before starting - important!

Send an email to support@roestcoffee.com with your order number, production number, and machine name. This information is needed in order to give your machine access to the inlet profiles. Production number and machine name can be found on a sticker at the front of your roaster.

 

Part 1 - assemble the inlet temperature kit

Unpack the temperature probe. Install the gasket on top of the probe and insert it through the holes in the new housing on the flat side. Push it on until you hear a click. Use the two screws to tighten it into place, but don’t overtighten it as the white piece can break.


part 2 - install the inlet temperature

1. Take off the top plate.

2. Remove the right-hand side panel.

3. Take off the front décor plate.

4. Only for L100, remove the k-type cable from the PCB. Free the cable from the heater fan.

When you remove the drum temp sensor, leave the connector wide open. The connector on the right is in the correct position, and the connector on the left is in the wrong position.

5. Disconnect the heater fan from the PCB and cut the cable ties holding the cables from the heater fan in place.

6. Disconnect the heating element cables from the wago connectors. Undo the two screws on the heating element lid with a 2.5-millimeter hex key, and lift the heating element away from the housing. Put it aside. NOTE: Before disconnecting, take a photo or make a reference to ensure that the correct cable goes into the correct wago connector when reconnecting. Remove the silicone hose.

Only open the two flaps that read Wago 221.

7. Remove the six cap head bolts holding the heater fan with the 3-millimeter hexagonal tool.

8. Remove the old heater fan assembly. To do this safely and correctly, follow these steps:

1. Push the heating element housing towards the drum (this will tilt the assembly at approximately 45˚).

2. Pull the heater fan assembly out while maintaining the 45˚ angle. Pull the drum temperature sensor cable out from the holes in the heater fan.

8. Remove the superwool bracket and the superwool. 

Superwool and bracket

9. Remove the heating element housing from the heater fan by loosening the following three screws.

The tool you received with your kit should be long enough to reach this screw.

Leave the bolts loose like this, do not remove them yet.

Slide the housing away from the two front bolts.

Slide the housing away from the two bolts; now, the housing is free to be removed. Lift the housing upwards to remove it.

10. Remove the old inlet housing and install the new one with the inlet temperature.

Remove the mica tube by pulling it out.

Undo the three bolts and remove them.

Remove the spacer from the old inlet housing.

Install the spacer on the new inlet housing by leaving all three screws loosely done.

Leave space between the bolts and the housing.

Slide the heater fan on the new inlet housing, push it forward until the heater fan covers the spacer, and tighten the three screws. Install the mica tube again.

11. Install the heater fan with the new inlet temperature.

Cut the super wool in half.

Slide the inlet temperature probe through the slit while lifting up the superwool.

Slide the heater fan in place.

Make sure there is no gap.

Loosely install the six head bolts holding the heater fan in place. With the bolts loose, push the heater fan as close as possible to the drum, then tighten the four outermost bolts. Install the super wool and the bracket, tightening the remaining two bolts. Reinstall the heating element.

Push the bracket down as much as possible and make sure the screws secure the bracket.

Make sure the orientation of the heating element is correct. The red rubber component should be closer to the PCB.

12. Install and connect the cables.

Find the two k-type sensors and pull them out towards you, so they are easily available; the inlet temperature sensor will be marked with black tape so you can easily recognize it.

Pull the drum and inlet sensors through the two holes in the heater fan.

Install the drum and inlet temperature sensors in the screw terminals. Ensure that the drum and inlet are installed into the proper terminals and that the polarity is correct. The right positions are shown in the photo above.

Reconnect the heater fan and the heating element cables (use the reference photo you took at the beginning to ensure they are inserted correctly). Reinstall the orange hose for the exhaust. Use the new cable tie where you cut the cable tie at the beginning of the process.

13. Install the front décor plate. Instructions here.

Small ratchet

Parts

ET sensor

Cable ties

Tray, or similar, to keep removed components

Instructions

Follow this numbered guide below step by step.

1. Remove the top plate.

2. Remove side panels.

3. If your roaster has First Crack detection, remove it by pulling it gently and disconnecting the cable from the PCB.

4. Using the 12-millimeter wrench, remove the proximity sensors from the drop door. These can be left cabled into the roaster but moved out of the way for easy access. 

 

5. Remove the charge handle.

 

6. Remove the exhaust pipe from the bean stopper exhaust (top) and chaff separator (bottom). 

7. Using a 6-millimeter wrench, remove three off black First Crack “grommets”. 

8. Remove the M4 x 6 Cap head screw holding the bean-stopper using the small ratchet with a 3-millimeter hexagonal tool bit.

9. Using a 3-millimeter hexagonal key, loosen and remove four off M4 x 6 cap head screws retaining the bean-stopper in position. 

 

10. Once the screws from steps 8 and 9 have been removed, tilt the exhaust duct from the bean stopper upwards and pull the bean stopper out.

This will give you a clear view inside the roasting drum to install the new ET sensor. 

 

11. Unplug the ET sensor from the PCB. 

 

12. Cut cable ties holding the cable in place (two). Use the cutters.

13. Use a 10-millimeter spanner/wrench to loosen the M6 hexagonal nut holding the ET sensor in place. 

14. Remove the ET sensor. 

 

15. Take the new ET sensor and screw the M6 hexagonal nut onto the thread. The sensor should have a blacked-out area to indicate the length at which the sensor should be positioned in the drum.

 

16. Screw the ET sensor into the back plate. NOTE: Please ensure no resistance when rotating so as not to damage the thread in the back plate. 

 

17. Before fastening, the orientation of the sensor is critical for it to work. From the front of the roaster, the orientation of the sensor must be as follows: The blue stripe should be on the right, and the white stripe in the middle should be completely vertical. If this criterion is met, fasten with the 10-millimeter wrench.

 

18. When fastening the sensor, ensure that nothing of the black area is visible inside the drum; if it is, you have screwed the sensor too far in.

19. If the criterion from steps 17 and 18 have been met, the nut can be tightened. Do not move forward until the orientation and length of the sensor have been set correctly.

20. Plug the ET sensor into the original spot on the PCB.  

 

 21. Tie two new cable ties to the motor bracket where you removed the cable ties earlier.
