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.
CAUTION: Only a mixture of distilled water and rust inhibitor should
be used when adding water to a partially filled water reservoir. Local
tap water conditions may cause kettle damage which is not covered
under warranty. Rust inhibitor is purchased locally. Read directions
and do not exceed manufacturer's recommendation (excessive rust
inhibitor can also cause solidification).
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.

1. Remove guard bracket from
pressure relief valve/gauge
assembly.
2. Turn kettle ON and set
Temperature Control to 10
(Max.), heat the empty kettle
until unit cycles off.
3. 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.
4. 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.
5. Replace guard bracket from
pressure relief valve/gauge
assembly.

(See Repairing Leaks in Steam Jacketed Kettle Fittings
on page 19).
