Introduction
DESCRIPTION
Floor model kettles are self-contained, self-generating
steam jacketed vessels for cooking large volumes of liq-
uid and semi-liquid food products. All models include a
hemispheric shape based on double-wall construction
forming a steam jacket reservoir around the lower two-
thirds of the kettle. The reservoir is charged with distilled
water, rust inhibitor and antifreeze solution and is vacu-
um-sealed. Kettles are equipped with electric heating ele-
ments and controls including a low water cut-o󰀨 device for
protection of heating elements.
Two model series di󰀨er in that KLT-__E units are leg -
mounted tilting kettles while KPS-__E units are pedestal
mounted stationery kettles. Optional leg mounting of the
pedestal models is designated by the model number se-
ries KLS-__E. The missing gures of the model numbers
are the two digits representing the kettle capacity, ie, KLT-
20E for a 20 gallon tilting kettle.
BASIC FUNCTIONING
Self-contained kettles operate by generating steam in the
kettle reservoir; the sequence of functioning, which oc-
curs during operation, is as follows:
1. Operator places the power switch in the ON position
and sets the thermostat knob at the required setting
from ‘’1’’ to”10” – 165°F (74°C) to 285°F (140°C ) -
jacket temperature.
2. Control circuit is normally completed to the thermo-
stat control if two standard conditions exist:
a. Water level in kettle jacket is adequate to’ prevent
circuit interruption by the low water cut-o󰀨 device.
An activated cut-o󰀨 is evidenced by the
Low Water light turning on and heating element
cut o󰀨.
b. Kettle is in vertical position with circuit complet-
ed through the tilt interlock switch (KLT-E series
only).
3. Thermostatic control contacts close to energize heat-
er contactor coils and turn temperature Indicator light
on.
4. Power is applied to heaters through closed contactor
power contacts.
5. As temperature of water rises in kettle reservoir, the
steam pressure increase is indicated by the vacuum
pressure gauge.
NOTE: Gauge normally reads 22-30 IN. Hg (74-100
k/Pa) (below 0 PSI, prior to heaters turning
on. Air is eliminated from the system when
jacket is lled (with the kettle reservoir at a
pressure above 0 PSI) by opening the bleed
vent one full turn for 10 seconds and closing.
6. When temperature of steam in the reservoir reaches
the temperature coinciding with the thermostat set-
ting, the thermostat switch opens to break the circuit
to the contractor coils and shuts o󰀨 the elements. Any
number of on and o󰀨 cycles of the control thermo-
stat, contactors and elements will occur as required
to maintain thermostat setting,
SERVICE
Required service, both preventive and corrective. is ex-
plained in the maintenance section. Should repairs be
required, a network of authorized agencies is available
to assist with prompt service. A current Directory of Au-
thorized Service Agencies may be found by visting our
website, www.blodgett.com.
The model and serial numbers must be referenced when
corresponding with Blodgett. The data plate containing
the serial number pertaining to the equipment is located
on rear of kettle.

INSTALLATION
Installation Instructions
1. Select a location to provide drainage directly below
the tangent draw-o󰀨. Allow su󰀩cient rear clearance
from wall for kettle cover to lift upright freely and com-
pletely without obstructions.
2. Mark hole locations through anged adjustable feet
on KLT-__E models. Remove kettle.
3. Drill holes on marked hole locations, and insert ex-
pansion shields to accommodate 5/16” size lag bolts.
4. Reposition kettle. On KLS-__E models level by mak-
ing necessary adjustments on anged feet.
5. Bolt down kettle and seal with Silastic or other equiv-
alent sealing compound. Sealant must be applied not
only to bolt heads but also around anges or pedestal
base making contact with oor surface to fulll NSF
requirements. Wipe o󰀨 excess sealant immediately.
6. A control box with power supply equivalent to electri-
cal
7. Rating of kettle should be located conveniently near-
by.
8. A waterproof electrical connection for power supply to
rear of control housing must be provided.
9. Ground kettle to terminal provided inside control
housing.
10. Turn power ON and check for proper operation.

7OPERATION
Operating & Cleaning Instructions
OPERATION
1. Check kettle pressure gauge that reading indicates
20-25 vacuum for a cold kettle. If vacuum is insuf-
cient, air venting instructions must be followed. If
equipped with draw o󰀨 valve ensure valve is closed.
2. Place kettle power switch in ON position.
3. Preheat kettle by turning thermostat knob to ‘8’ and
wait until temperature pilot light goes o󰀨.
NOTE: Food products with milk or egg base should
be placed into cold kettle and then the cook-
ing operation begun. Avoid sudden contact
of these food products to hot kettle bowl sur-
face since caking/adhering will occur.
4. Place food product into kettle bowl. Close kettle cover.
5. Adjust thermostat knob to temperature cooking mode.
Setting of 6-7 will provide simmer and 8-10 low to roll-
ing boil.
6. Turn both kettle power switch and thermostat knob
OFF when cooking has been completed.
7. Remove food product by ladling out of kettle bowl or
by opening draw-o󰀨 valve and pouring into a suitable
container.
WARNING
DRAW OFF VALVE HAS A VUCANIZED RUB-
BER COATED STEAM FOR BETTER SEALING.
DO NOT OVERTIGHTEN. THIS MAY CAUSE
THE RUBBER TO PULL AWAY FROM STEAM
AND PERMANENTLY DAMAGE IT.
CLEANING
Your kettle should be cleaned immediately after each use
to prevent food residue from drying and adhering too ket-
tle bowl and valve surfaces.
1. Turn power supply OFF to kettle
2. Rinse inside of kettle thoroughly. Drain kettle by tilt-
ing or if equipped wit-h drain valve, open valve and
remove all food particles. Close drain valve.
3. Using nylon brush. clean kettle with a mild detergent
and warm water rinse. Never use steel wool or scour-
ing powder as they will scratch stainless steel. Food
adhering excessively to bowl surface may be loos-
ened by allowing water to soak in a bowl at a low
temperature setting.
4. Open the draw-o󰀨 to allow soap and water solution
to drain.
5. By hand, turn large hex nut on draw-o󰀨 valve counter
clockwise until completely disengaged from thread.
Grasp valve knob and pullout valve steam and disc
slowly.
6. Avoid contact of valve disc with hard surfaces since
damage to disc may occur and result in valve leak-
age. Wash the valve stem, disc and handles. Insert
nylon brush with detergent into interior of valve body
and tangent draw-o󰀨 tube and brush vigorously.
7. Replace valve stem assembly and engage hex nut
fully by hand. Flush kettle with clean warm water and
leave valve open when kettle is not in use.
8. Wipe down exterior of kettle with clean damp cloth.
WARNING
It is NOT RECOMMENDED to use cleaning
agents that are corrosive.
Use of cleaning agents that contain chloride,
acids or salts are corrosive and may cause
pitting and corrosion when used over a period
of time; this will reduce the life of the appli-
ance.
Should pitting or corrosion occur this is not
covered by warranty.
Follow the recommended cleaning instruc-
tions Use detergent, warm water and rinse
thoroughly.
NEVER SPRAY WATER INTO ELECTRIC CON-
TROLS.
