Equipment Description
The KTT-DS are tilting, table-top kettles with direct steam-heated jackets. The onepiece stainless steel body on each includes a butterfly shaped pouring lip. The kettles
have a 180 emery grit interior finish and a bright semi-deluxe exterior finish.
Every unit requires a remote steam source. The steam supply is controlled by an inlet
valve, and enters the jacket through one support and rotary joint. Condensate leaves
the jacket through the other rotary joint and support. Standard units are ASME shop
inspected, stamped, and registered with the National Board. These kettles operate
efficiently at pressures above five PSI. A safety valve, strainer, steam trap, and check
valve are all required for installation, and may be ordered as optional equipment.
Optional features and equipment include:
• Higher maximum pressure • Bracket inserts
• Lift-off covers • Kettle brush kit
• Open leg mounting table mounting • Steam trap assembly
The 5/6DS-KTT kettle has a jacket rated for working pressures up to 55 PSI. The
kettle body incorporates a triple reinforced rim. Two tubular steel supports support the
swivel on which the kettle tilts. A leg projects from the bottom of the kettle.

Installation
WARNING
THIS UNIT MUST BE INSTALLED BY
PERSONNEL QUALIFIED TO WORK WITH
PLUMBING. IMPROPER INSTALLATION CAN
CAUSE INJURY TO PERSONNEL AND/OR
DAMAGE TO EQUIPMENT.
1. Installation under a ventilation hood is recommended. Consult local codes.
2. Install and anchor the kettle on a level and rigid surface. Recommended
mounting surface is 16 gauge (.060” thick) top with a lower reinforcement
of C4 structural channel. NOTE: Failure to install the kettle per above
recommendation may cause the steam piping to flex and leak, reduce seal life
and will void warranty.
3. If the steam supply pressure is greater than the maximum working pressure
stamped on the nameplate, you must install a pressure reducing valve in the
steam supply line near the kettle.
4. Connect the steam supply line to the steam inlet fitting. Include a steam control
valve and an appropriate safety valve. To obtain the full heating capability of
the kettle, the steam supply line must be as large as the steam inlet fitting.
5. The safety valve is preset to relieve jacket pressure that exceeds its rated limit.
Do not try to adjust the valve setting, and do not allow the valve outlet or lever
to be blocked.
6. Connect the kettle condensate return line to the boiler return line, or to a drain.
A suitable steam trap, strainer, and check valve must be installed. (See piping
diagram, below).
7. Any mechanical change must be approved by the Service Department.
Standing Piping
The inlet valve may be located anywhere on the cabinet top or face but not through
the face casting. The illustrated sleeve is designed to simplify valve installation by
allowing the valve to shift off center by 1/4”, if necessary. This should be enough to
allow for thread take-up and misalignment.
*Accessories available as options. Piping is to be supplied by the installer.

1) WEAR PROTECTIVE OVEN MITT
AND PROTECTIVE APRON.
2) USE CONTAINER DEEP ENOUGH
TO CONTAIN AND MINIMIZE
PRODUCT SPLASHING.
3) PLACE CONTAINER ON STABLE,
FLAT SURFACE, AS CLOSE TO KETTLE
AS POSSIBLE.
4) STAND TO LEFT OR RIGHT SIDE OF
KETTLE (DEPENDING ON TILTING
HANDLE PLACEMENT) WHILE POURING.

CONTAINER AND ITS CONTENTS.
To heat the kettle, open the steam inlet valve. Adjusting the valve allows you to
control the heating rate. Opening the valve more allows steam to flow into the jacket
faster, and heats the product faster.
The kettle operates efficiently at pressures from five PSI to the maximum working
pressure for which the kettle was designed. The maximum pressure is stamped on
the kettle nameplate.
1. Tilting
To transfer product or empty the kettle: the kettle is designed and manufac-
tured to be tilted in a controlled manner. Grasp the insulated plastic ball firmly.
Maintain a firm grip on handle when tilting, while keeping the kettle body in a
tilted position and then SLOWLY returning the kettle body to an upright position.
2. Accessories
A. Cover
As with stock pot cooking, an optional lift-off cover can speed up the
heating of water and food products. A cover helps retain heat in the
cooking vessel and reduces the amount of heat and humidity released
into the kitchen. Use of a cover can reduce some product cook times and
help maintain the temperature, color and texture of products being held
or simmered for extended periods.
Make sure plastic ball handle is secure on the lift off cover before using.
ALWAYS use the plastic handle to place or remove the cover from the
kettle. Wear protective oven mitts and a protective apron.
When putting the cover on the kettle, position it on top of kettle rim, with
its flat edge facing the pouring lip.
When removing cover:
a) Firmly grasp the plastic handle
b) 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.
c) Tilt cover to 45-60° angle and allow any hot condensate or prod-
uct to roll off cover back into kettle.
d) Remove the cover, ensuring that any remaining hot condensate or
product does not drip on operator, floor or work surfaces.
WARNING
AVOID EXPOSURE TO ESCAPING STEAM,
WHICH CAN CAUSE SEVERE BURNS.
CAUTION
DO NOT TILT KETTLE BODY WITH COVER
IN PLACE. COVER MAY SLIDE OFF,
CAUSING INJURY TO OPERATOR.

B. Basket Insert
An optional kettle basket insert (10 Quart and larger) can assist in cook-
ing 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.
Allow for the water displacement of 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.
a) Load basket on a level, stable work surface.
b) Lift the loaded basket with both hands. Get help from another
person if the basket is too heavy for safe handling.
c) Slowly lower product into kettle.
d) When removing basket with cooked product, lift the basket
straight up, ensuring that the bottom of the basket clears the rim
and pouring lip of the kettle. Wear protective oven mitts and a
protective apron.
e) Allow hot water to fully drain from product before moving the
basket away from the kettle. Do not rest the kettle basket on the
kettle rim or pouring lip. If the basket is too heavy for one individual to lift and safely move, get help from another person. Remove
product immediately from the basket into another container, being
sure to avoid contact with hot product and hot basket or. . .
f) Place basket with food on stable, flat surface, setting it inside
a solid steamer or bake pan, to catch any remaining hot water
which might drain from product.
OM-KTT-DS 9
Page 12
Sequence of Operation
The following “action-reaction” outline is provided to help the user understand the
function of the equipment.
When the steam inlet valve is opened, steam flows into the jacket at a pressure
determined by the boiler system or by the pressure reducing valve that serves the
kettle.
In the jacket, steam transfers heat to the kettle as it condenses into water. The steam
trap allows condensate (water) to leave the jacket, while it holds steam in. When the
steam is shut off, condensation produces a vacuum in the jacket, but the check valve
in the condensate return line keeps water from flowing back into the jacket.
