OPERATOR SELF HELP
Before calling for service, review this list. It may save
you both time and expense. This list includes
common occurrences that are not the result of
defective workmanship or materials in this appliance.
NOTE: For a fryer with a Central Filter or Safe & Easy®
Filter always check the rear drain operating handle
before attempting to use the fryer. A safety switch
prevents the fryer from operating if the handle is not
pushed in completely and latched. (See figure 3-2)

PREVENTIVE MAINTENANCE
Preventive maintenance should be done in daily,
weekly, monthly and yearly intervals as necessary.
Following preventive maintenance procedures will help
keep your fryer working efficiently. Proper care and
servicing will lead to years of quality performance.
PREVENTIVE MAINTENANCE CHART

HI-LIMIT CHECK BI-MONTHLY

Place an accurate thermometer in the oil. If the Hi-Limit
Control doesn’t shut off the fryer between 425°F and
450°F, have it replaced.

THERMOSTAT CALIBRATION

You will need:
One screwdriver with 1/8" wide flat blade
One accurate fryer thermometer
1. Set thermostat to desired frying temperature.
2. Allow fryer to cycle three times.
3. Place an accurate thermometer in the oil.
Thermostat calibration
NOTE: Locate thermometer in same position for every
calibration. Left front corner of fryer vessel at the High
Limit Bulb is recommended.
4. If temperature of fryer is found to be more or less
than 15°F off, remove the thermostat knob. There
are (4) screws holding the dial plate in place.
Loosen the screws and reset the dial plate to
match the thermometer reading.
BEFORE REPLACING, TEST THERMOSTATS
These operational problems can easily be corrected
by thermostat bulb positioning.
Keating’s patented thermostat application is
accurate within 2°F of the dial setting between
250°F – 350°F. This accuracy is attained only if the
thermostat bulb is placed properly against the heat
transfer tube. To quickly and accurately test for
proper bulb placement, a single thickness of
writing paper should be pulled through between
the tube and the bulb with medium resistance.*
1. *For gas fryers 14":
The end of thermostat bulb should touch the
burner tube.
2. For gas fryers 10×11, 18" & larger:
If the bulb is too loose, the paper will slip through
with little or no resistance. A fryer with a thermostat
bulb that is too loose will overshoot.
Overshoot: The thermostat takes a long time to
cycle and then misses its preset temperature by
20°F - 40°F yielding a poor quality product.
If the bulb is too tight, the paper will either not pull
through or it will tear. A fryer with a thermostat bulb
that is too tight will short cycle.
Short Cycle: The thermostat will cycle rapidly while
the fryer is in the idle mode; the temperature will be
erratic.
