NOTE:
If you are using pumps (with or without the Pump Module), you will need to
replace them with pumps configured for the new voltage.
NOTE:
Although the voltage selector is located in a housing termed "fuse drawer",
it contains no fuses. The fuse drawer contains a spring and a blank. Be sure
to keep these intact and in place when you reinstall the fuse drawer.

Changing PCU Fusing

If you are changing the voltage on your Power Controller, it may also be necessary to
modify the fusing arrangement on the PCU.
NOTE:
Be sure to discuss this with your NBS representative before a qualified
technician makes any modifications to the unit.
12.4.1
Your BioFlo 110 PCU was initially set up with a single fuse arrangement. To
change to a double fuse:
1. Open the cover of the power module using a small blade screwdriver and
remove the cover/fuse block assembly (see Figure 47 below).
2. Loosen the Phillips screw behind the fuse block 2 full turns(see Figure 48
below).
3. Remove the fuse block by sliding it up and away from the screw shaft and
lifting it off the pedestal (see Figure 48 below).
4. Invert the fuse block and slide it back onto the Phillips screw and pedestal.
Tighten the Phillips screw.
