MAINTENANCE CAN CAUSE PROPERTY DAMAGE, INJURY OR DEATH.
READ THE INSTALLATION, OPERATING AND MAINTENANCE INSTRUCTIONS
THOROUGHLY BEFORE INSTALLING OR SERVICING THIS EQUIPMENT.
Installation and service must be done by specialised technicians. Contact a certified electrician and
plumber for set up.
The oven must be connected to the utility and electrically grounded in conformity to the effective
local regulations. If these are not established, the oven must be connected according to the Canadian
Electrical Code (CSA-C22.1-XX) or National Electrical Code (NFPA 70-XX). Refer to last
edition year for XX. Installation must also allow proper access for service (24 inches each side and
back).
The ovens must be installed with a proper ventilation according with the local building code.

A4
DISTANCES TO RESPECT
A) Back and sides of the oven: 1 inch.
B) Top of the oven: a clearance of 12 inches to the ceiling must exist to permit adequate venting.
C) Floor: 4 inches minimum.
D) Sides of the oven: do not install other than easily removable equipment for service and
maintenance (not closer than 1 inch).
E) It is recommended to have a certain length of water pipe, electric cable between oven and
wall to help gain access for service.

A5
INSTALLATION
IN GENERAL
Take off the packaging material with care. Take off all the material used for packing and accessories.
1. To the electrician
Electrical supply installation must be in accordance with the electrical rating on the nameplate.
WARNING
The electrician must make sure that the supply cable does not come in contact
with the oven top which becomes hot.
2. To the plumber
This equipment is to be installed to comply with the applicable federal, state or local plumbing codes.
Connect the steam system (1/4 NPT) to the cold water distribution network.
We highly recommend to use a water softener to eliminate minerals in the water. We suggest you to
use CUNO # CFS6135 (Doyon part number PLF240).
WARNING
Do not adjust the needle valves, it has been done at the factory.

A6
OPERATION OF THE OVEN
1. Turn the switch to the " ON " position.
•The light inside the oven must light up.
1. Adjust the thermostat at the desired setting (see THERMOSTAT INSTRUCTIONS below).
N.B. The red light must be "ON" (If not, press the breaker on the front).
1. Heat the unit until you reach the baking temperature.
When the desired temperature is reached, the red light goes out and turns green.
If the light is still "ON" and the oven does not produce heat, call for service.
1. Load the oven as fast as possible to avoid letting out too much heat.
1. Set the timer to the desired value and start it. (See "TIMER" adjustment on next page.)
NOTE: The timer does not shut the oven off at the end of its cycle. It simply activates the buzzer.
1. Wait until the product is ready. Do not open the doors until the product is done.
VERY IMPORTANT
This oven has an overheat warning alarm to protect the electrical components against overheating. If
the red pilot light (OVERHEAT WARNING) is lit and you hear a buzzer, see troubleshooting.
THERMOSTAT INSTRUCTIONS
To obtain a very good thermal stability, we use a digital temperature controller with thermocouple.
The Omron E5CS thermostat controls the heat of every element at the SP (set point).
The temperature of the oven is always shown on the display of the thermostat and an arrow indicates
if the temperature is over or below the SP. When the green light is lit, it indicates that the temperature
is at the SP ± 1 %.
To adjust the SP (set point) value, you just have to press the key on the left and use the up and down
keys to set the temperature. Press the left key to return to run mode.

INSTRUCTIONS FOR OVEN
BAKING
350oF (Croissants, Sweet doughs, Small rolls)
375oF (Baguette bread, round loaf, 10 oz. bread and more)
375oF (If the oven is filled to its capacity)
Place products in the oven only when the pilot light has gone out.
OPENING AND CLOSING OF THE DOORS
To open the doors: Open one of the doors up to 2" and wait 2 seconds to let the fan reduce its
spinning before opening completely.
To close the doors: Close the first door completely and the second door down to 2" and wait 2
seconds before closing completely and then hold the door closed for 2 seconds.
P.S. Open the doors as little as possible. This will affect the baking.
COOKING TIMER H5CL
Set the baking time required with the small push button on the timer. The green display is the setting
time and the red display is the countdown time (Ex: 25 minutes = set 2500 on green display).
After setting: Push the START/STOP button then, when the time expires, the buzzer will ring. Push
the START/STOP button again to stop the buzzer.
If you want to restart the time in the middle of the countdown, press on the yellow RST button on the
timer.
P.S. The timer is simply a reminder for the approximate duration of the baking time.
STEAM TIMER H3DE
VERY IMPORTANT
Steam injection will only work when the ventilator of the oven is working.
To inject steam in the oven, press and release the STEAM TIMER button. The light comes on
inside the steam button during the steam injection. Steam injection has been factory preset. To have
more steam, press steam button a second time, after the light is off.
P.S. Do not inject steam more than once each time you bake. Wait at least 10 minutes before re-
timing the steam injection system.

A8
OPERATION OF THE PROOFER
1. Switch "ON".
1. Set the thermostat control at 100oF.
1. Set the humidity control at approximately : 3 for JAOP-3 & JAOP-6
4 or 5 for JAOP-10
5 for JAOP-14
1. If there is too much fog and water drips from the glass doors, adjust humidity control to a lower
number.
1. When the temperature is stabilised, put the products in the proofer.
(Leave them inside until they are ready to bake.)
1. IMPORTANT : When proofing cycle is completed, turn the humidity switch to "OFF" and
let the motor blower and air heat element run for 10-15 minutes to let dry the proofer. Then, turn
the main switch off, and leave the door ajar to prevent moulding.
When the proofer is not in operation, open the doors to let out the humidity and to prevent
mould.
P.S. The doors should not be opened unnecessarily to conserve the heat and humidity in the
proofer.
Every day cleaning of the water pan under the proofer's doors should be exercised.
