2. 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).

3. 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.

4. Load the oven as fast as possible to avoid letting out too much heat.

5. 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.

6. 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.

timing the steam injection system.

OPERATION OF THE PROOFER

1. Switch "ON".

2. Set the thermostat control at 100oF.

3. Set the humidity control at approximately : 4 or 5 for CAOP6 and CAOP12

4. If there is too much fog and water drips from the glass doors, adjust humidity control to a lower

number.

5. When the temperature is stabilised, put the products in the proofer.

(Leave them inside until they are ready to bake.)

6. 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.
