EXTREMELY SLOW COOKING TIME
1. If the cooking time is abnormally slow, then the difficulty may be due to air being
present in the kettle jacket. To remove air, follow AIR VENTING INSTRUCTIONS.
2. If the kettle will not reach and maintain Pressure Gauge zone in the green area on the gauge
when cold, a slow leak may have developed in the jacket. Check all fitting connections to
jacket including the heating element gasket. Tighten or replace if necessary.
3. Slow cooking time may also be due to a burnt out heating element. Test elements
and if defective, replace complete element assembly.
KETTLE WILL NOT OPERATE WHEN TURNED ON
1. Check that power supply is available to kettle.
2. Kettle will not operate if water level is inadequate in jacket. Follow LOW WATER
LEVEL instructions.
3. If water level is sufficient and kettle refuses to operate, then check that Tilt Interlock
Switch in Console is fully engaged when kettle is in its normally upright position. Adjust
Retaining Tilt Collar if necessary to assure complete contact with switch and if kettle still
does not operate, then check for defective switch and/or loose wiring connections.
4. When Thermostat Knob is dialed and TEMPERATURE indicator light does not come on,
then it may be due to either a defective Thermostat or loose wiring connections(s).
5. Check that the Contactor(s) are being energized and power is being made available to
the heating elements when thermostat is dialed. Replace defective Contactor(s).
AIR VENTING INSTRUCTIONS
Check vacuum/pressure gauge when the kettle is cold. Gauge should be in the green
vacuum zone, indicating a vacuum between 25-30 In. Hg (630 - 730 mm Hg). If not, air must
be vented (removed) for proper heating. Use the following procedures to vent air.
1.
Place power switch ON with kettle empty.
2.
Set temperature control thermostat to ‘10'. Heat kettle until indicator light goes off.
