B.
Open the water shut-off valve.
C.
Open the water throttling valve about 1/2 turn.
D.
When the water level in the evaporator reaches a sufficient level, as indicated by a steady overflow to waste,
connect the still to the electrical service.
CAUTION: ENSURE THAT THE WATER LEVEL IN THE STILL EVAPORATOR IS ABOVE THE HEATING ELEMENTS
BEFORE CONNECTING THE STILL TO THE ELECTRICAL SERVICE. THE HEATING ELEMENTS ARE THE
IMMERSION TYPE AND WILL BURN OUT IF OPERATED IN AIR. THE WATER WILL BE AT A SAFE LEVEL WHEN
WATER OVERFLOWS TO WASTE.
E.
When the still begins to produce distilled water, adjust the water throttling valve until just a puff of steam issues
from the condenser vent. Discard the first 2 hours of distillate production to allow the still to clean itself out.
NORMAL OPERATION
Starting. Start the still as follows:
A. Close the drain valve.
B. Open the water shut-off valve.
C. When water overflows to waste, connect the still to the electrical service.
CAUTION: ENSURE THAT THE WATER LEVEL IN THE STILL EVAPORATOR IS ABOVE THE HEATING ELEMENTS
BEFORE CONNECTING THE STILL TO THE ELECTRICAL SERVICE. THE HEATING ELEMENTS ARE THE
IMMERSION TYPE AND WILL BURN OUT IF OPERATED IN AIR. THE WATER WILL BE AT
A SAFE LEVEL WHEN WATER OVERFLOWS TO WASTE.
NOTE: If the still is operated continuously, it should be stopped and drained once every 4-hours. Draining the still at
frequent intervals will help to inhibit the formation of scale in the evaporator.
Stopping. Stop the still as follows:
A. Disconnect the still from the electrical service.
B. Close the water shut-off valve.
C. Open the drain valve to allow the still evaporator to drain completely while its contents are hot.
CAUTION: ALWAYS DISCONNECT THE STILL FROM THE ELECTRICAL SERVICE BEFORE SHUTTING OFF THE
WATER SUPPLY.
NOTE: Do not change the setting of the water throttling valve.
CLEANING
CLEANING METHODS. Cleaning requirements fall into two classes: scale removal and biological cleaning. Scale
removal may be accomplished chemically or mechanically. biological cleaning is accomplished with a formaldehyde
solution. For best results alI solutions and water should be heated. The various methods of cleaning are as follows:
