Electrical Connections
Connect the electrical heating service to the still as
shown in Figure 14. The heating service terminal
board is located inside the junction box at the base
of the still. Customer must supply adequate on-off
control for electrical heating service.
Make the electrical connection to the terminal
board in the low water cutoff control cabinet as
shown in Figure 9 and in accordance with the fol-

1.
Remove the low water cutoff cabinet front
panel. To remove the panel, remove the
two lower screws in the front of the cabi-

the cabinet. The panel fits tightly in the
cabinet. Do not attempt to pry the panel
from the cabinet.
2.
Connect the low water cutoff probe wires
to terminals 1 and 2 with #18 AWG strand-
ed wire. Connect the outer shield wire of
the probe to terminal #1 and the center
wire of the probe to terminal #2. Solder
and tape the connections. At the evapora-
tor both wires should protrude through the
grommet in the probe shield which is
secured in place with 2 screws over the
cutoff access hole in the evaporator cas-
ing.
3.
Connect the still heat control contactor coil
to terminals 6 and 11.
4.
Connect a 3-wire, 115-VAC, 60-hertz elec-
trical service to terminals 9 (AC high), 7
(AC low), and the ground screw just below
the terminal board. This electrical service
will provide control voltage for the low
