Sequen ce o f Op er ati o n
The fol lowing “a ction-reaction” outline is provided
to help the user understand how the equipment
works.
When the operat or start s up the k ettle by tur ning
the opera ting th ermostat dial from “OFF” to a
desir ed setti ng, th e thermostat switch closes.
This lights up the heating indicator light and
causes the contactors to close, allow ing power
to flow to heating elements. When the
temperatur e of the st eam jacket r eaches the
value corresponding to the dial setting, the
thermostat switch opens. Thi s turns off the
heating indicator light and causes the contactors
to open, stopping the power to the heaters. As
soon as the thermostat senses that the kettle is
cooling below t he set point, the thermostat
switch closes, the heati ng indicator light comes
on, th e contact ors close, and the heater s com e
on again . On-off cyclin g contin ues, keeping the
kettle at the set temperature This is why th e
heating indicat or light cycl es on and off du ring
normal operation. Every time the kettle is tilted,
the tilt cut- off switch int errupts t he power supply
to t he heat ers, so that the heati ng element s will
not operate w hile no t submerged in th e jacket
water.
If steam pressure greater than 50 PSI is
generated in the jacket, the safety valve will open
and relieve the excess pressur e.
In the event that the jacket water level gets too
low and the heating element s overhea t, t he high limit control will open and shut off power to t he
elements until the kettle cools. Setting the
operating ther m ostat dia l to “OFF” sh uts down al l
control and heating circuits.

At least twice a year, grease the two
trunnion bearings. The bearings are located
within the kett le support h ousing. R em ove
the access panels from the support housing
with a screwdriver to gain access to the
grease fittings. Use a lithium-based, multipurpose grease. When the access panels
are removed, the mounting bolts for the
trunnion bearings and tilt switch can also be
checked for t ightness. When finished,
reassemble access panel s to support
housing.
Jacket Vacuum
2.
When the kett le is cold, a positive pressur e
reading or a reading around zero on the
pressure/ vacuum gauge indicates th e
presence of air in the jack et. Ai r in the jack et
slows down the h eating of the kett le.
To remove air:
a. Start the unit. (See the “Operation”
section of this manual.) (Be sure there is
water or product in the kett le when
heating).
b. When the pressu re/va cuum gauge
reaches a posit ive pressur e readin g of 5
PSI, r elease t he tra pped air and steam

LABEL OF THE WATER TREATMENT
COMPOUND.
(1) Fill the mixing container with the
measured amount of water required.
(See t he tabl e at right) . Dist ill ed water is
recommended.
(2) Hang a str ip of pH test pa per on the rim
of the container, with about 1 inch of the
str ip below the sur face of th e water .
(3) Measure the water treatment compound
you will be using. (One way to do this is
to add the compound from a measuring
cup.)
(4) Stir the water continuously, while you
slowly add water t reatment compound,
until t he water r eaches a pH between
10.5 and 11. 5. Judge the pH by
frequ ently com parin g the col or of the test
str ip with th e color chart provided in the
pH test kit. Color blind people mi xing the
treated water solution must use an
electroanalytical instrument to measure
the pH level or have a person that is not
color blind read the test strip color level.
(5) Record the ex act amount s of water and
tr eatment com pound used. These
amounts may be used again, if the same
sources of water and compound are
employed to refill the jacket in the future.
However, it i s advisa ble to check t he pH
