FUNCTION TEST
Test the function of the electric components
1. Turn main switch to position 1
2. Is the display dimmed and can OFF be
seen?
YES NOT
3. If NOT –Check if the black transformer is
rounded, if so is, this is broken due to
incorrect installation or a power surge
4. Check main circuit board: Measure
~volts between pole 1and pole 2 on the
green 8 pole connector on every deck, fill in
the next table
5. fill in voltage here
Deck5: (If available) __________V
Deck 4: (If available) __________V
Deck 3: (If available) __________V
Deck 2: (If available) __________V
Deck 1: (lower deck) __________V
6. Press ON/OFF button on deck 1 to start
the oven. Set all heat zones to 0, set temp
to 0 degrees. Power lamp and turbo lamp
should be off
7. Measure ~volts on all heaters (700
series = 10 heaters and 800, 900 = 14
heaters) there Should be no voltage
8. Observe that every heater has its own hole
cut out in the metal
9. Set all heat zones to 10, set temperature
to max. Power lamp should be on

FUNCTION TEST
Test the function of the electric components
10. Turn oven OFF and then ON again,
this activates the turbo function (voltage
to all heaters) Power lamp on and turbo
light should be on
11. Measure all heaters, there should be voltage
on all heaters, top and bottom
12. Measure Amps on incoming wires and note
them in point 13.
13. Compare with amps list in electric
schematic

amps draw in the electric schematic
see next step picture ----- →
15. Measure amps on all heaters
16. Set heat zone TOP to 0 and
BOTTOM to 0 this deactivates turbo
17. Increase TOP to 10 Power light should be on,
Upper heaters should have voltage, lower heaters
should have no voltage

CIRCUIT BOARD TEST
Test the function of circuit board
1. TURBO:
When starting the oven cold, TURBO function is ON. This is a function to reach the set temperature as fast as
possible. All heat zones are set to maximum and the Turbo Light is activated. When the oven reaches the set
temperature turbo shuts off, and the heaters works with TOP and BOTTOM configuration (See below)
2. HEAT ZONES
There are three heat zones in the oven.
Each zone has a contactor supplying power to the heaters.
TOP FRONT (Orange) –Two Top heaters at the front, Left
contactor
TOP (Blue) –Rest of the Top heaters, middle contactor
BOTTOM (Green)- Heaters under the stone, right contactor
3. TOP and BOTTOM Configuration:
You can set the TOP and BOTTOM heat zones from 1 to
10:
This means, when the Light Power is ON:
•Every heat zone has cycles of “50 Seconds”
•The 50 seconds are dived in 10 segments of 5 sec.
each
•During this time the elements at the TOP and
BOTTOM can be ON or OFF, depending on the
settings (see the graphic) on Green the Elements are
ON, in White the Elements are OFF
•For example:
-If you select 7 on the TOP: The element is ON
during 35 seconds and OFF 15 seconds
-If you select 3 on the BOTTOM: the element is
ON 15 seconds and OFF 35 seconds.
Check the Contactors:
•The contactors must be INACTIVE in OFF position
•The contactors must be ACTIVE in ON position
* We recommend to replace all the contactors at the same time and replace them after 5 or 6 years
4. TOP FRONT Zone:
It is possible to configurate the TOP FRONT zone from 0 to +4 with respect of the TOP zone.
See the example:
Press SET, to see the actual temperature and the configuration in the TOP FRONT zone.
If the configuration of the TOP FRONT is +2 and TOP is 7, you will have 9 at the TOP FRONT.
Factory Settings: as standard the factory settings are:
•For a pizza deck is: +2
•For a bakery deck is: 0
(normally equiped with a high deck and steam system)
INACTIVE ACTIVE
TOP FRONT TOP BOTTOM

4. Start the oven, set TEMP to MAX, set ALL
HEAT ZONES to “0”. This turns turbo off
and activates the software.
5. Start with TOP FRONT heat zone. Set
heat zone TOP to “5”and BOTTOM to “0”,
power light is active.
6. Press SET key to see the setting. Look at
the table to know the cycle times. Look at
the LEFT CONTACTOR and time the
active/inactive cycles with a watch to see
that the software works properly
7. TOP heat zone, Setting is TOP “5”and
BOTTOM 0. Look at MIDDLE CONTACTOR
and time the active/inactive cycles. Should
be approx 25 seconds active and 25
seconds inactive ac ording to the table
8. BOTTOM heat zone, set TOP to 0 and
BOTTOM to “5”. Look at RIGHT
CONTACTOR and time the active/inactive
cycles. Should be approx 25 seconds active
and 25 seconds inactive, all acording to the
table

PM 700 / 800 / 900
TEMPERATURE CHECK
Test the function of the temp sensor PT1000
1. We must know if the temperature shown on the display is correct and equal to real temperature.
The oven should be on for at least one hour before performing this test
2. How to check
In this example the temp. is set to 600 degrees Fahrenheit. Measure when power
light goes off
Top and bottom setting is 7, 1.
It´s very important to be accurate when measuring.
Always measure when the power light goes off.
This means that the oven has reached the SET temperature.
Quickly open the oven door and measure in the center
of the stone (s) with an Infrared thermometer.
The temperature on the stone surface should be about
30-40 degrees hotter than the SET temp, in this case
about 630-640 degrees Fahrenheit.
