Heating Element Test and
Replacement
Whenever a heating element is suspected of not
operating properly, test and if necessary, replace
the heating element as follows:
1.
Shut off the still. Close the water supply
valves to the still. Open the drain valve
and let the still drain completely.
2.
Disconnect the electrical heat supply to
the still terminal block.
3.
Remove the bottom plate from the still
evaporator. Disconnect the electrical
leads and bus bars from the heating ele-
ment terminals. Tag the leads to facilitate
reassembly.
4.
To test each heating element for open
circuit, apply a current across the
terminals. Use a test light in series with
the applied current. If the test light does
not light, the heating element is burned
out. Mark all damaged heating
elements.
5.
To test each heating element for short
circuit, connect one test lead to the boiler
bottom and the other to each terminal
(one at a time). If the heating element is
short circuited, the test light will light.
Mark all damaged heating elements.
6.
Remove the evaporator cover from the
still and inspect the heating elements
from the inside of the evaporator.
