Keating Of Chicago INSTANT RECOVERY GAS FRYER Service Manual - V Service Diagnosis
simply loosen three dial plate retaining screws,
rotate dial plate to match thermometer reading and
tighten screws. For calibration over a 15°F
difference, contact your local service distributor.
NOTE: Locate thermometer in same position for every
calibration. Position next to upper heating element is
recommended.
C. Thermostat Bulb Positioning
Keating’s patented thermostat application is accurate
within ±2°F of the dial setting between 250°F and
350°F. This accuracy is attained only if the thermostat
bulb is placed properly next to the top element using
element clamps. If the bulb is too far away from the
element, the fryer 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.
D. Hi-Limit Check
The manual Hi-Limit test button can be used to test the
Hi-Limit Control by pushing and holding the button in
until the fryer reaches the Hi-Limit temperature
(425°F). 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.
