TROUBLESHOOTING

SAFETY VALVE MAINTENANCE AND TESTING

CAUTION

Under normal operating conditions a “try lever
test” should be performed every two months.
Under severe service conditions, or if corro­sion and/or deposits are noticed within the
valve body, testing must be performed more
often. A “try lever test” should also be per­formed at the end of any non-service period.

CAUTION

Hot, high pressure uid may be discharged

from body drain and vent during “try lever”
test. Care must be taken to avoid any bodily
contact.

CAUTION

High sound levels may be experienced during
“try lever” test. Wear proper safety equip­ment and exercise extreme care! Test at, or
near, half of the operating pressure by holding
the test lever fully open for at least two sec-

onds to ush the valve seat free of sediment

and debris. Then release lever and permit the
valve to snap shut.

If lift lever does not activate, or there is no
evidence of discharge, turn off equipment im­mediately and contact a licensed contractor or

qualied service personnel.

LOW WATER LEVEL

Proper water level must be maintained within the jacket
for the kettle to operate. Depletion of water may occur
from excessive opening of or leakage through the safety
relief valve.

If water is below required operating level, either initially
at start-up or during use, the kettle will automatically shut
off, and the LOW WATER signal light will come on.

In order for the kettle to operate, the following procedure
must be followed:

The kettle must be cool before proceeding with the fol­lowing steps.

1. Trip the safety relief valve lever to relieve all pressure
from the kettle jacket.

2. At exterior rear of kettle jacket remove nut from Air
Vent.

3. Insert funnel into Air Vent opening and slowly add the
indicated amount of distilled water for:

4. Replace Air Vent nut.

5. Follow Air Venting Instructions below.

6. Continue normal Operating Procedure of kettle.

EXTREMELY SLOW COOKING TIME

1. If the cooking time is abnormally slow, then the dif-

culty 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 tting 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 sufcient 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 connection(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).

TROUBLESHOOTING

DRAW-OFF VALVE LEAKS

If leak occurs through the valve stem, replace the “O” ring.
If the leak is caused by faulty sealing between the stem
disc and valve seat, this can be corrected by cleaning off

dried on food residue with an extremely ne emery cloth.

If the vulcanized rubber stem piece has been damaged,
it must be replaced.

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.

3. Using a 7/16" wrench, open bleed vent one full turn
for 10 seconds and then close. (Located on back of
kettle, before pressure relief valve.)

CAUTION

SCALD HAZARD. Live steam will escape the
bleed nut when opened. Stay clear of live
steam when performing this operation.

4. Cool kettle. Check for proper vacuum in green area of
gauge. If vacuum was not established, repeat steps
1 - 4.
