5. Remove the two nuts from the new door closed sensor (one nut
is not needed).
NOTE
Replacement sensors are shipped without the connec-
tor body (P331) attached.
Do not install the connector
body to the wires of the door closed sensor until the
sensor has been installed (step 7).
6. Lightly lubricate the threads of the new door closed sensor. This
will permit easier installation.
7. Install the new door sensor as follows:
a. Place the back-up nut on the top of the sensor bracket.
b. Guide the door closed sensor wires through the hole in the
cabinet, the back-up nut and the bracket. While holding the
back-up nut (so that it is not touching the bracket), thread
the sensor through the nut and the bracket until the top of
the sensor is flush with the cabinet. Tighten the back-up nut
against the bracket.
c. Insert the pins at the end of the sensor wires into the connec-
tor body (P331, supplied). Pins should click into place and
not pull out.
d. Reinstall the sensor plug cover.
8. Reinstall the bezel, then plug in the centrifuge power cord.
5-7. Fuse Replacement
The fuses are replaced by removing the fuse block located in the
power connector on the back of the TC6
®
(see figure 5-3).
To replace the fuses:
1. Unplug the power cord from the wall receptacle and from the
power connector.
2. Squeeze the two tabs located on either side of the fuse block and
carefully remove the fuse block from the power connector.
3. Gently pull the damaged fuse(s) from the fuse block. Discard.
4. Install only properly rated fuse(s). Fuses are Type T, 250 V, but
change amperage rating depending on the voltage selected:
• 100 - 120 setting requires two 3.15-amp fuses (PN␣91428)
• 220 - 240 setting requires two 2-amp fuses (PN␣91203)
C A U T I O N
When removing fuses, do
not remove the voltage selector from
the fuse block (SN 9501733 and be-
low only). To do so can alter voltage
compatibility (refer to paragraph 2-4,
Voltage Selection).
