TECH TIP: SPE-DEX® 4790 Automated
Extractor System
SPE-DEX® 4790 Extractors
Replacing Thermistors / Thermistor Assembly
Step 1) Remove the five- (5) 6/32 Phillips screws
located in the back panel of the Extractor.
Step
2) Remove the cover, by holding the bottom of the side
panels, and push the bottom toward the back of the unit.
Then lift up. Set the cover aside.
Step 3) Before removing the thermistor clip, note
the orientation of the clip and the heights of the thermistors.
The thermistor on the right (as you face the unit) is the
top sensor, and the thermistor on the left is the bottom
sensor. For later reference, note the spacing difference
between the two black sensing elements of both thermistors.
Step 4) Remove the Thermistor Assembly clip from
the Downtube by sliding the clip down and off. The platform
can also be lowered to make it easier to remove the sensor
clip.
Step 5) Follow the electrical lines from the Thermistor
clip to the Extractor circuit board. There will be two,
two-prong Molex connectors attached to the main electrical
circuit board. The top thermistor will be attached to pin
J6 and the bottom thermistor will be attached to pin J7.
Pin J6 is the closest to the front of the circuit board,
while pin J7 is the closest to the back of the circuit board.
Replace the thermistors one at a time pulling the wire out
through the slot in the front face of the chassis.
Step 6) Hold the open sides of the Thermistor clip
between two fingers, and gently squeeze the clip. Squeezing
the clip reduces the tension holding the thermistor in position.
Gently slide the thermistor out of the clip. While squeezing
the clip, gently slid the new thermistor into the clip thermistor
groove. Adjust the height of the replaced thermistor to
match the positions before the thermistor was removed.
Step 7) Guide the electrical wire with the two-prong
Molex connectors through the face of the Extractor where
the Prewet lines are coming out. Connect the two-prong Molex
connectors to the appropriate location on the electrical
board.
Step 8) Carefully slide the Thermistor clip onto
the Downtube and up to a middle position on the Downtube.
Finally adjustment can be made once a Disk Holder is in
position.
Step
9) Replace the cover by sliding the cover down and pulling
the bottom of the cover towards the front of the Extractor.
Note the tabs on each side of the cover go inside the front
panel.
