BX bakeout band
2.3 Installation
2.3.1 Unpack and inspect
Remove all packing materials and protective covers and check the BX bakeout band.
If the BX bakeout band is damaged, notify your supplier and the carrier in writing within three days; state the Item
Number of the BX bakeout band together with your order number and your supplier's invoice number. Retain all
packing materials for inspection. Do not use the BX bakeout band if it is damaged.
2.3.2 Fit the BX bakeout band to the pump
1. Switch off the pump, isolate the pump controller from the electrical supply (on an EXT DX pump, isolate the
podule from the electrical supply), and wait until the pump has stopped rotating.
2. Fit the BX bakeout band over the pump-body below the inlet-flange at the position shown by Figure 1, item 16 or
Figure 2, item 12.
3. Tighten the clamping-screw.
2.3.3 Electrical connection to an EXC controller
The BX bakeout band is supplied with a 3 metre cable terminated with an IEC connector. The connector fits the rear
panel socket on the EXC120, EXC300 and EXC300M Controllers.
If you have an EXDC or EXC100 Controller, or you have an EXT DX pump, you must use either a TIC Relay Box as
described in Section 2.3.4, or an independent electrical supply as described in Section 2.3.5.
1. Check that the rating of the fuse fitted in the rear-panel of the EXC Controller corresponds to the fuse rating
stamped on the BX bakeout band. (Two spare fuses are supplied with the BX bakeout band).
2. Insert the connector into the socket in the rear of the EXC Controller.
3. Refer to the EXC Controller instruction manual to complete the installation.
2.3.4 Electrical connection to a TIC relay box
Refer to the TIC Relay Box instruction manual for information on how to fit the correct fuse, and how to connect the
bakeout band to the TIC Relay Box.
2.3.5 Electrical connection to an independent electrical supply
If necessary, you can connect the BX bakeout band directly to an appropriate electrical supply.
Always ensure that the electrical supply to the BX bakeout band is interlocked so that it is automatically switched
off whenever the EXT pump operates below normal speed. Check that the rating of the fuse fitted within your
electrical supply corresponds to the fuse rating stamped on the BX bakeout band.
