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.

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 correct- ed by thermostat bulb positioning.
Keating’s patented thermostat application is accu- rate within 2°F of the dial setting between 250°F – 350°F. This accuracy is attained only if the thermo- stat bulb is placed properly against the heat trans- fer 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 10x11, 18 & up:
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.
