Introduction

DESCRIPTION

Each model has a jacket of double-wall construction
forming a sealed reservoir around the lower two-thirds of
the kettle. The reservoir is charged with distilled water.
Kettles are equipped with a removable electric heating
element and controls, including a low water cutoff device
for protection of the heating element. All models are of
identical construction, except for kettle size and element
heating capacity.

BASIC FUNCTION

Self-contained kettles operate by generating steam in the
kettle reservoir. The sequence of operation is as follows:
1. Operator turns the power switch to the ON position
and sets the temperature control dial to the desired
temperature setting.
2. Control circuit is normally completed to the tempera-
ture controller if the following conditions exist:
a. Water level in the kettle reservoir is adequate to
prevent circuit interruption by the low water cut-
off device. An activated cut-off is indicated by the
amber low water light turning on, and the heating
element shutoff.
b. Kettle is in vertical position with circuit completed
through the tilt interlock switch.
3. Thermostat control contacts close to energize contac-
tor coils.

OPERATION

4. Power is supplied to the elements through closed
power contactors.
5. As the temperature of water rises in the kettle reser-
voir, increase in steam pressure is indicated on the
pressure gauge.
6. When the temperature of steam in the reservoir
reaches the setting of the temperature control dial,
the temperature controller opens to break the con-
tacts and shuts off the heating element. On/off cycles
will occur as required to maintain temperature setting.
