Model KTT

Model KTC

Equipment Description

The KTT and KTC are table top, tilting, steam jacketed kettles with a thermostatically controlled, self-contained, electrically-heated steam supply and appropriate controls, mounted on a sturdy base. Models are available in 5, 6, 10 and 12-gallon capacity.

The body of the kettle is constructed of stainless steel, welded into one solid piece. The kettle is furnished with a reinforced rim and a butterﬂy shaped pouring lip. It has a steam jacket rated for a design pressure of 50 PSIG. Kettle ﬁnish is 180 emery grit on the inside and bright semi-deluxe on the outside. A tilt handle on the KTT kettle and a hand wheel crank on the KTC kettle allows the operator to manually tilt the kettle body in a controlled manner. Pouring height accepts pans up to four inches high on a table top.

A built-in steam generator, sized for the kettle capacity and heated by electricity, delivers steam into the jacket. “Airless” operation of the steam jacket permits uniform, efﬁcient heating at temperatures as low as 150°F and as high as 295°F. In addition to the adjustable thermostat for operating control, the unit has a tilt cut-off switch, low water cut-off, pressure relief valve, and high-limit pressure switch as safety features. A heating indicator light, pressure gauge, and sight glass are provided for monitoring kettle operation.

A single electrical connection is required for installation. The unit may be ordered for use with 208/240 or 480 volt power. All 208/240 volt kettles are wired for 208 volt, three-phase operation. For 240 volt, three-phase OR single-phase conversion, see the wiring diagrams and installation instructions in this manual.

Inspection & Unpacking

CAUTION

SHIPPING STRAPS ARE UNDER TENSION

AND CAN SNAP BACK WHEN CUT. TAKE

CARE TO AVOID PERSONAL INJURY OR

DAMAGE TO THE UNIT BY STAPLES LEFT

IN THE WALLS OF THE CARTON.

CAUTION THIS UNIT WEIGHS 140 TO 163 LBS (64 TO 74 KG). INSTALLER SHOULD OBTAIN HELP

AS NEEDED TO LIFT THIS WEIGHT SAFELY.

The unit will arrive in a heavy shipping carton and will be bolted or banded to a skid. Immediately upon receipt, inspect the carton carefully for exterior damage.

Carefully cut any polyester straps around the carton and detach the sides of the box from the skid. Pull the carton up off the unit. Thoroughly inspect the unit for concealed damage. Report any shipping damage or incorrect shipments to the delivery agent.

Write down the model number, serial number, and installation date, and retain this information for future reference. Space for these entries is provided at the top of the Service Log at the back of this manual. Keep this manual on ﬁle and available for operators to use.

When installation is to begin, carefully cut any straps which hold the unit on the skid. Lift the unit straight up off the skid. Examine packing materials to be sure loose parts are not discarded with the materials.

For KTT units, attach the tilt handle (normally shipped inside the kettle) by carefully threading it into the socket on the trunnion support. Be careful to avoid cross-threading the ﬁne threads on the trunnion.

NOTE: After handle installation on the right

hand side, retain the hardware supplied with

the unit for left hand installation.

Installation

WARNING

INSTALLATION OF THE KETTLE MUST BE

DONE BY A CERTIFIED ELECTRICIAN OR

AUTHORIZED REPRESENTATIVE QUALIFIED

TO WORK WITH ELECTRICITY. IMPROPER

INSTALLATION CAN RESULT IN INJURY TO

PERSONNEL AN/OR DAMAGE

TO EQUIPMENT.

CAUTION

BEFORE ANY ELECTRICAL CONVERSION,

VERIFY THAT THE BRANCH CIRCUIT

WIRING IS ADEQUATE TO HANDLE ANY

INCREASE AMPERAGE REQUIREMENTS.

REFER TO THE ELECTRICAL

SPECIFICATIONS LISTED BELOW.

The KTT/KTC Kettle is provided with complete internal wiring and is ready for immediate connection. Wiring diagrams are provided in this manual and on the inside of the control housing service panel. Any mechanical or electrical changes must be approved by Blodgett’s Engineering Department.

The completed unit has been operated at the factory to test all controls and heater elements.

1. Set the kettle in place and level it. The base should be securely fastened to a table or work surface. Four 3/8”-16 N.C. threaded couplings are provided in the base of unit. Installation under a ventilation hood is recommended.

2. Once the unit is anchored to a mounting surface, apply a small bead of silicone caulk around the perimeter of the kettle base and seal the joint.

3. Provide electrical power as speciﬁed on the electrical information plate attached to the equipment. Observe local codes and/or The National Electrical Code in accordance with ANSI/NFPA 70 - (current edition).

4. Standard equipment is shipped ready for 208V, 3-phase or 480V, 3-phase operation. Refer to the wiring diagram located on the inside cover of the control box and the instructions below for conversion to single-phase operation. A jumper wire and “conversion” label are included with the unit. They can be found in a plastic bag attached to the trunnion assembly inside the control box.

a. For conversion from 208V, 3-phase to 208V or 240V 1-phase or

480V, 3-phase to 480V, 1-phase:

i. Verify that the branch circuit wiring is adequate for any

increased amperage requirements (see table on page 8).

ii. For 240V 1-phase only, enlarge electrical inlet opening for

1” conduit ﬁtting. Use a 1” sealtite conduit ﬁtting.

iii. Refer to wiring diagram for ﬁeld conversion.

iv. For 240V 1-phase only, pull lead from 208V tab on control

transformer and insert on 240V tab (See photo on page 8).

v. Complete “conversion label” (supplied in bag) and adhere it

to the control box near the UL dataplate.

b. For conversion from 208V, 3-phase to 240V, 3-phase:

i. Verify that the branch circuit wiring is adequate for any

increased amperage requirements (see table on page 8).

ii. Pull lead from 208V tab on control transformer and insert

on 240V tab. (See photo on page 8)

6 OM-KTT/KT C-E

iii. Complete “conversion label” (supplied in bag and adhere it

to the control box near the UL dataplate).

Installation

DANGER

ELECTRICALLY GROUND THE UNIT AT

THE TERMINAL PROVIDED. FAILURE TO

GROUND UNIT COULD RESULT IN

ELECTROCUTION AND DEATH.

Pull lead from 208V tab and insert on 240V tab.

c. For conversion from 480V, 3-phase to 460V, 3-phase:

i. Verify that the branch circuit wiring is adequate for any

increase amperage requirements (see table on page 8).

ii. Complete “conversion label” (supplied in bag and adhere it

to the control box near the UL dataplate).

5. Bring incoming electrical service through the conduit ﬁtting (for 240V 1-phase, a new one inch conduit ﬁtting is required) at the rear of the support housing, making a watertight connection with the incoming lines. A BX style connection is not recommended.

6. Conﬁrm that the jacket water level is at or just above mid point of sight glass (new models). If the level is low, follow the instructions under “Jacket Filling and Water Treatment” in the “Maintenance” section of the manual.

7. Ensure that the open end of the elbow on the outlet of the pressure relief valve is directed downward.
