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).
WARNING: THE FUSED DISCONNECT SWITCH MUST BE
OFF BEFORE REMOVING THE KETTLES BOTTOM COVER.
Draining procedure
1. Pull pressure relief valve to insure there is no pressure
within the kettle jacket.
2. Remove bottom covers.
3. Remove low water level probe and allow water to drain.
4. To rinse kettle jacket:
a) On tilting kettles fill jacket from low water probe fitting.
b) On stationary kettles:
1. Replace low water probe.
2. Remove pressure relief valve and replace with
street elbow.
3. Using a small funnel (one made of paper works
great) slowly pour water into the kettle.
5. Allow kettle to drain again.
6. Repeat until water drains clear.
REFILLING UNIT
1. Apply a thread sealant (i.e. Teflon tape) to the water level
