Operational and Maintenance Safety
WARNING
INSTALLATION OF THE UNIT MUST BE DONE BY PERSONNEL QUALIFIED TO WORK WITH
ELECTRICITY AND PLUMBING IN ACCORDANCE WITH ALL APPLICABLE CODES.
BEFORE REPLACING ANY PARTS, DISCONNECT THE UNIT FROM THE ELECTRIC POWER SUPPLY.
TO PREVENT SHOCKS, ALL APPLIANCES WHETHER GAS OR ELECTRIC, MUST BE EARTHED.
CAUTION
BE SURE ALL OPERATORS READ, UNDERSTAND, AND FOLLOW THE OPERATING INSTRUCTIONS,
CAUTIONS AND SAFETY INSTRUCTIONS CONTAINED IN THIS MANUAL.
Operation
1. Initial Operational Readiness Check
After the TDB/7 Kettle has been installed according
to service and installation instructions, perform initial
start-up as a test, to ensure that the unit is operating
correctly.
a. Remove all literature and packing material from
the interior and exterior of the unit.
b. Make sure electricity supply is switched on.
c. Ensure that the kettle is filled with water.
d. Check the water level in the jacket. The level
should be between the lines on the gauge glass.
If the level is low, the jacket water level will be
required to be topped up. (This will require a
service call).
e. Check the pressure gauge. If the gauge does not
show sufficient vacuum (20 to 30 below zero)
then the jacket will require venting. (This will
require a service call).
f. Switch the On/Off switch to the "On" position.
The "power on" neon will illuminate.
g. Turn the thermostat dial to the required setting.
The "heat" neon will illuminate.

operating thermostat dial from “OFF” to a desired
setting, the thermostat switch closes. This lights up
the heating indicator light and causes the contactors
to close, allowing power to flow to heating elements.
