1.0 INSTALLATION INSTRUCTIONS

Immediately after unpacking, check for possible shipping damage. If the kettle is found to be damaged, save the packaging materials and contact the carrier within 15 days of delivery.

1.The kettle must be installed in accordance with:

2.State and/or local codes.

3.In the USA, the National Electrical Code, ANSI/NFPA-70 (latest edition). In Canada, the Canadian Electrical Code, Part 1, CSA Standard C22.1 (latest edition).

4.Position appliance on counter allowing sufficient rear clearance from wall to tilt freely and completely without obstruction.

5.Mark four corner locations of appliance base.

6.Remove appliance from counter and locate position of 4 holes as per Figure 1. Drill four 7/16" diameter holes.

7.Use 5/16-18 Hex Cap Screws with suitable flat washers to bolt down. Screw length must be 1-1/4 long plus counter top thickness.

8.Apply a continuous bead of Silastic or other equivalent sealant along the complete perimeter edge of the appliance base.

9.Wipe off excess sealant.

10.A Control Box with power supply equivalent to Electrical Rating of appliance should be located conveniently nearby.

1.0 INSTALLATION INSTRUCTIONS (Continued)

WARNING: Disconnect electrical power supply and place a tag at the disconnect switch to indicate you are on the circuit.

1.A waterproof electrical connection for power supply to console housing must be provided.

2.Ground appliance to terminal provided inside console housing.

3.Turn power ON and check for proper operation.

2.0 INTRODUCTION

DESCRIPTION

Models KTG-6E (6 gallon capacity) and KTG-10E (10 gallon capacity) and KTG-12E (12 gallon capacity) electrically powered, self-contained, countertop, tilting kettles. Each model has a jacket of double-wall construction forming a sealed reservoir around the lower twothirds of the kettle. The reservoir is charged with distilled water and anti-freeze solution. Kettles are equipped with a removable electric heating element and controls, including a low water cutoff device for protection of the heating element. All models are of identical construction, except for kettle size and element heating capacity.

BASIC FUNCTION

Self-contained kettles operate by generating steam in the kettle reservoir. The sequence of operation is as follows:

1.Operator turns the power switch to the ON position and sets the temperature control dial to the desired setting from 1 to 10.

2.Control circuit is normally completed to the temperature controller if the following conditions exist:

A.Water level in the kettle reservoir is adequate to prevent circuit interruption by the low water cut off device. An activated cutoff is indicated by the amber low water light turning on, and the heating element shut off.

B.Kettle is in vertical position with circuit completed through the tilt interlock switch.

3.Thermostat control contacts close to energize contactor coils.

4.Power is supplied to the elements through closed power contactors.

5.As the temperature of water rises in the kettle reservoir, increase in steam pressure is indicated on the pressure gauge.

6.When the temperature of steam in the reservoir reaches the setting of the temperature control dial, the temperature controller opens to break the contacts and shuts off the heating element. The heating elements will cycle on and off as required to maintain temperature setting.
