To ensure the proper, long-lasting and safe functioning of the equipment, service twice a year by
qualified personnel from our company, and especially:
- Dismantle burners, checking and cleaning venturis.
- Clean the nozzles.
- Clean the ventilating apertures.
- Investigate possible leaks.
- Check controls, regulation and safety systems.
- Check the hydraulic circuit and condenser.

7. VERIFICATION OF TEMPERATURE SENSORS
SENSOR PT100 (1 point for the capacity sensor, 1 point for the core probe)
Components of the sensor PT100
PT100
Temperature sensor composed of a resistance sensor with the value of 100 ohms for a temperature of
0°, 138.5 ohms for a temperature of 100°. The varia tion of the resistance depending on the temperature is
linear. The reading of the resistance gives directly the measured temperature. The sensor is not polarised.
The sensor is lengthened by a copper wire.

How to read the chart:
To find the resistance corresponding to the temperature of 164°C.
Find the intersection of the line 160°C and the col umn 4°C.
The reading shows 162.53 Ohms.
Check
Ω
PT100
MΩ
Check sensor resistance with an ohmmeter gauged at 200 ohms (less than 107 ohms for 20°).
Check the sensor insulation between one of the leads and the metal part with the ohmmeter gauged at
20 megohms (a value over 15 megohms).
Check the continuity between the screen and the metal part of the sensor.

8. DOOR ADJUSTMENT AND CLOSING
WARNING: This adjustment must be carried out everytime the door or the door closing system is serviced
(hinges, closing device...), or after a steam leak in the way of the capacity seal.
8.1 8 AND 12 LEVEL OVENS
- Check that the oven is levelled.
- Door closed. Level the door by unscrewing both fixation screws of the upper hinge on the oven.
- Level the door, tighten and block the screws.
- Loosen the fixation screw of the upper hinge on the door.
- Push the door against the seal so that tightness is perfect. Warning! It is useless to squeeze the seal
flat, it will not result in better tightness.
- Block the fixation screw of the hinge.
- Bring the upper distance between the door and the capacity to the lower part of the door by loosening
the fixation screws of the lower hinge.
At this stage, if the procedure has been properly executed, the door should be at the same height as
the oven top. If not, readjust before the next step

- open the door and measure the distance between the door top and the tip of the closing piston.
- Measure the distance between the top of the oven and the bottom of the hook groove.
Distance between the top and the piston tip Distance between the top and the groove bottom
- The distance between the top of the oven and the closing hook must be 1 to 2 mm greater than the
distance between the top of the door and the piston tip. If not, loosen the closing hook screw and adjust
the distance.
8.2 20 LEVEL OVENS
- Make sure that the oven is properly secured to the floor. Level the oven.
- Door closed. Level the door by unscrewing both fixation screws of the upper hinge on the oven.
