KETTLE VENTING INSTRUCTIONS
RESERVOIR FILL
PROCEDURES
The kettle's water level must be maintained at the
proper level to submerge the heater elements. Under
normal operating conditions, the sealed water reservoir
should never require the addition of water.
If the red "low water" light comes on during use (while
the kettle is in an upright position), the water level has
reached a critically low level. The low water protection
control has automatically shut off the heater elements.
The following procedure must be completed before
further use:
NOTE: Have a qualified service technician repair the
leakage problem and add water to the unit. Ensure that
the red "low water" light is on when the kettle is upright.
On tilting kettles, it is normal for the red light to come on
when the kettle is in a tilted position, as the elements
are not submerged in water at this point.
DISTILLED WATER REQUIREMENTS
1. Ensure kettle is at room
temperature and pressure
gauge showing zero or less
pressure.
2. Shut off power to the kettle
at the fused disconnect
switch.
When Red “Low Water
Kettle Light” comes
Capacity on, add Distilled Water
25 gallon 1.0 U.S Gallons
30 gallon 1.5 U.S Gallons
40 gallon 2.0 U.S Gallons
60 gallon 2.1 U.S Gallons
80 gallon 2.6 U.S Gallons
100 gallon 2.8 U.S Gallons
1. Turn kettle ON and set
Temperature Control to 10
(Max.), heat the empty kettle
until unit cycles off.
2. Vent kettle by pulling safety
valve ring 8-10 times in short
2-3 second blasts with a 5
second interval between
pulls.
NOTE: If unit cycles ON, stop
venting and wait for kettle to
cycle OFF before continuing.
3. Turn kettle OFF. Add cold
water to kettle until its surface
temperature is below 100°F.
The pressure gauge needle
should be in the green zone,
indicating a vacuum in the
kettle’s jacket.
