220 volt AC Conversion
Split primary windings permit easy conversion
from 120 volt to 220 volt operation.
5. Solder a jumper to TB1 connecting the grey
and violet transformer wires.
6. Solder the black and white power lead-in
wires to the brown and white transformer
wires, respectively, on TB1.
7. Re-attach the top cover.
8. Replace the 6-amp, 250V fuse in the unit
with the 4 amp, 250V fuse, Part # 451-1003,
supplied with the 220-volt conversion kit,
Part # 105-1005-1.

100-VOLT AC CONVERSION
To convert the Model 250 to 100-volt operation,
follow the procedure outlined for 220-volt conver-
sion, except for items 5, 6, and 8. Item 8 is elimi-
nated. These items will read: `
5. Solder two jumpers to TB1, one connecting
the orange and violet transformer wires, and
one connecting the grey and white trans-
former wires.
6. Solder the black and white power lead-in
wires to the orange and white transförmer
wires, respectively, on TB1.
The Model 250 is now ready for 100-volt
operation.
