THERMOSTAT CALIBRATION
Checking Thermostat Calibration
The fryer themostat is carefully calibrated at the factory so that dial settings
match actual frying compound temperatures. Feld recalibration is seldom
necessary unless the unit has been mishandled in lransl or abused.
Recalibration should not be resorted to unless wnsidergble experience with
amking resuns definitety proves that the control is not maintaining the temperature to which the dial is set.
1. To check frying compound temperatures when recalibrating, use a precision
test instrument, or a good grade mercury thenometer. Fill fry tank wilh frying
compound to 'FULL' mark.
2. Flying compound temperature should b e checked at the center of the tank,
approximatety 1' to 1112' below surface of frying compound.
3. Turn the dial of the themstat being checked to the 350'F mark.
4. Allow temperature to stabilize, or until the thermostat cycles to 'OFF' three
times after starting with cokl frying oonpound. With power 'ON'. read highest
and lowest frying compound temperatures, as themstat cycles through at least
two cycles. Average the reading.
5. Thermostat s k u l d be recalibrated if temperature reading is not wlhin 10
degrees of the control knob selling (350'F 4- 1O0F).If recalibration is required,
continue wfih steps 6.7.8 and 9.
6. Remove control knob by grasping outer edgeand pulling straight oul, wilhoul
twisting or turning.
7.Hokl thermostat dial shaft 'B' (figura I ) stationary with pliers, and with a
screwdriver, turn screw 'A' clockwise to obtain a bwer temperature: or counterclockwise for higher temperature. Each 114 turn (90° rotation) of screw 'A'
represents 18'F.
8. Replace thermostat control knob
9. Recheck thermostat as in steps 4 and 5 above. If the fat temperature is not
within 20 degrees of dial setting (350°F +20°F),
I- it means that the sensing
element is inoperative and the themstatic control should be replaced.

Filling Fry Tank
. .
1. Ensure circuit breaker is at the 'ON' position. This is done by pressing the
'RESET or 'ON'part of the red rocker handle on the front panel.
2. Set the thermostat to 'OFF' and push in the red swilch marked 'ON-OFF' to turn
unit on. Red indicating light on the switch will come on. Turn the thermostat knob
to the 300" mark and a yellow cycling light marked 'HEAT ON' will come on.
Push the red swlch to turn it 'OFF'. The fryer control circuit has now been check
and the fryer is ready for use.
Caution: Do no1 leave elements on without frying compound in the tank.
I
a. Fill the fry lank to the 'FULL' rrork with approximately 30 lbs. of liquid or melted
frying compound. Do not overfill.
MAINTENANCE
NOTE: Do not use solid frying compound unless the fryer is equipped with a mett
cycle option. Air holes caused when packing solid frying compound into the fryer
can cause hot spots on the heating element sheath, resuling in momentary
ovemeatingof some of the frying campound and premature frying compound
breakdown. It can also damage the heating elements. If it is necessary to use
solid frying compound, it must be melled before &ding to fry tank.
Turn the thermostat to the desired frying temperature and push in the red 'ONOFF' switch to 'ON'. The yellow 'HUT ON' l~ghtwill stay on until the temperature set on the thermostat is rea:hed, then the light cycles off. The fryer is now
ready to begin frying. Afler a load has been fried, do not lower the next load into
the frying compound until the 'HEAT ON' light cycles off.
b. Do not allow frying compound level to drop more than 112' below the 'FULL'
mark. For proper operation of ltik fryer and go+ frying results, the frying compound level should be maintained.
c. Use a quality frying compound.
d. Filter the frying compound frequently, at least once a day.
e. Skim out food particles frequently with the strainerlskimmer.
I
-
1. Add at least 15% (of fry tank capacity) of fresh frying compound daily more if
possible without overloadina the tank. If 15% ot the frvina
- compound is not
-
?
bsed during hying, remove &me of the frying campound for other use (gravy.
griddle frying, etc.) to permit adding fresh frying compound.
g. Do not werkad the fry baskets. Approximately half-full or even less is correct. If
foods are taking longer 10 fry than lhe chart shows. or are n d browning. over-
kxding is a probable cause.
h. Prepare the food property:
i. Keep sah out of the frying wmpaund. Do not salt foods with the basket above
the kettle.
j. Assure a good thermostat operation.
k. Keep the fry tank and elements clean.
