RESERVOIR FILL PROCEDURES
The kettle's water level must be maintained at the proper
level. 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 gas burner. 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.
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.
3.
Remove Console Cover and Access Panel.
4.
Pull Pressure Relief Valve Ring open
to insure vessel is not pressurized.
5.
Remove 1/4" copper tubing and
reducer bushing.
6.
Add distilled water using a funnel if
necessary. Fill the unit to the high
level mark on the Sight Glass.
7.
Apply a thread sealant (i.e. Teflon
tape) to the reducer bushing threads
and replace.
8.
Replace Console Cover and Access
Panel.
9.
Restore power to unit at the fused
disconnect switch.
