Frequently Asked Questions - JA4SC Doyon
How to set the temperature on the JA4SC oven?
Use the digital Omron E5CS thermostat. Press the left button to select the SP (set point) variable, adjust the value with the arrows, then press the left button again to return to normal mode. The green light indicates the temperature is within ±1% of the set point.
How to inject steam into the oven?
Make sure the oven fan is running. Press and release the steam timer button. The indicator light turns on during injection. For a longer time, press a second time after the light goes out. Do not inject more than once per cooking cycle and wait at least 10 minutes between injections.
What to do if the oven does not heat?
Check the circuit breakers on the oven front panel and those of the building. Make sure the doors are properly closed. If the motors are running, check the thermostat setting. If the motors are not running, check the overload relays in the rear control box. If a relay is tripped, contact a qualified technician.
How to clean the interior of the oven?
Use water and a mild detergent. Remove the grids and clean them with Easy-Off if necessary. Apply a silicone protector (ref. EXS400) to the walls and grids to prevent food from sticking. For the windows, use Brasso or an oven glass cleaner (ref. EXC300).
How to correctly open and close the doors?
To open: open a door 2 inches, wait 2 seconds for the fan to slow down, then open fully. To close: close the first door completely, then the second to 2 inches, wait 2 seconds, then close it completely. Hold closed for 2 seconds. Avoid opening doors unnecessarily.
What to do if the overheat alarm triggers?
If the 'Overheat Warning' indicator light is on and a buzzer sounds, check that the cooling fan ventilation duct is not obstructed. Also check the fan operation. If it is not running, call a qualified technician to replace it.
How to program a cooking menu with the Watlow controller?
Press both arrows simultaneously for 5 seconds to enter programming mode. Select the menu number (1 to 12). Set successively SP (temperature), t (time), and E (event: 0001=steam, 0010=buzzer, 0000=none). To exit, press #12 then CLOCK twice. Menu #1 is reserved for preheating without steam.
How to use the H5CL cooking timer?
Set the desired time with the buttons below the display (e.g., 25 minutes = 2500). Press the Start/Stop button to start the countdown. At the end, the buzzer sounds; press Start/Stop again to stop it. To restart before the end, press the yellow RST button. The timer does not stop heating.
What to do in case of a power outage?
Set the oven selector to OFF to protect electronic components when power returns. The oven will automatically restart on menu #1 if the selector remains in the ON position, which can be dangerous.
How to replace the bulb of the steam timer button?
Unscrew the front luminous cap of the button to access the internal miniature bulb. Replace it with an identical bulb. If the indicator light does not turn on but steam works, the bulb is likely burned out.
