MAINTENANCE
WARRANTY REPAIRS
Keating’s warranty begins with the date of installation
(or ship date if we are not notified of an installation
date).
In the event that your fryer, under warranty, needs
repairs other than routine maintenance or cleaning,
you are required to contact Keating of Chicago
(at 1-800-KEATING) before calling a local service
company. Failure to do so may void your warranty.
PREVENTIVE MAINTENANCE
Preventive maintenance should be done in daily, week-
ly, 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.
A. Oil Breakdown
As part of a “Preventive Maintenance Program”, the oil
in your fryer needs to be filtered regularly to avoid
breakdown. The initial investment in the frying system
is less than the total overall costs of oil during the life of
the fryer, and with regular filtering, you can realize sub-
stantial savings in oil costs, as well as maintenance
charges.
B. 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 at the tip
of the thermostat bulb.

NOTE: Locate thermometer in same position for every
calibration.
4. If calibration of fryer is found to be less than 25°F
off, simply loosen the four retaining screws holding
the dial plate in place. Reset the dial plate to match
the thermometer reading. If the fryer is found to be
more than 25°F off, a qualified service company
must be contacted to have the fryer properly
calibrated.
Do NOT adjust set screw on thermostat.
C. Thermostat Bulb Positioning
BEFORE REPLACING, TEST THERMOSTATS:
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 burn-
er tube.
2. For gas fryers 18" & up:
If the bulb is too loose, the paper will slip through
with little or no resistance. A fryer with a thermo-
stat 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.
