GAS FRYER - SERIES PRE-2000
Oil Breakdown
As part of a “Preventive Maintenance Program”, the
oil in your fryer needs to be fi ltered 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 fi ltering, you can realize
substantial savings in oil costs as well as maintenance
charges.
LIMITED CALIBRATION
(Less than 25° difference)
You will need:
One screwdriver with 1/8" wide fl at blade
One accurate fryer thermometer

Thermostat calibration with knob on
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 three dial plate retaining screws,
rotate dial plate to match thermometer reading and
tighten screws. If it is more than 25°F off contact a
qualifi ed service company..
DO NOT ADJUST THE THERMOSTAT SET SCREW - IT
VOIDS ANY WARRANTY ON PART.
Thermostat Bulb Positioning
BEFORE REPLACING, TEST THERMOSTATS
NOTE: 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 14" Gas Fryers:
• The end of thermostat bulb should touch the
burner tube.
2.
For 10x11", 18" + Up Gas Fryers:
• 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.
overshoot.
• 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.

REQUIRED TEST THERMOSTAT
Multimeter (for testing continuity)
CHECKING CONTINUITY WITH THE MULTIMETER
1. Rotate the thermostat shaft until an audible click
is heard.
2. Rotate the thermostat shaft left and right ten
times causing the switch to click on and off ten
times, while using the Multimeter to verify continuity.
3. If the switch does not show continuity during all
ten trials, replace the thermostat.
DISASSEMBLING THE THERMOSTAT WILL VOID THE
THERMOSTAT WARRANTY.
1. Set compression ring onto capillary end of bulb
fi nger tight, 1/2" from end of capillary.
2. Insert new thermostat bulb through control panel
back.
3. Apply oil resistant fl exible sealant onto compres-
sion fi tting thread before installing fi tting into fryer
vessel.
