F-PEF & F-LEF STATIONARY ELECTRIC KETTLES
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 fine 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 ket-
tle 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.
