On most TDB/7 units the jacket water level is
shown in a sight glass, right on the kettle.
Operation
The operator controls kettle heating withthe
thermostat dial. The dial turns heating element
electric power on or off and sets the operating
temperature of the kettle.
A. To Start Kettle
1. EVERYDAY make sure thatthe jacket
water level is above the mid-point of the
round sight glass (new models) or
between the marks onthe gauge glass
(old models). If the level is too low, see
“Jacket Filling and Water Treatment” on
page 10 of this manual.
2. Check the pressure gauge. If the gauge
does not show20 to 30 inches of vacuum
(that is, a reading of 20 to 30 below0), see
“Jacket Vacuum” on page 10 of this manual.
3. Turnon the electrical power to the unit.
4. Turnthe thermostat dial to the desired
setting. The heating indicator light indicates
that the kettle is heating, and cycling of the
light on and off indicates that the kettle is
being held at the set temperature. Once in
each cycle the contactors inthe support
housing will make a clicking sound. This is
normal.
