2.0 INSTALLATION INSTRUCTIONS
WARNING: Electrical and grounding connections must comply with
applicable portions of the National Electrical Codes.
WARNING: Plumbing connections must comply with applicable health,
safety and plumbing codes.
1. Select a location to provide drainage directly below the draw-off valve. Allow
sufficient rear clearance from the wall for the kettle cover to lift upright freely without
obstructions. Allow for clearance to side service panels.
2. Level the unit. Then mark anchoring hole locations through flanged adjustable feet.
3. With hole locations marked, drill holes and insert expansion plugs to accommodate
5/16" size lag bolts.
4. Reposition the kettle. Check the level again.
5. Bolt the kettle down and seal with a high grade sealing compound. Sealant must be
applied not only to bolt heads but around the flanges and must be making contact
with floor surface to meet N.S.F. requirements. Wipe off excess sealant
immediately.
6. Connect the steam line to the kettle (3/4" i.p.s., 5 psi minimum to 30 psi maximum, or
45 psi with optional high pressure operation).
7. If the incoming steam pressure is greater than the kettle maximum operating
pressure, then a pressure reducing valve (supplied by others) must be installed in
the line.
8. Connect hot and cold water supply to the faucet.

6
INSTALLATION INSTRUCTIONS (Continued)
9. A control box with a power supply equivalent to electrical rating of the unit should be
located nearby. A waterproof electrical connection for the power supply to the unit
must be provided.
10. The relief valve on the kettle must not be adjusted or closed off as it is set to relieve
excess pressure in the kettle.
11. If large amounts of water accumulate in the steam line, it will be necessary to install
one or more ball float traps (supplied by others) in the line to eliminate the water.
12. A steam line pressure gauge (supplied by others) is also recommended to determine
the actual amount of steam coming to the kettle.
13. Turn unit on when electrically connected, then check for proper operation.

3.0 INTRODUCTION
DESCRIPTION
The Blodgett KCH-DS kettles are direct steam tilting models mounted in a modular
cabinet base. It has a hydraulic pump and cylinder to tilt the kettle to any angle between
zero and ninety degrees for complete emptying of food products. Includes a pan carrier
that holds a 12" x 20" pan. (Pan not supplied.)
The KCH-DS are direct steam operated pressure vessels with a double wall stainless
steel construction forming a steam chamber (jacket) around the lower two thirds of the
kettle. These kettles are furnished with a steam control valve and a hot and cold water fill
faucet mounted on the stainless steel counter top. Every kettle has a pressure relief
valve. Access to the inner cabinet area for installation or service is through the
removable side panels or the doors on the front of the unit.
The kettle bowl is the container for the food product which ideally should be a liquid or
semi-liquid for complete contact with the bowl surface to fully absorb the heat
transmitted through the surface from the steam in the kettle jacket.
These kettles are intended to be permanently floor mounted with adjustable flanged feet.

4.0 BASIC FUNCTIONING
1. CAPACITIES
All model names contain either a 30, 40 or 60 to indicate the capacity of that kettle in
gallons. For example, model KCH-40DS indicates a tilting two thirds jacketed steam
kettle mounted in a cabinet base, with a capacity of 40 gallons.
CONTROLS
The electric controls are in the upper right area of the kettle front. One control is an
ON-OFF switch for the tilting mechanism. The second control, in the up position tilts
the kettle forward to full tilt. In the down position the kettle is lowered to full down.
Stopping the up or down control will hold the kettle at any position the kettle is
stopped.
PAN CARRIER
The KCH-DS is equipped with a pan carrier. The pan support is made of stainless steel
and is removable, without tools, for cleaning. It holds one 12" x 20" pan and will locate
the pan in a horizontal position not more than 2" from the kettle lip throughout the tilting
operation.
SWING DRAIN
Each kettle has a swing drain to use with the draw-off valve. It is removable, without
tools, and has a removable strainer.
HYDRAULIC SYSTEM
The hydraulic system has been adjusted and tested at the factory and no further
adjustment should be needed. If the unit fails to operate properly, all service work must
be performed by a qualified service agent.

5.0 OPERATING INSTRUCTIONS
WARNING: Do not tilt kettle with lid down.
WARNING: The kettle is hot. Use care when operating and servicing the kettle.
1. Turn the power switch on only during tilt cycles. Running the hydraulic power unit
continuously may overheat or damage the system.
2. Push the toggle switch to the up position. Check that the kettle begins to rise. Allow
the kettle to travel to its full up position then push the toggle switch to the down
position and the kettle will return to the original position. The kettle will stop and hold
its position at any point along the travel path if the toggle switch is released.
3. Check that the draw-off valve is closed.
4. Fill the kettle with product to the desired level.
5. Slowly turn the steam control valve to the full open position (counterclockwise). The
kettle will begin to heat
6. Regulate the steam control valve depending on the type of food being prepared.
7. When the food is cooked, turn off the steam, remove the food by tilting. Clean the
kettle immediately to prevent residue from drying on the kettle bowl.
NOTE: Food products with milk or egg base should be placed into a cold kettle before the
cooking operation begins. Avoid sudden contact of these food products in a hot kettle, the
food will stick to the surface.

6.0 MAINTENANCE
KETTLE
No preventive maintenance is required other than adhering to the Cleaning Procedure
instructions.
HYDRAULIC SYSTEM
SERVICE
Set up regular schedule for checking the oil temperature, hydraulic hoses and keeping
the equipment clean. A thick layer of dirt acts as insulation and prevents the hydraulic
system from getting rid of heat.
The hydraulic system has been adjusted and tested at the factory and no further
adjustment should be needed. If the unit fails to operate properly, all service work must
be performed by a qualified service agent.
1. Hot oil in the Hydraulic System is one of the primary causes of poor operation.
When the tilt system is not in use turn MOTOR switch off.
2. Inspect hydraulic hoses for wear and aging.
3. Check that fluid levels are kept full.
4. To replace oil, fill through filler breather.
5. Use proper oil as specified by factory. TYPE: AWH32 or equivalent.
6. Check the cleanliness of the oil strainer inside the reservoir once per year. This item
can be washed in clean Varsol.
7. Change the breather filter once per year.
8. Change the oil once every two years.
