OPERATING PROCEDURE

1. To Start Kettle Heating with Classic Controls:
a. EVERY DAY make sure that the jacket water level in the middle of the sight
glass. If the level is too low, see "Jacket Filling and Water Treatment" in
this manual.
b. Check the pressure/vacuum gauge. If the gauge does not show -20 to -30
inches of mercury (Hg) vacuum or a range of -0.7 to -1.0 Bar, see "Jacket
Vacuum" in this manual.
c. Turn on the electrical power to the unit.
d. Turn on the main power switch on the control face.
e. Turn the temperature knob to the desired setting. The heating indicator
light indicates that the kettle is heating, and cycling of the on and off
indicates that the kettle is being held at the set temperature. Once in each
cycle the contactors in the support housing will make a clicking sound.
This is normal.
2. To Start Kettle Heating with Advanced:
a. EVERY DAY make sure the jacket water level is above the mid-point of the
round sight glass. If the level is too low, see "Jacket Filling" and "Water
Treatment" in this manual.
b. Check the pressure gauge. If the gauge does not show -20 to -30 inches
of mercury (Hg) vacuum or a range of -0.7 to -1.0 Bar, see "Jacket Filling"
and "Water Treatment" in this manual.

d. Turn on the main power switch on the control face, controller will show
SET TnnP in the display.
e. Press the MANUAL button and turn the temperature knob to the desired
setting using the display (if a temperature is not selected after the MANUAL
button is pressed, the kettle will default to a heat setting of 5.0). The
heating indicator light indicates that the kettle is heating, and cycling of
the on and off indicates that the kettle is being held at the set temperature.
Once in each cycle the contactors in the support housing will make a
clicking sound. This is normal.

USE OF COMMON ACCESSORIES
1. Lift-Off or Counterbalanced Cover:
a. As with stock pot cooking, an optional cover can speed up the heating of
water and food products. It helps retain heat and reduces the heat and
humidity in the kitchen. A cover can reduce some product cook times
and help maintain the temperature, color and texture of products held or
simmered for longer periods.
b. Be sure the handle is secure on the lift-off cover before using. ALWAYS use
the handle to place or remove cover from the kettle. Wear protective oven
mitts and apron.
c. When putting the cover on the kettle, position it on top of kettle rim, with
its flat edge facing the pouring lip.
d. When removing cover:
1) Firmly grasp plastic handle.
2) Lift rear edge (farthest from operator) 1-2" (3-5 cm) to allow any steam
and water vapor to escape the cooking vessel. Wait 2-3 seconds.
3) Tilt cover to 45-60° angle and allow any hot condensate or product to
roll off cover back into kettle.
4) Remove cover, ensuring that any remaining hot condensate or product
does not drip on operator, floor or work surfaces.
5) Place cover on safe, flat, sanitary, out-of-the-way surface, or return to
kettle rim.
2. Basket Insert
An optional kettle basket insert can assist in cooking water-boiled products
including eggs, potatoes, vegetables, shell fish, pasta and rice. The nylon mesh
liner must be used when cooking product smaller than the mesh size of the
basket, which is approximately 1/4" (6 mm). This includes rice and small pasta
shapes. Tips for use:
a. Allow for the water displacement of the basket and product to be cooked.
This may mean only filling the kettle half full of water. Test the basket
and product displacement with the kettle OFF, and with cold water in the
kettle.
b. Load baskets on a level, stable work surface.
c. Lift loaded baskets with both hands. Get help from another person if the
basket is too heavy for safe handling.
d. Slowly lower product into kettle.
e. When removing baskets with cooked product, lift straight up, ensuring
basket bottoms clear the kettle rim and pouring lip. Wear protective oven
mitts and protective apron.
f. Allow hot water to fully drain from product before moving basket away
from the kettle. Do not rest baskets on kettle rim or pouring lip. If baskets
are too heavy for individual to lift and safely move, get help. Remove
product immediately from basket into another container, being sure to
avoid contact with hot product and hot basket or...
g. Place baskets with food on a stable, flat surface, inside a solid steamer or
bake pan,to catch any remaining hot water draining from product.
